If AHAs were seniors in skincare school, PHAs would be the freshmen. These new actives on the block are essentially considered to be the second generation of AHAs – the main difference being that they are gentler and less irritating on the skin. They brighten, smooth, and hydrate, too, so this means that you can say goodbye to dry skin post-exfoliation! Pro tip: If you have sensitive skin and have been unsure about trying chemical exfoliation, give PHAs a try. Since they also give your skin a boost of hydration, you can be sure that you’ll end up with soft and soothed skin after.
