Just as Rejuran was starting to make sense, a new name shows up: the collagen injection. With so many skin boosters on the market, every new arrival adds to the confusion. This article looks at what Laetigen, the collagen injection drawing attention lately, actually is, and how Skinique Clinic approaches the procedure.

What kind of injection is Laetigen
Collagen injections fall into two broad groups. One stimulates the skin so that it produces collagen on its own; the other supplies collagen itself. Laetigen belongs to the second group, a preparation made up of 99.9% collagen that is delivered directly into the skin. Rather than waiting for new collagen to form, it replenishes what has been depleted, and that is the main difference from the skin boosters people are used to.

A Laetigen seminar held for fellow physicians
Skinique Clinic recently hosted a meaningful gathering. Dr. Park Tae-hyung, chief director of the clinic, took the podium and invited directors from a number of practices to a seminar on Laetigen. Because the audience was made up of physicians actively seeing patients, the session was built around practical clinical detail rather than product promotion.

At the heart of the talk was experience gathered from performing the procedure himself: how different skin types responded, what worked well and what fell short, organized into cases and data and shared without varnish.

The analysis that resonated most with the attending physicians covered where collagen injections differ from existing skin boosters, and which skin concerns and skin types they suit. Points that still need improvement were raised just as candidly, which is very much the character of this seminar: a good procedure comes out of continuous study and feedback, and that was the reason for holding it.
A live hands-on session, worth more than any explanation

After the lecture came the highlight of the day, a live hands-on demonstration. Scars, pores, wrinkles and loss of firmness each call for a different approach, and the attendees watched how Laetigen is handled in each of those situations.

Questions and answers kept the room engaged, and what gave the session its value is that it was not an event to publicize a particular product but a process in which physicians work together to raise the standard of the procedure. Exchanges like this, where a new treatment is examined and know-how is shared, eventually show up in the quality of care patients receive in the treatment room.

If you are considering Laetigen
Whether direct collagen replenishment suits your skin depends on your skin condition, the areas that concern you and your history of previous treatments. For some people a stimulation-type skin booster is the better fit, so a consultation should come before any trend in names.
Wrapping Up
Laetigen is a collagen injection that delivers a 99.9% collagen preparation directly into the skin, and Skinique Clinic studies it closely enough to hold a seminar and a hands-on demonstration for fellow physicians.
