PHA (Polyhydroxy Acids) are a gentle class of exfoliating acids, related to AHAs (Glycolic Acid) but with a larger molecular size that makes them ideal for sensitive skin. They remove dead skin cells, improve skin texture, and boost hydration without irritation. Suitable for dry, reactive, or rosacea-prone skin, PHAs support a healthy skin barrier and offer anti-aging benefits. Perfect for skincare beginners or those who can’t tolerate traditional AHAs or BHAs.


LHA (Lipo Hydroxy Acid) is a gentle derivative of salicylic acid (BHA) known for its targeted exfoliation and anti-inflammatory properties. With a slow penetration rate, it offers controlled exfoliation, unclogs pores, refines skin texture, and reduces breakouts—without irritation. Ideal for sensitive, acne-prone, and oily skin, LHA helps balance sebum while promoting a clear and even complexion.
