Oil-absorbing agents
Oil-absorbing agents are ingredients that soak up excess sebum to help control shine and keep skin looking fresh and matte. They are commonly found in primers, mattifying moisturisers, foundations and blotting powders, making them a favourite for anyone prone to oiliness or midday shine.
How it works in skincare
In cosmetics and skincare, oil-absorbing agents work by using their porous structure or high surface area to physically adsorb excess sebum without stripping the skin. Popular examples include kaolin, bentonite, silica, and specialised starches; they are incorporated into formulations to deliver a long-lasting matte finish, improve wear time of make-up, and prevent that greasy feel throughout the day.

Where it comes from
Many oil-absorbing agents are naturally derived minerals such as kaolin (china clay) and bentonite, which are formed from decomposed volcanic ash and feldspar. Others, such as rice starch or corn starch, come from plant seeds and grains.
