Fine wrinkle concerns!! How are you managing your skin elasticity?

Is it because it's summer(?) I feel like my skin elasticity is decreasing, which worries me. My under-eye area also looks a bit saggy, and I notice fine lines when I smile, so I'm really unsure whether I should get a treatment. What kind of home care products would be good?

I'm using galvanic therapy, but it's not very effective, so I haven't been using it.

These days, there are so many devices, I was trying to find out which product to try, and my head is spinning ㅜㅜ. I would appreciate advice from users. Treatments, home care products, cosmetics, etc!!!
