Mandelic acid, a lesser-known member of the alpha hydroxy acid (AHA) family, has been steadily gaining recognition for its gentle yet effective properties. Derived from bitter almonds, this versatile acid is often used in skincare routines as a chemical exfoliant. Its unique properties make it an excellent choice for those with sensitive skin or anyone seeking an alternative to harsher exfoliants like glycolic acid.
In this article, we’ll explore what sets mandelic acid apart, its benefits, and how it can help address common skin concerns.
What Is Mandelic Acid?
Mandelic acid is a type of AHA, a group of water-soluble compounds known for their exfoliating properties. What makes mandelic acid unique is its molecular size, which is about twice that of glycolic acid. This larger size slows its absorption into the skin, making it less likely to cause irritation.
Because of its gentler nature, mandelic acid is a great option for people with sensitive skin, rosacea, or those who struggle to tolerate stronger acids.
How Mandelic Acid Works
Like other AHAs, mandelic acid works by breaking down the bonds that hold old or dead skin cells on the skin’s surface. This process:
Exfoliates gently: Removes the outermost layer of dead skin to reveal smoother, fresher skin underneath.
Improves skin texture: Encourages the growth of new skin cells, helping to reduce the appearance of fine lines and wrinkles.
Unclogs pores: Dissolves blackheads and comedones while controlling sebum production.
Fights acne: Its antibacterial properties help eliminate acne-causing bacteria, reduce inflammation, and calm redness, making it effective against cystic acne.
The Science Behind Mandelic Acid
A 2019 study comparing 30% salicylic acid peels and 45% mandelic acid peels found both were equally effective in treating mild to moderate acne. However, mandelic acid was safer, more tolerable, and less likely to cause side effects. The study also highlighted its effectiveness in reducing inflammatory lesions.
Interestingly, higher-strength peels (30% or more) of mandelic acid have shown potential to increase sebum production. While this may not be ideal for oily skin, it’s beneficial for those with dry skin or discoloration issues, offering hydration alongside exfoliation.
Mandelic Acid and Hyperpigmentation
When it comes to fading hyperpigmentation, such as post-acne marks, melasma, or sunspots, mandelic acid appears to have a slight edge over other AHAs. It’s well-tolerated by all skin tones and has shown significant promise in addressing uneven skin tone.
Key Advantages of Mandelic Acid
Gentle on Sensitive Skin: Its slow absorption makes it ideal for people who can’t tolerate stronger acids.
Safe for All Skin Tones: Mandelic acid is effective across various skin tones and less likely to cause irritation or post-inflammatory hyperpigmentation.
Dual Benefits: Works as both a water-loving and oil-loving compound, offering multi-level benefits to firm, smooth, and hydrate the skin.
Light-Sensitive Properties: Unlike glycolic acid, mandelic acid is less likely to make your skin sun-sensitive, though it still requires sunscreen use.
Final Thoughts
Whether you’re dealing with acne, hyperpigmentation, fine lines, or uneven skin texture, mandelic acid is a gentle yet powerful tool to add to your skincare arsenal. Its unique properties make it an excellent choice for those with sensitive skin or anyone looking for a well-tolerated exfoliant.
