Dr. Althea 345 Relief Serum is a lightweight milky serum formulated for post-blemish redness, dehydration, uneven-looking texture, and easily stressed skin. The formula combines Niacinamide to support a clearer, more even-looking complexion with Panthenol to soothe dryness and strengthen the skin moisture barrier. Birch Juice and Tea Tree Leaf Water provide refreshing and conditioning care, while Centella Asiatica Extract and its key components Madecassoside, Asiaticoside, Asiatic Acid, and Madecassic Acid help comfort sensitive and blemish-prone skin. Multiple forms of Hyaluronic Acid including Hydrolyzed Hyaluronic Acid, Hyaluronic Acid, Sodium Hyaluronate, and Sodium Hyaluronate Crosspolymer help replenish and retain moisture for a smoother, more supple appearance. Ceramide NP, Cholesterol, Beta-Glucan, and Polyglutamic Acid provide additional barrier and hydration support, while Sodium DNA and Resveratrol contribute conditioning and antioxidant care. The fast-absorbing, non-sticky texture layers easily under moisturizer, sunscreen, or makeup and is non-comedogenic and sensitive-skin tested for comfortable daily use.
