Exosome vs Rejuran: Comparing the Differences Before Treatment
Exosome and Rejuran (PN) treatments are both skin-booster procedures aimed at improving skin condition, but they differ in their active ingredients and approach. Exosome treatments use nano-sized vesicles involved in cell-to-cell signaling, while Rejuran uses salmon-derived PN (polynucleotide) ingredients. Which treatment is suitable depends on individual skin condition and goals, so consultation with a specialist is necessary.
When researching skin-booster treatments, you'll often come across the names 'Exosome' and 'Rejuran (PN).' Both share the common goal of improving skin texture and elasticity by injecting specific ingredients into the skin, but they differ in the raw materials used and their mechanisms of action.
This article outlines the principles behind both treatments, the direction of changes you might expect, the recovery process and downtime, and what to keep in mind for aftercare. Effects and how they're experienced can vary depending on individual skin condition, and the choice of treatment should always be made in consultation with a specialist.
How Exosome Treatment Works
Exosomes are nano-sized vesicles secreted by cells, known to act as 'messengers' that carry information between cells. When used in skin treatments, this cell-to-cell signaling mechanism is described as inducing responses related to the production and reorganization of skin components.
However, the specific mechanism of action and the degree of perceived effect from exosomes can vary depending on the origin and purification method of the product used, as well as individual skin condition. Based on currently available information, it's difficult to present definitive figures or clinical results, and it's more appropriate to understand this as an area where information continues to accumulate.
How Rejuran (PN) Treatment Works
Rejuran is a treatment that injects PN (polynucleotide) ingredients extracted and purified from salmon into the skin. PN ingredients are described as being involved in the reorganization process of skin tissue, and are known as one of the skin-booster treatments that have been used clinically for a long time.
Rejuran also comes in different product lines and injection methods depending on the treatment goal (improving skin texture, elasticity, reducing fine lines, etc.), and changes are often observed through repeated treatments. Since the timing and degree of visible effects vary greatly by individual, it's important to receive thorough explanations about expected outcomes during consultation.
What's the Difference Between the Two Treatments?
The biggest difference lies in the nature of the ingredients used. Exosome treatments use vesicles involved in cell-to-cell signaling, while Rejuran uses PN, a purified biopolymer ingredient. Since the mechanisms of action differ, the expected type of change, treatment intervals, and whether to combine treatments may also differ.
It's difficult to simply compare the two treatments and determine which is superior. The suitable choice varies depending on skin type, areas of concern, and whether treatments are combined, so it's advisable to have your skin condition directly assessed and decide through consultation with a specialist.
Treatment Recovery and Downtime
Both treatments generally involve injecting ingredients using fine needles or syringes, so immediately after treatment, redness, mild swelling, flushing, or slight pain and bruising may appear at the injection site. These reactions usually subside over time, but the degree and duration can vary depending on individual skin condition and treatment area.
Returning to daily activities is known to be relatively quick, but on the day of treatment and for several days afterward, it's recommended to avoid activities that could irritate the skin, such as UV exposure, saunas, alcohol consumption, and intense exercise. Please follow the specific precautions provided by the treating clinic.
Post-Treatment Recovery and Home Care
Immediately after needle-based treatments, the skin barrier is temporarily in a sensitive state, so skincare during this period can affect the overall recovery process. The basics of home care are to focus on soothing and moisturizing with mild, low-irritation formulas.
To summarize the recovery-phase skincare routine: immediately after treatment, soothing care to calm heat and sensitivity can help, while for the following days, moisture-focused care to sufficiently hydrate the skin can be beneficial.
Summarized in FAQ Format
Post-Treatment Recovery Depends on Home Care
After needle-based treatments like Exosome or Rejuran, the skin barrier is temporarily weakened, so care that minimizes irritation while providing hydration can help with recovery. AB.Ju cream is structured in 2 steps to align with this recovery flow. Immediately after treatment, STEP1 Ultra Cera-Rich focuses on soothing and barrier care, and during the following recovery period, STEP2 Hydro Re-Boosting continues with deep moisture care. However, please note that the cream does not replace the effects of the treatment itself and should be considered only as a supplementary aid for managing skin condition.
FAQ
- Which is more effective, Exosome or Rejuran?
- Since the two treatments work through different mechanisms, it's difficult to simply compare and determine which is superior. The suitable treatment may vary depending on skin condition and areas of concern, so it's best to decide through consultation with a specialist.
- Can both treatments be done together?
- Whether combining treatments is appropriate, and the proper interval between them, can vary depending on individual skin condition and treatment goals. If considering combining treatments, please discuss thoroughly with your practitioner.
- How long is the downtime after treatment?
- Due to the nature of needle-based treatments, temporary redness, swelling, or bruising may occur, and the duration can vary by individual. For accurate guidance, please check with the clinic where you received the treatment.
- When can I start using cosmetics after the treatment?
- Since the skin is in a sensitive state immediately after treatment, it's recommended to use mild soothing and moisturizing products. For the specific timing and product recommendations, please follow the guidance provided by the treating clinic.
- How long do the effects last?
- The degree to which effects are noticeable and how long they last can vary depending on individual skin condition, number of treatments, and aftercare, so it's difficult to state this uniformly.
