Sugars

Sugars, far more than mere culinary sweeteners, occupy an important place in cosmetics thanks to their hydrating properties. These molecules, such as glucose, act as humectants that attract and retain water in the skin, helping to maintain proper moisture levels in the stratum corneum.

FAQ about sugars

Which sugars are most commonly used in cosmetics?

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

Why do sugars have hydrating properties?

The hydrating properties of sugars arise from their chemical structure, which is rich in hydroxyl (-OH) groups that enable them to attract and retain water through a hygroscopic effect. This not only helps to maintain water on the surface of the skin but also limits its evaporation.

Are sugar-based cosmetics suitable for oily skin?

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

Are naturally derived sugars biodegradable?

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

At what concentration are sugars generally used?

The concentration of sugars in a cosmetic formulation varies from one product to another. Nevertheless, they are typically present at concentrations between 2% and 5%, which is sufficient to hydrate the skin.

What is the effect of a high sugar intake on 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 to the earlier onset of visible signs of ageing. However, the impact depends on numerous metabolic factors.

What is cutaneous glycation?

Glycation refers to the non-enzymatic bonding of sugars to structural proteins. It leads to the formation of advanced glycation end products that stiffen the fibres of the dermis. This phenomenon is part of skin ageing.

Do sugars influence the appearance of imperfections?

A diet high in simple sugars can modulate certain hormonal and inflammatory pathways. This may foster conditions favourable to imperfections in some individuals. Responses, however, vary between individuals.

Do sugars have any beneficial effects on hair?

Yes, certain sugars and polysaccharides have film-forming and moisturising properties that benefit the hair fibre. They can improve hair flexibility and may also help to enhance its shine.
