What Is Biosaccharide Gum-3?

Biosaccharide Gum-3 is a naturally derived polysaccharide—a complex carbohydrate polymer—used in skincare formulations as a skin conditioning agent. It is structurally similar to other gum-based ingredients commonly used in cosmetics and functions primarily as a humectant, meaning it draws water from the environment into the skin's outer layers.

This ingredient is particularly valued in formulations where texture and hydration balance are priorities. It tends to create a lightweight feel on the skin whilst supporting the skin's natural moisture retention.

How It Works

Biosaccharide Gum-3 works by attracting water molecules from the surrounding environment and binding them within the skin's outer layer (stratum corneum). This hydration mechanism helps plump the skin slightly and can reduce the appearance of fine lines caused by dehydration.

Because it is a polysaccharide, it also has mild film-forming properties, which means it can help create a protective layer on the skin surface that slows transepidermal water loss—the natural evaporation of moisture from skin.

Clinical Evidence & References

Whilst polysaccharide humectants are well-established in skincare, specific clinical data on Biosaccharide Gum-3 as an individual ingredient remains limited in published literature. The evidence base relies largely on the ingredient's chemical structure and known behaviour of similar polysaccharide compounds in cosmetic formulations.

General research supports the use of polysaccharide humectants for improving skin hydration and maintaining skin moisture levels. However, efficacy may vary depending on formulation concentration, vehicle type, and individual skin characteristics.

How to Use

Biosaccharide Gum-3 is typically incorporated into serums, hydrating toners, and moisturisers where it works as part of a larger hydrating system. For best results, apply to clean, damp skin and follow with an occlusive moisturiser if you have dry skin, as humectants work most effectively when skin barrier function is intact. It suits both morning and evening routines and can be layered with other hydrating or active ingredients.

Safety & Precautions

Biosaccharide Gum-3 is generally well-tolerated and considered safe for use in cosmetics. It is unlikely to cause irritation, though as with any ingredient, patch testing is advisable for those with sensitive skin.
