I used prescription retin-a for years with terrific results. I used it as an anti-aging product as I am now 54. Suddenly 2 years ago I developed eczema on my face, chest and neck and had to stop using it. Can you suggest an alternative that will not cause my eczema to flare? Currently I use skinceuticals vitamin c serum, a good rose hip oil and a moisturizer for my condition with good results but nothing like the good results I once had with Retin-a. Thank you!
