Mandelic acid is an almond extract that is gaining popularity as an alpha hydroxyl acid suitable for all skin types and complexions, giving it a unique advantage. This new skin care sensation helps bring clarity and balance while causing virtually no irritation.

Mandelic acid is also recommended as a pre and post laser treatment, reducing the amount and length of irritation caused by laser resurfacing.
