Rejuran Guide: Ingredients, Effects, Differences Between Black/White/Blue/Red Boxes & Side Effects — Safely Achieve K-Star Glass Skin!

How do K-stars maintain their signature “glass skin”? The secret often lies in beauty injectables! Rejuran has surged in popularity across Korea and Hong Kong in recent years, with widespread buzz on social media. Dubbed the secret weapon behind radiant, youthful skin, Rejuran is a treatment that helps restore glow and elasticity.

1. What is Rejuran?

Rejuran is a medical aesthetics brand under PharmaResearch Products (PRP) Korea, a company recognized for its expertise in regenerative medicine. The name Rejuran combines Rejuvenation (revival of youth) and Regeneration (skin repair), reflecting its core brand value.

The Core Ingredients: PDRN & PN

The secret behind Rejuran lies in its star ingredients: PDRN (Polydeoxyribonucleotide) and PN (Polynucleotide).

Both are bioactive substances extracted from salmon DNA. Salmon is chosen because its DNA is highly compatible with human cells, reducing the risk of skin inflammation and ensuring excellent biocompatibility. These nucleotides trigger the skin’s self-repair mechanisms, improving a wide range of concerns and slowing down aging.

• PDRN molecules are smaller, targeting superficial skin issues and improving overall skin texture.
• PN molecules are larger, providing structural support to boost elasticity and firmness.

Rejuran’s PDRN/PN is extracted from wild salmon in Korea’s Namdaecheon River using patented DOT™ technology, which preserves maximum bioactivity for stronger results.

2. Injection Frequency & Duration of Results

• Initial course: 3 sessions spaced 3–4 weeks apart.
• Maintenance: Periodic touch-ups help sustain results.
• Longevity: Results typically last 3–6 months, depending on skin condition and lifestyle.

Unlike traditional skin boosters that focus only on hydration, Rejuran prioritizes deep repair and regeneration. By delivering PDRN/PN into the dermis, it stimulates collagen and elastin production, restoring elasticity and refining texture.

Benefits of Rejuran Treatments:

• Repairs the skin barrier & balances oil-water levels (great for sensitive skin).
• Stimulates collagen & elastin for firm, bouncy skin.
• Reduces fine lines, wrinkles & pore size for youthful glow.

Treatment Combinations (1+1 > 2 Formula)

Pairing Rejuran with other procedures can amplify results:

• Hydration infusion: For dehydrated skin.
• Microneedling: Enhances absorption & collagen stimulation.
• Picosecond laser: Targets pigmentation, brightens skin.
• HIFU (Ultrasound Lift): Lifts and tightens early signs of sagging.
• RF Microneedling: Comprehensive tightening and skin texture improvement.
