If the Rejuran Injection Site Feels Bumpy

You come home after the procedure and wash your face, or a few days later, you feel something at your fingertips while applying lotion. It is not very visible to the eye, but when touched, something small and hard is felt.

At Secret Clinic, we often receive this question the day after the procedure. If you search for this condition, you will see a mix of posts saying "it's okay" and "you must go to the hospital." Both are correct, but the lack of clarity on which one applies to your case only increases anxiety. Let's clarify that boundary.

First, this is a reaction listed in the approved instructions

The official Rejuran manual lists possible reactions. The list includes **"injection site nodules or induration."** Nodules refer to lumps, and induration refers to hardening.

The same document also lists inflammatory reactions. It states that redness, swelling, and erythema may occur along with itching or pain, and these reactions can last for about a week.

Knowing these two points gives you a baseline. The fact that something is felt is not unexpected, and redness and swelling lasting for about a week is within the range stated in the document.

However, being listed does not mean everything is okay. If you have the following signals, you should seek medical attention regardless of the duration.

Bumps immediately after the procedure and lumps a few days later are different stories

You may have heard of Rejuran Embo. Since the method involves injecting small amounts into multiple points rather than spreading it widely at once, small bumps appear in rows on the skin immediately after the procedure.

This is not a reaction, but the liquid itself that was just injected. Since liquid has entered the skin, volume has been created, and it usually flattens within a day to a few days as it is absorbed.

Therefore, you must distinguish between the bumps seen immediately after the procedure and the lumps that remain and are felt after they have subsided. The former is the shape of the procedure, and the latter is the nodule discussed in this article.

Why is it felt?

The degree to which it is felt from the surface varies depending on the depth at which the injected substance is placed in the skin. Even with the same amount, if it is closer to the surface, it is more easily caught by the fingertips; if it is deeper, it is felt less. It is a matter of location, not a special principle.

Added to this is the reaction of the surrounding tissue. The body reacts to new substances, and in the process, the surrounding area can temporarily become hard. The reason nodules and induration are listed side-by-side in official documents is that these two often appear together.

Many people say it is more noticeable in areas with thin skin, such as under the eyes. This is because if the covering tissue is thin, the same object is felt more closely.

However, the official manual does not specify standards for injection depth. The depth is determined by the performing doctor based on the area and condition.

Cases where you can observe and cases where medical attention is needed

This is the most important part. You can categorize them as follows.

Cases where you can monitor the progress

· It is felt when touched but not very visible externally
· It is felt slightly when pressed but does not hurt when left alone
· The color has not changed and there is no heat sensation
· It gradually gets smaller over time or stays the same

Cases where you must seek medical attention regardless of the duration

· Redness, heat, or pain worsens over time
· The lump gradually grows larger
· It hurts even without being pressed
· Skin color changes, especially turning white or purplish
· Pus forms or a fever occurs
· Inflammatory reactions do not subside after a week
· The lump remains the same after several weeks

The items below may not be simple progress but other issues, so they must be judged by direct observation. In particular, if there is a change in color or severe pain, you must contact us immediately. At Secret Clinic, we advise patients to let us know if such changes occur after the procedure, regardless of the time elapsed.

Things you should avoid doing in the meantime

When worried, you tend to touch it, but a few things can prolong the condition.

· Trying to dissolve it by rubbing or pressing hard
· Trying to squeeze it with a needle or fingernail
· Trying to "melt" it with hot compresses or saunas
· Applying or taking medication based on self-judgment
· Receiving other procedures in the same spot while the lump remains

Rubbing can change the shape, making it easy to feel like it's effective, but added irritation can prolong redness. If you are curious, instead of searching for skin booster side effects alone, it is faster to take a photo and send it to the place where you received the procedure.

Things you must mention before the next procedure

Injection nodules are influenced by conditions, not just luck. The official manual lists cases where this product should not be used or used with caution.

· If you have received fillers that are not absorbed by the body
· If you are taking anticoagulants or immunosuppressants
· If you have an autoimmune disease
· If you have had a hypersensitivity reaction to the product ingredients
· If you are pregnant or breastfeeding
· If the skin at the procedure site is damaged

Asking these items during a Rejuran consultation in Gangnam is not a formal procedure. If you had an experience where nodules lasted a long time last time, it is good to mention that as well. Whether to do it again in the same area and in the same way, or whether to adjust the amount or interval, will change.

In Summary

Feeling the area where Rejuran was injected is a reaction listed in official documents, and it is stated that inflammatory reactions can last for about a week. This is within the expected range.

The boundary is the direction. If it is moving toward subsiding over time, you can monitor it; if it worsens, grows, or changes color, you must show it to us regardless of the duration.

And the first thing to do when you are worried is not to touch it yourself, but to ask the place where you received the procedure. If you had the procedure at Secret Clinic, you can contact us at your convenience. Most cases are resolved with a single photo.
