When should I use the retin a after using neoprosone gel? Basically how can I combine...

Are you sure you want to use neoprosone gel? It has so many bad side effects since it's a steroid. It would just be safer to use RA, HQ 4% and another cream that has HQ in it and mix them all together with equal amounts. But you CAN use RA and neoprosone gel together with equal amounts.

Even a high dosage of hq i.e. hq 10% is safer than neoprosone it is very dangerous and contains mercury

OMG!, everything but''GELS'',, CAREFUL DEAR
