Korean Skin Boosters Explained: Rejuran, Juvelook and Lituo

Short answer: skin boosters are injectables placed in the dermis to improve skin quality rather than shape. Rejuran repairs and calms, Juvelook rebuilds collagen and texture, and Lituo supports the skin's matrix. Most people need 2–3 sessions, and they are often combined.

1. What a skin booster is, and what it is not

Fillers add volume to change contour. Boosters work at a finer level: they are injected as many tiny deposits across the face to improve hydration, elasticity, fine lines, pores and glow. The result is better skin, not a different face.

Korea has been the testing ground for many boosters because patients here prioritise skin quality, and Korean manufacturers develop products locally.

2. Rejuran: repair

Rejuran Healer uses polynucleotides (PN) purified from salmon DNA. PN supports tissue repair and reduces inflammation, so it suits sensitive, thin or damaged skin and recovery after lasers. Expect visible bumps for 1–3 days and a course of 3 sessions, 2–4 weeks apart. Rejuran details.

3. Juvelook: collagen and texture

Juvelook combines PDLLA microspheres with hyaluronic acid. PDLLA stimulates collagen gradually, improving shallow acne scars, texture and fine lines. Juvelook Volume is placed deeper for soft volume. Juvelook details.

4. Lituo: matrix support

Lituo is a newer booster aimed at reinforcing the extracellular matrix that holds collagen and elastin. Dr. Yang often uses it for thin, tired skin that has plateaued with other boosters. Lituo details.

5. Which one should you choose?

• Sensitive or damaged skin: Rejuran first
• Texture, pores, shallow scars: Juvelook
• Thin, tired skin: Lituo, often after Rejuran

6. Planning boosters around travel

Book boosters early in your trip so bumps settle before photos or flights. If you cannot stay for a full course, do one session per trip, or two sessions two weeks apart on a longer stay. Our Radiance Injection program sequences boosters for you.

Conclusion

Boosters are the Korean route to healthier, brighter skin. The right one depends on what your skin needs most: repair, collagen or support. Send photos for a personal recommendation.
