How to fit BHA into your routine
- 1Cleanse gently. Avoid rough cloths and abrasive scrubs, which can irritate skin and damage its moisture barrier, the outer layer that holds moisture in.
- 2Apply your leave on BHA as directed on the bottle. Keep salicylic acid away from your eyes, mouth and the inside of your nose, and do not apply it to irritated, infected or reddened skin.
- 3Apply moisturizer. Choose one that meets your skin's needs without duplicating exfoliating ingredients already in your routine.
- 4In the morning, finish with sunscreen of at least SPF 30. Use sunscreen every day, including days when you apply BHA only at night.
Should you use BHA morning or night?
General salicylic acid guidance allows use up to twice daily for many people, so BHA is not automatically an evening only ingredient. Your exact product's directions still set the frequency: do not increase applications just because another salicylic acid product allows more. More frequent use can mean more irritation, not a better routine. If your skin becomes dry or irritated, do not keep increasing use. Report symptoms that continue or bother you to a healthcare professional.234
Which moisturizer should go after BHA?
Choose a moisturizer for your skin's needs, and check whether it also contains exfoliating acids or retinol. A moisturizer can carry active ingredients too, despite having the least dramatic job title on the shelf. Aim for products that complement each other rather than doubling up on the same ingredients. Do not combine salicylic acid on the same area with topical retinoids, benzoyl peroxide or other medicated treatments unless your doctor directs you to.123
What should you expect from BHA?
Salicylic acid is a beta hydroxy acid, or BHA. It helps remove dead skin and clear oil from pores, making it useful for blackheads and whiteheads. Benefits take time and regular use; do not expect changing the layering order to produce an immediate result. There is no precise Paula's Choice results timetable to give here. Focus on following the product directions rather than adding applications to hurry things along.3
When should you get medical advice?
Get medical advice for moderate or severe irritation, burning, crusting or peeling, or unusually warm, reddened skin. Report signs of an allergic reaction, including hives or swelling of the face, lips, tongue or throat, promptly. If you are pregnant, trying to become pregnant or breastfeeding, discuss salicylic acid use with your healthcare professional before using it.24
