[Anti-aging] I don't have acne but I'm 30 and have some fine lines - should I be using a retinol?

Beauty Tips For Body Care
Having 8-12 weeks of red, peeling skin seems really not worth it given I have very little acne, but I kinda want to be doing everything I can to look like Helen Mirren when I'm 70. (I also have unevenish skin tone because I never used to wear sunscreen, sigh)Do low % serums (say, 0.5%) do any good, or is that just a waste of time/money?
