Rejuran Healer Dosage: What’s the Difference in Effect Between 2cc and 4cc? image 1

“Rejuran Healer comes in 2cc and 4cc dosages...

How much should I get?”

Lately, many people have been asking about Rejuran Healer because their skin has become drier.

Among the questions they ask most often is how much dosage they should receive.

A larger dosage may lead to greater effects, but 4cc is not necessarily more suitable for everyone.

It should be decided according to skin condition.

Today, I’ll explain Rejuran Healer’s basic mechanism, the real difference between 2cc and 4cc, and how to choose the dosage that’s right for you, step by step.

Rejuran Healer Dosage What is the mechanism of action within the skin?

Rejuran Healer is not simply a treatment that makes the skin look better; it is an injection procedure that helps regenerate the damaged dermal layer.

As we age, damaged cells increase within the skin.

Polynucleotides (PN), extracted from salmon DNA, which are the main ingredient in Rejuran Healer, stimulate damaged cells in the skin and help them produce collagen and elastin again.

In other words, this is not a treatment that fills volume by injecting more material, but one that induces a “regenerative response” so the skin can recover on its own.

What is the difference between Rejuran Healer 2cc and 4cc?

One syringe of Rejuran Healer contains 2cc. So in general, the procedure is performed in 2cc units.

However, the thickness of the dermal layer and the degree of damage vary from person to person, so it is best to determine the dosage accordingly.

  • 2cc → Basic care for the entire face

  • 4cc → Full-face care + strengthening for focused areas (nasolabial folds, under the eyes, cheeks)

For people in their 20s and 30s, who have fewer damaged cells, 2cc alone may be enough to manage the entire face,

but for people in their 40s and older, whose skin regeneration ability has declined, injecting 4cc may produce skin regeneration effects.

So if you mainly need skin texture and radiance care, it is recommended to receive 2cc about three times at 4-week intervals,

and if skin elasticity has declined and fine wrinkles are numerous, it is recommended to receive 4cc about three times at 4-week intervals.

Rejuran Healer What matters more than dosage?

Rejuran Healer is not a procedure where more is always better.

PN reaches cellular response saturation above a certain concentration, so excessive injection can instead cause temporary swelling or nodules.

The key is to look at the current condition of the skin and determine how much regeneration is needed, in other words, how much dosage is necessary.

It is also important how much of that dosage is injected according to skin thickness, elasticity, and the affected area.

For example, the eye area and the area around the mouth should be injected finely in shallow layers, while the cheeks and nasolabial folds should be injected more broadly in slightly deeper layers for results that look natural and last longer.

That is why an experienced practitioner designs the injection depth, density, and spacing differently for each area, even when using the same 4cc.

The dosage for Rejuran Healer should vary depending on skin condition.

By accurately diagnosing your skin condition, determining the necessary dosage, and planning which areas to focus on even within the same dosage, the effectiveness of Rejuran Healer can be improved.

Rather than relying only on good reviews, I hope you can improve the treatment effect based on what suits your own skin.
