- Glycolic Acid: An exfoliating acid that helps remove dead skin cells, improving skin texture and promoting cell turnover. Renowned for its potent exfoliating abilities, glycolic acid works by gently dissolving dead skin cells, promoting smoother texture, minimizing the appearance of pores, and encouraging cell turnover for a radiant complexion.
- Salicylic Acid: A beta-hydroxy acid (BHA) known for its ability to penetrate pores, making it effective for treating acne and unclogging pores. A go-to for acne-prone skin, salicylic acid’s oil-soluble nature allows it to penetrate deep into pores, effectively unclogging them and reducing inflammation, making it a powerhouse for treating breakouts.
- Lactic Acid: A gentle exfoliating acid that helps improve skin texture, reduce the appearance of fine lines, and promote a brighter complexion. With a gentler touch, lactic acid exfoliates the skin’s surface, revealing brighter skin and promoting collagen synthesis, making it a great choice for those seeking a softer exfoliation.
