Provitamin
Provitamin — a precursor compound that the body or skin converts into an active vitamin. In skincare, provitamins are used because they can be more stable in formulation and then transform into their functional vitamin form once applied or absorbed.

- Provitamins are often chosen for greater formulation stability compared with their active vitamin counterparts.
- Conversion to the active vitamin can depend on skin enzymes and metabolic processes.
- Beta-carotene is a provitamin A compound that the body can convert into retinol.
