Injectables — botulinum toxin for muscles and hyaluronic-acid filler for volume. Fast, non-surgical, and the entry point for a lot of Seoul "petit" clinic visits.
Also called: injectables, lip filler, skin botox, jaw botox, petit surgery
What to ask about: Ask the product brand and units/cc — cheap quotes often mean diluted toxin or unbranded filler. Filler in the wrong plane is the most common complication; confirm hyaluronidase (dissolver) is on hand.
