What is salicylic acid?1,2,3
- Salicylic acid is an oil-soluble BHA (beta-hydroxy acid). Often, these two terms are used interchangeably. It is commonly found in over-the-counter (OTC) skincare products at a range of 0.05% - 5% (up to 0.5% in Korean skincare). Commonly, it is obtained from the bark and leaves of the willow and wintergreen trees. Salax, meaning willow tree in Latin, is the origin of the name.
- When it comes to exfoliants, you have more than a few options to choose from depending on your skin type. I will describe how salicylic works after explaining how breakouts form: clogged pores are caused by bacteria, dust, debris, and sebum mixing together. As opposed to alpha-hydroxy acids (AHAs), which are water-soluble and ideal for surface exfoliation, salicylic is oil-soluble, so it is able to penetrate deep within your pores and exfoliate them to remove blockages.
- It works by increasing the amount of moisture in the skin and removing the substance that binds the skin cells together, making it easier for them to shed. So now you can see why the ingredient has been a favorite for oily, acne-prone skin for so long, then?
- While salicylic acid is most commonly known as a mild acne spot treatment, the ingredient can also be found in a variety of other products, such as cleansers, toners, serums, and peels, all of which can benefit the skin. Each vehicle uses salicylic acid in its own unique way, and is designed to target specific skin issues in specific people. The caveat is that some cleansers, peels, and toners can be overly harsh and should be avoided.
Benefits of Salicylic Acid4,5
- Exfoliates dead skin: Salicylic acid is a keratolytic, encouraging cell turnover and sloughing off dead skin cells. This can improve dullness, blemishes and texture of the skin.
- Softens the contents of clogged pores: the oil-soluble ingredient penetrates the pores and loosens the "glue" that sticks the skin cells together, which leads to whiteheads, blackheads, and small red pimples.
- Removes excess oil: Because salicylic acid is oil-soluble, it can penetrate beneath the skin's surface to remove excess sebum from the pores and reduce oil production. Furthermore, the pores may also appear smaller as a result of this.
- Prevents whiteheads and blackheads: Salicylic acid will not only treat existing breakouts, but it will also prevent them from returning to the surface of your skin because it targets whiteheads and blackheads directly.
- Reduces inflammation: Salicylic acid is part of the same chemical family as aspirin (salicylates). In addition to its anti-inflammatory properties, salicylic acid helps reduce irritation and redness associated with breakouts.
