What the science saysIntermittent Fasting for Skin and Acne

Reviewed on 11/10/2026

No trials show that intermittent fasting improves acne. The evidence is indirect: low-glycemic-load diets reduced lesions in small trials, and fasting has been linked with lower inflammatory markers. A 16:8 window may help if it cuts snacking and sugar, but it does not replace dermatological treatment.

In 43 young men with acne, 12 weeks on a low-glycemic-load diet cut lesions more than the control diet (−23.5 vs −12.0). [1]
In 32 patients, 10 weeks on a low-glycemic-load diet reduced inflammatory lesions and the size of sebaceous glands. [2]
In 50 healthy adults, the pro-inflammatory cytokines IL-1β, IL-6 and TNF-α dropped during Ramadan fasting. [3]

Frequently asked questions

Does intermittent fasting clear up acne?

It isn't an acne treatment, but it may help. Studies link insulin spikes and certain foods with more breakouts. Eating fewer times a day, without sweet snacking, helps many people get to calmer skin.

Should I talk to my dermatologist or doctor?

Yes, especially if your acne is moderate or severe, leaves marks, or if you take isotretinoin, antibiotics or birth control. Fasting can sit alongside your treatment, but never replace it. Your dermatologist will tell you how to combine them.

How long until I see it in my skin?

Skin renews in cycles of about 4-6 weeks, so changes are usually worth judging after 6-8 weeks of consistency. Before that, you may notice less shine.

Does fasting reduce inflammation?

Studies link intermittent fasting with lower markers of inflammation in the blood. In the skin, that may show up as less redness, though everyone responds differently.

Which foods can make acne worse?

For some people, sugar, refined flour and dairy, especially skim milk. Log your meals with photos and track your breakouts to find your own triggers.
