Tetrahexyldecyl Ascorbate (THDA) is a precursor of vitamin C. It is a powerhouse skincare ingredient renowned for its remarkable protective and corrective skin benefits.

It's an oil-soluble liquid that is highly stable. Unlike water-soluble L-ascorbic acid, this ingredient does not begin to degrade as soon as it comes into contact with light and air, so it won't be rendered inactive. 

In a recent study, THDA proved superior to L-ascorbic acid due to its lipid-soluble form that boasts excellent stability and penetration abilities, making it one of the best forms of Vitamin C in skincare. 

One of the primary benefits of Tetrahexyldecyl Ascorbate is its powerful antioxidant properties. As an antioxidant, it aids in neutralising free radicals, which are unstable molecules that cause oxidative stress and damage to the skin. By combating free radicals, THDA helps protect the skin from environmental aggressors such as pollution and UV radiation, thereby improving photodamaged skin and reducing the risk of premature ageing, including fine lines, wrinkles, and age spots

Furthermore, vitamin C plays a crucial role in collagen synthesis, a process vital for maintaining skin elasticity and firmness. Collagen is a protein that provides structural support to the skin, but its production naturally declines with age. By stimulating collagen synthesis, THDA helps promote a more youthful complexion, diminishing the appearance of sagging skin and improving overall skin health.

Another impressive skin benefit of THDA is that it possesses skin-brightening properties, making it an excellent ingredient for addressing hyperpigmentation and uneven skin tones. It inhibits the production of melanin, the pigment responsible for dark spots and discolouration, resulting in a more even and luminous complexion over time.

Additionally, THDA has anti-inflammatory properties that have a soothing effect on the skin, making it suitable for sensitive skin types. It can help calm redness and irritation while supporting the skin's natural barrier function.

Incorporating this powerhouse skincare ingredient into your routine can lead to a multitude of benefits, including improved skin texture, a more even skin tone, and a more youthful, radiant appearance. Applying a Vitamin C Serum in the morning is a valuable addition to any skincare regimen that can offer skin brightening, protection and visible results for a healthier, more vibrant complexion.
