As intermittent fasting gains traction for health and weight loss, TikTok beauty enthusiasts have jumped on a similar concept for skincare: ‘skin fasting.’
The idea, which has garnered thousands of TikTok videos, suggests taking breaks from all skincare products, sometimes for 24 hours, sometimes for an entire week, under the premise that allowing the skin to ‘reset’ will clear up blemishes and reduce redness. But can avoiding skincare products really give your complexion a boost? Not according to Anshul Gambhir, a beauty expert at Gambhir Cosmetic Medicine. He explains that the ‘skin fasting’ trend could do more harm than good.
“A well-maintained skincare routine is the key to healthy skin. Skin thrives on a stable, consistent regimen rather than a complete withdrawal from products,” says the expert.
While the expert appreciates the intention behind ‘skin fasting’ — allowing the skin to naturally regulate itself — he stresses that simply eliminating all skincare items isn’t the way to achieve this.
“Cleansers, moisturisers, and especially sunscreens aren’t just optional extras. They’re vital in counteracting the constant environmental stressors, such as pollution and the blue light from screens, that our skin faces daily.”
Without these basic protective products, our skin is left vulnerable to damage from these external factors.
“It would be a different story if we lived without pollution, sunlight, or HEV light, but that’s not our reality,” Anshul tells us, adding that a minimalist routine is far better than skipping skincare altogether. For those thinking of abandoning their routines due to breakouts or irritation, he suggests seeking out gentle, non-comedogenic products rather than going ‘cold turkey’ with skincare.
“If ‘skin fasting’ seems to be helping, that’s likely because some of the products you were using weren’t suitable for your skin type,” he explains.
Instead, he recommends a straightforward routine: a gentle cleanser, moisturiser, and sunscreen in the morning, followed by cleansing, a targeted serum, and moisturiser in the evening.
“Cleansing clears away makeup, dirt, and pollutants, while serums with ingredients like vitamin C offer antioxidant protection,” he advises.
The expert also advises adding a mild exfoliator to the mix. “Exfoliation is key because, with regular SPF or makeup use, the skin’s natural turnover process slows down.”
In some cases, like with perioral dermatitis or other skin sensitivities, paring back products can be helpful. “If you’re struggling with specific skin conditions, certain ingredients like fragrances, strong acids, or peels might be irritating,” he says.
“However, even in those cases, a simple cleanser, moisturiser, and SPF routine is usually best.”
