Is mandelic acid effective in treating post inflammatory hyperpigmentation?

Mandelic acid is indeed recognized for its effectiveness in treating post-inflammatory hyperpigmentation. As an alpha hydroxy acid (AHA), it works by gently exfoliating the outer layers of the skin, which helps in promoting cell turnover. This exfoliation allows for the fading of dark spots and uneven skin tone that often follow acne lesions. Additionally, because mandelic acid has a larger molecular structure than other AHAs, it penetrates the skin more slowly and is less irritating, making it suitable for sensitive skin types.

Its ability to improve skin texture and promote the renewal of skin cells makes it a valuable option in addressing conditions like post-inflammatory hyperpigmentation. The gentle nature of mandelic acid reduces the risk of causing additional irritation or pigmentation, further enhancing its appeal in treating hyperpigmentation linked to prior inflammation.
