BHA (Beta Hydroxy Acids) and LHA (Lipo Hydroxy Acids) are gentle, oil-soluble exfoliants that penetrate deep into pores to remove excess sebum and impurities. They help smooth skin texture, reduce blemishes, and refine skin texture while respecting the skin barrier. Ideal for combination to oily or blemish-prone skin, they leave skin clear, balanced, and radiant.
