If you had to name the treatment that pioneered the Korean skin booster market and continues to enjoy overwhelming popularity to this day, it would undoubtedly be 'Rejuran.' While it began as a single product, Rejuran has since developed a specialized lineup tailored to patients' diverse skin concerns and the unique characteristics of different treatment areas.

Going beyond simple full-face injections, customized treatments are now available to perfectly meet specific goals—whether that means minimizing pain or targeting fine lines around the eyes and indented scars. At Gangnam Dermatology QD Clinic,here is a clear breakdown of the features, benefits, and precautions of the four core Rejuran lineups (Healer, HB Plus, i, and S).

The Core of Rejuran: What is PN (Polynucleotide)?

To understand the Rejuran lineup, you need to know its core ingredient, PN (Polynucleotide). While it is similar to PDRN, which is commonly used in skin boosters, PN is a high-molecular-weight polymer created by linking the substances extracted from salmon DNA into longer and denser chains.

Due to its large particle size and high viscosity, it stays in the skin longer, powerfully inducing the healing of the dermal layer and collagen regeneration. The core principle of Rejuran treatments is to build a 'framework for regeneration' so that the skin can heal and become healthy on its own.

1. Rejuran Healer: The Original Regeneration Booster

Treatment Features This is the 'original' treatment that forms the foundation of the Rejuran lineup. Consisting solely of pure PN, it is densely injected into the dermal layer across the entire face to improve the fundamental environment of the skin. At QD Dermatology Clinic, Rejuran Healer is often recommended for patients who want overall skin quality improvement, including skin texture, barrier support, and fine line care.

 Key Benefits

• Overall skin regeneration and strengthening of the skin barrier across the entire face.

• Normalization of a compromised oil-water balance.

• Increased thickness of the dermal layer (resulting in a healthy, firm, and bouncy skin texture).

• Improvement of fine lines and a natural lifting effect.

 Precautions and Characteristics

• Pain and Embossing: Because pure PN is a high-molecular-weight substance, pressure is generated when it enters the dermal layer, making the procedure quite painful. Additionally, due to its slow absorption rate, an 'embossing' effect—where the injection sites swell up in small bumps resembling mosquito bites—can last for about 3 to 5 days. If you have an important event coming up, it is highly recommended to receive the treatment at least a week in advance.
