Polyhydroxy acids work by gently removing dead skin cells, promoting cell turnover, and improving skin texture and tone. Additionally, PHAs possess humectant properties, attracting and retaining moisture in the skin, resulting in enhanced hydration and a plump, youthful appearance. Moreover, their larger molecular size allows for slower penetration into the skin, reducing the likelihood of irritation. In conclusion, incorporating polyhydroxy acids into skincare routines can provide gentle exfoliation, hydration, and overall skin rejuvenation, making them a valuable addition to any skincare regimen.
