How to build up the strength of my skin? 45 y/o looking to thicken/strengthen skin, esp around eyes.

I feel like my skin is too delicate and sensitive and needs strength, maybe collagen. I've been told maybe Obagi .05 Retin-A & Obagi Blender FX with some Vitamin C and Peptides. Also I've been told microneedling could help. But then a natural skin care therapist told me Retin-A will thin & damage my skin. What should I do? I really need a protocol to build up the strength of my skin and help with fine lines I'm & thinness I'm seeing, esp around eyes but I'd like more robust skin in general.
