Taking astaxanthin supplements (a natural red pigment found in salmon and shrimp) every day for 1 to 4 months can make your skin more stretchy and elastic if you're middle-aged and noticing early signs of skin aging.

Taking astaxanthin pills (about 2-12 mg daily for 1-4 months) can help middle-aged people's skin stay more moisturized, according to research combining 5 different experiments.

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.

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.

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.
