Juvelook is a skin booster that places poly-D,L-lactic acid (PDLLA) and hyaluronic acid from one vial into the skin. Immediately after injection, hydration fills in, and over the following weeks the procedure is watched for whether new collagen forms.
The vial contains PDLLA and hyaluronic acid. In one preliminary study, half of those treated answered that they had improved by more than half overall. It is an injection of reconstituted powder into the dermis, so the time you wait for change differs from a filler that is finished on the day.
What kind of injection Juvelook is
Dried powder is mixed with saline or similar and placed in the dermis. Hyaluronic acid fills hydration right away, and PDLLA is a material expected to settle, then slowly break down while new collagen is formed. Its role differs from a filler that only adds volume.
One preliminary study injected this product into the face, but mixed extra hyaluronic acid and anesthetic into the vial. That mixing ratio is not necessarily the same as what you receive in clinic. In tissue from people who consented, collagen and elastic fibers were observed to have increased, and the tally of serious adverse events was 0.
Products under the same name are placed in different layers, so which product is being used is confirmed before consultation. There is also a separate product presented for the eye area. The manufacturer presents it as a medical device authorized in Korea.

The ingredients differ from Rejuran and glow injection, so what fits your skin is distinguished first by ingredient. If more comparison is needed, continue with the Rejuran vs Juvelook comparison.

The treatment day and the week after
In consultation, skin thickness and previous injection history are reviewed, then sites are chosen; numbing cream is applied, and small amounts are placed. One preliminary study gave 2–3 sessions at 4-week intervals. Right afterward, swelling, redness, and bruising are common, and injection marks may remain as small dots for 1–2 days. On touch it may briefly feel tight or uneven. After it is finished, aftercare is confirmed and you go home.
On the first day, avoid intense heat and vigorous cleansing, and do not press or rub the injection sites hard. Light makeup is started while watching the skin, and for 1 week saunas, jjimjilbang, and vigorous exercise are reduced while sun protection is maintained. Alcohol and smoking can slow recovery, so they are reduced for several days. Cost varies with dose and session count; what changes the price can be seen in the cost information. The treatment page is the Juvelook treatment information.
Five things to confirm in consultation
If a facial injection enters a blood vessel, vision may blur or the skin may turn white or bluish. An overseas regulatory agency lists these signs as needing immediate medical care in general guidance on injectable fillers. Palpable nodules are a known reaction in this class, so where to call is decided in advance. If fever develops or hives spread widely, an allergic reaction is suspected and medical care is sought immediately.
- □ Whether today's product is Juvelook or Juvelook Volume
- □ How many sessions, and at how many weeks' interval
- □ Pregnancy and breastfeeding, infection at the treatment site, anticoagulants and immunosuppressants, autoimmune disease, allergy to anesthetic or ingredients
- □ Interval from previously placed filler or skin booster
- □ Where to call if a nodule is felt or vision or skin color changes
If swelling still grows after 2 days, fever develops, or a firm area enlarges, contact the place where you were treated. If nodules are a concern, read the nodule information after injection; for shared cautions, see the treatment safety information.
Frequently asked questions
Q1. Does it hurt?
The treated site may feel tight or sting, and injection marks and light bruising tend to settle within a few days. The degree of pain varies with the site and the amount placed.
Q2. How many sessions?
The schedule used in research is 2–3 sessions, 4 weeks apart. The actual number is set in consultation based on skin condition, goals, and site.
Q3. How long do the effects last?
The manufacturer presents 12 to 18 months. What a preliminary human study looked at was change immediately after treatment and at visit time points.
Q4. Can it be combined with other procedures?
Stacking several injections on the same day stacks swelling and bruising. With lasers, thread lifting, and other skin boosters, interval and order are set separately. Bringing a list of current procedures and medicines speeds coordination.
Q5. Who should not receive it?
People who are pregnant or breastfeeding were also excluded from the preliminary study. If there is infection or inflammation at the treatment site, or allergy to the ingredient or anesthetic, the schedule is postponed. Use of anticoagulants or immunosuppressants is also disclosed in advance.
Results, duration, and suitability vary with individual skin condition, age, and lifestyle, and the same outcome cannot be guaranteed.
Procedures may cause temporary redness or swelling, and contraindications may apply, so please confirm these during your consultation.
