We’re sure that if you’ve read anything skincare-related in the past year, you’d be familiar with ‘salicylic acid’. In case you need a quick refresher, here’s one – this beta hydroxy acid is an oily and combo-skin favourite for many reasons, the main one being its power to cut through oil, unlike AHAs. Along with exfoliating your skin, this acid cleans out excess sebum, softens clogged pores, and removes blackheads and whiteheads, too. Plus, it prevents future breakouts, too – now this is one ingredient that definitely lives up to its reputation. Pro tip: If you have dry or sensitive skin and are looking for an exfoliant, skip this one – it is known to be extremely drying and won’t be the best pick for you. Instead, try a PHA.
