DIY eyelash perm

There seem to be a lot of DIY eyelash perm products coming out these days. Has anyone tried using them?

I don't think very cheap products will be effective, so I'm planning to buy a product in the 20,000-30,000 won range.

I am curious about the effectiveness, but I am also worried about whether the medication might have side effects.

I was looking around and am thinking of buying a Merrysood product. Has anyone used it?

Please let me know what you think! (I would also appreciate it if you could recommend other products!)
