What is Rejuran effect
Rejuran is a dermal injectable containing polynucleotide DNA derived from salmon that stimulates skin healing and regeneration. It is commonly used as a skin booster to help with wrinkles, texture, and hydration. The key idea is to improve the skin’s microenvironment so it can repair itself.
The effect works by activating fibroblasts to boost collagen and elastin production. Small injections create gentle micro-injuries that trigger the skin’s natural repair process. In Korean dermatology, repeated sessions are used to achieve cumulative improvements in elasticity and moisture.
Korean clinical evidence
Korean clinical practice has accumulated a decade of data on Rejuran, with many patients reporting smoother skin and better texture. Observational studies note improvements in elasticity, hydration, and pore appearance after a series of treatments. The safety profile tends to be favorable, with transient redness or swelling resolving within a few days.
Head-to-head comparisons with other modalities show that Rejuran can be complementary to lasers and microneedling rather than a standalone fix. Outcomes depend on skin condition, age, and treatment plan, highlighting the importance of a personalized approach. For forehead wrinkles and general aging signs, clinicians often combine Rejuran with other regimens to optimize results.
Skin boosters and Rejuran
In Korea, skin boosters use PDRN to support collagen and elastin production and to reinforce the skin barrier. Rejuran Healer and related boosters can be used alone or paired with microneedling, laser, or radiofrequency to enhance penetration and effect. The core benefit is gradual improvement in skin texture, hydration, and resilience rather than instant lifting.
For patients with acne scars, dull complexions, or fine lines, boosters help soften irregularities and reduce pore visibility over time. The treatment plan is usually tailored to the target areas and combined care, including skincare and sun protection. Consistency matters because the skin’s renewal cycles drive the cumulative improvement.
Cost and safety
Cost and session count vary by clinic, region, and patient needs, with most plans built around a series of injections. In busy urban centers, packages may include multiple booster sessions spaced weeks apart to maximize collagen remodeling. Patients should expect a gradual improvement trajectory rather than overnight transformation.
Safety concerns are generally low, with common reactions limited to transient swelling, redness, or tenderness at the injection site. Rare adverse events can occur, so choosing a qualified clinician and discussing medical history is essential. For best outcomes, patients should follow aftercare guidance and maintain an ongoing skincare routine.
