Question 1

Is CNP Laboratory really founded by a dermatologist?

Accepted Answer

Yes, CNP Laboratory was founded in 1996 by Dr. Chung-ho Lee, a board-certified dermatologist who operates the Cha & Park Dermatology Clinic in Seoul. With nearly 30 years of clinical practice informing its product development, the brand's formulations are developed based on direct dermatological research and real patient outcomes. CNP products are frequently recommended by skincare professionals across Korean dermatology clinics and medical spas as both standalone treatments and post-procedure recovery aids.

Question 2

What makes CNP Laboratory's PDRN products unique?

Accepted Answer

CNP Laboratory combines PDRN with its proprietary ingredient technologies developed through years of dermatological research. Each product undergoes rigorous clinical testing that goes beyond typical cosmetic standards, ensuring measurable efficacy and safety backed by genuine medical expertise.

Question 3

Can CNP Laboratory products be used after dermatological procedures?

Accepted Answer

CNP Laboratory products are frequently recommended by Korean dermatologists as part of post-procedure skincare regimens following laser treatments, chemical peels, microneedling, and injectable procedures like Rejuran skin boosters. Their gentle yet effective formulations, including PDRN products, are designed to support skin recovery and regeneration without causing irritation to sensitized post-procedure skin. The PDRN component is particularly beneficial post-procedure because it promotes tissue repair and suppresses inflammation through the same A2A receptor pathway activated by clinical PDRN injections. However, always consult your dermatologist for specific post-procedure skincare advice and timing.

Question 4

What is the difference between Rejuran Healer, S, I, and HB?

Accepted Answer

Rejuran Healer is the original all-purpose skin booster (0.2% c-PDRN, standard viscosity) for overall skin rejuvenation, firmness, and elasticity — it is the most widely used variant and the best starting point for first-time patients. Rejuran S has a higher viscosity formulation that targets acne scars and textural irregularities by depositing concentrated PDRN directly into scar tissue for localized dermal repair. Rejuran I uses a thinner, lower-viscosity formulation specially designed for the delicate, ultra-thin periorbital skin to address dark circles, fine lines, and under-eye hollowing. Rejuran HB combines c-PDRN with non-crosslinked hyaluronic acid for dual-action hydration and regeneration, ideal for severely dehydrated or post-procedure skin. Your dermatologist will recommend the most appropriate variant based on your specific skin concerns and treatment goals.

Question 5

Is Rejuran the same as topical PDRN skincare products?

Accepted Answer

No, Rejuran products are fundamentally different from topical PDRN skincare. Rejuran products are clinical-grade injectable skin boosters administered by trained medical professionals (dermatologists and aesthetic physicians) in clinical settings using microinjection techniques. While topical PDRN products offer genuine benefits through surface and upper-epidermal penetration, Rejuran delivers c-PDRN directly into the papillary dermis where A2A receptors are most concentrated, achieving maximum bioavailability and significantly more dramatic results in skin thickness (measurable by ultrasound), elasticity (measurable by cutometer), and deep tissue repair. The two approaches are complementary: many patients use Rejuran injections for periodic intensive treatment and topical PDRN products for daily maintenance between clinical sessions.

Question 6

How often should Rejuran treatments be done?

Accepted Answer

A typical Rejuran treatment protocol involves an initial course of three to four sessions spaced two to four weeks apart, which allows each treatment to build on the collagen synthesis and tissue remodeling initiated by the previous session. Most patients begin noticing visible improvements in skin texture and elasticity after the second session. After completing the initial course, maintenance treatments are recommended every three to six months depending on individual skin condition, age, environmental exposure, and treatment goals — younger patients with mild concerns may need maintenance only every six months, while older patients or those in harsh environments may benefit from quarterly sessions. A board-certified dermatologist will assess your skin and provide a personalized treatment plan during your initial consultation.
