KEY INGREDIENTS

Refining that goes beyond exfoliation. Clearer, smoother skin.

AZELAIC ACID

A multifunctional acid that works differently from traditional exfoliating acids. It helps normalize the buildup of dead skin cells that can contribute to clogged pores while addressing breakouts, visible redness and uneven pigmentation—making it especially valuable for skin experiencing several concerns at once.

SALICYLIC ACID

An oil-soluble beta hydroxy acid that works within pores to help loosen pore-clogging buildup, reduce excess oil and improve the conditions that contribute to breakouts, including the environment in which C. acnes can proliferate. Helps leave congested skin clearer, smoother and more refined-looking.

SUPEROXIDE DISMUTASE (SOD)

A naturally occurring antioxidant enzyme and one of the skin’s own frontline defenses against oxidative stress. SOD helps neutralize highly reactive superoxide radicals before they can contribute to damaging oxidative reactions—helping protect skin from environmental stress while supporting a calmer, stronger and more resilient-looking complexion.

POTASSIUM AZELOYL DIGLYCINATE (PAD)

An advanced water-soluble derivative of azelaic acid that extends its benefits beyond traditional exfoliating. PAD helps regulate excess oil, improve the appearance of uneven pigmentation and visible redness, and promote a clearer, more balanced complexion—complementing azelaic acid through a different, highly skin-compatible form.

N-ACETYL GLUCOSAMINE (NAG)

A skin-identical amino sugar involved in the skin’s natural production of hyaluronic acid and essential components of the extracellular matrix. NAG supports hydration and healthy skin renewal while helping improve rough texture, uneven pigmentation and visible signs of photodamage

RED ALGAE

A nutrient-rich marine botanical naturally abundant in polysaccharides, minerals and skin-conditioning compounds. Red algae helps replenish hydration, soothe visible signs of stress and support barrier resilience—providing an important restorative counterbalance to the formula’s more active exfoliating ingredients.

HOW TO USE
