Direct collagen injections into the skin, Retigen



What if collagen is injected directly into the skin?



Hello.

This is Chief Director Kim Jang-ju.

When skin loses elasticity, pores get larger, and skin texture becomes rough,

many people consider collagen booster injections.

Existing injections irritate the skin

to induce the body to produce collagen on its own,

so the effects tend to appear slowly.

However, these days, the method of

injecting collagen directly is gaining attention.

If you want quick results and immediate changes,

the difference is clear.





❓ Retigen, what kind of procedure is it?




Q. What kind of injection is it?

A. It is a collagen booster injection that directly supplies collagen.

Since it’s a direct injection method rather than stimulation,

you can expect quick skin improvement effects.









Q. What is the difference from existing collagen injections?

A. Existing injections stimulate the skin

to indirectly induce collagen production.

In contrast, this procedure directly injects into the skin,

creating more certain and rapid changes.









Q. Does it work faster?

A. Yes. Many people feel changes in

elasticity, radiance, and texture within a few days after the procedure.









Q. Are the ingredients different?

A. It contains high-purity collagen combined with peptides and

antioxidant components,

which allows for more than just simple injection,

giving you expected skin regeneration effects.





💡 Where will the effect be noticeable first?





Changes are often felt first around areas

like the eyes, cheeks, and nasolabial folds,

which tend to lose elasticity easily.

In particular, nasolabial folds can give the impression of aging,

and after the procedure, those areas become softer,

leading many to feel that their whole face looks much younger.

The skin becomes plump and natural volume returns,

significantly enhancing customer satisfaction.

Moreover, as the skin texture smooths out and pores are refined,

you can definitely feel a difference in makeup adherence.

As the foundation goes on smoothly without clumping,

many report that makeup applies much better.

⚠️ Side effects & precautions





After the procedure, swelling, redness, or bruising may occur,

but most resolve within 1 to 3 days.

Rarely, bruising lasts for 5 to 7 days,

and there may be skin irritation or sensitivity reactions.

Therefore, it is essential to receive treatment from

experienced medical professionals,

and it is advisable to avoid sunlight and excessive stimulation after the procedure.





💰 How much does it cost?







It varies depending on the number of procedures

and the volume,

with 2cc costing 550,000 won.

As multiple treatments can solidify results,

if you proceed with a package of more than three times,

it reduces the cost burden and improves cost-effectiveness.

The exact cost may vary based on the skin condition and

area, so it is safest to receive

tailored guidance through a consultation.





💬 Pain & recovery?




The pain isn’t significant.

Since a numbing cream is applied before the injection,

it often ends up just being a slight sting.

You can generally go out right after the procedure,

but there might be some redness, slight swelling, or small bruises.

Typically, the redness lasts for 1 to 2 days,

and bruises disappear within 3 to 5 days.

On the day of the procedure,

💬 Avoid saunas, intense exercise, and alcohol

💬 Cleanse gently and minimize makeup

💬 Sunscreen is a must!





💬 Frequently asked Q&A



Q. When is the best season to receive the Retigen treatment?

A. All seasons are possible, but

it's better to receive it in

autumn and winter rather than the summer when UV radiation is strong

for quicker recovery and less irritation.

During periods of active skin regeneration,

the effectiveness lasts longer.









Q. Is post-treatment care difficult?

A. It is not particularly complicated.

For 2 to 3 days after the procedure, focus on moisturizing care,

and it’s better to avoid exfoliation, scrubs, and massages.

After three days, consistently use moisturizing cream and sunscreen.









Q. How long does the effect 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 severe skin elasticity degradation,

it is recommended to receive treatment 2 to 3 times at one-month intervals and

to have maintenance treatments every six months.









Q. Can men also receive it?

A. Of course.

Men with dehydrated skin or concerns about fine lines and

enlarged pores have high satisfaction levels as well.

The only difference is the injection depth depending on skin type,

but the principles of effect remain the same.









Q. When can I start wearing makeup or cleansing?

A. On the day of the procedure, cleanse gently,

and it is recommended to apply makeup the next day.

Avoiding irritation to the treatment area helps

facilitate quicker recovery.









Q. When can I exercise or go to the sauna after the treatment?

A. You can start after 48 hours.

Right after the procedure, there may be residual warmth, so please

avoid exercise, sauna, and alcohol.









Q. Will I be able to resume my daily life right after the procedure?

A. Yes, it is possible.

Even with swelling or bruising, most people

can cover it with makeup.

This procedure is classified as one that does not hinder

work or going out.

Thank you sincerely for reading all the way to the end.

I understand how precious that time spent searching

for skin concerns is.

While quick changes are important,

ultimately, safe care suited to your skin

is the greatest value I want to convey.

I will continue to share vivid information and

helpful stories that I have directly experienced

in the clinic.

Yours sincerely,

Kim Jang-ju.
