I'm thinking of getting a skin booster for the first time. What is the difference between Rejuran and Liviheal?

Hello. Lately, my skin has felt generally dry and dull, and I feel like my makeup doesn't apply as well as it used to, so I am looking into skin booster treatments.

I looked it up and found there are so many types like Rejuran, Liviheal, and Exosomes, but I'm not really sure what the differences are between them. I am more concerned about skin texture, deep dryness, and improving subtle elasticity rather than enlarged pores.

I'm a bit worried about the pain, so I'm wondering how long the swelling or embossing usually lasts after the procedure. Since I work, I'd also like to know if I can go back to work immediately after the procedure. ㅠㅠㅠ

For first-time users, which skin booster do you recommend the most, and how many sessions are usually needed to feel the effects? I would appreciate your opinions if you have experience...!!!
