Inclusion criteria
Inclusion criteria: A systematic literature search is performed through scientific and clinical trial registries databases. The selection criteria are as follows. Participants (P): Healthy adults (excluding those under 18, pregnant women, and lactating women, who were not suffering from any diseases). Intervention (I): Skin exposure to UVand oral intake of foods (tablets, capsules, granules, beverages, processed foods) containing Astaxanthin. Compositions that also contain ingredients other than Astaxanthin as test substances are excluded. Astaxanthin intake should be 0.4-30 mg/day. Comparison (C): The comparison group is set up as consuming a placebo food that does not contain Astaxanthin. Outcome(O): The primary outcomes are minimal erythema dose (MED) and skin moisture content at UV-exposed sites, which are commonly used to evaluate the ability to protect skin from UV damage. Secondary outcomes are skin texture and roughness after UV exposure to determine the anti-UV effects comprehensively. Study design (S): Randomized, quasi-randomized, and non-randomized controlled trials (parallel group or crossover controlled trials) will be included.
