Vitamin C Ester
A fat-soluble form of Vitamin C that offers antioxidant support for the skin.
Also known as: Ascorbyl Palmitate • Ester-C
Overview
Vitamin C Ester refers to forms of Vitamin C that are bound to a fatty acid, making them fat-soluble (lipophilic). The most common form is ascorbyl palmitate. This property allows it to be more easily incorporated into cell membranes, potentially offering better antioxidant protection within the lipid-rich environment of the skin. It is used both orally and topically to support collagen synthesis, protect against UV damage, and brighten the complexion. Some branded forms like Ester-C also contain metabolites that may enhance bioavailability and retention.
Key Benefits
Supports Collagen Production
Vitamin C is an essential cofactor for the enzymes that build and cross-link collagen fibers.
Provides Antioxidant Protection
As a potent antioxidant, it neutralizes free radicals, protecting skin from oxidative stress and photoaging.
Brightens Skin
It can inhibit the enzyme tyrosinase, helping to reduce melanin production and fade dark spots.
Dosage & How to Take
500-1,000 mg per day is a common dosage for general health and skin benefits.
