mandelic acid benefits uses side effects products & faqs

Mandelic acid is a very popular alpha hydroxy acid(AHA). It is found in the form of white crystalline solid and is highly soluble in water and organic solvents that are polar in nature. It is an organic compound, synthesized from an extract of bitter almonds by the process of hydrolysis. However, there are various other methods that can be used for the production of mandelic acid such as the heating of phenylglyoxal with alkalis.

Structure of Mandelic Acid:

The structure of mandelic acid is chiral i.e. the molecule when divided, forms a mirror image. The chemical formula of mandelic acid is C6H5CH(OH)CO2H with a molar mass of 152.15g·mol−1. It has a density of 1.30g/cm3.

Benefits and uses of Mandelic acid:

Skin Care:

  • It has a wide application in skincare industry and is majorly used as a constituent of chemical skin peels just like other alpha hydroxy acids (AHAs). Mandalic acid peels are generally the best for the person who is using the chemical facial peels for the first time.
  • The molecules of mandelic acid are generally bigger in size as compared to glycolic acid or lactic acid molecules and feel less irritating to the skin.

Mandelic Acid Vs. Glycolic Acid:

Glycolic Acid is a widely used alpha hydroxy acid in the skin care industry for the production of anti-aging and skin care products but the thing that makes mandelic acid different from glycolic acid is the size of the molecule.
Glycolic acids have bigger molecules which makes it easy for the skin to accept it and decreases the irritation caused by the penetration of molecular particles.


Side-effects and Precautions:

Utilization of mandelic acids doesn’t cause major side effects to skin but mandelic acid being an alpha hydroxy acid can make your skin highly sensitive to sunlight.
