Retigen Delivers Collagen Instead of Prompting It | Gangnam Seoul, Korea Dermatology Clinic Guide

When people who have tried various Skin Boosters ask about Retigen, they sometimes have a certain nuance.

"Is this another procedure that makes collagen?"

But this is a bit different.

Instead of stimulating the skin to make collagen, it's about injecting collagen itself.

Please take just one minute to read this.

Stimulating vs. Supplying Types

This difference has one practical meaning:

The perceived effect of stimulating types may be weak in skin with reduced regenerative capacity.

If the skin is signaled to produce, but lacks the capacity to do so, results will be slow to appear.

So, who is it suitable for?

• Those who have received various Skin Boosters but felt little effect.
• Those whose regenerative capacity appears to have decreased due to age or accumulated irritation.
• Those who experience both rough skin texture and a thinned feeling.

Conversely, if regenerative capacity is maintained and the only issue is hydration, a hydration-focused treatment might be more suitable.

This is not because Retigen is a better treatment, but because its target is different.

(※ Effects and reactions may vary depending on individual skin condition, and suitability for the procedure is determined through consultation with medical staff.)

Explanations to check during consultation

Since it's a procedure with a different principle, you should check if the following are explained:

"Is my skin's problem currently regenerative capacity, or hydration?"

"What did you base that judgment on?"

"How many sessions are planned, and what is the interval between sessions?"

If only product names and prices are discussed without an explanation of the principle, it can be difficult to confirm if the choice is tailored to your condition.

How to understand individual differences

Even if you receive the same procedure, the perceived effects can differ because the starting points are different.

If you start with significantly reduced regenerative capacity, the range of change may feel large, but more sessions might be needed. If you start in a relatively good condition, the range of change may feel smaller.

This is why it's difficult to directly transfer the satisfaction levels from reviews.

The structure of conflicting reviews was covered in Why Skin Booster Reviews Disagree.

Frequently Asked Questions

How is Retigen different from other Skin Boosters?

While most Skin Boosters work by stimulating collagen production, Retigen directly injects Type 1 collagen into the dermis.

Can I expect results even if my regenerative capacity is low?

It is less dependent on the skin's regenerative capacity compared to stimulating types. However, there are individual differences.

Should I get it if I haven't felt results from other Skin Boosters?

If the cause was related to regenerative capacity, this approach might be suitable. If the problem was hydration, a different type might be more appropriate.

How many sessions are usually performed?

It varies depending on the initial condition. The interval between sessions is determined during consultation, tailored to the characteristics of the ingredients.

What are the reactions after the procedure?

Red spots, swelling, and bruising may appear at the injection sites. The degree and duration vary individually.

Recovery and Downtime: Course of Injection-Based Procedures

Red spots or small swelling may remain at the injection sites for a day or two.

It is advisable to avoid saunas and strong massages for the first two days.

Changes in skin texture appear gradually over several sessions.

How is the cost structured?

The cost is not determined by the price per session alone.

It varies depending on the area, total number of sessions, combination with other ingredients, and whether anesthesia and soothing care are included.

For an accurate cost, it is best to provide guidance after a consultation to assess your skin condition.
