My facial lines feel like they're becoming indistinct. How do you manage this?

Lately, I’ve been noticing more and more that I’m not the same as I used to be when I take pictures or look in the mirror.

My jawline used to be slim and distinct, but lately, my overall facial lines feel like they have collapsed and become rounded.

I’m so upset because my cheeks and jawline seem to be sagging, even though I haven’t gained weight. Would simple massages I can do at home, or lymphatic circulation massages using tools like gua sha, be effective?

Or is the answer to consistently use functional cosmetics like firming creams or serums? I am also considering getting a lifting procedure at a dermatology clinic, so I would like to know which treatments are effective, or hear any experiences or tips from those who have regained elasticity through home care.

Please advise on good care methods, ingredients, or effective treatments.
