Finding a serum that calms breakouts without stripping the skin can feel like an impossible task. Many acne-focused treatments rely on harsh ingredients that leave skin dry, irritated, and vulnerable. That’s where Dr. Althea 345 Relief Serum stands out. This Korean skincare favorite has earned a devoted following thanks to its ability to soothe blemish-prone skin while strengthening the skin barrier and delivering lasting hydration. ($22)
The real star of the formula is its carefully chosen blend of skin-repairing and anti-inflammatory ingredients. Niacinamide (Vitamin B3) helps regulate excess oil, reduce the appearance of post-acne marks, minimize the look of pores, and support a healthier skin barrier. It is one of the most studied skincare ingredients for improving uneven skin tone and reducing the visible effects of breakouts.
Another standout ingredient is Panthenol (Pro-Vitamin B5). Panthenol acts as a powerful humectant, drawing moisture into the skin while helping repair irritation and supporting the healing process. For blemish-prone skin that often becomes dry from acne treatments, panthenol provides welcome relief without feeling heavy or greasy. (Skinsort

The serum also features Centella Asiatica Extract, along with Centella-derived compounds such as Madecassoside, Asiaticoside, Asiatic Acid, and Madecassic Acid. These ingredients are widely known for their calming and redness-reducing properties. Together, they help soothe stressed skin and reduce the visible irritation that frequently accompanies acne flare-ups.
For those dealing with inflamed blemishes, Tea Tree Leaf Water provides an additional soothing benefit. Unlike stronger tea tree treatments that can be drying, the serum uses tea tree water in a lightweight formula designed to calm irritation while maintaining skin comfort.
Hydration is another major strength of the formula. Dr. Althea includes multiple forms of Hyaluronic Acid, which help attract and retain moisture in the skin. Combined with Beta-Glucan, the result is plumper, more comfortable skin that feels hydrated rather than tight. This is especially important because a well-hydrated skin barrier is often better equipped to handle breakouts and recover from inflammation.
The barrier-supporting ingredients don’t stop there. Ceramide NP, cholesterol, and phospholipids help reinforce the skin’s natural protective layer. A strong skin barrier can reduce sensitivity, improve moisture retention, and make blemish-prone skin less reactive over time.
What makes Dr. Althea 345 Relief Serum particularly appealing is that it balances acne care with skin comfort. Rather than aggressively attacking blemishes, it focuses on calming inflammation, supporting healing, reducing redness, and strengthening the skin barrier. The lightweight texture absorbs quickly and is suitable for sensitive skin types looking for gentle daily support.
