    Starting out
    Every other evening for two weeks, then nightly if comfortable. Not on a retinoid night. Daily SPF. Reactive skin: twice a week for the first month.

    • AHA (Glycolic Acid)An alpha hydroxy acid that gently dissolves dead skin cells at the surface, improving skin texture, brightening dark spots, and promoting a smoother, more even complexion.
    • BHA (Betaine Salicylate)A beta hydroxy acid that penetrates into pores to dissolve congestion, reduce blackheads, and help prevent breakouts.

    After cleansing, apply to a cotton pad and sweep gently across the face, avoiding the eye area. Do not rinse off. Use 2–3 times per week in the evening. Always follow with SPF the next morning.

    A dual-action exfoliating toner that uses both AHA and BHA to resurface, refine, and clarify the skin. AHA gently dissolves dead skin cells at the surface for a brighter, smoother complexion, while BHA penetrates deep into pores to remove congestion and reduce blackheads. The result is visibly clearer, more even skin with regular use — without the harshness of physical exfoliants.
