The nose and the under-eye area are among the filler sites with an especially dense network of blood vessels. Small vessels run closely through both areas, and an incorrect injection depth or direction can lead to vessel compression or embolism. For this reason, nose filler and under-eye filler are not "small, simple treatments"; they are areas where the anatomy needs to be understood before treatment. This article explains the main precautions for each area.
Nose Filler: The Area with the Highest Risk of Vascular Embolism
The nose is known as the filler site with the highest risk of vision loss and tissue necrosis. Blood vessels inside the nose connect with the retinal vessels of the eye, so if filler enters a vessel, it can lead to vision damage. This pathway is especially risky at the upper bridge of the nose, next to the glabella, rather than at the tip, and even a slight error in injection pressure or angle can result in an intravascular injection.
Before nose filler, it is generally advisable to confirm that the practitioner understands the vessel distribution. Injecting slowly in small amounts, checking by aspiration before injecting, and whether a cannula is used are key technical factors that determine safety. For nose filler, Repic Clinic in Gangnam uses only officially imported KFDA-approved products and keeps hyaluronidase (a filler-dissolving agent) on hand at all times in case of emergency.
Medications taken before the procedure also need to be reviewed. Aspirin, ibuprofen, omega-3 and vitamin E inhibit blood clotting, so stopping them 1 to 2 weeks before treatment is generally recommended. Alcohol also dilates blood vessels and should be avoided the day before treatment; these guidelines apply not only to nose filler but equally to under-eye filler.
Under-Eye Filler: Bruising, Swelling and the Tyndall Effect
The skin under the eyes is thin and the blood vessels lie close to the surface, so bruising and swelling after treatment can last relatively longer. Most bruises are absorbed within 1 to 2 weeks, but they can take longer depending on a person's vascular condition and the medications they take. With this in mind, it is recommended to have treatment at least 2 weeks before any important event.
Another problem that can occur with under-eye filler is the "Tyndall effect." If hyaluronic acid filler is placed in a layer of skin that is too shallow, light scatters and the area can look bluish or grayish. This can sometimes appear not within a few days but several months after treatment, so the practitioner's judgment of injection depth directly affects the result. It can be dissolved with hyaluronidase, but performing the treatment at the correct depth from the start comes first.
After treatment, you are advised not to press or massage the area firmly, and it is best to avoid saunas, steam rooms and strenuous exercise on the day of treatment and the following day.
Four Things to Check Before a Safe Treatment
A considerable share of filler side effects comes from the injection method rather than the product itself. Because both nose filler and under-eye filler are classified as higher-risk areas, it helps to check the following four points yourself before treatment. First, whether the filler is an officially imported KFDA-approved product that can be verified by the box and sticker. Second, whether you are given an explanation that takes vessel distribution into account before the procedure. Third, whether the clinic keeps hyaluronidase for emergency treatment on hand at all times. Fourth, whether the practitioner is a licensed medical professional. These four criteria are the same ones Repic Clinic in Gangnam applies in its actual treatment practice.

- No alcohol or strenuous exercise on the day of treatment, and no strong pressure on the treated area
- If you notice abnormal pain, skin color changes or vision problems within a few days after treatment, visit the clinic immediately
The precautions for nose filler and under-eye filler are not simply a matter of "a few days of recovery." Safer results can be expected only when vessel anatomy, product authenticity and the emergency response system are all checked together.
