A naturally occurring chemical called salicylic acid is extracted from the willow tree's bark. Salicylic acid is keratolytic, which means that it dissolves the skin's outer layer, facilitating the removal of dead skin cells and promoting cellular turnover, according to Dr. Shuting Hu. It belongs to a group of beta-hydroxy acids, or BHAs, and is well known for its ability to aid in surface exfoliation.
"When it comes to skincare, you'll either run into Alpha Hydroxy Acids (AHAs) or Beta Hydroxy Acids (BHAs)," stated Dr. Hu. Salicylic acid and other BHAs are more soluble in oil, whereas AHAs are more soluble in water. Compared to water-soluble BHAs, BHAs more readily permeate the lipid layers of skin cells and reach a deeper level of skin penetration.
The Benefits of Salicylic Acid for Skin
Dr Hu stated that salicylic acid, being an oil-soluble compound, possesses the ability to penetrate deeply into skin cells, effectively eliminating impurities that obstruct the pores and contribute to the formation of whiteheads, blackheads, and pimples.
This characteristic renders it a potent agent in the fight against breakouts.
He further elaborated, "A crucial aspect of the cleansing process involves the removal of excess sebum from the pores, which aids in diminishing oiliness and addressing acne.
Dr Hu noted that the acidic component of the molecule can disintegrate and loosen the desmosomes—proteins that bind cells together—thereby facilitating the exfoliation and cleansing of impurities that congest the pores.
In addition to its role in exfoliating dead skin cells and clearing blocked pores, salicylic acid also offers the advantage of minimizing the appearance of pores and alleviating inflammation.
Intended Audience
Salicylic acid is suitable for all skin types; however, Dr. Hu indicated that individuals with acne-prone and oily skin will derive the greatest advantages from this ingredient due to its anti-inflammatory properties, which aid in alleviating irritation, addressing acne issues, and preventing future breakouts.
For those with notably dry skin, it is advisable to steer clear of salicylic acid, as its oil-removing properties may exacerbate dryness.
