Thanks for writing to us.
It seems you are doing self medication
for your acne which is not at all advisable. Doxycycline is used in acne but is not indicated in all types of acne.
i will advise you to meet a dermatologist
near by for proper consultation.
In the meanwhile
use a salicylic acid
based face wash- neutrogena or saslic or saliac or spongysal
in day and adapalene
gel in night time.
get your blackheads removed
avoid facials massages and oily products over face
safi might be a blood purifier but acne has nothing to do with blood impurity! simply using safi wont help.
