What Is Skin Fasting - Trend, Truth & What Experts Say

Skin fasting - temporarily cutting back on skincare products — is gaining attention for helping the skin “reset.” Here’s what it means, how it’s done, who benefits, and when it can go wrong.

Highlights:

Skin fasting encourages pausing or simplifying skincare routines to reduce irritation and product overload
Experts advise keeping essentials like cleanser and sunscreen while skipping harsh actives
Evidence is limited; overdoing it or skipping protection can harm more than help

Skin fasting is a beauty trend built on doing less. It means pausing or reducing skincare products — sometimes down to just the basics — to let the skin’s barrier reset. The idea is that skin, when left to its own natural oils and microbiome, can recalibrate and function more efficiently. Japanese beauty brand Mirai Clinical is often credited with introducing the concept, promoting the idea that “less can be more” for a healthier complexion ().

How Skin Fasting Works for Barrier Repair

Overusing exfoliants, acids, or actives can sometimes irritate or thin the skin barrier. By cutting back, proponents believe the skin can:

Restore its oil balance
Reduce inflammation and redness
Recover from irritation or “product fatigue”

However, dermatologists clarify that skin fasting doesn’t mean abandoning all skincare. Gentle cleansing and daily sun protection should remain constants.

What Research Says About Skin Fasting

There’s little formal research on topical “skin fasting.” Most evidence is anecdotal or based on dermatologists’ clinical experience. However, experts agree that scaling back overactive routines can improve barrier recovery — provided essentials are maintained.

Unlike diet fasting, there’s no proven biological “reset” for the skin, but simplifying routines can reduce inflammation and improve tolerance over time.
