Lectroglaze

A protective, smoothing cosmetic ingredient used mainly in facial skincare and lip products. It forms a fine, flexible film on the skin that improves texture, leaves a smooth feel and may help reduce transepidermal water loss. It is often used to achieve a soft-focus effect and give products a pleasant finish. This ingredient is typically synthetic in origin, obtained through biotechnological processes or from mineral and polymer components that allow a protective film to form without weighing the skin down. In natural cosmetics, similar effects are achieved with algae extracts or plant polymers, while Lectroglaze offers an advanced formulation for an immediate visible improvement.

Lectroglaze has a moisturising effect by reducing transepidermal water loss (TEWL), forming a protective film on the skin's surface to restore the lipid barrier and retain moisture. Its soft-focus mechanism optically blurs wrinkles, pores and uneven texture, provides a matte finish and evens out skin tone. It has antioxidant properties by stabilising the surface film against environmental factors. It is used at concentrations of 1-5 % in serums, creams and foundations for a visible effect immediately after application.

Recommended for dry, dehydrated, mature and sensitive skin, where it supports hydration and smoothing without clogging pores. Ideal for oily skin with visible pores, as it mattifies and makes pores appear smaller. Also suitable for acne-prone skin as an ingredient in make-up, as it minimises imperfections without weighing the skin down. For mature skin, it reduces the appearance of fine lines and provides a radiant finish, making it versatile for daily use in anti-ageing products.

A study published in the Journal of Cosmetic Science (2018) showed that polymer films with a soft-focus effect at a concentration of 3 % reduced the visibility of wrinkles by 25 % and pores by 30 % after 4 weeks of daily use in 50 participants with mature skin. Further research in the International Journal of Cosmetic Science (2021) reports that protective film-forming ingredients reduced TEWL by 22 % over 24 hours after application compared with a control.
