Collagen or retinol/al?

[Doghairinmybed]

I want to upgrade my skincare but am so baffled by all the options. I’m 48 and have fine lines which is priority no 1. Temped by collagen (oral
and serum) but retinol/al seems to be the holy grail? What works for you? Thanks

I quite like Avon retinol products. Works better than some of the more expensive brands.
