LAETIGEN
A collagen injection that directly replenishes atelocollagen in the skin to refine fine lines and skin texture
ABOUT
What is LAETIGEN?
- 01
LAETIGEN contains pure Type I atelocollagen with immune-response-triggering substances (telopeptides) removed, immediately replenishing the underlying structure of the dermis.
- 02
Unlike PLA- and PCL-based products that stimulate collagen production, it directly injects highly purified collagen to rebuild the dermis and subcutaneous fat.
- 03
Unlike PLA- and PCL-based products that stimulate collagen production, it directly injects highly purified collagen to rebuild the dermis and subcutaneous fat.
HOW IT WORKS
How does it work?
It rebuilds the skin's underlying structure by directly replenishing Type I collagen lost from the dermis through aging.
LAETIGEN promotes structural stabilization by directly injecting Type I collagen, which accounts for approximately 90% of the skin's dermis.
WHERE IT WORKS
0 ~ 0.1mm
Epidermis
0.1 ~ 3.0mm
Dermis
(Primary target)
3.0mm or deeper
Subcutaneous tissue
Strengthens supporting structures and helps the effects of dermal reconstruction last longer
RECOMMENDED FOR
Who is it for?
- 01
When collagen loss in the dermis is accompanied by fine surface lines and dry skin
- 02
When immediate, direct injection of collagen is needed rather than a collagen-stimulating booster
- 03
When aging has thinned the dermis and reduced skin density and firmness
- 04
When treating thin-skinned areas prone to fine lines, such as around the eyes and mouth or on the neck
TREATMENT AREAS

BENEFITS
Changes you can expect
- 01Smoother fine lines and skin texture
- 02Support for skin firmness and density
- 03Improved condition of skin that looks dry and thin
- 04Support for the skin's structure through the direct use of collagen
KEY POINTS
Key treatment points
- 01Delivers Type I atelocollagen directly into the skin
- 02A direct supplementation approach that differs from products that stimulate collagen production
- 03Used when fine lines, skin texture, and density are concerns together
RESULT JOURNEY
How things change over time
Injection marks or small raised bumps may be visible immediately after treatment.
Once swelling subsides, skin hydration and texture improve first.
Depending on the product and skin condition, firmness and density can be expected to improve naturally over several weeks.
INEE APPROACH
How INEE approaches this treatment
- 01
We first assess the current skin condition rather than applying one product in the same way to every skin type.
- 02
We prioritize hydration, texture, firmness, and density to plan the product and injection areas.
- 03
When other treatments are considered together, we adjust their order and intervals according to skin recovery.
RECOVERY & CARE
What to check before and after treatment
Before treatment
Please tell us during consultation about previous treatments involving collagen or animal-derived ingredients. If you have an important event, schedule treatment with time for bruising and swelling to resolve.
Immediately after & recovery
Injection marks, redness, and small raised bumps may appear and generally settle within a few days. Bruising may be visible in areas with thin skin.
Aftercare
On the day of treatment, avoid pressing firmly on the skin, saunas, alcohol, and strenuous exercise. Keep the skin well moisturized and protected from the sun.
