Longtime BP user here, 10+ years. I wanted to try something different so I got a Skinoren prescription from Boots ( UK) online. Used it for about 4-5 weeks. I probably went little balls deep on it ( used too much from the off) but it made my skin so incredibly itchy. I also got a bit of a chemical burn on my cheek near to my nose. It would take about 30-60 minutes before my skin would feel normal. I also couldn't find any info about using a moisturizer in combination with it.... lots of conflicting info everywhere. Didn't really help with acne just irritated my skin. I may give it another go ( using less of it next time) but it's not suitable for long-term use so any benefits will be < 9 months as its recommended to stop use after a year. I've also used differin which gave me a similar experience.
