Collagen Skin Booster · Mellow Dermatology (Yeongdeungpo)
Not filling it in —
letting your skin rebuild itself
A skin booster delivers active ingredients directly into the dermis to revive the environment beneath your skin. Discover Mellow's collagen skin booster with Juvelook, a PDLLA collagen-stimulating formula that restores firmness, texture and moisture from within.
Skin Booster
As we age, the skin
can no longer make it on its own

As years and UV exposure accumulate, the collagen and regenerative power of the dermis decline. Firmness fades, texture grows rough, and even minor irritation turns the skin red.
A skin booster is the evolved form of the skin-brightening (water-shine) injection, delivering active ingredients directly into the dermis to improve the environment beneath the skin. Rather than filling the surface, it revives the foundation that lets your skin rebuild itself.
How It Works
Juvelook works in
two ways at once
Juvelook combines PDLLA and hyaluronic acid, so it delivers both immediate hydration and collagen regeneration over time — a collagen-stimulating booster in a single treatment.
PDLLA · Collagen
Prompts your skin to make collagen
PDLLA microparticles break down gradually in the dermis, stimulating collagen production. Over time, firmness and skin texture improve from within.
Hyaluronic Acid
Instant moisture & volume
The hyaluronic acid it contains fills the skin with moisture and volume from the very first injection, adding an immediate boost of hydration and glow.
Effects
Four changes that build
up from within
It begins with immediate hydration, and over one to two months collagen builds up as natural changes continue to unfold.
Elasticity
Improved firmness
As collagen forms, the skin builds up from within and firmness returns.
Texture
Texture & moisture
Rough, dry texture becomes smooth and hydrated from deep within.
Volume
Restored volume
Naturally refills lost volume, adding vitality back to the face.
Fine Lines
Fine lines & lifting
Softens fine lines around the eyes and nasolabial folds, with a subtle lifting effect.
Boosters
Choose the booster
that fits your skin concern
Collagen stimulation, regeneration, volume, moisture — each booster fills a different need. We combine them to match your skin's condition and improve it from within.

Expert Care
With boosters, 'how it's
injected' matters more than the ingredient
Dr. Kwon Hyung-il, Director · Board-certified dermatologist
Even a good booster can leave nodules or side effects if injected at the wrong depth. What matters more than the ingredient is which layer it goes into, and at what concentration.
Choosing the right booster for the skin's condition and area, and adjusting depth and concentration — natural results come from that precision. From diagnosis to treatment, the specialist handles it personally.
★ Mellow collagen booster principles
- Customized booster type and concentration for each skin condition
- Precise-depth injection to minimize nodules and side effects
- Immediate hydration + collagen regeneration over time, together
Before & After Care
With boosters, 'how it's
injected' matters more than the ingredient
Incorrect depth or excessive concentration can leave side effects related to nodules, pigmentation or blood vessels. In particular, products containing hyaluronic acid carry a risk of vascular occlusion, so precise treatment is essential. After the procedure, avoid irritation and keep up with hydration and sun protection; changes usually appear naturally over one to two months.
