Yet another skincare acid, mandelic acid is a standout because of its low potential for irritation. It has lots of benefits without the drawback of irritation often seen with other acids, so is a great choice for those with sensitive skin.
What is mandelic acid, and what does it do?
Mandelic acid is an alpha hydroxy acid. Due to its large molecular size, it’s absorbed more slowly so is less irritating than other alpha hydroxy acids such as glycolic acid and lactic acid, but is also less powerful. It’s a gentle chemical exfoliant, lifting off dry, dead skin cells from the surface of the skin. It can also stimulate collagen production.
Why should I use it?
Mandelic acid can help brighten dull skin, and fade uneven skin tone and hyperpigmentation. It can also improve the appearance of fine lines and wrinkles, and help manage acne. It’s a great choice if you have sensitive skin, as it’s less irritating than other alpha hydroxy acids.
How should I use it?
Apply mandelic acid at night followed by moisturiser, one to three times per week. If you have sensitive skin, start just once weekly to a test patch of skin first. It can also be used in a higher concentration less frequently, as a chemical peel.
Does it have any drawbacks?
Despite being less likely to cause irritation than other alpha hydroxy acids, there’s still the potential for irritation, especially if you have extremely sensitive skin. Mandelic acid can increase sun sensitivity, so always use sunscreen during the day. It’s light-sensitive, so must be kept in the dark (ideally in an opaque or dark glass container) to remain effective.
