What it is
Salicylic Acid (Beta Hydroxy Acid/BHA or o-hydroxybenzoate) can be obtained from the bark of the willow tree or can be prepared synthetically.
What it does
Salicylic acid is a great exfoliant especially for people with acne-prone skin. Its has the ability to penetrate the pore. It can therefore exfoliate within the pore as well as the surface of the skin. This reduces blackheads, blemishes and whiteheads. Salicylic acid also has anti-bacterial and anti-inflammatory properties, which is another reason why it is good at treating breakouts.
Salicylic acid breaks down keratin, a protein that forms part of the skin structure. This causes shedding of skin cells, removing warts, calluses, verrucas and improving cell turnover. For this reason, it is also used as an anti-dandruff agent.
It also reduces oiliness, skin discoloration and appearance of fine lines and wrinkles. It improves collagen production, skin thickness and barrier functions.
When used in combination with other treatments, it allows their ingredients to penetrate the skin more easily and effectively.
It can also be used as a preservative.
Side effects
Salicylic acid causes sun sensitivity so you should always apply a broad-spectrum sunscreen when using this ingredient.
It can also cause skin irritation, stinging, burning, flushing, reddening of skin. It can also be drying.
Salicylic acid shouldn’t be used by zinc-deficient individuals, as it can cause transient hearing loss, and by salicylate sensitive people. Pregnant women should consult their doctor before using products containing this ingredient.
