How about the affordable event Botox price?

My nasolabial folds are particularly severe on one side, so I'm looking into getting injections at various clinics. As expected, since Botox is a standard procedure, many clinics are offering it at affordable promotional prices. While searching, I found some places where it costs less than 10,000 won per area. Has anyone had experience getting Botox at such a low price? I'm curious if the effects were minimal or what kind of results you experienced.
