Which skin conditions is BHA used to treat?
What is a beta hydroxy acid (BHA)?
BHA is used to treat a variety of skin conditions. It is an organic acid derived from willow bark. In the skincare industry it is known as a chemical exfoliant. The ph level of this acid is typically between a ph of 3-5.
BHA is considered to be a fat soluble solution. In other words it dissolves in fats. As a result, it can break through the lipid layer which is the oil layer of the skin. For that reason, it is recommended for oily and acne-prone skin types.
However, that is not the only use for BHA on the skin! It is also a recommended treatment for sensitive skin types because it has a lower risk of irritation versus other types of acids.
How does BHA interact with the skin?
BHA produces exfoliating benefits by dissolving the build-up at the surface of the skin which then balances the oiliness of the skin. It is also able to penetrate into the pores which then dissolves the build-up in clogged pores.
It treats conditions that involve scaling or overgrowth of skin, like milia.
BHA helps with milia because it has resurfacing properties. So, not only does it help remove excess oil on the skin, but it helps to exfoliate by removing the dead skin cells so it dissolves the binding glue or the lipids that hold the dead skin cells together so it reveals a fresh new layer of skin at the surface which then pushes impurities up to the surface such as milia and deep acne.
Anti-inflammatory properties
BHA also has anti-inflammatory functions which makes it a suitable treatment for inflamed acne and/or rosacea. Compared to other acids such as glycolic acid, salicylic acid has a more superficial affect on the skin by interacting mainly with the lipid layer.
In other words, it is not as irritating because it won’t penetrate as deep. However, it will promote exfoliation which in turn promotes cell growth. These new skin cells have been strengthened by that process and so the skin is improved overall.
Finally, BHA is also very good at treating Keratosis pilaris which a is a condition that affects the back of the arms and legs.
