INGREDIENT LOG
Vitamin K in Skincare
Vitamin K is a fat-soluble vitamin hailed for its potential in promoting skin health by accelerating the skin's healing process and improving various skin conditions, including dark circles, rosacea, and spider veins.
Salicylic Acid in Skincare
Salicylic acid is a well studied BHA that exfoliates to encourage the shedding of top layer skin cells to help reveal younger and smoother looking skin. Used as a cosmetic ingredient as well as an OTC active for acne management.
Azelaic Acid in Skincare
Azelaic Acid is a dicarboxylic acid, different from alpha hydroxy acids and beta hydroxy acids, that acts as a “skin balancing ingredient” to address bioprocesses that are overreacting. It normalizes skin pigmentation, decreasing hyperpigmentation.
Sulfur in Skincare
Sulfur is a cosmetic ingredient and OTC acne active that is used to reduce sebum production, acne blemishes and the appearance of scars due to its ability to exfoliate. Sulphur acts as a keratolytic agent that can loosen the connection between the skin cells.
Retinaldehyde in Skincare
Retinaldehyde is a part of the retinoid family closest to retinoic acid on the conversion scale, making it more potent and bioavailable than retinol. It helps improve skin elasticity, increase gene expression for collagen synthesis, and visually reduce facial wrinkles.
