Meet mandelic acid, your skin’s new best friend. As a member of the alpha hydroxy acid (AHA) family, it’s a natural gem derived from bitter almonds.
What makes it special is its large molecular structure, which ensures gentle exfoliation and thus makes it perfect for all skin types, even sensitive skin. (1)(2)
While there are not many side effects associated with this ingredient, being an exfoliating agent, it does have the potential to make your skin more susceptible to sun damage when used without sunblock.
Even though mandelic acid is a gentler exfoliating ingredient than some other skin acids, like any exfoliant, it can make your skin more sensitive to the sun and increase your skin’s vulnerability to UV rays.
Continue reading to look into this ingredient and the sun sensitivity it causes in more detail.
Mandelic Acidand Increased Sun Sensitivity
Mandelic acid, a type of alpha hydroxy acid (AHA), is great for rejuvenating the skin by promoting cell renewal and reducing wrinkles. (3)
However, the problem is that AHAs can make your skin more sensitive to the sun. Researchers explain that using AHAs, like mandelic acid, along with sun exposure can lead to some skin damage. (4)
Research suggests that the increased sun sensitivity with AHAs is linked to the speeding up of the skin cell turnover process. Although it is important for antiaging actions, it also means your skin might not handle the UV rays as well.
So, while some studies deem AHAs great ingredients for preventing and managing premature aging caused by sun exposure, the key is finding the right balance as too much of AHAs can cause more sun damage. (4)
Therefore, if you’re using any chemical peels or exfoliators that contain AHAs, make sure you do not use a lot of them.
Also, use a good-quality and broad-spectrum sunblock after using such ingredients, especially if you live in a sunny place and can’t avoid the sun completely. (5)(6)
What Are the Benefits of Using Mandelic Acid on Your Skin?
Here is why you should use mandelic acid in your skincare routine.
- Clears up acne: Mandelic acid is great for clearing up acne by opening up clogged pores, making your skin appear much nicer. According to research, 45% mandelic acid was successful in treating mild to moderate cases of acne. (3)(7)
- Makes skin look youthful: Mandelic acid also reduces signs of aging such as wrinkles and fine lines by increasing hyaluronic acid content in the skin. A study showed that this ingredient was successful in making the skin appear younger at around 2 months. (8)(9)
- Reduces skin inflammation: Mandelic acid calms redness and irritation of the skin and is a much better ingredient compared to other AHAs in terms of lesser inflammatory side effects. This also makes it perfect for sensitive skin types. (10)(11)
- Helps treat rosacea: Mandelic acid is an excellent exfoliating agent, which means it will help your skin manage symptoms of rosacea. (11)
