You needn't be concerned. The tiny openings from the needle used for your Kybella treatments have closed by now, and you can apply Retin-A. However, because your skin is somewhat inflamed, you may want to use it less frequently than previously, perhaps every three or four nights, until you see whether or not it irritates your skin. All the best! Dr. Clark
If your skin is tender from the injections, then I recommend holding off on the Retin-A for a few nights, since it can further irritate the skin. However, if you have no tenderness, you do not need to stop the Retin-A.
