Salicylic Acid for Acne: How to Use It Without Irritation
Salicylic acid is a beta hydroxy acid (BHA). It is oil-soluble, which means it can work inside pores. This makes it popular for blackheads, oily skin and acne-prone skin.
How it helps
Salicylic acid gently loosens dead skin cells and helps keep pores clear. It works best as part of a routine rather than as a one-off treatment.
Where to start
- Cleanser: a salicylic acid cleanser is a low-pressure first step.
- Leave-on treatment: a product such as the Paula's Choice 2% BHA Liquid Exfoliant is more concentrated, so use it less often at first.
How to introduce it
- Use it three nights a week for two weeks.
- Increase only if your skin feels comfortable.
- Skip it on nights you use other strong actives.
- Moisturise and use sunscreen in the morning.
Signs you need to pause
- Burning or stinging that does not settle
- Redness, peeling or a tight feeling
- New breakouts that look like irritation
Salicylic acid is generally not recommended in large amounts during pregnancy. Ask your doctor before using it if you are pregnant or breastfeeding.
