#LetsGetActive: It’s time for your next assignment. Get glowing skin with the acid that’s topping our lists at the moment – beta hydroxy acid. This oil-soluble acid ranks as one of our favourite skincare ingredients thanks to its ability to penetrate the skin and unclog pores. Pick one up if you’ve got oily skin that is prone to breakouts, and pair it with an alpha hydroxy acid, tea tree oil, or charcoal-based product for best results. Pro tip: Apply sunscreen regularly when using BHAs as they can increase your skin’s sun sensitivity.
