Hectorite
Hectorite is a naturally occurring mineral clay used in UK skincare and cosmetics as a gentle thickener, stabiliser and mattifying agent. It helps products achieve a smooth, luxurious texture while absorbing excess oil without stripping the skin.
How it works in skincare
In cosmetics and skincare, hectorite works by swelling in water to form a gel-like network that stabilises emulsions, suspends pigments and gives creams and lotions their silky, spreadable consistency. It is prized for its ability to mattify the skin by absorbing sebum and for creating a soft-focus effect that blurs the look of fine lines and pores, making it a popular ingredient in primers, foundations, masks and oil-control moisturisers.
