It sounds like you’re describing post inflammatory hyper-pigmentation. There are some things you can start doing immediately: 1) Be sure that you are using a very good facial sunblock every single day, otherwise those marks are going to get darker and darker. 2) You need to start using a pigmentation inhibiting product for 2 reasons; 1- to ensure the skin starts slowing down it’s production of pigment in those areas and 2-to slowly start helping you lighten the existing marks. If your pigmentation is really severe, then its going to take quite a bit of time for you to see major improvements with just the topical products, so you may want to consider kick-starting the process with some treatments. To properly prescribe these we would need to take a look at your skin and see if you need any additional treatments or if there is anything else that we can do to further assist you in combatting this problem. Please feel free to contact any one of our Skin Renewal branches for any further assistance.
