Dr. Althea - 345 Relief Serum

Dr. Althea 345 Relief Serum is a Korean calming serum built around the brand's proprietary 3-4-5 Active System — 3 blemish-relief ingredients, 4 nourishing ingredients, and 5 soothing ingredients — designed to simultaneously address post-acne marks, repair the skin barrier, and calm irritation in one lightweight, fast-absorbing daily step.

The formula opens with Birch Sap (Betula Platyphylla Japonica) as the second ingredient — replacing a significant portion of the water base with mineral-rich, amino acid-packed Birch Sap that nourishes and hydrates more deeply than standard water. Paired with Tea Tree Leaf Water — the gentle, antibacterial distillate of Tea Tree that delivers calming and clarifying benefits without the dryness of concentrated tea tree oil — the dual-water base creates a uniquely soothing, skin-compatible foundation.

The Blemish Relief trio of Niacinamide, Resveratrol, and Tannic Acid targets post-acne marks, regulates sebum, refines pores, and evens skin tone. The Nourishing quad of PDRN (Sodium DNA), Ceramide NP, Beta-Glucan, and Quadruple Hyaluronic Acid (Hyaluronic Acid, Hydrolyzed Hyaluronic Acid, Sodium Hyaluronate, and Sodium Hyaluronate Crosspolymer) rebuilds the skin barrier and delivers lasting, multi-depth hydration. The Soothing 5 — Centella Asiatica, Madecassoside, Camellia Sinensis Leaf Water, Tea Tree Leaf Water, and additional PDRN — calm redness, inflammation, and sensitivity at every skin interaction.

Ceramide NP is delivered through a clinical-grade lipid complex of Hydrogenated Lecithin, Cholesterol, Lysolecithin, and Phosphatidylcholine — mimicking the skin's natural lipid bilayer for maximum penetration and barrier integration. Polyglutamic Acid (PGA) adds a next-generation moisture-locking layer, holding 4× more water than standard HA and forming a protective film on the skin surface. Pantothenic Acid (Vitamin B5), Xylose, and Beta-Glucan complete the formula with immune-calming and deep hydration support.

Non-comedogenic, sensitive skin tested, vegan, fragrance-free, paraben-free, silicone-free, and alcohol-free — suitable for all skin types, especially sensitive, reactive, and acne-prone skin seeking gentle yet comprehensive daily care.
