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

Lately, when I look at my makeup, I feel like I can see tiny wrinkles under my eyes, so I suddenly got depressed.

I haven't been using eye cream yet because I thought it would be too heavy. When did you all start taking care of your skin? Should I start using it now, or is it okay to just apply a moisturizer?

I heard that using something too thick can cause milia, so I'm hesitant to buy just anything. *Sob* Please share any lightweight yet effective eye creams or eye care tips you know of!! If you think it's too late, it really is too late, right??
