20% Tetrahexyldecyl Ascorbate
The central active within Vita-C Lipid.
Tetrahexyldecyl Ascorbate, often abbreviated to THD Ascorbate, is a stable, lipid-soluble Vitamin C derivative.
It provides antioxidant protection while supporting brighter-looking skin, more even tone and collagen-related processes.
Because it is lipid soluble, it can be incorporated into an oil-based formulation without requiring the very acidic pH commonly used for pure L-Ascorbic Acid serums.
The 20% refers to Tetrahexyldecyl Ascorbate itself and should not be interpreted as equivalent to a 20% pure L-Ascorbic Acid formula. They are different forms of Vitamin C with different formulation and delivery characteristics.
Squalane
A lightweight, skin-compatible emollient that helps replenish surface lipids and reduce moisture loss.
It supports softness and comfort without the heavy feel associated with some traditional oils.
Jojoba Seed Oil
Simmondsia Chinensis Seed Oil provides emollient support and helps maintain skin suppleness.
Its wax-ester composition has good affinity with the skin's natural surface lipids.
Bisabolol
A soothing ingredient that helps calm visible irritation and support skin comfort.
Its inclusion is especially valuable in a Vitamin C serum specifically positioned for sensitive skin.
Ginger Root Extract
Zingiber Officinale Root Extract provides complementary antioxidant and soothing support.
It helps strengthen the formula's wider defence against environmental oxidative stress.
Lightweight Lipid Base
Coconut Alkanes, Coco-Caprylate/Caprate, C12-15 Alkyl Benzoate and Caprylic/Capric Triglyceride create the silky, water-free delivery system.
These ingredients provide emollient slip and help the serum spread easily without requiring a conventional aqueous serum base.

Use morning and/or evening.
After cleansing, allow the skin to dry.
Apply 2–3 drops directly onto the face using the dropper.
Massage gently until evenly distributed and absorbed.
