Wangsimni Dermatology: What Are the Effects of the Collagen Booster Retigen for Under-Eye Hollowing and Regeneration?

Under-Eye Retigen

Hello, this is Raon Dermatology in Wangsimni!

One of the first areas people look at is the under-eye area. Even when your facial expression does not change much, if the area under the eyes looks sunken, your whole face can appear tired, and you may even hear that you look older than you really are. The reason your impression does not easily change, even after enough rest, is often connected not simply to your condition, but to changes in the under-eye tissue itself. That is why eye-area care requires an approach that understands the skin structure, beyond just covering it with makeup :)

Causes of Under-Eye Hollowing

Under-eye hollowing may seem to be caused simply by weight loss, but in reality, changes in the skin’s supporting structure have a major impact. When collagen that supports the dermis decreases, the skin becomes thinner, and the fine contours under the eyes become more visible. In this process, the area under the eyes can look shadowed, making dark circles appear even darker!

The issue is less the hollowing itself and more the chain of changes it creates in your overall impression. When the under-eye area looks sunken, blood vessels are more likely to show through, emphasizing a darker tone, and the center of the face can look hollow, creating a more aged appearance. The feeling that your expression does not look as clear when you smile or talk is also connected to these structural changes.

• Thinner skin / more visible blood vessels

• Dark circles appear darker

• The center of the face looks hollow / a more aged impression

What Is Retigen?

Retigen is a collagen-based injection made from Type 1 collagen, and it is an approach focused on restoring the skin’s internal environment. Rather than simply filling space, it is meaningful because it directly delivers ingredients needed by the under-eye tissue and helps guide the skin toward its own recovery process.

Because the under-eye area has thin and sensitive skin, it is prone to irritation and unnatural changes~ Retigen is a collagen formulation designed to be applied around the eyes with these characteristics in mind, so you can expect gradual changes without excessive foreign-body sensation or an overly artificial protrusion after the procedure. That is why even those considering an under-eye procedure for the first time may find it relatively easy to approach.

Retigen Features

The biggest feature of Retigen is that it is a non-filler collagen injection. Instead of instantly adding volume, it is designed to be gradually absorbed and responded to by the skin tissue, so it does not damage the delicate structure unique to the under-eye area. As a result, it may help reduce unnatural visibility that stands out with facial expressions.

It also uses Type 1 collagen, which is relatively well absorbed by under-eye tissue and tends to be less irritating. The procedure time is usually short, around 10 to 20 minutes! Another feature is that you can return to daily life right after the procedure. It is not just about changing the skin surface; over time, the skin’s regeneration response continues, and you can expect a more refined, firmer feel.

Main Effects of Retigen

Improvement of under-eye hollowing is one of the changes people notice first. As the contour of the sunken area becomes smoother, the shadow under the eyes is reduced, leading to a brighter overall facial impression. Because the volume change is not excessive, many people around you may not even notice that you had the procedure.

Reduction of dark circles can also be expected. As the collagen environment is supplemented in the under-eye area, where thin skin made blood vessels stand out, the tone becomes much softer. In addition, if collagen regeneration in the dermis is promoted, it can have a positive effect on maintaining skin elasticity over the long term. This is why it can be an option for those who prefer a natural recovery process over fillers.

• Improvement of under-eye hollowing / brighter overall impression

• Supplementing skin thickness / easing dark circles

• Improvement of fine wrinkles around the eyes / natural volume restoration

• Increased under-eye elasticity over the long term

Retigen Procedure Guide

Retigen is usually performed at 2- to 4-week intervals, and depending on the skin condition, 3 to 5 sessions are often recommended. Rather than creating a big change all at once, you can think of it as gradually building up the skin’s response step by step! That is why keeping up with the procedure at appropriate intervals is important.

After the procedure, it is best to minimize washing your face or applying makeup on the same day. Bruising or swelling may occur, but in most cases, it subsides within 1 to 3 days. Afterward, combining moisturization and regenerative care can help skin recovery, and drinking enough water also has a positive effect on maintaining the condition of the under-eye skin. If you are concerned about under-eye hollowing or damage, we hope you will seriously consider Retigen, which we covered today :)
