Please tell me how to care for your legs after a leg lifting procedure.

Recently, I received a leg lifting procedure to improve skin elasticity and address my double chin concerns.

I felt almost no pain during the procedure, only a warm sensation, so I was very comfortable. After a few days, I can definitely feel my lines becoming more defined, so I am very satisfied. I am writing because I would like to maintain the effects of this Ondari Lifting for a little longer, so I would like to ask a few questions about home care after the procedure.

I was advised to apply sunscreen and moisturizer properly after the treatment, but I am wondering if it would be safe to use a functional ampoule (containing retinol or Vitamin C) immediately. Also, as I want to maximize the effects, I would appreciate it if you could recommend the interval between additional Ondari Lifting treatments to achieve the best synergistic effect.
