RedBone since you have sensitive skin its probably better to start with the smallest dose of tretinoin, which is 0.025%. If that agree with you or you see minimal results then you can move on to the 0.05%. Then the 0.1% is the strongest. Now you say you have eczema? My sister has eczema on and off, and you know what? Her dermi prescribed her a steroid cream that not only controlled the eczema but lightened her skin. Her doctor said she used so much that it thinned her skin and the eczema ultimately came back, but she didn't know why. Her skin was so fair and beautiful, but you could never tell her skin had thinned; it looked healthy nonetheless. Ultimately what I am saying is steroid creams will work to control your eczema, and will lighten your skin, but you cannot use steroid creams for too long because of there are other dangers, and steroids get absorbed in your bloodstream after a while, but it works for eczema and lightening is my point.
