- Gently press 2 to 3 drops of the serum into your skin and let it absorb for a minute.
- Apply the serum on clean, dry skin to help manage your blemishes safely.
- Do a patch test before your first use and avoid the delicate eye area.

What the research says
A moisturizer containing licochalcone A, 1,2-decanediol, L-carnitine, and salicylic acid significantly reduced noninflammatory, inflammatory, and total acne lesion counts compared to a vehicle control in Thai patients during a 12-week maintenance phase.
