“Injectable treatment” is an umbrella covering 4 main families, dermal fillers, skin boosters, collagen biostimulators, and muscle-relaxing toxin, each matched to a different goal.
Injectable treatment is an umbrella term for non-surgical injections that restore volume, hydrate, stimulate collagen, or relax muscles. The 4 main families are dermal fillers, skin boosters, collagen biostimulators, and toxin. At our Gangnam (Seoul) location, Dr. Yoongon Ryu selects the right type at consultation based on your goal, anatomy, and timeline.
One-on-One guidance from a dedicated doctor, ensuring your skin is professionally monitored and treated from start to finish.
Fluent assistance in English, Japanese, and Chinese, making communication clear, respectful and comfortable for international patients.
Over 100,000 patients worldwide have received our personalized dermatological care, highlighting our expertise and reliable results.
Injectable treatment is a broad category of non-surgical procedures that deliver a product into or under the skin through a fine needle or cannula, rather than cutting or lifting tissue. Because it is an umbrella term, “injectable treatment” is not one procedure but a family of them, and the right choice depends entirely on whether you want to add volume, improve skin quality, build your own collagen, or soften dynamic wrinkles.
The 4 main families are: dermal fillers (usually hyaluronic acid) that instantly restore volume and contour; skin boosters that micro-inject hydrating and revitalising ingredients across a wider area for glow and texture; collagen biostimulators such as PLLA and PDLLA that trigger your body to gradually produce its own collagen; and botulinum toxin, which temporarily relaxes specific muscles to soften expression lines. Each works by a different mechanism and follows a different timeline.
At our Gangnam (Seoul) location, injectable care is consultation-led. Dr. Yoongon Ryu and the clinic’s doctors assess your anatomy, skin, and goals, then recommend a single injectable or a combination. International patients receive full English-language support, and Gangnam is roughly 2 minutes from Gangnam Station exit 10 in Seoul, Korea.
Each injectable family solves a different problem, which is why one page cannot be reduced to a single technique. Dermal fillers, most commonly hyaluronic acid, physically occupy space in the tissue to lift folds, define contour, and replace age-related volume loss, with visible results on day 1. Skin boosters micro-inject hydrating agents such as hyaluronic acid or polynucleotides across the surface layers, improving hydration, fine lines, and glow over about 2 to 3 sessions rather than adding contour. Collagen biostimulators like poly-L-lactic acid (PLLA) and poly-D,L-lactic acid (PDLLA) are different again: instead of filling, they act as a scaffold that prompts fibroblasts to lay down new collagen, so results build gradually over roughly 2 to 3 months and can last well beyond a year. Botulinum toxin type A works on muscle rather than volume, blocking the nerve signal to targeted muscles so dynamic lines from frowning or squinting soften for about 3 to 4 months. Because these mechanisms differ, matching the injectable to the goal, and often combining two, is the core of a good plan, decided at consultation not from a menu.

Dr. Yoongon Ryu identifies which of the 4 families fits your goal, volume, glow, collagen, or line-softening, since each uses a different mechanism.
Injection points and depth are planned to your facial structure, because the same product placed at 2 different depths behaves differently.
Topical numbing is applied for about 15 to 20 minutes so most injectable sessions feel like brief pinches rather than pain.
The product is placed with a fine needle or cannula; a typical session takes 15 to 45 minutes depending on the family and area treated.
Fillers show on day 1, toxin over 3 to 7 days, boosters over 2 to 3 sessions, and biostimulators over roughly 2 to 3 months.
A follow-up around 2 weeks lets the doctor assess response and top up if needed, especially for toxin and biostimulator plans.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
Dr. Yoongon Ryu assesses your goals and anatomy, then recommends which of the 4 injectable families, or which combination, fits, in English.
After numbing for about 15 to 20 minutes, the session itself typically takes 15 to 45 minutes depending on the injectable and areas.
Toxin and single-area filler are quick; biostimulator courses run as 2 to 3 sessions spaced several weeks apart.
Fillers show immediately, toxin over 3 to 7 days, boosters over a short series, and biostimulators over roughly 2 to 3 months.
Results are maintained with repeat sessions; the doctor advises on massage, sun care, and timing based on the injectable used.
