Hi Kerry. I have been using Olay Regenerist (red jar) in the morning and Regenerist with retinol (purple jar) at night. It has helped. I also use hyaluronic acid in the morning and sometimes evening before applying the moisturizer. Here is a great source for the HA.
I have thought about using retinol serum and even tried it once or twice. You have to be careful applying it because it can cause a break out of sorts if too much is applied. I am sure once you learn how to apply it it would be easy. Retinol should only be applied in the evening because it makes you sensitive to sun burn.
Don’t forget to apply sunscreen.🥰
