| Item | Description |
|---|---|
| Composition & Mechanism | PN (polynucleotide) is injected into the dermis to support the skin’s recovery response and moisture-retention environment. |
| WayB approach | Rejuran is combined with Comfort Solution and injected in divided doses with a small, thin needle, tailored to the skin thickness of each area. |
| Suitable for | Cases requiring recovery care for underlying dryness, fine lines, thinned skin, or skin sensitized after laser treatments |
| Procedure time | About 20–30 minutes (topical anesthesia time separate) |
| Pain level | Topical anesthesia, Comfort Solution, and fine-needle injection reduce discomfort, but there is individual variation. |
| Onset of effect | Changes in skin texture and dryness are generally observed over 2–4 weeks. |
| Recommended sessions & interval | Typically 3–4 sessions at 2–4 week intervals as a baseline, with response reassessed after 2 sessions. |
| Downtime | Temporary raised bumps (small papules) generally subside within 1–3 days. Redness, swelling, and bruising may accompany the procedure, and duration varies by individual. |
Rejuran is a medical device whose main ingredient is PN (polynucleotide), formulated with Pharma Research’s DOT technology. At WayB, we assess concerns about skin condition — texture, fine lines, elasticity, and more — to determine whether Rejuran treatment is suitable.
Even when skin concerns are similar, skin thickness, dryness, sensitivity, and prior treatment experience can differ. Before the procedure, we check your skin condition and the changes you want, and explain the products used, the injection method, and the recovery process together with you.
Comfort Rejuran is an in-clinic treatment program that adds WayB’s proprietary Comfort Solution to Rejuran and adjusts the fine needle and injection method to reduce the burden of pain.
Based on the characteristics of the Rejuran product, we check each individual’s pain sensitivity and skin condition before proceeding. Pain levels vary by individual, and swelling, temporary raised bumps, redness, and bruising may appear after the procedure. Along with a comfortable treatment process, we also explain the expected recovery response and aftercare.
Unlike fillers, which create volume immediately within the skin, PN works by supporting the dermis’s recovery environment. Because small amounts are injected at multiple points, temporary papules may form on the skin’s surface, which are absorbed over time.
| Component | WayB’s Approach |
|---|---|
| Injected ingredient | Rejuran (PN) combined with WayB’s Comfort Solution. |
| Injection method | Manual fine-needle injection using a small, thin needle, or X-Injector, chosen according to skin condition and treatment area. |
| Injection design | Depth, volume, and speed are adjusted based on the skin thickness and sensitivity of each area. |
| Pain management | Topical anesthesia, Comfort Solution, and adjustment of the injection method are applied together. |
Before starting, a stop signal is agreed upon, and if pain increases during the procedure, the speed and the amount injected at one time are adjusted.
Small papules are a normal injection response and generally subside within 1–3 days. In areas with thinner skin, such as around the eyes, they may be visible a bit longer, and bruising and swelling vary by individual.
The core main ingredient is the same Rejuran PN. At WayB, we combine it with Comfort Solution to reduce the burden of the injection process, and inject it carefully in divided doses with a small, thin needle.
No. Topical anesthesia, Comfort Solution, and fine-needle injection reduce the burden of pain, but discomfort can vary depending on skin thickness, sensitivity, and the treatment area.
No, it is different. A Hydrating Skin Booster (Water-Glow Injection) mainly involves injecting hyaluronic-acid-based moisturizing ingredients, while Rejuran is a regenerative skin booster based on PN. The purpose and recommended plan differ.
Some people notice a change after a single session, but since this treatment aims for skin recovery, 3–4 sessions at 2–4 week intervals are generally used as a reference. At WayB, we check the response after 2 sessions and adjust the plan.
Small papules generally subside within 1–3 days. They may be visible longer depending on thin areas such as around the eyes, skin condition, and the amount injected.
Depending on skin condition and treatment area, manual fine-needle injection or X-Injector may be considered. Since no single method is more suitable for every area, the decision is made after consultation.
