Taking astaxanthin supplements (a red-orange antioxidant pigment found in salmon and shrimp) every day for 1-4 months doesn't seem to make wrinkles noticeably shallower in middle-aged people, according to research that combined results from multiple clinical trials.

Systematic Review and Meta-Analysis on the Effects of Astaxanthin on Human Skin Ageing

Systematic Review With Meta-Analysis

2021 Aug 24

This study tested whether taking astaxanthin pills by mouth helps reduce wrinkles. The results show that astaxanthin did NOT significantly reduce wrinkle depth (the study found the same statistics the claim mentioned: SMD = -0.26, p=0.11). This means the study SUPPORTS the claim that oral astaxanthin doesn't significantly reduce wrinkles.

A study said astaxanthin might help with skin aging and wrinkles, but the data wasn't strong enough to prove it - the wrinkle reduction result wasn't statistically significant.

Scientists looking at studies on astaxanthin for skin aging found that the research so far has problems: the results vary too much between studies, not enough people were tested, and it's hard to tell if the studies were done properly.

A natural red pigment called astaxanthin, found in seafood, might help keep skin looking younger when applied to the skin or taken by mouth, but scientists haven't done good enough studies yet to know for sure.
