Information
The serum's clinical efficacy is powered by a scientifically calibrated blend of acids and active ingredients, each selected for its targeted role. A cornerstone of the formula is 1.5% salicylic acid, a beta-hydroxy acid that penetrates deep into pores to dissolve impurities and reduce the appearance of blemishes. This is enhanced by 0.3% LHA (lipo-hydroxy acid), which provides even, controlled exfoliation to further decongest and refine the skin's surface texture. To address the visible signs of ageing, a synergistic blend of 3.5% glycolic acid and 0.5% citric acid works as an alpha-hydroxy acid complex to accelerate cellular turnover, smoothing fine lines and improving skin luminosity.
Crucially, the formula is fortified with 2% dioic acid, a naturally derived ingredient that targets one of the root causes of adult breakouts: excess sebum production. By helping to regulate oiliness at the source, it reduces the environment in which blemishes thrive, while also improving the appearance of blotchiness and post-inflammatory hyperpigmentation. This multi-acid technology works in concert to not only treat existing imperfections but also proactively prevent future congestion, all while promoting a more even, balanced, and youthful-looking complexion. The result is a comprehensive correction that refines pores, diminishes shine, and smooths ageing concerns without over-drying or compromising the skin's barrier.
Integrating Blemish + Age Defense into your routine is a strategic step towards lasting skin clarity and resilience. As an oil-free serum with a lightweight texture, it should be applied to clean, dry skin each morning and evening, using a few drops smoothed evenly over the entire face. Its fast-absorbing nature makes it an ideal base for moisturisers and sunscreens. Consistency is key; with daily use, you can expect a visible reduction in breakouts and excess oil, alongside a gradual improvement in skin texture and tone. This serum transcends the category of a simple spot treatment, offering instead a holistic regimen in a bottle for those who seek to conquer blemishes while proactively caring for their skin’s long-term youthfulness and radiance.
How to Use:
Once or twice daily, dispense 4-5 drops of Blemish + Age Defense into clean hands.
Cover the entire affected area with a thin layer of serum. If using in the morning, apply after a SkinCeuticals vitamin C antioxidant serum and before a SkinCeuticals sunscreen.
