I recently had a very bad cystic pimple on my nose with left a small boxcar scar with a icepick scar in the center. I was upset because its in the center of my face and know that this could be permanent. I went to the dermatologist and he gave me prescription strength retinal, which I apply at night. Its quite strong so I alternate after a few days with glycolic acid (20%). In the morning I apply topical vitamin C and sunscreen. To my surprise and relief, the scar has improved dramatically in two weeks. Please note these products are very aggressive and you need to be extremely careful when going in the sun. Its not for everyone, especially if you have sensitive skin. But I did want to share because it is possible to greatly improve scarring with some patience and diligence, and without the cost of pricey laser procedures. God bless all.
