Sugars, far more than just a simple food sweetener, hold a significant role in skincare due to their moisturizing and protective properties. These molecules, such as glucose, act as natural humectants by drawing water into the skin, which helps to maintain optimal hydration.
What are the most commonly used sugars in cosmetics?
Glucose, fructose, trehalose, and hyaluronic acid are among the most popular sugars in skincare.
Why are sugars hydrating?
The moisturizing properties of sugars stem from their chemical structure, which is rich in hydroxyl groups (-OH). These groups enable sugars to attract and retain water through a hygroscopic effect. This not only keeps water on the skin's surface but also limits its evaporation.
Are sugar-based cosmetics suitable for oily skin?
Yes, sugars hydrate the skin without making it heavy, thus they are suitable for oily skin as well as other skin types.
Are naturally occurring sugars biodegradable?
Yes, sugars derived from plant sources such as beet or corn are biodegradable and environmentally friendly.
What is the typical concentration at which sugars are used?
The concentration of sugars in a skincare product varies from one treatment to another. However, they are generally found at concentrations between 2 and 5%, sufficient to hydrate the skin.
