hi John,thanks for your query..
What you have looks like post inflammatory hyper pigmentation( due to previous scars).You can apply Hydroquinone
2% containing creams on these spots to fade them.
Only way to prevent them from happening is to prevent the folliculitis
from happening,which unfortunately is very recurrent.If unable to tolerate oral antibiotics
,you must use topical ointments/creams go MUPIROCIN/Fusidic acid
for 14 days each months.Meaning ,if you start using the cream from today, use it twice daily on the affected areas for 2 weeks.then give a gap of 2 weeks and reapply again.This way do it for 3-4 months till it completely subsides.You would see the scars fade out faster as well!
Whilt bathing ,use medicated soap containing Triclosan
eg Soapex .
