Ingredients higher up in an ingredient list are typically present in a larger amount. Salicylic Acid (also known as beta hydroxy acid or BHA) is a well-known ingredient for treating skin that struggles with acne and clogged pores. It exfoliates both the skin's surface and deep within the pores to help clear out buildup, control oil, and reduce inflammation. Unlike AHAs (alpha hydroxy acids), salicylic acid is oil-soluble. This allows it to penetrate into pores which makes it especially effective for treating blackheads and preventing future breakouts. Salicylic acid is also known for its soothing properties. It has a similar structure to aspirin and can calm inflamed or irritated skin, making it a good option for acne-prone skin that is also sensitive. Concentrations of 0.5-2% are recognized by the U.S. FDA as an over-the-counter topical acne product. It can cause irritation and/or dryness if one's skin already has a compromised moisture barrier, so it's best to focus on repairing that before introducing this ingredient into your routine. While salicylic acid does not increase sun sensitivity, it’s still important to wear sunscreen daily to protect your skin.

Water most often acts as a solvent - this means that it helps dissolve other ingredients into the formulation. You'll also recognize water as that liquid we all need to stay alive. If you see this, drink a glass of water. Remember to stay hydrated!
