We Tried Skin Fasting for 7 Days—Here's Our Verdict
Scroll through beauty social media and you'll encounter a counterintuitive trend: skin fasting—the deliberate reduction or complete elimination of skincare products for a period of time. Proponents claim it allows your skin to "reset," "detox," and remember how to function independently without the crutch of products. Skeptics argue it's just a recipe for dehydration, breakouts, and damaged skin barriers.
As skincare enthusiasts who've seen trends come and go, we decided to test skin fasting ourselves. Three women with different skin types—dry, oily, and combination—committed to seven days of dramatically simplified skincare routines to see what actually happens when you step away from your carefully curated regimen.
Our experiences ranged from surprisingly positive to predictably problematic, offering valuable insights about when skin fasting might help, when it definitely hurts, and what this trend reveals about modern skincare culture.
What Is Skin Fasting?
Before diving into our experience, let's clarify what skin fasting actually means, as definitions vary:
Strict Skin Fasting: Completely eliminating all skincare products—no cleansers, no moisturizers, nothing—for a set period. You might wash with water only or not wash at all.
Modified Skin Fasting: Dramatically simplifying your routine to bare essentials, typically just cleanser and perhaps a basic moisturizer, eliminating all "active" ingredients and treatment products.
Intermittent Skin Fasting: Taking regular breaks from your full routine, such as one day per week with minimal products, or fasting overnight while maintaining a morning routine.
The practice originated in Japan and Korea, where it's seen as a way to counteract overuse of skincare products and allow skin to self-regulate. The philosophy suggests that constant application of products can make skin "lazy" and dependent, impairing its natural functions.
For our experiment, we chose modified skin fasting for safety: water cleansing only, no moisturizers, serums, or treatments, and sunscreen was allowed when spending significant time outdoors (because sun protection is non-negotiable for skin health).
Meet Our Testers
Sarah, 34 - Dry, Sensitive Skin Normal routine: Oil-based cleanser, hydrating toner, hyaluronic acid serum, peptide serum, rich moisturizer with ceramides, overnight sleeping mask Skin concerns: Dryness, fine lines, occasional redness Expectations: Nervous about how her already-dry skin would handle no moisturizer
Maya, 28 - Oily, Acne-Prone Skin Normal routine: Salicylic acid cleanser, niacinamide serum, lightweight gel moisturizer, benzoyl peroxide spot treatment, retinol three times weekly Skin concerns: Large pores, blackheads, occasional breakouts, oiliness Expectations: Hoped reduced products might help reduce oiliness and breakouts
Jessica, 41 - Combination Skin Normal routine: Gentle cleanser, vitamin C serum, hyaluronic acid, moisturizer, retinol alternative, eye cream Skin concerns: Fine lines, uneven tone, T-zone oiliness with dry cheeks Expectations: Curious whether her skin would balance itself without intervention
Day 1-2: The Adjustment Period
Sarah (Dry Skin):
"By the end of Day 1, my skin felt tight and uncomfortable after washing with just water. I kept reaching for my moisturizer out of habit. By Day 2, I noticed visible flaking around my nose and forehead. My skin looked dull and felt rough to the touch. The tightness was constant and distracting. I was already questioning this decision."
Maya (Oily Skin):
"Day 1 felt oddly liberating. My face actually didn't feel as oily by the evening as it usually does with products. Day 2, I woke up with skin that looked... surprisingly normal? Maybe even a bit better? I was producing oil, but it didn't seem excessive. No new breakouts yet. I was cautiously optimistic."
Jessica (Combination Skin):
"The first day was fine, though I felt naked without my routine. By Day 2, my T-zone was definitely oilier than usual by afternoon, but my cheeks felt dry and tight. The combination was uncomfortable. I noticed my makeup sat differently on my skin—patchier in some areas."
Day 3-4: Reality Sets In
Sarah (Dry Skin):
"Day 3 was when things got really uncomfortable. The flaking spread to my cheeks and chin. My skin was so tight it almost hurt. Fine lines looked more pronounced. I was drinking extra water, but it wasn't helping. By Day 4, I was dealing with red, irritated patches on my cheeks. My skin barrier was clearly compromised. The tightness and discomfort were constant."
Maya (Oily Skin):
"Day 3, I noticed my skin texture looked better—smoother, with less visible texture. My pores looked slightly smaller. I was still producing oil, but not as much as with my full routine. However, by Day 4, I started noticing small bumps forming on my forehead—not quite pimples yet, but concerning. My skin also felt slightly dehydrated despite the oil production."
