Differin vs Paula's Choice BHA: Which One for Closed Comedones?

How they work

• Paula's Choice 2% BHA ($34): salicylic acid dissolves the plug inside the pore. Fast – smoother texture in 2–3 weeks.
• Differin 0.1% ($27): adapalene normalises how the follicle sheds cells so plugs don't form. Slower – 8–12 weeks – but prevents recurrence.

Which first?

Start with BHA for quick texture improvement, then add Differin after two weeks for the long game. Together they are the most effective OTC pair for closed comedones.

Avoiding irritation

• Alternate nights for the first two weeks
• Pea-sized amount of Differin for the whole face, applied to completely dry skin
• Always follow with a barrier balm (Cicaplast B5) and SPF next morning
• Expect a mild purge in weeks 2–4; stop only if skin burns or peels badly
