What you eat and your skin
Most diet-and-skin claims are folklore. One has a randomized controlled trial behind it, and it's about blood sugar rather than chocolate or grease.
Glycemic load and acne
A randomized controlled trial in the American Journal of Clinical Nutrition found a low-glycemic-load diet improved acne compared with a conventional diet. For acne-prone skin, blood-sugar-spiking eating patterns are a legitimate lever — modest next to proven topicals, but real.

What actually outranks diet here
The strongest controlled evidence in skin belongs to sunscreen — an Australian randomized trial found daily use produced measurably less skin aging over four and a half years — and to topical tretinoin, established in a double-blind vehicle-controlled JAMA trial back in 1988. No dietary change in the literature approaches either.

Weight-loss medication and skin
Rapid weight loss changes facial volume, which is the real mechanism behind the phenomenon the internet nicknamed 'Ozempic face'. It is a volume effect, not a skin-quality effect, and it is a reason to lose weight at a sustainable pace with adequate protein rather than a reason to avoid treatment.
What to actually do
- Sunscreen daily is the highest-evidence, cheapest anti-aging intervention that exists.
- Acne-prone: a lower-glycemic pattern has RCT support; it complements topicals rather than replacing them.
- Generic tretinoin with any prescription costs a fraction of custom-formula subscriptions.
- Smoking accelerates skin aging in consistent observational data; nothing topical offsets it.
