ConcentrationNot standardized to % L-ascorbic acid; sea-buckthorn derived
Supporting ActivesNiacinamide, Centella Asiatica, Hyaluronic Acid
Dr.Althea Vitamin C Boosting Serum is a Korean beauty vitamin-C serum featuring 640,000 ppm Hippophae Rhamnoides (sea buckthorn) water as its primary brightening active, paired with Tranexamic acid (TXA) for dark-spot reduction and Niacinamide for sebum control and pore refinement. The formula emphasizes gentleness over high-dose L-ascorbic acid, making it suitable for sensitive and all skin types.
Supporting actives: Centella Asiatica soothes stressed skin; Niacinamide refines texture. The serum is lightweight, absorbs smoothly, and oxidation-resistant (no yellowing or odor), with an opaque bottle.
Key benefits: Evens skin tone, revitalizes dull skin, soothes irritation, and minimizes pores. Vegan, paraben-free, cruelty-free.
Who it's for: Those seeking gentle, brightening vitamin-C care without irritation; sensitive-skin users; fans of K-beauty formulations. Current price: $16.73 (27% off typical $22.80), or $19.33 via Subscribe & Save—strong value for a 1.01 oz bottle.
