The question is what does a 'standard' 50, 60, 70, 80 year old look like in order to decide whether they or any beauty treatment they use makes them look younger than they are.
The same with wrinkles. How many wrinkles does the average 50, 60 etc year old person have?
What people look like, or more often the impression that they give of their age is based on so many other things other than how many wrinkles you have - health, genetic inheritance, life experience, personality, how you dress, how you stand and present yourself
Like most women I look after my skin and duly felt satisfied and complacent when my 15 yearold DGD, commented on my lovely smooth skin, but I have no illusions that anyone other than her is going to notice, and certainly do not think it makes me look 'younger'. As I said compared with who?
I am quite happy to feel I look good for my age, further than that the details are irrelevant.
