Sente Defense C Serum is a clinically formulated antioxidant treatment designed to improve skin luminosity, support collagen synthesis, and protect the skin from oxidative stress associated with intrinsic ageing and environmental exposure. The  Sente Defense C serum is formulated with 20% Tetrahexyldecyl Ascorbate, a highly stable, lipid-soluble derivative of vitamin C that penetrates the skin efficiently while maintaining excellent tolerability, including in sensitive or compromised skin types. This form of vitamin C supports brighter skin tone, improved texture, and enhanced overall radiance without the irritation commonly associated with L-ascorbic acid.

The Vitamin C formulation is underpinned by Sente’s patented Heparan Sulfate Analog (HSA) Technology, which is designed to support the skin’s natural repair mechanisms and reinforce barrier integrity. HSA plays a key role in cellular communication and tissue recovery, making Sente Defense C Serum particularly well-suited to skin undergoing environmental stress, inflammation, or post-procedure recovery. By supporting barrier function, the serum helps improve skin resilience and tolerance.

An advanced antioxidant complex works synergistically within the Sente Defense C Serum formula to neutralise free radicals and reduce oxidative damage caused by ultraviolet exposure, pollution, and glycation processes. Ingredients such as Terminalia chebula fruit extract, rice bran extract, sunflower extract, rosemary extract, and vitamin E derivatives provide broad-spectrum antioxidant protection, helping to preserve collagen integrity and prevent premature skin ageing. Acetyl glucosamine contributes to hydration and supports a more even skin tone by assisting the skin’s natural renewal processes.

Sente Defense C Serum has a lightweight, fast-absorbing silicone-based delivery system that enhances ingredient stability and improves cosmetic elegance, allowing for seamless integration into both morning and evening treatment protocols. It layers well beneath moisturisers and sunscreens and is suitable for twice-daily use across all skin types, including sensitive, rosacea-prone, and post-procedure skin, when antioxidant support and barrier reinforcement are clinically indicated.

How to use: After cleansing, apply 1-2 pumps to the face and gently massage in. Use morning and evening.

Note: Due to the nature of Sente Defense C Serum, colour differences may vary over time. These changes do not affect the quality or safety of the product. Store at room temperature.
