What food can and can't do for wrinkles
Food plays a supporting role, not a starring one. Polyphenol-rich foods and healthy fats showed small, bias-free reductions in wrinkles in pooled 2025 trial data. But the effects are modest, some sources tested were oils or extracts rather than whole foods, and no food erases wrinkles or replaces sun protection.
What food can do
- ✓ Polyphenol-rich foods (cocoa, green tea, citrus, pomegranate, grapes) — small pooled wrinkle reduction, no publication bias1
- ✓ Healthy fats (flaxseed, avocado; some oils) — a slightly larger reduction, also bias-free1
- ✓ Supply raw materials (protein, vitamin C) and modest UV photoprotection (carotenoids)
What food can't do
- ✗ Erase wrinkles — the effects are small, and sources mix foods with oils and extracts
- ✗ Match the collagen-supplement wrinkle number — that's a supplement, and it's bias-limited1
- ✗ Beat the real levers — sun protection, not smoking, sleep
Where this comes from
- Why the topic gets over-promised
- The biggest wrinkle number in the reviews belongs to collagen — pooled standardised mean difference −0.94.1 But that came from collagen peptide supplements, and it showed strong publication bias and very high variability, so the reviewers cautioned against it. "Anti-wrinkle foods" marketing borrows that number and pins it on food. The honest food signal is smaller and quieter.
- What the human evidence shows
- The anchor is a 2025 meta-analysis of 61 studies — 77% randomised trials — of diet and skin ageing.1 For wrinkles, two groups gave significant reductions with no sign of publication bias: healthy fats (pooled SMD −0.62) and polyphenols (−0.48) — small-to-moderate effects. Vitamins and probiotics showed no significant wrinkle effect. So some food components genuinely help a little; the sources that carry the signal are polyphenol-rich foods and healthy fats. A second 2025 review agrees the larger gains trace to supplements, not foods.2
- Where the evidence stops
- The effects are modest, the studies are heterogeneous, and many are before-and-after rather than against a control group. Crucially, the "food" categories mix whole foods (cocoa, green tea, flaxseed, avocado) with concentrated oils and extracts (grape-seed and pine-bark extracts, evening primrose and sea buckthorn oils), so the whole-food-only effect is likely smaller still. And wrinkles are driven mainly by sun, smoking and age — which diet cannot undo. No food erases them.
The honest order of priorities: the biggest anti-wrinkle steps aren't on your plate — daily sun protection, not smoking, and good sleep do far more than any food. Eat polyphenol-rich foods and healthy fats because they're good for you and give skin a modest hand, not because they will smooth wrinkles. We recommend no supplement, and we sell nothing.

Bottom line for you
Food can give your skin a modest hand with wrinkles — polyphenol-rich foods like cocoa, green tea, citrus, pomegranate and grapes, and healthy fats from flaxseed and avocado, showed small but genuine reductions in pooled trial data, with no sign of publication bias. That's worth doing, because those foods are good for you anyway.
Just keep the scale honest. The effects are small, some of the trial "sources" were oils and extracts rather than whole foods, and nothing you eat erases wrinkles or undoes sun damage. The biggest wins are sun protection, not smoking and good sleep. We recommend no anti-wrinkle supplement, and we sell nothing.
