Skincare for my Mother

I'm fairly new at TO skincare (about 8 months in and just now branching into the BHA peel) but my mother is now asking for suggestions and I need help.

Her biggest concerns are aging, wrinkles, etc (she's 60 and never really done any skincare). I want to start her off slow and was seeing things about "the buffet" in other posts and am a bit confused on what this is - is it the multi-peptide with HA? HA was one of the things I wanted to start her on!

Thanks in advance!!
