Treatments for Nodular Acne

Hey guys, I just want to write this post to ask you if you know an effective treatment for nodular acne? My brother really needs it now. I just don't want to see his face with so many acne. It's kinda irritating and disturbing already.

I already read a lot of reviews on these kind of products but I want you guys to tell me the product that you have tried and worked for you. I hope you can help me. Thank you so much.

Just drop it on my comment's box okay? Have a great day!