Injectable treatment is an umbrella term for 4 families of non-surgical injections: dermal fillers, skin boosters, collagen biostimulators, and botulinum toxin. Each uses a different mechanism, so the right one depends on your goal. Explore the options on our injection treatment page.
The right injectable depends on your goal: fillers for volume, boosters for glow, biostimulators for gradual collagen, and toxin for expression lines. Many patients combine two. At consultation, the clinic’s doctors assess your anatomy and priorities before recommending a single injectable or a tailored combination.
Dermal fillers add volume instantly by occupying space in the tissue, while collagen biostimulators such as PLLA prompt your body to make its own collagen over roughly 2 to 3 months. Fillers give day-1 results; biostimulators build gradually and can last longer. See our Juvelook Volume page for a biostimulator example.
Most injectable treatments cause only mild discomfort, described as brief pinches or pressure, and topical numbing is applied for about 15 to 20 minutes beforehand. Many fillers also contain lidocaine. Toxin injections use very fine needles and are typically the most comfortable of the families.
Downtime is usually minimal, with most patients returning to normal activity the same day. Temporary redness, mild swelling, or small bruises can occur and typically settle within a few days. Biostimulator aftercare includes gentle massage, which the doctor explains during your appointment.
Longevity varies by family: hyaluronic-acid fillers often last around a year, botulinum toxin about 3 to 4 months, and collagen biostimulators can last well beyond a year. Skin boosters are maintained with periodic sessions. None is a one-time fix, so repeat treatments sustain results.
It depends on the injectable: single-area filler or toxin is often one session, while biostimulators and skin boosters usually run as a course of 2 to 3 sessions spaced several weeks apart. Your doctor confirms the number after assessing your goal and how your skin responds.
Yes, combining injectables is common and often gives the most balanced result, for example toxin for lines plus filler for contour, or a biostimulator for firming. The clinic’s doctors sequence combinations safely so areas are not over-treated. You can review individual options on our Juvelook page.
Injectables have a high overall safety profile when performed by trained doctors, with side effects usually mild, transient, and self-limiting. Rare vascular complications make injector skill and anatomy knowledge essential. A thorough consultation and honest screening reduce risk, which is why care here is doctor-led, not menu-based.
Common side effects are temporary redness, swelling, tenderness, or small bruises at the injection site. Biostimulators carry a low risk of nodules, reduced by correct reconstitution and technique. Serious complications are rare. Your doctor reviews your history and explains warning signs before any injectable is placed.
A collagen biostimulator, such as poly-L-lactic acid (PLLA) or poly-D,L-lactic acid (PDLLA), is an injectable that prompts your own fibroblasts to produce new collagen rather than simply filling space. Results build over roughly 2 to 3 months. Learn more on our Juvelook Volume page.
Yes, skin boosters are an injectable family that micro-injects hydrating ingredients like hyaluronic acid or polynucleotides across the skin to improve glow and texture, rather than adding contour. They usually run as a short series. See our Rejuran Healer page for one example.
Yes, botulinum toxin type A is one of the 4 injectable families, but it works on muscle rather than volume, relaxing targeted muscles to soften dynamic lines for about 3 to 4 months. It complements fillers well. You can read more on our botox injection page.
Aftercare depends on the injectable but generally means avoiding heat, alcohol, and vigorous exercise for a day or two, and not rubbing the area after toxin. Biostimulators may need gentle massage. Sun protection helps in all cases. Your doctor gives written aftercare specific to your treatment.
Injectable treatment is available at our Gangnam (Seoul) location, roughly 2 minutes from Gangnam Station exit 10, with Dr. Yoongon Ryu and full English support. Reberry Clinic also has Myeongdong and Incheon Airport locations. You can plan a visit via our injection treatment page.
For most single injectable sessions, 2 to 3 days in Seoul is comfortable, allowing a consultation, the procedure, and a short review. If you want a biostimulator course or combination plan, your doctor helps coordinate return visits or remote follow-up around your travel schedule.
Yes, flying within a day or so is generally fine after most injectables, which are non-surgical. Cabin air is drying, so moisturise and protect skin from sun. Avoid strenuous activity briefly. If you had filler or biostimulator, your doctor advises on any swelling before travel.
International patients can complete single injectables in one visit, while biostimulator or combination plans may span return trips, with English-language remote check-ins between visits. Your treatment notes are kept on file for continuity, and the team helps schedule any top-ups around your next trip to Seoul.
