A lightweight, oil-free face serum that combines 10 % niacinamide (vitamin B3) with cica (Centella Asiatica) extract and other supportive ingredients to control excess oil, calm irritation, and refine skin texture. This serum is designed especially for oily, acne-prone, or combination skin types — balancing sebum production while targeting blemishes, enlarged pores, and dull tone without clogging pores.
