The most expensive serum cannot fix what your diet is undoing. Skin is the body’s largest organ, and it shows what’s going in.
The shortlist
- Avocado. Healthy fats for barrier function. Half a day, every day.
- Wild salmon. Omega-3s reduce inflammation and improve skin elasticity. Twice a week minimum.
- Berries. Antioxidant punch in the lowest-sugar fruit category.
- Walnuts. The plant version of the salmon argument — omega-3s plus vitamin E.
- Sweet potato. Beta-carotene, which the body converts to vitamin A — basically internal retinol.
- Green tea. Polyphenols that protect against UV damage. Two cups a day.
Skip the supplements. Eat the food. The skin will catch up.
