I have been re-reading "The Book" and have a question. Dr. B's CHOICE for serums (DRPW) is LaRoche-Posay. She also recommends SkinCeuticals (both CE Ferulic and C+AHA) serums. I recently started using the LP serum. I have noticed many posts about Skinceuticals on the forum and am thinking that it might be your favorite. Please give me input on which you are using (of the three) and why you like it. I am trying to get rid of vertical lip lines,deep lines at nose to mouth and sun spots.
Thanks.
