IACTIVE CSA is a versatile active ingredient that can be used in a variety of formulations. As an ester of salicylic acid, IACTIVE CSA works as an exfoliant to remove dead skin cells and reduce flaking. It also helps improve skin thickness and collagen production for a more youthful appearance. IACTIVE CSA's lipid solubility allows it to penetrate deeply and exfoliate pores from within, making it suitable for targeting blemishes, blackheads and other skin imperfections. As both an antimicrobial and anti-inflammatory agent, IACTIVE CSA is effective at controlling acne-causing bacteria while reducing irritation. Its non-irritating properties make it an ideal active for sensitive skin types. IACTIVE CSA helps condition and restore elasticity to damaged skin for a smoother, clearer and brighter complexion.
