Question 1

What is Bioage's approach to PDRN skincare?

Accepted Answer

Bioage takes a clinical, science-first approach to PDRN skincare, using optimized concentrations of polydeoxyribonucleotide at the higher end of the topical efficacy range alongside complementary actives like EGF (epidermal growth factor), multi-peptide complexes, and potent antioxidants. Each product is developed with pharmaceutical-level precision, targeting biological aging mechanisms at the cellular level — including collagen degradation, oxidative stress, chronic inflammation, and impaired microcirculation. The brand's formulations undergo stability and potency testing that exceeds standard cosmetic industry requirements.

Question 2

Are Bioage products available in dermatology clinics?

Accepted Answer

Yes, Bioage products are recommended by skincare professionals and available through select dermatology clinics and specialized beauty retailers in South Korea. The brand's clinical positioning and rigorous formulation standards have earned it credibility among medical practitioners.

Question 3

Who is Bioage best suited for?

Accepted Answer

Bioage is ideal for consumers in their thirties and beyond who prioritize science-backed, clinical-grade skincare over trend-driven products. The brand is particularly suitable for those dealing with visible signs of aging — fine lines, loss of firmness, uneven texture, and dullness — who want products with proven active ingredients like PDRN at clinically meaningful concentrations combined with growth factors and peptides. Bioage is also a strong choice for consumers who have used professional aesthetic treatments (such as Rejuran injections or laser therapy) and want a complementary at-home maintenance regimen that supports their clinical results.

Question 4

What is the difference between Rejuran Healer, S, I, and HB?

Accepted Answer

Rejuran Healer is the original all-purpose skin booster (0.2% c-PDRN, standard viscosity) for overall skin rejuvenation, firmness, and elasticity — it is the most widely used variant and the best starting point for first-time patients. Rejuran S has a higher viscosity formulation that targets acne scars and textural irregularities by depositing concentrated PDRN directly into scar tissue for localized dermal repair. Rejuran I uses a thinner, lower-viscosity formulation specially designed for the delicate, ultra-thin periorbital skin to address dark circles, fine lines, and under-eye hollowing. Rejuran HB combines c-PDRN with non-crosslinked hyaluronic acid for dual-action hydration and regeneration, ideal for severely dehydrated or post-procedure skin. Your dermatologist will recommend the most appropriate variant based on your specific skin concerns and treatment goals.

Question 5

Is Rejuran the same as topical PDRN skincare products?

Accepted Answer

No, Rejuran products are fundamentally different from topical PDRN skincare. Rejuran products are clinical-grade injectable skin boosters administered by trained medical professionals (dermatologists and aesthetic physicians) in clinical settings using microinjection techniques. While topical PDRN products offer genuine benefits through surface and upper-epidermal penetration, Rejuran delivers c-PDRN directly into the papillary dermis where A2A receptors are most concentrated, achieving maximum bioavailability and significantly more dramatic results in skin thickness (measurable by ultrasound), elasticity (measurable by cutometer), and deep tissue repair. The two approaches are complementary: many patients use Rejuran injections for periodic intensive treatment and topical PDRN products for daily maintenance between clinical sessions.

Question 6

How often should Rejuran treatments be done?

Accepted Answer

A typical Rejuran treatment protocol involves an initial course of three to four sessions spaced two to four weeks apart, which allows each treatment to build on the collagen synthesis and tissue remodeling initiated by the previous session. Most patients begin noticing visible improvements in skin texture and elasticity after the second session. After completing the initial course, maintenance treatments are recommended every three to six months depending on individual skin condition, age, environmental exposure, and treatment goals — younger patients with mild concerns may need maintenance only every six months, while older patients or those in harsh environments may benefit from quarterly sessions. A board-certified dermatologist will assess your skin and provide a personalized treatment plan during your initial consultation.
