My skin is seriously hopeless right now............

Overall, the glow has disappeared and it feels like it has lost its vitality,

so I get really stressed every time I look in the mirror..

I've been to dermatologists and even tried treatments,

but my wallet just ended up empty and I don't really see any noticeable improvement..

So I'm looking into inner beauty products,

and while watching YouTube, I saw a video by Cha Ye-ryun about ingestible PDRN and got kind of intrigued?

Has anyone tried it??
