Oil-absorbing, smoothing, firming
One of nature's fundamental building blocks, Silica is an important part of collagen, which is essential for elasticity and youthfulness. Silica is also fundamental in the manufacturing process of antibodies and antigens for the immune system.
Commonly used in cosmetic face powders, silica imparts a smooth texture to the skin and allows the powder to blend evenly over the face as well as enhancing the aesthetic and functional quality of the product.
Silica gel's high specific surface area allows it to adsorb water readily, making it useful as a desiccant (drying agent) which makes it an important part of cosmetics designed to mattify oilier skin types. As well as water it can help absorb toxins on the skin, making the environment less favourable to blemishes and breakouts.
When used on skin silica has a cooling effect, keeping inflammation of the skin down.
