AHA, BHA, PHA, and LHA are a family of exfoliating acids that work together to smooth, clarify, and renew the skin. AHAs (Alpha Hydroxy Acids), like glycolic and lactic acid, gently remove dead skin cells on the surface for brighter, softer skin. BHAs (Beta Hydroxy Acids), such as salicylic acid, penetrate deep into pores to clear excess oil and prevent breakouts. PHAs (Polyhydroxy Acids) offer mild exfoliation with added hydration, making them perfect for sensitive skin. LHAs (Lipo Hydroxy Acids) provide ultra-gentle, slow-release exfoliation that refines texture and minimises clogged pores. Together, they leave the complexion smooth, clear, and radiant without stripping the skin’s natural moisture barrier.
