acne
"Was prescribed Epiduo by my doctor after being diagnosed with PCOS (spots/acne is often a common side effect of this) - anyway, first two weeks of using it my skin was BAD. Cystic acne, redness, itchy, painful skin to touch the whole nine yards. Then it just stopped being as painful and the spots really REALLY cleared up. 

I have smooth cheeks now, with the odd one spot just creeping up hormonally as expected. 

However, do not use any other harsh spot clearing product (or have a skin specific facial) on the face as I guarantee it'll be painful and red all day (speaking from experience!!!)"
