I hope you can help me?
I'm 27 and have recently developed acne for the first time in my life. Having had floorless skin before now I am finding it an emotional and expensive battle. I came off of the pill injection not so long ago and feel that this is a side affect (with many others). I have been to see my GP and have been given medication but found that the products only burn my skin. at the moment my skin is so dry but more importantly scared from the anger of the spots. Please could you help? what should I use to try and clear the scars?
