A next-gen group of acids, PHAs (real name: polyhydroxy acids) have a multitude of skin benefits: they exfoliate, encourage cell turnover and hydrate.
Lactic acid could be the most hydrating chemical exfoliant: it boosts the level of ceramides—hydrating lipids—that sit on the skin’s surface and increases water retention.
Glycolic acid is most effective for correcting sun damage, smoothing fine lines, as well as reducing acne, dullness, oiliness and uneven skin texture.
Salicylic Acid neutralises bacteria from within the pores before it develops into a blemish. It also attacks the skin’s ‘glue’, allowing it to eliminate dead skin cells while clearing congestion and soothing irritated skin.
