Laetigen Collagen
LIJIN’s Laetigen Collagen
Stimulate Youthful Collagen Production and Restore Volume
with Laetigen Collagen
Laetigen Collagen strengthens the skin’s foundation by stimulating collagen renewal, targeting early signs of aging such as fine lines and loss of firmness, while also supporting long-term elasticity and natural contour restoration.
Laetigen Collagen
What is Laetigen Collagen?
This functional skin booster directly replenishes Type 1 collagen in the skin, enhancing elasticity and density.
What are the Benefits?
- Restores skin firmness and density
- Improves fine lines, enlarged pores, and skin laxity
- Supports natural contour restoration with long-lasting results
Proof of Regeneration: Restoring Dermal Density
Laetigen creates an optimal environment (ECM) for skin cells. Unlike simple fillers, it provides pure collagen directly to the dermis.
This not only reinforces the skin's structure immediately but also awakens dormant fibroblasts,
triggering them to produce new, healthy collagen networks naturally.

Collagen-Depleted Environment
In aging skin, collagen fibers are sparse and disconnected (marked by).
The fibroblast (N) appears inactive and isolated due to the lack of structural support,
leading to wrinkles and loss of elasticity.

Densified Collagen Network
After Laetigen treatment, the dermis is packed with dense, newly formed collagen fibers (arrows).
The fibroblast is reactivated, firmly attaching to the collagen matrix and continuously regenerating the skin from within.

Skin Restoration with Laetigen
Laetigen is a skin booster designed to restore the skin’s balance by replenishing essential components, with a key focus on collagen support.
By compensating for age-related collagen loss, it helps improve elasticity, dryness, and fine wrinkles—
promoting healthier, more resilient skin.

Collagen for Moisture Retention
Collagen helps bind moisture within the skin, filling the spaces between cells and preventing the loss of hydration and nutrients. This supports a smoother, well-moisturized skin condition.

Glycine for Structural Firmness
Glycine is an essential amino acid that stabilizes the triple-helix structure of collagen, helping maintain firm, smooth, and radiant skin. It plays a key role in supporting overall skin elasticity.

Collagen Peptides for Dermal Renewal
The collagen peptides in Laetigen share a structure similar to the skin’s own collagen, allowing them to be readily used during tissue regeneration. They support recovery, firmness, and overall skin resilience.
Recommended for
For individuals experiencing dryness, dullness, and a weakened skin barrier.
For those noticing diminished radiance, tired-looking skin, and reduced elasticity.
For skin compromised by stress, pollution, UV exposure, or external irritation.
Cautions
If you recently had fillers, lasers, RF, microneedling, or other regenerative procedures, spacing may be required.
Mild swelling, redness, or small bruises are normal and typically subside within 2–3 days.
Do not rub or press the treated area; light cleansing and makeup are allowed after 4–6 hours.
Temporary unevenness may occur as collagen settles and usually improves naturally.
Collagen takes time to integrate, so improvements in texture and firmness appear gradually over 1–2 weeks.
FAQ
A. Laetigen Collagen focuses on stimulating collagen production to restore firmness and density in the skin. Patients often notice a subtle lifting effect and smoother skin texture within a few weeks. Over the following months, collagen remodeling continues, leading to visible improvements in elasticity, fine lines, and overall skin resilience.
A. For the best outcome, we usually suggest 3–5 sessions spaced about 3–4 weeks apart. This allows enough time for collagen remodeling and cumulative improvement in skin quality. Maintenance sessions every 9–12 months can help prolong results and keep the skin firm and youthful.
A. Yes. At LIJIN, we use clinically tested protocols and medical-grade techniques to ensure safety and comfort. Laetigen Collagen is most suitable for patients noticing reduced elasticity, fine lines, or early sagging. It is also recommended for those who prefer a natural, gradual improvement in skin firmness rather than an immediate but short-term effect. Each plan is customized to match individual needs and skin conditions.
