Hi guys,

I'm still struggling with my PIH mainly and some scarring that i have left over. I visited a derm 2 months ago and have been using 0.025% tretinoin cream since then. Although i have seen slight improvement, i'm not sure if it's just the effect or time or the cream. I am wondering if i should increase the strength of the tretinoin cream to 0.05% or to stick with 0.025%.

Will increasing the strength increase the rate/effectiveness of the cream in removing my PIH? Also, how long can i expect to see my red marks disappear with tretinoin cream? I've read that it takes about 6 months for it to really work.

Thanks!
