Skin Booster Pain, How Much Does It Hurt? An Honest Guide on Products, Target Areas, and Anesthesia

Skin booster pain is generally tolerable. When performed after applying anesthetic cream, the pain is commonly reported to be around 3 to 7 on the Visual Analogue Scale (VAS/NRS 0–10), but individual variation is significant. Understanding that it is not a single needle prick, but a repeated stimulus of dozens to hundreds of micro-injections into the dermis layer, makes preparation much easier.

Why does it hurt? Skin boosters are treatments in which ingredients like hyaluronic acid, polynucleotide (PN/PDRN), and polylactic acid (PLLA) are injected into the dermis at multiple points. Because nerve endings are densely concentrated in the dermis layer, the pressure pain from the tissue expanding as the drug enters is often felt more intensely than the needle puncture itself. On top of this, product viscosity, ingredient characteristics, the treated area, and your physical condition on that day can make the perceived pain vary.

💉 Why Does Skin Booster Pain Happen?

The cause of pain is not just one thing. Three major factors overlap.

• Physical stimulus: If it's a full-face treatment, dozens to hundreds of micro-injections are made. The number of punctures itself is quite high.

• Pressure and expansion: The feeling of the drug pushing against the tissue as it enters the dermis. This is the source of the 'throbbing' sensation.

• Ingredient irritation: Polynucleotide-based products are directly linked to stinging and burning, while hyaluronic acid differs in its sensation of expansion depending on its viscosity.

The depth of injection also plays a role. It enters at approximately 0.5 to 2 mm, and the shallower the dermis layer, the greater the nerve stimulation, which can lead to stronger stinging. The needles used are usually 30 to 34G; the higher the number, the thinner the needle, resulting in relatively less puncture pain.

📌 Key Summary: Skin booster pain is caused by a combination of repeated punctures, injection pressure, and ingredient irritation, with the nerve density in the dermis layer being the fundamental cause.

📊 How Much Does Pain Differ by Product?

Since ingredients and viscosity vary by product, the perceived pain also differs. However, the following is just a trend and not an absolute ranking. An individual's pain threshold and differences in the treated area play a larger role than the numbers.

The key point is whether it contains lidocaine. Products mixed with lidocaine (e.g., Rejuran HB plus) significantly reduce perceived pain during and after the procedure compared to products in the same line without lidocaine. If you are sensitive to pain, checking if there is a lidocaine-containing option provides practical help.

Let's clear up one misconception. More pain does not mean better results. Pain intensity and treatment outcomes are not proportional. The belief that more pain yields better results is a groundless myth.

📌 Key Summary: Rejuran products tend to sting, Juvelook is moderate, and HA products focus on the feeling of expansion. Products containing lidocaine are advantageous for pain relief.

🗺️ Which Area Hurts the Most?

Even for the same treatment, the pain varies greatly depending on the area. Areas where sensory nerves are concentrated or where the skin is thin hurt more.

• Relatively high-pain areas: Forehead, nose, philtrum, area around the mouth, area around the eyes, tip of the chin

• Relatively tolerable areas: Fleshy areas with lower nerve density, such as the cheeks

It is easy to feel sensitive around the mouth or eyes during the procedure, but this is a natural anatomical response rather than something unusual. Knowing this beforehand helps you feel less flustered during the moment.

📌 Key Summary: The forehead, nose, philtrum, area around the mouth, area around the eyes, and tip of the chin tend to experience stronger pain due to concentrated nerves or thin skin.

🧊 How to Reduce Pain?

There are several ways to lower pain. The key is to combine them to suit your situation.

1. Anesthetic Cream (EMLA, etc.) The most widely used method. It is usually applied for 20 to 60 minutes before the procedure, and using an occlusive dressing improves its effectiveness. However, since anesthetic cream anesthetizes the epidermal layer, it cannot completely eliminate the injection pressure and expansion pain deep inside the dermis. This answers the question: "Why does it still hurt even though I applied it?"

2. Lidocaine-Mixed Products As mentioned earlier, because an anesthetic is included in the ingredients, it reduces pain during and after the procedure.

3. Injection Method

• Drug Injectors (Injector/Mesogun): They deliver the drug more uniformly than manual injections, and the consistent depth tends to disperse the pain.

• Cannula (Blunt Needle): Used to reduce bruising and pain by minimizing the number of needle insertions, though this is not applicable to all areas or treatments.

4. Auxiliary Physical Therapy Cooling and vibration anesthesia are auxiliary means to disperse pain signals. Their role is to lessen the throbbing sensation during the procedure.

5. Sleep Anesthesia / Sedation Anesthesia If you are extremely sensitive to pain, this serves as an alternative. However, because it involves its own preparations and precautions, it is best to carefully decide whether to proceed through consultation.

