Cyclopentasiloxane is a silicone used to improve texture and trap moisture. An easier name for this is D5.

D5 is considered lightweight and volatile. Volatile means it evaporates quickly after application. Once evaporated, D5 leaves a thin barrier that helps keep skin hydrated.

D5 is an emollient. Emollients help soften the skin and prevent water loss. Silicones create a silky texture in products. D5 helps other ingredients become more spreadable.

Studies show D5 is safe to use in skincare products. We recommend speaking with a skincare professional if you have concerns.

The phospholipids in our skin can be naturally depleted. Replenishing the phospholipids in our skin can help hydrate your skin. Due to their hygroscopic nature, they act as humectants and emollients. Humectants draw moisture from the air to your skin, while emollients help trap moisture in. This ingredient is non-occlusive.

Studies show phospholipids display antioxidant activity and may help with reducing the signs of aging.

Phospholipids are complex lipids that contain glycerin, two fatty acids, and a phosphate group. Some foods that contain phospholipids include soybeans and milk. The phospholipids found in soy come from Lecithin. This ingredient can also be synthetically created.
