Palmitoyl Ascorbyl Glucoside

Palmitoyl ascorbyl glucoside is a derivative of vitamin C (ascorbic acid) that has been chemically modified to improve stability and skin penetration. The molecule consists of ascorbic acid bonded to a palmitic acid chain and a glucose molecule, which together make it more shelf-stable than pure vitamin C whilst allowing it to work on the skin.As well as its antioxidant properties, this ingredient also functions as a humectant and emulsifier in formulations, meaning it helps draw moisture into the skin and keep products evenly mixed.

Helps with Dark Spots

Once applied to the skin, palmitoyl ascorbyl glucoside is broken down by skin enzymes to release free ascorbic acid (vitamin C). This process is slower than with some other vitamin C forms, which may result in gentler, more sustained activity on the skin.Vitamin C works as an antioxidant by neutralising free radicals and supporting collagen synthesis. The humectant properties help the skin's moisture barrier function by drawing water into the outer layers.

Apply to clean, dry skin in the morning or evening, or incorporate into your existing routine. Since this ingredient is more stable than ascorbic acid, it does not require special storage conditions. Allow the product to dry fully before applying other layers. Vitamin C products work well alongside sunscreen during the day and can be combined with other actives such as niacinamide or hyaluronic acid.

Generally well-tolerated across most skin types. As with any vitamin C product, patch test first if you have sensitive skin, as some users may experience mild irritation or dryness when starting out.
