Myeongdong Laetigen ⎮ How Collagen Boosters Help Improve Wrinkles

 Hello,

I’m Dr. Youjoo Hwang, 

Director of Lijin Clinic in Myeongdong, Seoul.

Recently, 

more people have been moving away from treatments 

that simply add volume, 

and are instead looking for procedures 

that improve the overall quality and condition of the skin itself.

Rather than dramatic or overly noticeable changes, 

many patients today prefer results 

that look naturally refreshed 

and continue to feel comfortable 

and harmonious over time.

As this trend continues, 

more patients visiting our clinic 

in Myeongdong for wrinkle concerns 

have also become interested in Laetigen, 

a collagen-based skin booster 

designed to directly replenish collagen within the skin.

Laetigen: A Different Approach from Conventional Skin Boosters

Laetigen is a skin booster treatment 

that delivers collagen directly into the skin 

to help improve both skin quality and structural support.

While many traditional treatments work by stimulating the skin 

to produce collagen indirectly, 

Laetigen takes a more direct approach 

by replenishing the components the skin needs.

What Does “Direct Collagen Replenishment” Mean?

Byun Kyung-hee et al., “Atelocollagen Increases Collagen Synthesis by Promoting Glycine Transporter 1 

in Aged Mouse Skin,” published in the International Journal of Molecular Sciences (IJMS)

A recent study 

published in the International Journal of Molecular Sciences (IJMS) 

investigated how atelocollagen functions within the skin.

The study found that 

when atelocollagen was injected into the skin, 

it promoted collagen synthesis, 

reduced oxidative stress, 

and improved both skin elasticity and collagen density.

Atelocollagen is a refined form of Type I collagen, 

the primary collagen found in human skin. 

During processing, 

unnecessary components that may trigger immune reactions are removed, 

allowing it to be applied more safely and stably within the skin.

Laetigen is a treatment 

that utilizes this type of atelocollagen. 

By delivering collagen directly into the skin, 

the treatment helps support and reinforce the skin’s underlying structure.

Type I Collagen: The Structural Foundation of the Skin

Collagen is not a single substance, 

but rather a family of different collagen types, 

each serving its own role within the body.

Among them, 

Type I collagen is especially important 

because it forms the majority of the dermal layer 

and plays a key role 

in maintaining skin structure, firmness, and density.

You can think of Type I collagen 

as part of the skin’s internal framework,

helping the skin maintain its shape 

and resilience from within.

As we age, 

this structural collagen gradually decreases. 

Over time, the skin becomes thinner, 

less elastic, and more prone to sagging and wrinkles.

Laetigen is designed to 

help address these changes 

by directly replenishing collagen 

and supporting the skin’s structural integrity.

"Areas Where Laetigen Can Be Applied"

Laetigen is particularly beneficial for areas 

where the skin is thin and where signs of aging 

tend to appear more easily.

Around the Eyes
The under-eye area has very delicate skin, 

making it especially prone to fine lines and creasing. 

By improving skin density and elasticity, 

Laetigen may help create a smoother and more refined appearance.

Forehead
The forehead is another area 

where repeated facial expressions can lead to fine lines over time. 

As overall skin quality improves, 

wrinkles may appear softer and less noticeable.

Nasolabial Folds and Around the Mouth
Areas around the mouth and smile lines 

can deepen as skin elasticity declines. 

Laetigen works by improving skin quality 

and supporting the surrounding tissue, 

helping create a naturally refreshed appearance.

------------------------

Laetigen is one of the treatments 

that aligns well with today’s preference 

for natural-looking results.

Rather than simply filling empty spaces, 

the treatment focuses on supporting 

and improving the skin’s underlying structure 

in a subtle and harmonious way.

For this reason, 

the goal of treatment should not be about creating dramatic changes, 

but about achieving results 

that naturally suit each individual’s features and skin condition.

If you are considering treatments 

for wrinkles or overall skin quality, 

we recommend taking the time 

to have a thorough consultation 

and finding the approach that best fits your skin and aesthetic goals.

Thank you.
