In general, Karisma is quite safe because it uses Rh-Collagen, which is highly compatible with the body, together with HA, a substance the body is already familiar with, so the chance of irritation is low. The most common symptoms are mild swelling, redness, and bruising in the early days, which usually go away on their own. But there is one thing I want you to understand above all else — true safety doesn't lie in the substance alone, but in "who injects it, whether it's genuine, and whether they can assess properly." In this article, Dr. Time will walk you through what's normal, what to watch for, and how to prevent problems — without scaring you.
Is Karisma Dangerous — A Doctor's Straight Answer
"Doctor, is injecting collagen into the face like this dangerous?" is a question I hear often, and I understand this worry well — because it's about our face. Let me answer you straight — in general, Karisma is quite safe if done the right way and by a doctor.
The reason is that Karisma uses Rh-Collagen (recombinant collagen), designed to be highly compatible with the body, together with HA, a substance that already exists in our bodies, so the chance of the body rejecting it or being irritated is low. If you'd first like to know what Karisma is, try reading the "What Is Karisma" article alongside this one.
Why Rh-Collagen Is So Compatible With the Body
Got questions? Dr. Time offers personalized, honest consultations — no upselling.
Consult via WhatsAppRh-Collagen stands for recombinant collagen — collagen produced to have a structure close to the collagen in our own bodies, so it fits in well and has a low chance of triggering a foreign-body reaction. There is research studying Type III recombinant collagen for skin rejuvenation, which found it to be effective and to have acceptable safety when used appropriately.
This is the reason many people choose Karisma — they feel reassured by using a substance that is "close to natural." But I always emphasize that a good substance is only the starting point — how it's injected and who injects it matter just as much.
Symptoms That Are Perfectly Normal (and Usually Resolve on Their Own)
After getting Karisma, these symptoms can occur and are usually nothing to worry about. I want you to know about them in advance so you won't be alarmed.
- Mild swelling or redness at the injection site, during the first 2-3 days
- Mild bruising, especially if a tiny capillary is touched, which usually fades on its own within a few days
- A feeling of tightness or being able to feel the substance in the early period, before everything settles into place
These symptoms are the body's normal response to an injection, not a sign that something is wrong. Apply gentle cold compresses as I recommend and avoid pressing hard during the early period. Most of the time, things gradually improve on their own within a few days.
Warning Signs to Watch For and See a Doctor About
Although uncommon, I want you to know which symptoms are "not normal" and warrant coming back to see me promptly — not to make you afraid, but so you can take care of yourself in time.
Unusual, steadily increasing pain; spreading or hot swelling and redness; abnormal skin color changes (paleness or unusual darkening); a hard lump that doesn't subside; or any abnormal vision symptoms — these symptoms, though rare, warrant going back to see the doctor who treated you immediately if they occur. Don't wait and watch on your own.
| Symptom | Normal (Usually Resolves on Its Own) | See a Doctor Promptly |
|---|---|---|
| Swelling/redness | Mild, first 2-3 days | Spreading, hot, steadily increasing swelling |
| Pain | Mild tightness | Unusual, increasing pain |
| Bruising | Small spots, fade within 2-3 days | Unusual, spreading bruising |
| Skin | Normal | Color change (paleness/unusual darkening) |
The Real Risk — Not the Substance, but "Who Injects It"
This is the point I most want to emphasize, because it is the heart of safety — most of the danger of injecting substances into the face does not come from a good substance, but from injecting into the wrong layer, the wrong position, using a non-genuine product, or being injected by someone who isn't a doctor, especially in areas near blood vessels that require knowledge and care.
Having a doctor who takes your history, assesses the risks, chooses the injection position and layer with understanding, and then uses a genuine, verifiable product — that is what turns "injecting a substance" into "a safe treatment."
Who Should Avoid It / Consult First
Generally Suitable If You
- Are in good health with no contraindications
- Have no infection/rash on the skin in the area to be treated
- Fully disclose your allergy history and underlying conditions to the doctor
Consult First / May Need to Avoid
- Are pregnant or breastfeeding
- Have an infection or rash in the area to be injected
- Have a history of allergy to the ingredients
- Have certain immune conditions or underlying diseases
How to Prevent Side Effects
- Before the procedure — choose a genuine, FDA-approved product (check at oryor.com), get injected by a doctor who can assess properly, and fully disclose your allergy history/underlying conditions.
- Day 1 to 2-3 days — apply gentle cold compresses as the doctor recommends, and avoid pressing or massaging the injection area hard.
- The early period — avoid intense heat, saunas, steam rooms, and heavy exercise as the doctor recommends.
- If you have any abnormal symptoms — go back to see the doctor who treated you promptly; don't wait and watch on your own or buy medicine to self-treat.
- The substance Rh-Collagen + HA is highly compatible with the body, with a low chance of irritation
- Mild swelling, redness, and bruising in the early days is normal, but severe pain / spreading / color change = see a doctor promptly
- The real risk lies in "who injects it + whether it's genuine" — always choose a doctor + a genuine product

Frequently Asked Questions
The questions about Karisma's safety that patients ask me most often — I've gathered them to answer right here.
Is Karisma dangerous?
In general it's quite safe because Rh-Collagen is highly compatible with the body, but real safety depends on technique, a genuine product, and assessment by a doctor — not just the substance.
What are the side effects?
Mild swelling, redness, and bruising during the first 2-3 days, which usually resolve on their own. The things to watch for are severe pain, spreading swelling, heat, lumps, or skin color changes — you should see a doctor promptly.
Can you have an allergic reaction?
The chance is low because Rh-Collagen and HA are highly compatible with the body, but an individual reaction is possible. You should disclose your allergy history before the procedure.
How many days until the swelling goes down?
It usually improves on its own within 2-3 days; cold compresses help. If the swelling increases, spreads, becomes hot, or the pain is severe, consult a doctor promptly.
Why does who injects it matter?
Because most of the danger comes from injecting into the wrong layer/position, a non-genuine product, or an injector who isn't a doctor. Having a doctor assess and inject themselves keeps the risk under control.
Who should not have it done?
People who are pregnant/breastfeeding, have an infection in the area to be injected, are allergic to the ingredients, or have certain underlying conditions should consult a doctor first.
How do you prevent side effects?
Choose a genuine product, get injected by a doctor, disclose your history fully, take care of yourself after the procedure, and come to your follow-up appointments.
Is it FDA-approved, and how do I check?
It is referenced as having a CE Mark and registration in certain countries, including Thailand. You can ask to see the box/registration number and check it yourself at oryor.com.
