Blemish + Age Defense

Salicylic acid acne serum


An oil-free face serum that reduces the formation of adult acne, and improves visible signs of aging 

Product Details

  • 2% Dioic Acid
    Naturally derived from vegetables, this ingredient helps reduce excess sebum
  • 0.3% LHA (caproloyl salicylic acid)
    A lipo-hydroxy acid, LHA, evenly exfoliates skin, decongests pores, and refines the skin’s surface
  • 1.5% Salicylic Acid
    A beta-hydroxy acid refines pores and helps reduce the formation of acne
  • 3.5% Glycolic Acid and 0.5% Citric Acid
    These alpha-hydroxy acids work synergistically to smooth skin and minimize the appearance of fine lines and wrinkles


Once or twice daily, apply four to five drops to dry skin.

Blemish + Age Defense is a targeted, oil-free approach for aging skin prone to breakouts. This first-to-market acid blend combines 2% dioic acid with an optimal alpha- and beta-hydroxy acid formulation to reduce the formation of acne and clogged pores, while improving the appearance of fine lines, wrinkles, and uneven skin tone.

Blemish & Age Defense provides an elegant and effective option for my mature patients who still suffer from acne. It not only resolves their acne, it simultaneously reduces oiliness, unclogs pores, brightens skin color, and improves fine lines and skin texture. This light serum layers nicely with the other SkinCeuticals products my patients are using in order to prevent signs of aging.
