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.
 
This multi-acid approach helps reduce the formation of blemishes, smooth the appearance of fine lines and wrinkles, and improve skin tone and radiance. By regulating excess oil and targeting roughness, this serum visibly improves skin texture and clarity.

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.
