The Main Injectable Categories, Described Generically

Korean clinic menus draw on a handful of broad injectable families — muscle-relaxing neuromodulators, volumising fillers, slow-acting biostimulators, hydration-focused skin boosters and fat-reducing solutions — and the branded name on the menu almost always sits on top of one of them. Knowing the family tells you far more than the brand does. These are medical products carrying medical risks; nothing here is a recommendation, and an in-person consultation with a licensed doctor is the only appropriate route.

Five families, described plainly

Neuromodulators temporarily reduce the contraction of specific muscles. Fillers, most often based on hyaluronic acid, occupy space and add contour where they are placed. Biostimulators work indirectly and slowly by prompting the body's own response over weeks or months. Skin boosters aim at the look of hydration in the upper layers rather than at shape. Fat-reducing injections act on fat tissue in a defined area. Those five behave differently, last different lengths of time, and carry different consequences when something goes wrong.

Why menu names obscure all of this

Clinics name programmes rather than substances, often combining a place name, a celebrity-adjacent adjective or an English word with no technical meaning. The same brand-named product can be marketed under several programme names at different clinics, and the same programme name can cover different products across the street. Asking which family a proposed injectable belongs to, and then which specific licensed product will be used, cuts through the naming immediately. A clinic that will not answer that clearly has told you something useful.

Counterfeit and unlicensed product is a real hazard

Injectables sold unusually cheaply, offered outside a proper clinical setting, or administered at events, salons or private homes are a recognised problem in many markets, Korea included. Products for medical use in Korea go through the national regulator, and a legitimate clinic can show you sealed packaging with Korean labelling before it is opened. Asking to see the box is normal and reasonable. Declining that request, or opening product out of sight, is a reason to stop and reconsider rather than to negotiate.

The risks, and where the decision belongs

Bruising, swelling, asymmetry, palpable lumps and infection are the common concerns. Vascular occlusion — filler entering or compressing a blood vessel — is the serious one, and it is a medical emergency requiring immediate attention, particularly if it involves vision or skin turning pale or dusky. Reversibility differs sharply between families, which is worth understanding before rather than after. This page states no criteria for who should have anything, recommends nothing, and defers entirely to a licensed doctor examining you in person.
