Potassium Palmitoyl Ascorbyl Glucoside

Potassium palmitoyl ascorbyl glucoside is a modified form of vitamin C, created by attaching a palmitoyl (fatty acid) group and a glucose molecule to ascorbic acid. This chemical modification makes it more stable than pure vitamin C, allowing it to remain effective for longer in skincare formulations without oxidising or degrading.In skincare products, it functions as both an active ingredient and a formulation helper. It can deliver vitamin C benefits to the skin whilst also acting as an emulsifier and humectant, helping to bind water into the skin and improve the texture of a formula.

Helps with Dark Spots

The ingredient penetrates the skin where it may be converted into active vitamin C through enzymatic processes. Vitamin C is a known antioxidant and cofactor in collagen synthesis, meaning it helps protect skin cells from environmental stress and may support the skin's structural integrity over time.As a humectant, the glucose and palmitoyl components also help the skin retain moisture by attracting water molecules to the stratum corneum, which can improve hydration and skin texture appearance.

This ingredient is typically used as part of a complete skincare routine rather than in isolation. It works well in serums, moisturisers, and toners. For best results, apply to clean skin before heavier creams or oils. There is no need to adjust usage based on concentration, as formulations are designed with stability and efficacy already balanced in.

Generally well-tolerated across skin types, including sensitive skin. No significant cautions are documented, though patch testing before full use is always sensible for those prone to irritation.
