Pearltide
ITRI Patented Technology Application: Extracting『PearltideR』 from Oyster Shells for Eco-Friendly Reuse and Outstanding Skincare Effects
Extracted from oyster shells’ pearl layer, PearltideR has undergone rigorous safety tests, including skin safety, EUREACH SVHC, heavy metal, and microbial inspections. The 100% Pearltide solution is non-irritating, non-allergenic, inhibits melanin production and tyrosinase activity, repairs UVA-damaged epidermal cells, and promotes pro-collagen formation while suppressing collagen-degrading enzyme MMP-1 expression. When used in skincare products, it delivers remarkable beauty and skincare benefits, significantly enhancing skin condition.
