How long does it take for post inflammatory erythema (PIE) to fade?

Thanks for the detailed summary. There’s no problem at all with seeing a GP to treat your acne – the treatment algorithm for acne is pretty standard. My pet peeve is only with clinics who overcharge based on having some sort of special super secret ingredient “miracle acne creams”, because the reality is that all effective topical creams contain well-known ingredients, and packaging it under their own brand shouldn’t give them the right to charge more, or “lock-in” patients to only using their creams.

Sorry to hear about your persistent acne. Don't worry, there are effective solutions for your acne! Differin contains Adapalene, which is a third-generation topical retinoid. Both Differin and Adapalene work by reducing comedones and oil production. They also have exfoliating effects. This helps to improve acne. Differin versus Tretinoin Based on research, both Differin and Tretinoin are effective for mild to moderate acne. However, Differin (Adapalene) has less skin irritation. If cost is not a concern, Differin is a better option, because it causes less skin irritation.
