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

Is COSRX cruelty-free?

Accepted Answer

COSRX is a cruelty-free brand that does not test its products on animals. The brand is certified by Leaping Bunny and PETA, and it does not sell in markets where animal testing is required by law. Many COSRX products are also vegan-friendly, though consumers should check individual product labels for specific formulations.

Question 5

Where can I buy COSRX PDRN products?

Accepted Answer

COSRX PDRN products are widely available through major retailers including Amazon, Sephora, Ulta Beauty, YesStyle, and the official COSRX website (cosrx.com). In South Korea, they can be found at Olive Young stores nationwide. The brand ships internationally from most of these retailers, making their PDRN line accessible to consumers globally.
