Salicylic acid is worth your time if you're trying to improve skin texture. It helps to shed dead cells so skin appears invigorated and renewed. This acid is most well known for fighting acne and breakouts though. It clears out pore-clogging substances and excess oil to ward off whiteheads, blackheads, pimples, and even acne.
Salicylic acid is extracted from willow tree bark. It's a beta hydroxy acid (BHA) so it acts as a chemical exfoliant. Salicylic acid is able to cut through oil unlike many other acids, which is why it's particularly popular for fighting breakouts and acne.
Those with oily skin or acne can see the biggest benefits. Use salicylic acid in moderation at first to see how you tolerate it. It's best combined with a soothing moisturiser to calm any irritation.
