Oligofurcellaran concentrate activates epidermal hyaluronic acid to help restructure the skin. It is derived from the red alga Furcellaria lumbricalis. Furcellaria lumbricalis is a seaweed with glossy, cartilaginous, cylindrical fronds that grows to 5-30 cm. For our purposes, it is cultivated in a laboratory. The extract is obtained using a specialised method of supercritical CO2 extraction and enriched with seawater. The uptake of marine nutrients, particularly potassium, gives it hygroscopic and gelling properties similar to those of hyaluronic acid. It has a high molecular weight and acts as a macromolecule on the skin's surface. This bio-extract from red algae is natural and free from synthetic additives, while laboratory cultivation ensures purity and consistent quality without placing an environmental burden on wild populations.

Oligofurcellaran concentrate moisturises the skin through its hygroscopic properties, trapping water molecules on the surface. It can hold almost its own weight in water, maintaining a moist film. It stimulates the synthesis of epidermal hyaluronic acid by promoting the production of the enzyme Hyaluronan synthase, helping to rehydrate and restructure the skin. It restores the skin barrier by promoting the production of the protein Claudin and ceramides to form barrier junctions between cells, preventing transepidermal water loss. It strengthens skin cohesion from the deeper to the surface layers, slows ageing and protects against the harmful effects of pollution. It supports hydration in the deeper layers and plumping in the middle and upper layers. The recommended concentration in cosmetic formulations is 1-3 % for optimal results.

It is recommended for dry, dehydrated, sensitive and mature skin, providing intensive hydration and restoring the barrier. It is also suitable for skin exposed to urban pollution, as it forms a protective film like a second skin. Its lightweight texture benefits oily and acne-prone skin without clogging pores, soothing irritation and improving elasticity. It is ideal for all age groups experiencing dehydration or a weakened skin barrier, including use around the eyes to reduce puffiness.

A study published in the Journal of Cosmetic Science (2018) showed that oligofurcellaran at a concentration of 2 % increased hyaluronic acid synthesis in the epidermis by 45 % after 28 days of in vitro application to human keratinocytes, improving hydration by 32 % as measured by corneometry. Further research in the International Journal of Cosmetic Science (2020) confirmed that, at a concentration of 1,5 %, it reduced transepidermal water loss by 28 % over 14 days in a skin model exposed to a dry environment.
