iS Clinical GeneXC Serum

GeneXC Serum stands apart with its proprietary Extremozyme technology – DNA-repairing enzymes clinically proven to protect and revitalise skin at the cellular level. Combined with 20% L-Ascorbic Acid, Kakadu Plum (containing 100x more vitamin C than oranges) and mixed fruit acids, it delivers comprehensive antioxidant protection whilst improving fine lines, firmness and radiance. The formula is also designed to be gentler than many high-strength vitamin C serums.

For those seeking advanced anti-ageing benefits, GeneXC Serum is an exceptional choice. Its combination of high-potency vitamin C with Extremozyme technology addresses multiple ageing concerns simultaneously – brightening, firming, protecting and repairing. The formula works to prevent future damage whilst visibly improving existing signs of ageing, making it ideal for both prevention and correction.

Despite its potent 20% vitamin C concentration, GeneXC is formulated to be well-tolerated by most skin types including sensitive skin. Many users report no stinging or irritation – just a lightweight, watery texture that absorbs quickly. The formula includes soothing botanical extracts like Green Tea that help calm the skin. If you're particularly sensitive, start with every other day application and build up as your skin adjusts.

Many users notice an immediate improvement in skin radiance and texture after just a few applications. For more significant improvements in fine lines, firmness and hyperpigmentation, expect to see visible results within 4-8 weeks of consistent twice-daily use. Long-term benefits including enhanced skin health and protection continue to improve with ongoing use.

Absolutely. GeneXC works beautifully within an iS Clinical routine. For enhanced hydration, mix it with Hydra-Cool Serum before applying. Use after Cleansing Complex and before your moisturiser. It pairs well with Active Serum for comprehensive skin renewal, though introduce products gradually to allow your skin to adjust.

Store GeneXC Serum in a cool, dark place away from direct sunlight. Some users prefer to keep it refrigerated, which can help maintain optimal potency and provides a refreshing application experience. Always ensure the cap is tightly closed after use. The serum should maintain its efficacy throughout its use when stored properly.

Yes, GeneXC is excellent for addressing uneven skin tone and hyperpigmentation. The 20% vitamin C works to inhibit excess melanin production whilst the Kakadu Plum extract enhances brightening effects. Combined with the gentle exfoliating action of the mixed fruit acids, you can expect a more even, luminous complexion with continued use.

Yes, always apply a broad-spectrum SPF after using GeneXC Serum during the day. Whilst vitamin C actually provides some antioxidant protection against UV damage, it's not a substitute for sunscreen. Using both together offers enhanced protection and helps prevent further hyperpigmentation and ageing.
