Considering Rejuran for Neck Wrinkles? Here's What to Know Before Your Procedure
Rejuran for Neck Wrinkles — From the Unique Properties of Neck Skin to the Dermis Layer Where Polynucleotides Work, How It Differs from Facial Procedures, and Pre- & Post-Procedure Care.
Horizontal neck wrinkles are always visible regardless of your expressions — so it's no surprise that many people find themselves glancing at them every time they look in the mirror. While we tend to focus on facial skincare, the neck often gets overlooked. Once those lines start catching your eye, it's natural to start looking into procedures like Rejuran.
The short answer: Rejuran-based procedures can be a viable option for neck wrinkles. That said, because the skin on the neck is thinner and subject to more movement than the face, the approach needs to be adjusted accordingly. Understanding why neck wrinkles form and which layer of skin Rejuran targets will make it much easier to determine the right plan for you.

What you'll learn from this article
· How neck wrinkles differ from facial wrinkles
· Which layer of skin Rejuran's key ingredient targets
· What changes when the procedure is performed on the neck vs. the face
· What pre- and post-procedure care is recommendedHow Are Neck Wrinkles Different from Facial Wrinkles?
The skin on the neck has a thinner Dermis* and fewer sebaceous glands than facial skin. This makes it more prone to dryness, and the repeated motion of tilting and turning your head tends to set horizontal wrinkles in earlier. Prolonged postures — like looking down at your phone or sleeping on a pillow — can cause these lines to crease even deeper over time.
Dermis*: The primary structural layer beneath the epidermis, responsible for housing Collagen and moisture to maintain skin Elasticity.
Facial wrinkles are largely driven by the interplay of expressive muscles and volume loss, whereas neck wrinkles are more heavily influenced by the inherent thinness of the skin itself, combined with loss of moisture and Elasticity. This is why approaches that focus on improving Skin Texture and replenishing hydration tend to work particularly well for the neck, rather than simply adding volume.
Which Layer of Skin Does Rejuran's Key Ingredient Target?
The active ingredient in Rejuran is polynucleotide* (PN). It is a purified DNA fragment derived from sources such as salmon, and when delivered into the Dermis, it is understood to help create an environment where the skin can retain moisture and support its own natural recovery process.
Polynucleotide*: A small chain fragment of DNA, known as PN (polynucleotide), that works within the Dermis to support moisture retention and tissue recovery.
According to a clinical evaluation on the skin regeneration effects of polynucleotide injections, approximately 87.8% of subjects showed moderate or greater improvement in the neck area, with no serious adverse events reported. That said, temporary reactions such as Swelling or Erythema are possible, so monitoring your skin's response after the procedure is advisable.
What Changes When the Procedure Is Done on the Neck vs. the Face?
The most significant difference lies in controlling injection depth and volume. Because the neck skin is thinner, the same ingredient needs to be administered more superficially and in smaller, more distributed amounts. Since the neck is also an area with significant movement, minimizing irritation during the recovery phase is especially important. Rather than completing everything in a single session, it is often more appropriate to spread the procedure across multiple visits.
| Category | Neck Procedure | Facial Procedure |
|---|---|---|
| Skin Thickness | Relatively thin | Relatively thick |
| Injection Depth | Primarily more superficial layers | Distributed by area |
| Injection Volume | Smaller, divided amounts | Relatively more flexible |
| Movement Impact | High (neck rotation) | Low |
| Recovery Care | Posture & Moisturizing attention needed | Primarily Moisturizing |
Because the neck is where horizontal wrinkles tend to crease and fold, your postural habits after the procedure can also influence the outcome. Here's a general picture of how the skin's improvement typically progresses over time.
Why Beautystone Clinic in Hongdae?
At Beautystone Clinic in Hongdae, especially when working with thinner areas like the neck, our approach prioritizes assessing your individual skin condition first — carefully determining the appropriate depth and dividing the volume accordingly, rather than injecting a large amount all at once. Because the depth of neck wrinkles and movement patterns vary from person to person, we work with each patient to determine the right timing and interval between sessions. Every procedure is performed directly by a board-certified dermatologist, and as a boutique clinic within walking distance of Hapjeong Station, we are able to give each patient the focused, unhurried attention they deserve.
Pre- and Post-Procedure Care Tips
Rejuran-based procedures generally involve minimal Downtime, but because the neck is an area of frequent movement, proper care plays an important role in helping you maintain stable, lasting results.
- Intense exercise & sauna on the day of the procedure — The combination of Heat sensation and perspiration can be irritating, so please avoid these for at least one day.
- Neck posture — Try to minimize prolonged downward head positions for a few days after the procedure.
- Moisturizing — The neck tends to dry out easily, so consistent, simple Moisturizing is key.
- Sunscreen — Apply Sunscreen to your neck just as carefully as you would to your face.
- Alcohol — Alcohol can worsen Swelling and Erythema, so it's best to reduce intake for one to two days.
Results typically develop gradually over two weeks to one or two months following the procedure, and how long they last varies from person to person. Rather than expecting a single session to resolve everything, it's advisable to monitor how your skin responds and determine the timing of follow-up visits based on that progress. This article provides general information only — please consult directly with a medical professional to determine whether this procedure is appropriate for your specific condition.
Frequently Asked Questions
Q. Can Rejuran help with neck wrinkles?
A. Polynucleotide-based procedures can certainly be considered for neck wrinkles. Clinical evaluations have reported improvements in the neck area as well. However, because the skin on the neck is thinner and moves more frequently than the face, an approach that involves shallower, more distributed injections tends to be more appropriate than a standard facial protocol. Designing the procedure around your individual wrinkle depth can help you achieve more natural-looking results.
Q. Can I see results from just one session?
A. Some patients do notice a difference after a single session, but for neck wrinkles, it is more common to spread the procedure across multiple visits spaced over time. The interval between sessions is best determined by observing how your skin responds. For personalized guidance on the number of sessions that may be right for you, we recommend consulting directly with your treating physician.
Q. Can I return to my daily routine right after the procedure?
A. Downtime is generally minimal, so most patients are able to resume normal activities fairly quickly. That said, on the day of the procedure, it's best to avoid strenuous exercise and saunas, and to minimize prolonged downward head positions for a few days. If you experience Swelling or Erythema, take it easy and monitor how your skin progresses.
Q. How long do the results last?
A. Results typically develop over two weeks to one or two months following the procedure, then gradually diminish over time. How long they last varies considerably depending on your skin condition and lifestyle habits. Consistently maintaining Moisturizing and Sunscreen application can help extend the longevity of your results.
