Hyaluronic acid, ceramides, niacinamide and SPF.

PHA stands for polyhydroxy acids. They have larger molecules than AHAs and therefore work more slowly and more superficially.
What is it used for?
It is used in formulations for gentle exfoliation and a hydrated skin feel.

Even though PHA is gentle, it should not be layered with other acids or retinol on the same evening.
Good to know
