What is Lafullen?
Lafullen is an injectable collagen booster built on PCL (polycaprolactone), a biodegradable polymer that encourages your skin to produce its own collagen. Developed by Samyang Biopharm, it combines PCL microspheres with a CMC (carboxymethyl cellulose) gel carrier that delivers the particles evenly. It is designed to gradually refine skin texture and firmness, and at Seye Clinic it is available in two options: Lafullen 1 vial and Lafullen 3 vials.
How it works
Lafullen uses a porous microsphere structure that reduces particle clumping and increases the surface area in contact with your cells. Once injected, the PCL slowly breaks down over time and stimulates your own collagen production, while the gel carrier provides hydration and a subtle volume effect right after treatment. Because the newly formed collagen fills in texture and elasticity over the following weeks, results build up gradually across several sessions rather than from a single treatment.
Key benefits
- Stimulates your own collagen through its PCL component to help improve skin firmness.
- Delivers hydration and a subtle plumping effect from the gel carrier right after treatment.
- Helps smooth rough, uneven skin texture.
- The porous microsphere design lowers the risk of particle clumping for more even collagen remodeling.
- After 2-3 sessions at 4-week intervals, results last about 6-9 months (individual results may vary).
Recommended for
- Those who feel their skin has lost its former firmness
- Those who want to smooth rough, dull-looking skin texture
- Those who want to start collagen care without incisions or long downtime
- Those who prefer a natural, gradual anti-aging approach
- Those weighing Lafullen against boosters like Rejuran or Juvelook and unsure which collagen-stimulating method suits them
Lafullen at Seye Clinic
Before your Lafullen treatment, our medical team carefully checks your skin condition and the degree of elasticity loss, then honestly advises the dosage and injection areas you actually need. Rather than pushing extra vials, we prioritize a plan suited to your individual skin and take the time to explain aftercare and what to expect. Because a collagen booster is not completed in a single visit, our goal is to follow the changes and maintenance cycle session by session to build a natural result.
