Glycogen
What is Glycogen?
Glycogen is a polysaccharide that serves as a form of energy storage in humans and animals. It is primarily found in the liver and muscles but can also be sourced from marine animals for use in products.
In skincare, glycogen is used for its moisturizing properties. It can help to support the skin's hydration by potentially replenishing naturally occurring glycogen levels, although the scientific evidence on its efficacy in topical applications is limited.
When you see glycogen on a label, it's helpful to know that it's typically included for its potential skin-conditioning benefits. However, as it can be derived from animals, it may not be suitable for vegans.
Commonly found in: body lotions, face creams, anti-aging creams, moisturizers
Benefits
- May support skin hydration by acting as a humectant.
The FDA does not specifically regulate glycogen in cosmetics, treating it as a common cosmetic ingredient.
Research on glycogen's efficacy in topical formulations is limited and inconclusive.
Glycogen is typically sourced from animals, making it unsuitable for those following a vegan lifestyle.
