PCOS is a fairly common condition in Singapore that usually goes under-diagnosed.
You are right, it's advisable to have a more stable skin condition, before going for acne scar treatments (in particular, fractional lasers).
However certain acne scar treatments like subcision are safe to do, even during minor acne outbreaks.
I noticed you mentioned you are taking contraceptive pills. As such we should consider adding on Spironlactone (which has an anti-androgenic effect) that reduces oiliness.
In fact, spironolactone might be a better idea as a first-line for the PCOS-associated acne.