Jessica (Combination Skin):
"Day 3 and 4 were when the uneven texture became obvious. My dry areas were getting flaky while my oily areas were producing more sebum than usual. The contrast was stark. I developed a few small breakouts along my jawline, probably from touching my face more as I adjusted to the bare feeling. I wasn't enjoying this."
Day 5-6: The Turning Point
Sarah (Dry Skin):
"By Day 5, I seriously considered quitting. The irritation was worsening. My skin felt raw. However, I pushed through to see the full seven days. Day 6 brought a slight improvement—the angry redness calmed a bit, but the dryness and flaking persisted. My skin looked years older than it did a week earlier. I couldn't wait for this to end."
Maya (Oily Skin):
"Days 5 and 6 were interesting. The small bumps from Day 4 didn't progress into full breakouts and actually started subsiding. My skin continued producing less oil than with my full routine. The texture improvement was noticeable. I actually started wondering if I'd been over-treating my skin with too many products. However, I also noticed my skin felt less supple and slightly dehydrated despite the oil."
Jessica (Combination Skin):
"By Days 5 and 6, I'd adjusted somewhat. My skin seemed to reach a kind of equilibrium—still producing oil in the T-zone and dry on the cheeks, but not worsening. The small breakouts were healing. My skin tone looked uneven without my vitamin C serum, and fine lines were more visible. I missed my products but could see why some people might appreciate the simplicity."
Day 7: The Final Day
Sarah (Dry Skin):
"Day 7 couldn't come fast enough. My skin was dry, flaky, irritated, and aged-looking. The moment midnight hit, I cleansed properly and applied my full hydrating routine. My skin drank it up like it had been in a desert—which, essentially, it had. This experiment confirmed what I already knew: my dry skin absolutely needs moisturization and barrier support. Skin fasting is NOT for dry skin types."
Maya (Oily Skin):
"Finishing Day 7, I was genuinely surprised. My skin looked better than when I started—clearer, less congested, with improved texture and smaller-looking pores. I was producing less oil. The dehydration I'd noticed didn't progress. I learned that my elaborate routine might have been too much for my skin. However, I also noticed I was missing the protective benefits of my products, and I would never maintain this long-term."
Jessica (Combination Skin):
"Day 7 brought relief that it was ending and reflection on what I'd learned. My skin didn't thrive without products, but it didn't catastrophically fail either. The experience made me realize I might be using products I don't actually need. Some simplification could be beneficial, but complete elimination wasn't the answer for me."
The Results: One Week Later
After completing our skin fasting and returning to our normal routines, we gave our skin a week to stabilize before assessing the lasting effects.
Sarah (Dry Skin):
"It took four days of intensive hydration to repair the damage from skin fasting. My skin barrier had been significantly compromised, requiring extra care to restore. One week post-fast, my skin is back to baseline—no better, definitely temporarily worse. This experiment showed me that dry skin genuinely needs external support. The idea that skin can 'learn' to hydrate itself is nonsense for dry skin types. Would I try this again? Absolutely not."
Maya (Oily Skin):
"One week after returning to my routine, I've modified it based on what I learned. I eliminated one serum I don't think I needed, simplified my morning routine, and my skin has maintained the improvements from the fast. I'm producing slightly less oil and experiencing fewer breakouts. The texture improvement has persisted. Skin fasting taught me I was probably overwhelming my skin with too many products. However, I'm now using a basic moisturizer—complete elimination isn't sustainable. Would I try fasting again? Maybe a shorter version as an occasional reset."
Jessica (Combination Skin):
"Post-fast, I've streamlined my routine to focus on products that actually make a difference. I'm using fewer products in the morning and have seen my skin balance slightly better. The dramatic difference between product overload and no products taught me to find a middle ground. Would I try fasting again? Possibly a modified version, but I'd never eliminate products completely."
What Dermatologists Say About Skin Fasting
We consulted board-certified dermatologists about skin fasting to put our experiences in professional context:
Dr. Jennifer Lee, Board-Certified Dermatologist: "Skin fasting can be useful in specific situations—particularly for people who've damaged their skin barriers through over-exfoliation or use of too many active ingredients simultaneously. In these cases, simplifying or temporarily eliminating products allows the barrier to repair. However, the idea that skin needs to 'detox' or that normal skincare makes skin 'lazy' isn't scientifically accurate. Skin doesn't develop dependence on moisturizer or become incapable of functioning. For people with inherently dry skin, conditions like eczema, or those using necessary treatment products for acne or aging, skin fasting can be counterproductive and potentially harmful."
