What Are AHAs?
There’s plenty of acids out there in skincare, but which one is right for you? Some ingredients can share similarities and makes it hard to decide which one to try! That’s why we’re comparing three to help make it easier for you: Mandelic acid, lactic acid and glycolic acid. Let’s dive into our ingredient comparison with these three AHAs!
Mandelic acid, lactic acid and glycolic acid are all AHAs. Meaning they’re chemical exfoliants that all address similar skin concerns such as:
- Uneven skin tone
- Dehydrated skin
- Aging skin and more
All three are also hydrophilic, meaning they attract and bind water to your skin. Helping with hydration and improved skin texture. One of the most important things to keep in mind is to ALWAYS wear SPF if you’re wearing any of these ingredients! All these ingredients have great shared properties, but let’s see how they compare.
Ingredient Comparison: AHAs
Lactic acid stimulates ceramide production which can strengthen and protect your skin barrier. It’s also great for fine lines and wrinkles. If you’re choosing between glycolic and lactic acid, lactic is better for sensitive and dryer skin types. But it can still be irritating since it does go deeper than mandelic acid, so take caution when using lactic acid. If you need a less irritating AHA, switch to mandelic.
Mandelic acids can be helpful for those with oily and acne-prone skin since it has antibacterial properties! It’s also great for all forms of hyperpigmentation including post-inflammatory.
Glycolic acid is better suited for those with oily and combination skin since it can go deep and penetrate deeper. But with this comes a higher probability of irritation. We recommend not starting with glycolic acid as your first acid, rather glycolic is better suited for those with more experience with acid ingredients and therefore less sensitive.
