If you’ve been suffering from ‘maskne’ – spots caused by face coverings – or any other types of pimples, salicylic acid could be the answer to your prayers. Here’s everything you need to know about salicylic acid…
What is salicylic acid?
“Salicylic acid is a beta hydroxy acid (BHA), known for its peeling and exfoliating effects, that help promote elimination of dead skin,” says Nassim Hamek, product manager at Typology.
Similar to alpha hydroxy acids (AHAs), salicylic has one major advantage over AHAs, says Perricone MD international training manager Dan Perry: “Most acids such as glycolic acid, work on the upper layers of the skin to exfoliate, but are unable to target problems underneath the skin. Salicylic acid can permeate the upper layers of the dead skin to dissolve excess oil, and especially hardened oil such as blackheads and whiteheads.”
How does it help with acne?
“Excess oil can harbour additional blemish-causing bacteria which contributes to acne,” says Perry, which is why reducing oil under the skin can help prevent spots from forming. “The other interesting point about salicylic acid is its natural anti-bacterial and anti-inflammatory properties can help reduce bacteria and swelling of existing acne.”
How should salicylic acid be used – and how often?
“You can find salicylic acid in many different products, spot treatments, serums, lotions, moisturisers. However, you have to be careful using this molecule,” says Hamek, as it can cause irritation, which is why European regulations set a limit of 2% concentration in cosmetic products.
“Even diluted to 2% the molecule is very effective. With a targeted spot treatment serum you can apply one drop on the spot each night and it can reduce significantly within days,” adds Hamek. For daily use, concentrations of 1% or lower are more suitable.
“For people with generally problematic skin, I would recommend starting with a cleanser with salicylic acid since it has been shown to work extremely well even in ‘wash off’ products,” Perry says. “Treatment masks with salicylic acid should not be applied more than twice per week.”
Are there any risks associated with using salicylic acid?
“If you have sensitive skin and would like to use products with salicylic acid, we recommend testing the product on your arm and waiting for 48 hours to see if a reaction appears,” says Hamek, as it can cause irritation for some skin types.
Pregnant women should also be wary, says Perry: “It is questionable whether you should use salicylic acid while pregnant, so do check with your doctor.”
