Keto-Carotenoid / Marine Carotenoid / HPA
A xanthophyll carotenoid from microalgae — considered one of the most potent natural antioxidants known. Uniquely spans the full width of cell membranes providing comprehensive lipid peroxidation protection. Clinical studies support topical and oral use for UV protection, anti-aging, skin texture and moisture. 6000x stronger than Vitamin C by some antioxidant measures.
This concentration sits at or below the 1% line — that's expected and effective for this ingredient. Below the 1% line isn't automatically fairy-dusting; some ingredients genuinely work at low doses.
Topical 0.02–0.1% in serums, AM and/or PM. Oral 4–12mg/day for systemic photoprotection and anti-aging benefits.
