Rejuran — Korean Polynucleotide (PN) Skin Booster

No, under the strict halal opinion most GCC patients follow. Rejuran is purified salmon DNA — fish-DNA halal status is contested between schools (lenient opinion accepts fish by default; strict opinion requires fish-processing verification). The standard salmon-DNA injectable supply chain does not document halal-compliant fish processing. We classify Rejuran as not halal under the strict interpretation. Halal substitution: Reset Regenerative biostimulator for cellular regeneration, or Profhilo for skin-barrier restoration.

Rejuran S — standard skin booster, acne scars, general skin renewal. Rejuran HB — adds hyaluronic acid for hydration emphasis; popular for dehydrated mature skin. Rejuran I — formulated for the delicate under-eye area, smaller injection volume per point. Your physician will map your skin concern to the right variant; many patients use S + I in combination on the same visit.

Korean aesthetic culture has familiar trust with Rejuran — PharmaResearch is a Korean company, and Rejuran has been a Korean clinic standard since 2014. Most Korean visitors specifically request Rejuran by name. We honour that brand-trust by using identical Korean-source product, supplier-verified, with the same clinical protocols Seoul clinics use. Patients who experienced Rejuran in Seoul receive the equivalent product here.

Rejuran Healer is the ORIGINAL product (launched 2014, PharmaResearch Korea) — the foundational polynucleotide formulation. Rejuran S is the SECOND-generation upgrade (launched 2018) with higher PN concentration and improved viscosity, specifically optimised for ACNE SCARS and atrophic depressions. They share the same active mechanism (salmon-DNA polynucleotides) but Rejuran S delivers a stronger remodelling signal at scarred sites. At Waleerat, we recommend Rejuran S for visible acne scarring + dermal-thickness loss, Rejuran Healer for general skin-quality maintenance, and Rejuran I for the under-eye specifically. Pricing identical at ฿6,500/ampoule across all three variants.

A Rejuran injection is a meso-style injection of polynucleotide (PN) — small-volume dermal injections placed across the treatment area (face, neck, under-eye) using a 30G or finer needle (or microneedle stamp for facial coverage). One full-face session takes 30-45 minutes including topical numbing. The polynucleotides settle into the dermis where they stimulate fibroblast activity and tissue repair over the following 4-6 weeks. The full Rejuran program is typically 3 sessions spaced 2-4 weeks apart; effects build progressively over 12 weeks and last 6-12 months.
