Yon-Ka's serums are high-tech, lightweight products with higher concentrations of active ingredients. Yon Ka's serums are formulated to improve texture, lighten dark spots, diminish fine lines and wrinkles or boost hydration. Applied after cleansing, Yon-Ka serums penetrate quickly for dramatic results.

Botanical extracts and antioxidants help to reduce inflammation, regulate the level of oil in the skin and brighten the complexion. Retinoids in a serum will act as a messenger to cells deep within your skin, prompting increased production of collagen and elastin, and reducing the depth and appearance of fine lines and wrinkles. Alpha hydroxy acids (AHAs) stimulate skin cell turnover, promote the health of the new skin cells that replace the dead skin cells, and help with fading hyperpigmentation and melasma.
