Ladies, have you tried collagen supplements and retinol skin products?

Considering starting to use them as based on my own research, your 20’s is when you should start, and im starting to get signs of aging (which is normal, I know). Are these products actually worth using or is it just a hoax? Did you notice any difference after using collagen & retinol?
