How to improve your skin

Please tell me ㅠㅠ As I get older, my face has become much more swollen.

There are a lot of freckles on my face...

It feels like there's something wrong

Actually, I wasn't very good at taking care of my skin...

Do you have any home care routine recommendations?

Or I wonder if I should get a separate treatment at a dermatologist ㅠㅠ
