Rejuran PDRN Products

Rejuran is the original and most recognized PDRN skin booster brand in the world, developed by Pharmaresearch Products Co., Ltd., the South Korean biotechnology company founded in 2001 that pioneered the use of polydeoxyribonucleotide in aesthetic medicine and holds the foundational patents for c-PDRN injectable formulations. Rejuran's product line represents the gold standard in PDRN-based skin rejuvenation, with a range of specialized injectable treatments that have become staples in over 5,000 dermatology clinics and aesthetic centers across South Korea, Japan, Singapore, Thailand, and an expanding list of international markets. The flagship Rejuran Healer is a skin booster injection containing highly purified salmon-derived c-PDRN at a concentration of 0.2% (2 mg/mL) that is delivered directly into the papillary dermis through microinjection techniques, stimulating collagen production, improving skin elasticity (clinical trials show a 23% improvement after four sessions), and accelerating cellular repair. Rejuran S is specifically formulated with a higher viscosity for treating acne scars and textural irregularities, offering targeted dermal repair for damaged skin through localized PDRN deposition. Rejuran I is designed for the delicate periorbital area, with a thinner, lower-viscosity formulation suitable for the ultra-fine skin around the eyes, addressing dark circles, fine lines, and thinning skin with precision. Rejuran HB combines PDRN with non-crosslinked hyaluronic acid for superior hydration alongside regeneration, making it ideal for severely dehydrated, post-laser, or environmentally stressed skin that needs both moisture replenishment and tissue repair simultaneously. What distinguishes Rejuran from topical PDRN products is its clinical-grade delivery method — intradermal injection — which ensures maximum bioavailability of the polydeoxyribonucleotide molecules by depositing them directly within the dermal matrix where A2A receptors are most densely concentrated. The brand has undergone extensive clinical trials published in peer-reviewed journals demonstrating statistically significant improvements in skin thickness (measured by ultrasound), hydration (measured by corneometer), and elasticity (measured by cutometer). As the originator of PDRN skin booster technology and the brand that launched an entire ingredient category, Rejuran has set the benchmark against which all other PDRN products — both injectable and topical — are measured, and its treatments remain among the most sought-after aesthetic procedures in Korean and Asian dermatology.
