HI Elainecorr,
Great to hear your client is on the full home prescription. Just one thing, you said he uses Alkaline wash at home, do you mean 'acne wash'?
Another great product he must use would be the direct delivery vitamin c serum. This helps the skin to heal, improve the capillary network as well as brightening.
Please rest assure the 5%BP will still do its job. He needs to understand the skin is under attack at the moment, and this is why you have prescribe him BP in the first place. Once his skin heals and strengthens, this problem should not come back, or not come back as severe.
Good luck and please let me know if I can assist you any further~
Regards,
Amy
