I have been using Renova the past 10 days. Around my eyes on my forehead and over my lip. Too soon to see a change in lines, but my husband said my face is glowing. I am a super S and the low dosage, .02% and the cream base seem not to cause a reaction. Anybody used Renova on their neck? If I am S on my face, I am delicate on my neck. The skin on my neck is good and I would not like to come out looking like a turkey. I still have my red T-zone, but have been using the green Eucerin moisturizer with foundation and without. That stuff is great. I'm just surprised with our skin type I could wear Renova when the Olay and Neutrogena serums gave me red spots bumps and burns and tingling from the first day of use. Go figure. Hope I helped someone on this forum.
