Juvelook (Skin Booster Injections) are performed at Mona Aoyama Clinic in Minami-Aoyama.
From ¥9,500 (tax included) / Open daily, 5-minute walk from Aoyama-Itchome Station.
What is Juvelook?
Juvelook is a skin regeneration injection containing poly-D-L-lactic acid (PDLLA) and hyaluronic acid. The injected polylactic acid stimulates fibroblasts, promoting the production of collagen and elastin, thereby improving skin firmness, elasticity, and radiance from within.
Developed in Korea, it differs from immediate-acting hyaluronic acid fillers in its characteristic fundamental approach to nurturing the skin itself.
Expected Effects of Juvelook
- Improved skin firmness and elasticity
- Reduced appearance of pores
- Improved fine lines and crepey wrinkles
- Improved skin dullness and transparency
- Uniform skin quality and texture
Effects vary from person to person.
Recommended for those who:
- Are concerned about skin firmness and elasticity
- Are concerned about open pores or rough skin texture
- Are concerned about fine lines and crepey wrinkles
- Want to fundamentally change their skin quality, which is difficult to improve with hyaluronic acid
- Want to engage in anti-aging treatments
Mechanism of Action of Juvelook
Collagen Production by Polylactic Acid (PDLLA)
The main component of Juvelook, poly-D-L-lactic acid (PDLLA), stimulates fibroblasts in the skin after injection, promoting the natural production of collagen and elastin. The generated collagen forms a structure that supports skin firmness and elasticity, lifting the skin from within.
Synergistic Effect with Hyaluronic Acid
Juvelook also contains hyaluronic acid, which provides immediate moisturizing effects. Combined with the long-term collagen production effect of polylactic acid, both initial changes and sustained effects can be expected.
Progression to Visible Effects
| Timing | Condition |
|---|---|
| Immediately after treatment ~ 1 week | Mild swelling and redness at the injection site begin to subside |
| 1-2 months later | Collagen production progresses, and improvements in firmness and elasticity begin to be felt |
| 3-6 months later | Maximum effect. Significant improvements in skin quality, pores, and fine lines |
| 6 months ~ 1 year or more | Effects persist. Regular additional treatments for further maintenance and improvement |
Unlike immediate-acting hyaluronic acid, collagen production takes time. Many people begin to notice changes after 1-2 months, and the full effect is generally seen 3-6 months after the final treatment.
Difference from Rejuran
Injections aimed at skin regeneration include Rejuran in addition to Juvelook. Since their main ingredients and areas of expertise differ, the choice depends on your concerns.
| Juvelook | Rejuran | |
|---|---|---|
| Main ingredient | Polylactic acid (PDLLA) + hyaluronic acid | Salmon-derived polynucleotide (PN) |
| How it works | Stimulates fibroblasts to increase collagen | Promotes skin regeneration and repair, reduces inflammation |
| Area of expertise | Pores, skin firmness and elasticity, overall skin quality improvement | Dryness, rough skin, fine lines, thin skin around the eyes |
| Onset of effects | Appears gradually and lasts long | Relatively quick to feel skin hydration |
Which is more suitable depends on your skin condition, and sometimes a combination of both is used. For more details, please refer to the Rejuran page.
We will suggest a treatment plan tailored to your skin condition.
