The serum companion to Dr. Althea's bestselling 345 Relief Cream (154 reviews, 4.8★) — delivering the same Calm + Hydrate + Barrier Care philosophy in a lightweight, fast-absorbing serum format. Formulated for sensitive, acne-prone, and post-blemish skin. Non-comedogenic. Fragrance-free. Vegan.

• Birch Sap + Tea Tree Leaf Water — Dual Calming Waters — Birch Sap is naturally rich in minerals, amino acids, and vitamins that hydrate and soothe irritated skin. Tea Tree Leaf Water delivers gentle anti-bacterial and anti-inflammatory calming without the dryness of concentrated tea tree oil. Together they form the lightweight aqueous base of this serum — calming from the first layer.
• Panthenol + Niacinamide + Beta-Glucan — The 345 Active Core — Panthenol (Pro-Vitamin B5) deeply hydrates and supports barrier healing. Niacinamide brightens post-blemish marks, controls sebum, and strengthens the moisture barrier. Beta-Glucan calms immune response and delivers deep moisture. These three are the backbone of the 345 Relief line.
• PDRN (Sodium DNA) + Ceramide NP — Barrier Regeneration — PDRN supports skin cellular regeneration and repair at a deeper level. Ceramide NP replenishes the barrier lipids that acne, over-exfoliation, and sensitivity deplete. Together they rebuild the skin barrier from within.
• Madecassoside + Centella Asiatica + Resveratrol + Hydrolyzed HA — Madecassoside is the most potent isolated centella active for calming redness. Centella Asiatica Extract extends the soothing and barrier-support action. Resveratrol provides antioxidant protection. Hydrolyzed HA delivers surface-level moisture.

After toner, apply a moderate amount evenly over face and gently pat for better absorption. Use before the 345 Relief Cream as a daily serum step. Fragrance-free. Vegan. Non-comedogenic.
