What Is It?

Tetrahexyldecyl Ascorbate is an ingredient you might see on the label of some advanced skincare products, and it's essentially a form of Vitamin C that's been specially modified for stability and absorption.
​Think of traditional Vitamin C (ascorbic acid) as being like a fresh-cut apple slice – very beneficial, but it can brown and lose its potency quickly when exposed to air and light. Tetrahexyldecyl Ascorbate is like that same apple slice, but with a protective coating that keeps it fresh and effective for much longer.

What are the benefits?

The "Tetrahexyldecyl" part makes this Vitamin C oil-soluble. Because our skin also has natural oils, this oil-soluble form can more easily blend with and be absorbed into the skin's surface layers, allowing it to work effectively there.
Firstly, it acts as an antioxidant, helping to protect the skin from the visible effects of environmental stressors like pollution and UV exposure, which can contribute to signs of aging and dullness. This can lead to a more radiant-looking complexion. Secondly, regular use of cosmetic products with this ingredient may help to improve the appearance of uneven skin tone and diminish the look of dark spots, promoting a brighter and more uniform skin appearance. Ultimately, by enhancing visible skin vitality and smoothness, it can contribute to a more youthful and refreshed look."
