Hello.

I’m Beauty’s Doctor, Wi Young-jin.

So far, what we have commonly called collagen injections,

procedures such as Sculptra, Radiesse, and Juvelook are not actually methods that directly inject collagen.

These procedures work by giving the skin a mild stimulus and inducing our body to produce collagen on its own.

So the more accurate term is collagen-inducing injections.

That naturally leads to this question. Is it possible to inject collagen directly? What kind of procedure is Retigen?

Retigen is a procedure that takes a completely different approach from the existing methods.

It is not about waiting for collagen production.

It directly injects highly purified animal-derived collagen into the dermis to fill and support the skin structure.

In other words, the key is filling the skin directly with collagen itself.

The collagen injected in this way stays in the skin for a certain period of time and plays a structural role.

It smooths skin texture, helps improve elasticity, and fills in density.

Rather than an immediate volumizing effect, it is closer to improving the quality of the skin itself.

This is an important point that is also explained in detail during consultations at dermatology clinics in Dangsan. How effective are collagen injections, and how much can you expect?

When the skin texture is uneven or pores have become noticeably enlarged, external care alone has its limits.

Because Retigen directly fills the dermis, more structural improvement can be expected.

So the changes tend to be relatively quick and noticeable.

Unlike existing collagen-inducing injections, the injected ingredient begins working immediately, so the response is also relatively fast.

In conclusion, the core benefits of collagen injections can be summarized in three points.

Improved skin texture,

enhanced elasticity,

and increased density.

The biggest feature is that these three improvements happen at the same time.

This is also a change that is often directly felt at dermatology clinics in Dangsan. Are the effects different by area? One advantage of Retigen is that it can be flexibly applied to different areas.

It can also be used on thin skin.

Around the eyes, it can help smooth fine lines and improve elasticity, but there is a possibility of bruising.

On the cheeks, it can be effective for improving pores and skin texture, but if there is volume loss, combination treatment may be needed.

In the nasolabial fold area, it can help improve skin density, but it is more focused on texture improvement than lifting.

Along the jawline and neck, it helps tidy up sagging skin texture, but it is not a procedure meant to deliver a strong lifting effect.

As such, it is important to design the treatment with each area’s characteristics in mind, and this is the basis on which procedures are carried out at dermatology clinics in Dangsan. Treatment interval and duration Retigen is usually performed at 3- to 4-week intervals.

A total of 2 to 3 sessions is generally recommended.

Some people may notice a change after just one session, but

repeated treatments are needed to maintain collagen density.

Although results vary from person to person, they generally last for more than 6 months on average.

This can be seen as having longer-lasting effects than existing collagen-inducing treatments.

This is also important information that is often provided during consultations at dermatology clinics in Dangsan. Pain and side effects Because this is a procedure injected into the dermis, it would be hard to say there is no pain at all.

Even with numbing cream, some areas may feel a sting or tenderness.

Also, due to the nature of animal-derived collagen, there is a possibility of allergic reactions.

Therefore, a pre-procedure test and consultation are essential.

These steps are also always carried out at dermatology clinics in Dangsan. Differences from existing collagen injections Collagen-inducing injections work by gradually producing effects as time passes.

In other words, they are treatments that require waiting.

By contrast, Retigen works immediately because the injected ingredient begins acting right away.

The induction method requires time, while the direct injection method shows a quicker response.

It is important to understand this difference. Pre- and post-procedure care Before the procedure, it is best to avoid alcohol and excessive exercise.

Reducing irritation to the skin is also an important point.

After the procedure, washing your face and applying makeup are possible after 4 hours.

It is best to avoid irritating exfoliating products for about a week.

Sun protection is essential.

When this care is followed, it helps maintain the effects of the procedure. Combined procedures Retigen can be combined with various other procedures.

If performed together with lifting procedures, you can expect improvements in both elasticity and skin texture.

When combined with skin boosters, the moisturizing effect and skin quality improvement are further enhanced.

However, the order and interval of procedures will vary depending on individual skin condition.

Therefore, it is important to proceed only after consultation.

This is also something that dermatology clinics in Dangsan advise in a customized way. Frequently asked questions Q. Can I get it just once?

A. There can be effects from one session, but 2 to 3 sessions are usually recommended.

Q. Can it be done together with other procedures?

A. Yes, it can. However, the area and order need to be adjusted.

Q. Is it okay if my skin is thin?

A. Yes, it is possible. But the possibility of bruising and pain should be considered.

Retigen is a procedure that directly injects collagen.

Unlike the existing method of inducing collagen production, the injected ingredient works immediately, so there is a difference in response speed.

This difference in mechanism leads to a change that does not simply improve the surface, but fills in the skin structure itself.

As a result, you can expect improvements in skin texture, elasticity, and density at the same time.

This structural improvement also tends not to be temporary, and is characterized by lasting for about 6 months or more.

However, to maintain the effects stably, customized application that takes into account skin thickness and condition by area is important.

In the end, to feel the benefits of collagen injections more directly, understanding the difference in treatment methods is the key.

Thank you for reading this long post. This was Wi Young-jin.
