Hello troubled
There are several effective and proven methods of dealing with acne.
- Topical antibiotic gel
- Topical retinoid
- Chemical peel (salicyclic acid 20% to 30%)
- Oral medications (COCP/ Spironolactone/ Isotretinoin)
For stubborn cases, you can start with a combination treatment initially and slowly wean off the oral medications. Every treatment has its own pros and cons so speak to a doctor to find out what is the best approach for you. Do ensure adequate sun protection to reduce risk of PIH. Hope this helps.
Regards
