Special collagen injection Retigen

Special collagen injection Retigen

Are you really injecting collagen yourself?



Hello.

I'm Director Kim Ha-won.

These days, you've probably heard

"I had a collagen booster" a lot,

right?

But did you know that the treatments we commonly hear about,

such as Sculptra, Radiesse, and Juvederm,

do not actually directly inject collagen?



So what have we been getting until now?
What was it?

​​

You don't have to worry.

It's not that it has no effect.

To be more precise, these treatments are

'collagen-inducing injections.'

They stimulate the skin to encourage it to

produce collagen on its own.

But here's the thing.


There are also treatments that actually
inject collagen directly.



Introducing the Retigen I will present today.








Why Retigen is special




Retigen directly injects purified high-purity animal collagen

into the dermis of the skin.

While other treatments induce collagen production,

Retigen delivers collagen itself directly.





This is a good thing.


🩵It stays in the skin for up to 6 months or more.

🩵Your skin texture will become noticeably smoother.

🩵Elasticity gets firmly restored.

🩵The effects start immediately.





What is different?



If your skin texture is rough, pores are enlarged, and

elasticity has decreased,

moisturizing alone won't be enough.

Other collagen treatments take time to show effects,

but Retigen starts working immediately after injection.


Three aspects will improve simultaneously.


🩵Skin texture correction.


🩵Elasticity enhancement.


🩵Skin density improvement.





Where can it be injected?



Retigen has another advantage.

It can be safely used in areas

where the skin is thin.

🩵Around the eyes

It is effective for fine lines and elasticity improvement.

🩵Forehead and between the eyebrows

It helps reduce frown lines.

🩵Cheeks

When you need to fix pores and skin texture.

🩵Nasolabial folds

When you want to enhance skin density.

🩵Chin and neck

When you need to improve skin texture.

Especially around delicate areas like the eyes or cheeks,

it shows more uniform and natural results.





How many times should it be injected?



Usually, it is recommended to get

2-3 times at intervals of 3-4 weeks.

However, it may vary from person to person.

Many people notice a change even after just one session,

and the effects typically last for over 6 months.

Compared to other treatments,

it definitely lasts longer.





How much pain is there?


Even with anesthesia cream,

as it goes deep into the dermis,

you may feel a prickling or pressure sensation.

And since it is animal-based collagen,

there may rarely be allergic reactions.

If you are searching for a clinic in Hapjeong,

I recommend visiting places where you can do a skin test and consultation before treatment.





I'll also tell you about side effects


🩵 Bruising or swelling

may temporarily occur immediately after the injection.

Most disappear within a few days.

🩵 Pain or tenderness

can occur because it is injected into deep layers.

🩵 Allergic reactions

are very rare but possible.

That's why pre-testing is important.





Can it be combined with other treatments?


Yes, it is possible.

In fact, the synergistic effect is better.


There are recommended combinations.



If combined with lifting (Ultherapy),
it can improve elasticity and skin texture at the same time.
If combined with skin boosters or gloss injections,
it can enhance both hydration and density.

​The order and intervals must

be discussed with your medical professional.





Frequently asked questions


What is different from other collagen treatments?

Other treatments induce collagen production.

Retigen directly injects collagen itself.

That's why it's called a 'real' collagen booster.







How many times should it be injected?

It varies by person,

but it is generally recommended to have 2-3 sessions.

Many people feel a difference after just one session.







How long do the effects last?

Usually for more than 6 months.

It tends to last longer than other treatments.

If you take good care, it may last even longer.






Is it very painful?

Even with anesthesia cream,

depending on the area, you may feel a prickling or tenderness.

However, it's bearable.








Today we learned in detail about Retigen,

which directly injects collagen.

Skin concerns exist for everyone.

What's important is to know the correct information and
make safe choices.

I hope this article has been helpful for you.
