Sugars

Glucose, fructose, trehalose and hyaluronic acid are among the most popular sugars in cosmetics.

The moisturizing properties of sugars originate from their chemical structure, which is rich in hydroxyl groups (–OH) that enable them to attract and hold water through a hygroscopic effect. This not only helps maintain water at the skin’s surface but also limits its evaporation.

Yes, sugars hydrate the skin without weighing it down and are therefore suitable for oily skin as well as other skin types.

Yes, sugars obtained from plant sources, such as beet or corn, are biodegradable and environmentally friendly.

The concentration of sugars in a cosmetic product varies from one formulation to another. However, they are generally present at levels between 2% and 5%, sufficient to hydrate the skin.

An excess of dietary sugars promotes glycation, a chemical process that alters proteins such as collagen. This can contribute to a loss of elasticity and an earlier onset of visible signs of aging. However, the impact depends on numerous metabolic factors.

Glycation refers to the non-enzymatic binding of sugars to structural proteins. It leads to the formation of advanced glycation end products that stiffen dermal fibers. This phenomenon is part of the skin aging process.

A diet high in simple sugars can modulate certain hormonal and inflammatory pathways. This may foster an environment conducive to skin imperfections in some individuals. However, responses remain variable among individuals.

Yes, certain sugars and polysaccharides exhibit film-forming and moisturizing properties that are beneficial to the hair fiber. They can improve hair flexibility and also help enhance its shine.
