What is the Libby Hill effect?

I've been seeing a lot of mentions of Libby Hill in the community lately, so I became interested, but when I actually looked it up, I found out they have exosome skin boosters and a cosmetics line, so I wasn't really sure what was what.

Exactly what are the effects of Livy Heal? I’m curious if it focuses simply on skin radiance or hydration, or if I can also feel a noticeable improvement in overall regeneration or elasticity. In particular, among the Livy Heal products or treatments, could anyone recommend the most satisfying option for a beginner?

I would be really grateful if you could share honest reviews from those who have actually used it, or some tips on what kind of concerns would make it a good choice!