Dr. Marcus Chen, Dermatologist and Skincare Researcher: "What skin fasting actually reveals is whether someone's routine is appropriate for their skin type. If elimination of products leads to improvement, it usually means the routine was too aggressive or included irritating ingredients. If skin deteriorates without products, it indicates those products were addressing real needs. Rather than all-or-nothing fasting, I recommend strategic simplification—identifying which products genuinely benefit your skin and eliminating those that don't."
Who Might Benefit from Skin Fasting
Based on our experience and expert input, skin fasting might help:
People with damaged skin barriers from over-exfoliation, too many acids, or irritating products Those using excessive products without understanding what each does People with resilient, normal-to-oily skin who might be overwhelming their skin with unnecessary treatments Anyone experiencing unexplained irritation or sensitivity that might be product-related Those wanting to identify which products in their routine actually make a difference
Who Should Avoid Skin Fasting
Skin fasting is problematic for:
People with dry or very dry skin types who need external moisturization Those with eczema, psoriasis, or other skin conditions requiring consistent treatment Anyone using prescription treatments for acne, rosacea, or other issues People with compromised skin barriers from medical treatments or environmental damage Those with mature skin benefiting from anti-aging ingredients Anyone in harsh climates (very dry, cold, or highly polluting environments)
What We Learned: Key Takeaways
1. Skin Type Matters Enormously Our drastically different experiences highlight that skin type determines whether fasting helps or hurts. One size definitely does not fit all.
2. Many People Use Too Many Products Maya's positive results suggest that overcomplicated routines can be counterproductive. More products don't always mean better results.
3. Some Products Are Necessary, Some Aren't Skin fasting helped us identify which products our skin genuinely needed versus which we used out of habit or hope.
4. Your Skin Barrier Is Crucial Sarah's damaged barrier from just seven days shows how important protective products are for some skin types.
5. Sunscreen Is Still Non-Negotiable Even during skin fasting, sun protection remains essential. This shouldn't be eliminated under any circumstances.
6. "Natural" Isn't Always Better The romantic idea that skin can perfectly self-regulate without any support ignores individual variation and environmental stressors our ancestors didn't face.
7. Simplification ≠ Elimination The real lesson isn't to eliminate skincare but to be intentional about what you use and why.
Our Modified Approach: Sustainable Simplification
After this experiment, we've each developed more sustainable approaches:
Sarah continues her full routine but has simplified slightly, focusing on barrier support and hydration without redundant products.
Maya permanently simplified her routine, using fewer products that her skin actually needs, and occasionally does "mini-fasts" of 24 hours to check in with her skin's needs.
Jessica streamlined to products that make visible differences, eliminated those that didn't, and feels more confident about her simplified routine.
The Verdict: Is Skin Fasting Worth Trying?
Yes, if:
- You have normal to oily skin
- You suspect you're using too many products
- You've damaged your skin barrier through over-treatment
- You're experiencing unexplained irritation
- You're willing to modify the fast if things go wrong
- You understand it's an experiment, not a miracle cure
No, if:
- You have dry or very dry skin
- You have skin conditions requiring consistent treatment
- You use prescription skincare
- You're in a harsh climate or environment
- You're not willing to accept potential setbacks
Maybe, with modifications:
- Try intermittent fasting (one day per week) rather than extended periods
- Simplify rather than eliminate completely
- Keep essential barrier support products
- Never eliminate sun protection
The Bottom Line
Skin fasting taught us that the relationship between products and skin health is nuanced and individual. For Maya, it revealed product overload and led to lasting improvements. For Sarah, it confirmed that her skin genuinely needs support. For Jessica, it clarified which products matter and which don't.
The takeaway isn't that everyone should fast or that fasting is universally harmful. It's that intentional simplification—thoughtfully evaluating what your skin actually needs versus what marketing or trends tell you to use—is valuable for everyone.
Your skin doesn't need to "detox," but your routine might benefit from evaluation. Rather than eliminating everything, consider whether each product serves a purpose for YOUR skin, not someone else's or some idealized version of perfect skin.
Skincare should support your skin's health and your life, not overwhelm either. Whether that means ten steps, three steps, or occasionally taking a break, the right answer is the one that works for your unique skin, lifestyle, and goals.
