Designed as the perfect precursor to Dr. Althea’s viral 345 Relief Cream, this serum takes a targeted, lightweight approach to barrier repair.

Rather than relying on heavy oils, it utilizes a milky, fast-absorbing texture that floods the skin with hydration and instantly drops the skin’s temperature to reduce redness. The formula combines Tea Tree Leaf Water and Heartleaf (Houttuynia Cordata) to rapidly soothe active acne and balance sebum production, while Centella Asiatica and Panthenol work to rebuild the microscopic tears in a damaged skin barrier. Fortified with Resveratrol—a potent antioxidant—and Niacinamide, it actively defends the skin against daily environmental stressors while fading the dark marks left behind by past breakouts.

It leaves the complexion feeling exceptionally calm, balanced, and deeply comforted, with zero tacky residue.

Ideal for: Redness & Irritation Relief, Acne & Sebum Balancing, Barrier Strengthening (Panthenol), Post-Blemish Brightening (Niacinamide), Lightweight Hydration.

  1. Use in both your morning (AM) and evening (PM) routines after cleansing and toning.
  2. Dispense 2–3 drops from the pipette onto your fingertips or directly onto the face.
  3. Gently press and pat the milky serum into the skin until fully absorbed.
  4. Pro Tip (Intense Soothing): If your skin is feeling particularly compromised, sunburned, or dry, apply two consecutive layers of the serum before sealing it in with a moisturizer.
