Hydroxyapatite

What Hydroxyapatite is & what it does

Hydroxyapatite is a calcium phosphate mineral and the main mineral component of natural tooth and bone, produced for cosmetics in synthetic or processed forms. In skincare and sunscreen formulas it can act as an absorbent, bulking, or opacifying powder and is sometimes used to give a smoother texture or soft finish. A notable property is its fine mineral particle structure, which lets it work as a dry, mattifying-type filler.

Is Hydroxyapatite safe?

Hydroxyapatite is a calcium phosphate mineral and the same family of mineral found naturally in teeth and bone, and it is generally regarded as safe at the levels used in cosmetics. In skincare it is typically used as an inert mineral powder rather than an active that penetrates skin. As with any ingredient, very sensitive skin can patch test first.

What does Hydroxyapatite do in skincare?

Hydroxyapatite is a calcium phosphate mineral used in skincare and sunscreen formulas as an absorbent, bulking, or opacifying powder. Its fine mineral particles can help give a smoother texture or a soft, mattifying-type finish. It is usually a texture-supporting ingredient rather than a primary active.

Is Hydroxyapatite natural or synthetic?

Hydroxyapatite occurs naturally as the main mineral in tooth and bone, but the cosmetic grade is usually synthetic or processed for purity and consistency. So it is best described as a naturally occurring mineral that is typically produced in a controlled form for use in formulas. Its chemical identity is the same regardless of source.
