About the Product

Blemish + Age Defense is a powerful, oil-free serum designed for adult skin that’s both breakout-prone and affected by visible signs of ageing. This formula blends 2% dioic acid with a strategic combination of alpha-hydroxy acids (AHAs) and beta-hydroxy acids (BHAs), including salicylic, glycolic, and citric acids.

The Science Behind Adult Blemishes

Adult breakouts are often triggered by hormonal shifts, stress, or environmental factors. Increased sebum production and impaired skin renewal contribute to clogged pores, blemishes, and post-inflammatory pigmentation.

Blemish + Age Defense addresses these root causes while also reducing fine lines and promoting a more youthful, even skin tone.

Adult Acne DOs + DON’Ts

  • DO: Combine blemish and anti-ageing care.

    • AHAs like glycolic and citric acid target both blemishes and signs of ageing.

  • DON’T: Use a one-size-fits-all approach.

    • Adult breakouts often require a multi-targeted solution that addresses hormonal and environmental factors.

Blemish-Fighting Partners

Pair Blemish + Age Defense with professional treatments like chemical peels to promote faster skin cell turnover. This serum complements in-clinic procedures by supporting long-term improvements in blemishes, texture, and radiance.

INGREDIENTS

Key Ingredients

  • Paraben Free

  • Oil-Free

  • Dye-Free

  • Fragrance-Free

2% Dioic Acid

Derived from vegetables, dioic acid helps regulate excess sebum production—reducing oiliness and helping to control blemishes at the source.

0.3% LHA (Caproloyl Salicylic Acid)

Also known as Lipo-Hydroxy Acid, LHA provides gentle, targeted exfoliation. It works on the surface of the skin to unclog pores, refine texture, and encourage healthy cell turnover.

1.5% Salicylic Acid (BHA)

A beta-hydroxy acid that deeply penetrates into pores to dissolve oil and debris. This helps reduce existing blemishes while preventing new breakouts from forming.

3.5% Glycolic Acid + 0.5% Citric Acid

These alpha-hydroxy acids (AHAs) work synergistically to smooth skin texture, refine surface roughness, and diminish the appearance of fine lines and uneven tone. Together, they enhance radiance and clarity.
