Tetrahexyldecyl ascorbate is a derivative of vitamin C. Because it’s fat-soluble, it can penetrate the skin better than pure vitamin C. It’s also a more stable version of vitamin C, meaning it has a longer shelf life and isn’t as affected by temperature, light, and exposure to oxygen. This ingredient neutralizes free radicals that are damaging to the skin, supports collagen production, and reduces the appearance of melasma.
Tetrahexyldecyl ascorbate is best for topical anti-aging and dark spot correcting skin creams. This ingredient helps to reduce wrinkles and fine lines by boosting collagen production. It works to reduce melasma and even out dark spots and hyperpigmentation. Because it’s oil-soluble, it can be used in oil-based skincare products. It’s also a good alternative for people who have irritation with other forms of vitamin C.
Tetrahexyldecyl ascorbate does not have many drawbacks. It has been shown to be less irritating to most people’s skin than other vitamin C analogues, though it is possible those with sensitive skin or allergic reactions to the ingredient can experience redness and irritation.
A scar can form anywhere the skin is broken deeply enough to damage surrounding skin cells. With acne, most superficial blemishes will heal cleanly, leaving no visible evidence of prior breakouts. However, in the case of cystic acne, when a clogged pore leads to infection that travels deep into the dermis, ruptured cysts can break the follicle wall and cause the infection to damage surrounding skin cells. Collagen helps to repair the damage but leaves the skin more firm and tight than the rest of your skin. Some types of acne scarring leave a concave shape, called a pockmark. Contrary to some belief, not all acne scars are caused by picking or popping your blemishes. Some occur even if the acne is allowed to heal without picking.
To prevent sun damage from making acne scars more visible, it’s best to moisturize daily and wear sunscreen. Additionally, antioxidants protect the skin from free radicals that damage cells and speed up aging. Ingredients and nutrients like acai oil, alpha-lipoic acid, green tea extract, retinol/vitamin A, coenzyme Q10, caffeine, alpha-hydroxy acid and salicylic acid are all beneficial for preventing and reducing acne scarring. Jojoba oil is also good for reducing inflammation, fighting bacteria, and keeping in moisture for healthier skin.
tetrahexyldecyl ascorbate may be effective for acne scars, but there are many other factors that may affect whether this ingredient would work on your skin or if there are better ingredients that may work for you.
