I envy the skin of someone in their 20s..

Looking at my old photos, my skin used to be so firm. But lately, it has lost its elasticity, my pores have gotten bigger, and fine lines are appearing. I want to get something that works for sure, even if it costs a bit. While searching, I found out about the Evercle Birth Injection.

Is it true that it uses PDRN and regenerates collagen at the same time? Could anyone who has tried it share their experience?

Or I'm debating if I should just get Rejuran instead.
