If you’re interested in skincare beyond cleansing and moisturising, you’ve probably heard the word acid being thrown around. From glycolic to salicylic to hyaluronic, they may sound intimidating, but they hold the key to better skin. So what do they all mean and which one should you be using? Read on to get to know the most common acids used in skincare and what they can do for you.

Glycolic acid
No longer confined to expensive salon treatments, a small percentage of this AHA (alpha-hydroxy acid) can be found in many of the most effective toners and peels. It gets rid of dead skin cells to reveal fresh, new ones and leave you looking radiant. In the long-term it will also reduce the appearance of lines and wrinkles. Introduce this into your routine gradually, especially if you have sensitive skin, and expect it to tingle on application.

Hyaluronic acid
Most commonly found in serums and moisturisers, this acid is like a magnet for moisture. It will boost your skin's hydration levels and help to retain them too. Add it into your skincare routine for plumper, softer, younger-looking skin.

Salicylic acid
Products containing this BHA (beta-hydroxy acid) deep clean your pores and can even pass through sebum which makes it ideal for anyone with oily, acne-prone skin. It also exfoliates the skin's surface to remove breakout-inducing bacteria and it's an anti-inflammatory too, helping to reduce redness.
