Direct collagen injections into the skin, Retigen



Collagen, if injected directly into the skin?



Hello.

This is Director Kim Jang-ju.

When you feel that your skin's elasticity has decreased, pores have noticeably enlarged, and

your skin texture has become rough,

many people start to consider collagen booster injections.



Existing collagen injections induce our skin to produce collagen by giving it a stimulus,

so the effects tend to appear gradually.


On the other hand, recently, a method of directly injecting collagen into the skin is gaining attention.


Because it is an approach that immediately supplies the necessary components,
many people feel improvements in skin elasticity, shine, and texture more quickly and intuitively.


In other words,

if you desire quick effects and immediate improvement in skin condition instead of waiting for gradual changes,

the difference between the two methods can be clearly felt.





❓ What is Retigen, and what kind of procedure is it?


Retigen is not an injection that stimulates collagen production,

but a collagen booster injection that directly supplements the collagen needed by the skin.



If existing collagen injections worked by giving slight stimuli to the skin,

inducing indirectly the creation of collagen,


Retigen is a method that directly injects collagen into the skin,
which is the biggest difference as it allows for faster and more certain skin changes.



So after the procedure, many people feel

an immediate sensation of plumpness or elasticity, and see improvements in texture within just a few days.



Additionally, there are differences in the components used.

Using high-purity collagen as a base,

with the addition of peptides and antioxidant ingredients that aid in skin recovery,

it goes beyond just filling in wrinkles.

You can expect a procedure that also promotes skin regeneration and condition improvement.





💡 Effects,

Where will they appear first?


In areas where elasticity easily decreases, such as around the eyes, cheeks, and nasolabial folds,
changes are often felt the most quickly.

In particular, nasolabial folds can easily give a perception of aging,

and after the procedure, as this area becomes smoother,

many people find that their entire face looks significantly younger.

As the skin becomes plumper and natural volume is restored,

clients express their satisfaction significantly.

Additionally, as the skin texture becomes smoother and pores are refined,

you can definitely feel the difference in how makeup adheres.

Since foundation applies smoothly without lifting,

there are many reviews stating that makeup stays on much better.






💰 What is the cost?


The cost varies depending on the number of treatments and the amount used,

starting at 550,000 won for 2cc.

The more treatments you receive, the more effective the results become,

​and if you receive a package of more than three sessions, it reduces the financial burden and increases cost-effectiveness.


The exact cost may vary depending on your skin condition and the areas treated,

so it is safest to receive a customized consultation.






💬 Pain & Recovery?


The pain is not significant.

Since a numbing cream is applied before the injection,

it usually ends up being just a slight prick.

You can go out immediately after the treatment, but

there may be redness, slight swelling, or small bruises.

Typically, the redness lasts for 1 to 2 days,

and the bruises disappear within 3 to 5 days.

On the day of treatment,

🙅🏻‍♀️Avoid sauna, intense exercise, and alcohol

🙅🏻‍♀️Cleanse lightly, and minimize makeup

🙅🏻‍♀️Sunscreen is essential!







📌 Frequently Asked Q&A


Q. When is the best season to get Retigen treatments?

A. It can be done year-round, but

it is better to have it in autumn or winter rather than during the strong ultraviolet rays of summer,

for faster recovery and less irritation.

Because skin regeneration is active during this period,

the durability of the effects is also generally longer.






Q. Is the post-treatment care complicated?

A. It’s not particularly complicated.

For the first 2-3 days after the treatment, focus on hydration and

avoid exfoliation, scrubbing, and massage.

After 3 days, you should consistently use moisturizing cream and sunscreen.






Q. How long do the effects last?

A. Even with just one treatment,

you can feel improvements in skin texture and elasticity,

and the effects last for about 3 to 6 months.

For those with significant loss of skin elasticity,

it is recommended to have 2 to 3 treatments at one-month intervals

and to perform maintenance treatments every 6 months.







Q. Can men also get this treatment?

A. Of course.

Men who have dry skin or are concerned about fine lines and enlarged pores

are also very satisfied.

The only difference is the injection depth depending on the skin type, but the principle of effect is the same.







Q. When can I start wearing makeup or cleansing?

A. On the day of treatment, you can cleanse lightly,

and it is recommended to start wearing makeup from the next day.

Avoiding irritation to the treated area helps speed up recovery.







Q. When is it okay to resume exercise or sauna after treatment?

A. It is possible after 48 hours.

Immediately after the treatment, you may still feel warmth, so please

avoid exercise, sauna, and alcohol.







Q. Can I go back to my normal daily routine right after the treatment?

A. Yes.

Even with swelling or bruising, in most cases,

it is at a level that can be covered by makeup,

and it is classified as a procedure that does not interfere with work or going out.
