Ive had dark circles since i could remeber. There a purple green color and I could see my veins, so I know for sure that its thin eye lid skin. One dermatologist said that Retin A could help if I use it for a long period of time, such as six months or more. So my question is , is it safe to use around the eyes? I have Retin A gel at the strength 0.04% How often should I use it. Thank you so much guys :)