Psychological factors cannot be ignored either. High anxiety makes the same stimulus feel more painful. Just relaxing and taking care of your condition before the procedure can change how you perceive the pain.

📌 Key Summary: Lower pain by combining anesthetic cream, lidocaine products, injectors, cannulas, and cooling vibration, though anesthetic cream cannot completely erase expansion pain.

🕐 How Long Does Pain Last After the Treatment?

The immediate stinging and burning sensation usually subsides within a few hours. There are some temporary side effects that may remain afterward.

• Bruising: Usually 3 to 14 days

• Swelling/Embossing (bumpy marks): A few hours to over 1 week

• Tenderness (pain when pressed): Can last for several days

Habits that help recovery are simple. Apply a cold compress after the procedure, and refrain from using irritating cosmetics, going to saunas, or doing intense exercise for a few days. These basics determine the recovery speed of swelling and bruising.

📌 Key Summary: Stinging lasts a few hours, bruising lasts 3 to 14 days, and swelling/embossing lasts a few hours to over 1 week. Cold compresses and avoiding irritation help recovery.

⚠️ Normal Reactions vs. Warning Signs

Most pain decreases over time. However, conversely, pain that progressively worsens can be a warning sign. Make sure to distinguish between the two.

The latter symptoms require suspicion of emergency complications such as vascular occlusion. Although rare, in these cases, do not endure it and immediately contact the clinic where you received the treatment to get medical attention.

📌 Key Summary: If it gradually improves, it is normal; if it worsens over time and is accompanied by paleness, discoloration, or vision abnormalities, immediate medical attention is required.

💊 Pain Management, Keep These in Mind

Pre- and post-treatment care can reduce pain and bruising.

• Pain Relievers: In terms of bruising and bleeding risks, acetaminophen (Tylenol) class drugs are the safest option. Aspirin and ibuprofen (NSAIDs) carry a risk of bruising, so consult before taking them.

• Bruising Triggers: Aspirin, NSAIDs, omega-3, ginkgo biloba extract, etc., can increase the risk of bleeding and bruising. However, do not stop prescribed medications on your own; inform the clinic of the medications and health supplements you are taking before the procedure.

• Condition Management: Drinking alcohol, excessive caffeine, and lack of sleep before the procedure increase pain sensitivity. You may also become more sensitive around your menstrual period.

📌 Key Summary: Prioritize acetaminophen for pain relievers, notify in advance about bruising-inducing ingredients/medications, and avoid alcohol and lack of sleep.

❓ Frequently Asked Questions (FAQ)

How painful are skin boosters? Does it not hurt if I apply anesthetic cream?

When using anesthetic cream, pain is commonly reported at a VAS level of 3 to 7, but individual differences are significant. Because anesthetic cream anesthetizes the epidermis, it cannot completely eliminate the injection pressure and expansion pain deep within the dermis. Even so, it is much less burdensome than undergoing the procedure without any preparation.

Which is less painful between Rejuran and Juvelook?

Generally, the polynucleotide-based line (Rejuran) tends to sting, the PLLA+HA complex (Juvelook) is moderate, and the HA-based line primarily causes a feeling of expansion. However, individual differences and variations by area are more significant than any ranking, and whether lidocaine is included greatly affects the actual sensation.

Why does it hurt even though I applied anesthetic cream?

Since anesthetic cream anesthetizes the skin surface (epidermis), the pressure pain from tissue expanding as the drug enters the dermis can still remain. This throbbing is a normal reaction and can be further mitigated with lidocaine-mixed products or injector methods.

Does greater pain mean better results?

No. Pain intensity is not proportional to treatment effectiveness. There is no evidence that harder-earned pain yields better results, so there is no need to endure it unnecessarily.

How long does pain last after the procedure?

Immediate stinging and burning subside within a few hours. Bruising can last 3 to 14 days, swelling and embossing can last from a few hours to over a week, and tenderness when pressed can also persist for several days.

Is it normal if the pain gets progressively worse after the procedure?

It may not be normal. If extreme pain worsens over time and is accompanied by pale skin, net-like discoloration, or visual anomalies, you should suspect an emergency situation like vascular occlusion and seek immediate medical care.

Is it okay to take pain relievers after the procedure?

In terms of bruising and bleeding risks, acetaminophen (Tylenol) class medicines are recommended first. Aspirin, ibuprofen, etc., carry a risk of bruising, so it is best to consult with your medical staff before taking them.

Does it hurt more during menstruation?

Pain sensitivity can increase around your menstrual period. Lack of sleep, excessive caffeine, and alcohol can also make you more sensitive to pain, so it is better to choose a day when you are in good physical condition.
