Should I start taking care of my eye wrinkles already? I'm in my 30s now...

These days, when I put on makeup, I see small wrinkles under my eyes, and I suddenly feel depressed ㅠㅠ

I haven't applied eye cream yet because I think it's too heavy. When did you all start taking care of your skin? Should I start applying it now, or is it okay to just apply moisturizer?

I heard that if you apply something too thick, it can cause seborrheic keratosis, so I can't just buy it. Sob. If there's a light but effective eye cream or eye care method, please share it with me!! When you think it's too late, it's really too late, right??ㅠ
