Dr. Jane Yoo, a board-certified dermatologist, explains Rejuran's cPDRN skincare line and how the marine-derived ingredient supports cell regeneration and collagen production. The products include a mineral sunscreen with SPF50+, a nutritive cream, and several ampoules designed to improve pores, radiance, hydration, and fine lines.
Hi everyone, I'm Dr. Jane Yoo, board-certified dermatologist and Mohs surgeon. Today I'm sharing a deep dive into Rejuran, a brand that has become recognized in skin science for its work with regenerative skincare using patented PDRN technology. Rejuran's main ingredient is cPDRN. Derived from marine sources, cPDRN was originally developed in Korea for medical use and later refined for cosmetic applications. This molecule supports natural cell regeneration and skin healing while also enhancing the activity of other ingredients such as retinol and vitamin C. It helps repair, protect, and soothe the skin barrier, even in sensitive skin types. Its ability to promote cell turnover and stimulate collagen makes it useful for smoothing, firming, addressing pigmentation, and strengthening skin resilience. So let's start with the Rejeron Healer UV Protection Cream SPF 50+ PA++++. This daily sunscreen provides broad spectrum protection through a combination of UV filters: homosalate and octisalate for UVB, oxybenzone for UVB and partial UVA, oxobenzone for UVA1, and octocrylene for UVB defense. The formula includes 0.2% CPDRN, which supports collagen and elastin production. Rejuran's Nutritive Cream 0.2% CPDRN is a replenishing moisturizer designed to repair and support stressed skin. By promoting cellular renewal and strengthening the barrier, it can help restore suppleness and resilience. Ampoules, which are highly concentrated serums intended for targeted results, are another key part of the Rejeron line. The Rejeron Turnover Ampoule 0.5% CPDRN focuses on faster renewal, improved tone, and smoother texture. The DermaHealer Pore Tightening Ampoule PDRX 5% CPDRN 0.5% uses Dot CPDRN technology to address enlarged pores, refine skin texture, and regulate sebum. The Triple Radiance Ampoule 0.5% CPDRN also uses DotCPDRN to support overall radiance and more even skin tone. It is designed to help the skin look brighter and more resilient against daily stress. The Dual Effect Ampoule 0.5% CPDRN is formulated to target both hydration and visible wrinkle improvement. DotCPDRN works alongside squalene to smooth and strengthen the skin barrier, leaving a plumped and softened appearance. Across the range, Rejeron products are centered on supporting visible renewal with cPDRN. The goal of this technology is to encourage professional-level recovery and improve resilience and radiance in a variety of skin types.
