A gentle daily exfoliating serum that smooths rough texture, softens the look of fine lines, and brightens a dull complexion.

Its 7.7% multi-acid blend of alpha and beta hydroxy acids (AHAs and BHAs, which loosen dead surface cells) speeds up skin renewal, while 1% taurine, an amino acid, helps keep skin hydrated and supports the barrier. SkinCeuticals found smoother, clearer-looking skin within a week.

Use once a day, morning or night, after cleansing and before your antioxidant serum and moisturizer; always follow with SPF, since acids increase sun sensitivity. Gentle enough for daily use, and tested to prepare skin ahead of professional peels, which makes it a useful first step before an in-clinic treatment.

Size: 30 mL
Best for: all skin tones; rough texture, dullness, uneven tone, and early fine lines
Use: once daily, AM or PM, before serums and SPF
Results: SkinCeuticals reports smoother, more radiant skin in about a week
