These days, I feel every day in the consultation room how popular skin booster treatments have become.
At Cordia Clinic, the number of people who regularly visit for Samseong Station skin booster treatments has noticeably increased.
When these individuals first visited, they felt a great deal of anxiety as much as anticipation.
‘Why are there so many types of skin boosters?’ ‘The names all sound similar, but what's the difference?’ ‘It's injected directly into the face, is it really safe?’
They poured out these questions as soon as the consultation began.
These are natural concerns.

Because it's a procedure that injects ingredients directly into the face, specifically into the dermis.
So, during consultations, I tell them:
‘It's not too late to decide after understanding what the ingredients are, how they work in the body, and what clinical results have been confirmed, one by one.’
Today, I'll summarize the two most frequently asked about Samseong Station skin boosters: Rejuran and Juvelook.
<Treatment Philosophy>
Rejuran: A Regenerative Ingredient from Salmon.
The core ingredient of Rejuran is polynucleotide (PN).

It's purified from salmon DNA, and its structure is similar to human DNA, so it causes less irritation.
When this ingredient enters the dermis, it stimulates fibroblasts to induce collagen production and helps repair damaged tissue.
It's closer to the concept of boosting the skin's own regenerative power, rather than simply replenishing moisture.


There's also clinical evidence.
In a Phase 3 clinical trial published in the Journal of the Korean Medical Association, 72 patients with fine wrinkles around the eyes were treated with Rejuran and hyaluronic acid filler on opposite sides of their faces for 12 weeks. The Rejuran-treated area showed more significant improvements in elasticity, collagen structure, surface roughness, and wrinkle depth.
Subsequent accumulated studies have also repeatedly confirmed improvements in skin thickness, texture, and elasticity.
Juvelook: A Biodegradable Ingredient Involved in Collagen Production.
Juvelook works differently from Rejuran.

Its main component is a biodegradable polymer called PDLLA (poly-D,L-lactic acid).
It also contains hyaluronic acid, so initially, hyaluronic acid provides immediate hydration, and then PDLLA slowly breaks down, continuously stimulating collagen production over a longer period.

PLLA, which is in the same class as PDLLA, has long been widely studied as a collagen stimulator.
Histologically, there are reports of significant increases in type 1 and type 3 collagen between 6 and 24 months after treatment.
Recent aesthetic medicine review papers also recognize it as a representative substance that stimulates neocollagenesis.
Therefore, in Samseong Station skin booster consultations, Juvelook is recommended as a good option for those with thin skin texture, lack of elasticity, or who want to improve overall skin density.
Which Skin Booster is Right for Me?
Rejuran and Juvelook, frequently mentioned skin boosters, are treatments with different ingredients and mechanisms of action.
Therefore, it's difficult to give a definitive answer to the question, ‘Which one is better?’

The direction of treatment can only be determined by considering your skin condition, age, desired results, and the duration you wish to maintain them.
This is why Cordia Clinic meticulously diagnoses during Samseong Station skin booster consultations.
The recommended ingredients vary completely depending on whether your concern is texture, elasticity, or the need for regeneration.

Some individuals may benefit more from combining both, while others might find focusing on one more suitable.
So, if you have any questions, I recommend not deciding based solely on online searches, but rather having a comfortable consultation first.
If you have any skin concerns that bother you these days, not just about skin boosters, feel free to leave a comment with your inquiry.
I will carefully review each one and respond.

Thank you.
