Dr. Althea 345 Relief Serum is a lightweight daily calming and barrier-repair serum specially formulated to soothe irritation, deeply hydrate, and strengthen the skin barrier in one simple step. Its fast-absorbing, non-sticky texture makes it ideal for sensitive, acne-prone, oily, combination, and dehydrated skin, providing long-lasting comfort without clogging pores. The serum is non-comedogenic and tested for sensitive skin.

The name "345" reflects its carefully selected ingredient system:

• 3 Blemish-Care Ingredients: Niacinamide, Resveratrol, and Tannic Acid
• 4 Nourishing Ingredients: Beta-Glucan, Hydrolyzed Hyaluronic Acid, Ceramide NP, and Sodium DNA (PDRN)
• 5 Soothing Ingredients: Tea Tree Leaf Water, Camellia Sinensis Leaf Water, Madecassoside, Centella Asiatica Extract, and Sodium DNA

These ingredients work together to calm redness, reduce post-acne marks, replenish moisture, and reinforce the skin's protective barrier.

The serum is enriched with Birch Sap, Tea Tree Leaf Water, and Panthenol (Vitamin B5) to deliver immediate soothing and hydration. Multiple forms of Hyaluronic Acid, including Hydrolyzed Hyaluronic Acid, Hyaluronic Acid, Sodium Hyaluronate, and Sodium Hyaluronate Crosspolymer, provide multi-layer hydration that leaves skin plump and comfortable throughout the day.

Barrier-supporting ingredients such as Ceramide NP, Cholesterol, Hydrogenated Lecithin, Centella Asiatica, Madecassoside, Asiaticoside, Asiatic Acid, and Madecassic Acid help strengthen the skin's natural defense while improving resilience against environmental stress. The addition of Sodium DNA (PDRN) helps support skin recovery and overall skin health.

Clinical testing by the brand reports improvements in hydration and soothing while maintaining a 0.00 irritation score, making this serum an excellent choice for weakened skin barriers, redness, and post-acne recovery.
