Tetrahexyldecyl ascorbate is a form of vitamin C that’s been
modified to be more lipid soluble. This modification allows it
to better penetrate the skin. The problem with most topical
forms of vitamin C is they’re water soluble and can’t make it
through the lipid-rich skin barrier to reach the dermis of skin
where they could have maximal benefits. Tetrahexyldecyl
ascorbate is able to successfully penetrate the epidermis and
move to the layer underneath called the dermis. It’s in the
dermis that collagen, a protein that gives skin its youthful
firmness and ability to resist wrinkles, is made. Vitamin C has
a variety of benefits for health and for maintaining healthy,
youthful skin. It functions as an antioxidant, helping to offset
oxidative damage that degrades collagen and leads to wrinkles
and saggy skin. When skin is exposed to ultraviolet light from
the sun, a sequence of events occurs that leads to free radical
production. These free radicals damage skin cell membranes and
activate enzymes that break down
