Mandelic Acid

Mandelic acid is a type of alpha hydroxy acid (AHA). There’s some research showing mandelic acid is an effective exfoliant, although it’s not as effective as glycolic acid due to its larger size (it’s twice as big as glycolic acid) and slower penetration into skin; however, these traits can also make mandelic acid more tolerable for those with sensitive skin. Unlike glycolic acid, mandelic acid is light-sensitive and must be packaged in an opaque container to remain effective. It may be synthetic or derived from almonds. Like other AHAs, mandelic acid is most effective in leave-on products that are within a 3-4 pH range. A couple studies have shown that mandelic acid and salicylic acid worked well together in a higher-strength peel for use on darker skin tones struggling with discolourations, including post-blemish marks. However, what we don’t know is how well mandelic acid would’ve worked on its own - it’s possible the results were more from salicylic acid than the combination of the two acids. Other research has shown mandelic acid can increase sebum (oil) production, which isn’t great for oily skin but would be a benefit for dry skin.
