i used to have acne bumps on my chin but they have been gone for a while now. now all i have is a lot of redness there where the bumps used to be. i wash my face 2 times a day and i use differin gel at night but i still can not get the redness to go away. do you have any suggestions that might help? thanks for your help i could really use it
