Hi there!
This medication is very strong, it is known to work, but it has very adverse side effects. Check the side effects first before using it.
Have you tried LED mask? It is mask which emits LED light with healing properties for skin. I use it every day. I do 15 mins in the morning and 15 mins in the evening. It helped a lot. You need to check which coloured light you need. I use purple light for acne, it is better to buy the one that has the whole spectrum of lights rather than only one, so you can use first purple light and later lets say red light to heal the scars.