Medical Disclaimer: This article is for informational and entertainment purposes only and is not intended as medical advice, diagnosis, or treatment. The personal experiences described represent individual anecdotes from specific skin types and conditions and should not be interpreted as recommendations applicable to all readers. Skin fasting can be harmful for certain skin types, conditions, and situations. Individual skin needs vary dramatically based on skin type, age, climate, health status, existing skin conditions, medications, and numerous other factors. Always consult with a qualified dermatologist or healthcare professional before significantly altering your skincare routine, eliminating products your skin may need, attempting skin fasting, especially if you have existing skin conditions, use prescription skincare products, have dry or sensitive skin, or are unsure whether skin fasting is appropriate for you. Never discontinue prescription skincare treatments without consulting the prescribing physician. The experiences shared in this article do not constitute professional dermatological advice. What worked or didn't work for our testers may not apply to your skin. If you choose to attempt skin fasting despite these warnings, monitor your skin closely and discontinue immediately if you experience worsening symptoms, severe dryness or irritation, painful skin, compromised skin barrier, or any concerning changes.
Sun Protection Disclaimer: Sun protection should never be eliminated regardless of skincare trends or fasting experiments. UV exposure causes skin cancer, premature aging, and other damage. Even when simplifying or eliminating other skincare products, continue using broad-spectrum sunscreen with at least SPF 30 daily when exposed to sun. The testers in this article maintained sun protection during their experiment despite eliminating other products.
Individual Results Disclaimer: The experiences described in this article represent three individuals with specific skin types, ages, and conditions during one week in specific environmental conditions. Results from skin fasting vary enormously between individuals. Some people may experience improvements, others may see no change, and many will experience worsening skin conditions during product elimination. Do not expect to achieve the same results as any person described in this article. Your skin is unique and will respond differently.
Not a Substitute for Professional Care: This article does not replace professional dermatological evaluation, diagnosis, or treatment. If you have skin concerns, acne, signs of aging, skin conditions, or any dermatological issues, consult a board-certified dermatologist who can provide personalized, evidence-based recommendations rather than following trends or anecdotal experiments.
Skin Barrier Damage Risk: Eliminating necessary products, particularly moisturizers and barrier repair ingredients, can damage your skin barrier, leading to increased sensitivity, inflammation, moisture loss, infection risk, and long-term skin problems. Barrier damage can take weeks or months to fully repair. Do not take skin barrier health lightly or assume damage will easily reverse.
Product Dependency Myths: The concept that skin becomes "dependent" on or "lazy" from using skincare products is not supported by scientific evidence. Dry skin will not suddenly learn to produce more oil if you eliminate moisturizer. Skin with naturally low ceramide or lipid production will not spontaneously increase production just because you stop applying products. While over-treatment with harsh or unnecessary products can cause problems, appropriate skincare supports rather than impairs natural skin function.
Climate and Environmental Considerations: The safety and appropriateness of skin fasting depends heavily on your environment. Harsh climates (very dry, very cold, highly polluted, or intense sun exposure) make skin fasting significantly riskier and potentially more damaging. Environmental factors your ancestors didn't face—air pollution, indoor heating and air conditioning, chlorinated water, and synthetic fabrics—mean modern skin often requires more support than historical humans needed.
Age Considerations: Skin changes significantly with age. Mature skin produces less oil, has reduced barrier function, and loses structural proteins like collagen and elastin. Eliminating supportive skincare from aging skin can accelerate visible aging, increase dryness, and compromise already-weakened barriers. Skin fasting is generally more appropriate for younger skin with robust barrier function and adequate sebum production.
Prescription Skincare Warning: Never discontinue prescription skincare products including retinoids for acne or aging, topical antibiotics, rosacea treatments, or medications for other skin conditions without explicit approval from your prescribing physician. These treatments address specific medical conditions and stopping them without supervision can cause flares, worsening conditions, or treatment resistance.
Photography and Perception: The subjective assessments of skin improvement or worsening in this article are based on personal perception and limited photography. Professional dermatological assessment using standardized photography, skin analysis tools, and objective measures would be necessary to scientifically verify claimed improvements or damage. Personal perception is influenced by expectations, lighting, and bias.
Trend Caution: Skin fasting is a trend that gained popularity through social media rather than clinical research or dermatological recommendation. Be skeptical of skincare trends promoted primarily through social platforms without scientific backing. What's popular isn't always what's effective or safe.
Emergency Situations: If you experience severe reactions during skin fasting including signs of infection (increasing redness, warmth, pus, fever), severe pain or burning, extensive rash or hives, difficulty breathing, or signs of anaphylaxis, seek immediate medical attention. Do not wait or attempt to treat severe reactions at home.
