Anhydrous vitamin C combo
in a waterless silicone base
Stable topical ascorbic acid compositions. (Enter this patent number: 6146664 , in the search field).
"Ten patients having facial photodamage were recruited for a double-blind pilot study of a newly formulated vitamin C ,complex having 10% ascorbic acid, a water soluble acid, and 7% tetrahexyldecyl ascorbate, a lipid soluble analog.
Both of these are combined in an anhydrous polysilicone gel base, which acts as a 'dermal patch,' releasing the water soluble acid slowly and the lipid soluble analog rapidly. The active vitamin C complex was applied to one side of the face and the inactive placebo base was applied to the opposite side of the face once a day." Fitzpatrick RE, Rostan EF. Double-blind, half-face study comparing topical vitamin C and vehicle for rejuvenation of photodamage. Dermatology Associates of San Diego County, Inc. 92024, USA. Read more
About Vitamin C derivatives
"There is some evidence that combining water soluble and oil-soluble forms of vitamin C may provide synergistic skin benefits through broader antioxidant protection and better penetration." Dr. G. Todorov, Anhydrous Vitamin C Combo, smartskincare.com
"Most vitamin C derivatives on the market, including ascorbyl palmitate and magnesuim ascorbyl phosphate, consist of the ascorbic acid fragment (ascorbyl) and a fragment of another acid (e.g. palmitate or phosphate). Recent research indicates that new vitamin C derivatives, such as Tetrahexyldecyl Ascorbate, consisting of multiple chemical fragments bound to a single ascorbic acid fragment may work even better. These new derivatives are more stable compared to both vitamin C and older derivatives. Furthermore, some of these newcomers (particularly the so-called tetrasubstituted lipophilic ascorbates) also appear to be more powerful boosters of collagen synthesis." Dr. G. Todorov, Vitamin C Derivatives, smartskincare.com
