My go to... Review by Janet
After washing my face, morning and evening, Super Serum Advance is the first thing I put on my skin. I have been using it for 8-10 years. People are always amazed when I tell them how old I am, so this serum really works! (Posted on 1/3/19)
Good review Review by Shari
I have used this product somewhere around seven plus years. It is a well formulated product for healthy supple skin. At age 69, there is no need to choose makeup, healthy is good.
