Rejuran pain

Rejuran, is it only effective if it hurts? No! Something I experienced myself and found Rejuran Pain 70% Reduction SecretsRevealing how to leave behind only radiance instead of pain that brings tears, dermatologist Kim Young-kyun has honestly organized it.

Hello.Kim Young-kyun, Dermatology Specialist and Chief Director of Core Dermatology, former fellow at Hanyang University.

“Director, I heard that Rejuran is really painful... Will it make you cry your eyes out?”

“They say it's effective, but I'm too scared because of the pain.”

These are questions I hear every day in the exam room. Actually, 7 out of 10 patients who visit our Core Dermatology clinic are most concerned about the ‘Rejuran pain' before the procedure. Before recommending it to patients, I also injected Rejuran into my own face. The eye area definitely made me gasp. (laughs)

Today, we'll discuss why pain occurs with Rejuran treatments and how to scientifically manage that pain. Vast clinical data and my real-world experienceI will explain it honestly, with [something being put in].

1. Rejuran pain, why does it feel particularly painful?

PN (Polynucleotide), the main ingredient of Rejuran, has a viscosity that is different from regular HA fillers. 25-30% higher. To precisely inject this viscous component into the dermis of the skin, you need to use a very thin needle (30G-32G).

According to clinical data, approximately 68%moderate to severe pain on injectionanswers that they feel it. This is also because Rejuran's pH (7.2-7.6) temporarily stimulates our body's nerves.

“The pain is natural, caused by the ingredient's viscosity and pH. However, the pain can be reduced by more than half depending on how meticulously the practitioner performs the technique.”

2. The value proven by data is as certain as the pain.

“Director, is the pain really worth enduring?”

Yes, the reason I recommend it without hesitation is clear. It's not just a feeling of ‘good," but rather, The progress of my patients and extensive clinical data prove its effectiveness as fact.Because I am doing it.

I'll break down the key metrics you're likely curious about in an easy-to-understand way.

  • Does skin really regenerate? Receive it only 3 times at 4-week intervals. Intracellular collagen production up to 40% As it lifts, fine lines and elasticity 30-50% improvementIt can be confirmed numerically.
  • How much does it hurt? Six out of ten people (65%%) feel a slight pinch, and only about two out of ten (20%%) feel ‘it hurts a bit?’. The rest experience almost no pain.

A word from Director Kim Young-gyun “Ultimately, Rejuran is not a temporary makeup but a procedure that strengthens the skin's fundamental resilience. If you think about your skin six months from now, it's well worth the investment.”

3. Korean Skin Characteristics and Rejuran Pain

Unlike Westerners, While Koreans have a relatively thick dermis layer, they are prone to hyperpigmentation (PIH).Excessive stimulation or incorrect depth of injection can lead to prolonged redness or pigmentation after the procedure.

So for Korean patients, rather than unconditional large-volume infusions, Precise layered injection tailored to skin thicknessemphasizes this. Doing so Rejuran painNot only does it reduce, but the bruising and embossing after the procedure also disappear much faster.

4. Needles and speed are the keys to ‘Rejuran pain'.

32GB0.23Crow's feet, fine wrinkles3-43%
  • Injection depth: 1.2-1.8mm target the dermis. (If it's too shallow, it stings 25% more)
  • Injection rate: If injected faster than 0.05 mL per second, tissue pressure will increase. Pain increased by 50%I do.
  • Optimal Speed: per second 0.018–0.02 mLThe key is to infuse it very slowly.
