You know that top student who’s also the all-star athlete, president of the debate club, and community service leader? In the world of acids, glycolic acid is practically their equivalent. This popular alpha hydroxy acid does more than just treat breakouts – it exfoliates your skin, stimulates collagen production, and fades away dark patches, too. While all of this sounds amazing, it’s important to remember that you need to start slow to reap the benefits. Start with lower concentrations of this acid and then build it up, and expect light stinging and redness until your skin gets used to it. Pro tip: Many claim that glycolic acid can get rid of acne scarring, but all it really does is just lighten any dark patches and soften the look of raised scars. It’s best to speak to your dermatologist about other treatments if this is your main skin concern.
