Salicylic Acid (BHA) – Benefits, Side Effects & Uses

Reviewed by Thank Me Now Skincare Editor · Last updated: September 2025

Salicylic Acid is one of the most popular beta hydroxy acids (BHAs) in skincare. Known for its ability to unclog pores and calm inflammation, it's a favourite among dermatologists for treating blackheads, whiteheads, and breakouts.

What is Salicylic Acid?

Salicylic acid is an oil-soluble exfoliant that penetrates deep into pores, breaking down the mix of dead skin cells and sebum that cause congestion. It has anti-inflammatory properties, making it particularly helpful for acne-prone and oily skin types.

Who Should Avoid It?

Very dry or sensitised skin (may worsen dryness)

Pregnant individuals should consult their doctor before use

How to Use It in a Routine

Use 2–4x/week after cleansing as a toner, serum, or treatment
