Green cream is a retinol. Retin-a micro is tretinoin, which is a lot stronger than retinol. I don't think I would have ever tolerated the retin-a micro if I hadn't used the green cream first. I built myself up to using the Green cream every night. I have very sensitive skin. The nice thing about green cream is that I can use it under my eyes, on my eye lids, lips, neck, and chest. I don't have to wear make up under my eyes anymore thanks to the green cream! Green cream has a website if you want to learn more about it.

regarding the retin-a micro. Has anyone noticed more oily skin while using RAM? My skin looks pretty oily when I wake up in the morning after using it. It also seems more oily during the day. I don't know. Maybe it's the mineral makeup I started using around the same time. My skin has never been this oily. In fact, I usually have pretty dry skin in the winter and normal to combination in the summer. Now it is totally oily. Anyone else have this happen?
