At what age is it best to start wrinkle care?

Hello~! I'm in my mid-20s, heading into my late 20s now ㅠ_ㅠ!!

In my early 20s, I didn't really do much in terms of hydration or facial care.

I was starting to think I should start taking care of my nasolabial folds and under-eye wrinkles... ㅠㅠ!!

By any chance, at what age did you start taking care of your wrinkles, and how did you do it?
