I want to know who Livicol is recommended for!

Now that I've entered my 30s, every time I look in the mirror, I painfully realize that my skin isn't what it used to be. ㅠㅠ Sob sob

I felt like cosmetics alone had their limits, so while looking into various options, I naturally became interested in skin boosters, which are apparently trending on online communities these days.

I’ve seen the name Rivicol mentioned particularly often, and I’m really curious about exactly which skin types it works best for. Could someone like me, who feels severe internal dryness right after washing my face and notices fine lines around my eyes, see significant improvement with Rivicol? I seem to have vaguely heard that the results vary or have differing effects depending on an individual's skin condition. If there are any seniors out there who have tried Rivicol for similar dry skin concerns, I would be incredibly grateful if you could share your honest opinions on what you found most satisfying!
