What is salicylic acid? Salicylic acid belongs to the class of hydroxy acids known as beta hydroxy acids (BHAs), a group of hydroxy acids known for their exfoliating properties. Like other hydroxy acids, it acts as a chemical exfoliant by breaking down the bonds that hold dead skin cells together, especially within clogged pores. This chemical exfoliation gently removes dead cells without the harsh abrasion caused by physical exfoliants such as scrubs or brushes, making it effective yet mild on the skin. How is salicylic acid different from other hydroxy acids? When most people talk about hydroxy acids, they’re actually referring to alpha hydroxy acids (AHAs) – there are many more varieties of AHAs (think glycolic, lactic, citric, malic, and so on) than BHAs. The key difference is that AHAs are water-soluble, while BHAs like salicylic acid are oil-soluble. This matters because the skin’s surface contains water, while deeper layers have oils (lipids). Water-soluble AHAs work near the skin’s surface, while oil-soluble BHAs can penetrate deeper into oily pores. Because salicylic acid dissolves in oil, it can reach deep inside clogged pores to break down dead skin cells causing blockages. Additionally, unlike AHAs, salicylic acid also kills P. acnes bacteria, a major factor in acne formation. Which ingredients work well with salicylic acid? AHAs and salicylic acid are perfect together. Combining the two targets multiple layers of skin, tackling surface issues as well as what lies beneath. Salicylic acid can increase skin dehydration or irritation (especially when you start using it), so products that also contain calming ingredients (such as Ceramides, Hyaluronic Acid, and Centella Asiatica Extract) are a wise, proactive measure. While salicylic acid doesn’t increase sun sensitivity as much as AHAs, daily use of SPF 30 or higher is still essential to keep your skin safe and healthy. Who should avoid using salicylic acid? If your skin is already dry, salicylic acid may not be the right solution for you. Those with very sensitive skin, rosacea, or eczema should consider alternative treatments before using salicylic acid. As with any new skincare ingredient, if you are pregnant or nursing, it’s best to consult your doctor before adding it to your routine. What are products that contain salicylic acid? a While the acids dive deep to unclog pores and refine skin texture, the advanced formulation with Liposomal Tri-Active System ensures your skin stays balanced and calm.
