Rejuran vs Juvelook: Differences and How to Choose
Rejuran is a skin booster based on PN (polynucleotide), focusing on skin condition and texture care, while Juvelook is based on PDLLA (poly-D,L-lactic acid) and is more focused on volume and elasticity care. Both may cause swelling, redness, or dryness for a few days after treatment, so aftercare is important, and the safest way to choose between them is to consult a specialist based on your skin condition and desired outcome.
When researching skin booster treatments, one of the first questions that comes up is 'Rejuran or Juvelook?' Both treatments work by injecting ingredients into the skin to help improve skin condition, but the ingredients used and the direction of expected results differ slightly.
This article covers the differences in ingredients and mechanisms between the two treatments, the recovery timeline afterward, and how to approach home care during that period.
What's the Difference Between Rejuran and Juvelook
Rejuran is based on PN, or polynucleotide. PN is a DNA-derived ingredient extracted from sources such as salmon, and is known to help with skin condition and texture care. It's often chosen for concerns like dull tone or rough texture, with a focus on overall skin condition care.
Juvelook uses PDLLA, or poly-D,L-lactic acid. PDLLA is a polymer substance that gradually breaks down in the body, and this treatment is often introduced with more of a focus on volume and elasticity care. However, actual results can vary depending on individual skin condition and treatment area.
Treatments like Rivive and Retigen also fall under the broader category of skin boosters, with detailed differences depending on their ingredients and purposes. Regardless of which treatment you're considering, it's important to have a thorough consultation with a specialist beforehand to check which option suits your skin condition.
What Changes to Expect in the Days After Treatment
For about 1–2 days right after treatment, injection marks, mild swelling, and redness may appear. Since the skin is sensitive during this period, it's best to avoid irritating cosmetics and focus on soothing care.
From day 3–4, swelling tends to subside and redness gradually fades. However, the skin may still feel dry during this period, so it's important not to neglect moisturizing care.
From about a week after treatment, most people can return to their regular skincare routine, though the time it takes for skin to fully settle can vary by individual. Recovery speed may differ depending on the treatment area, intensity, and individual skin condition.
Home Care by Stage: How to Manage Your Skin
For about the first 3 days after treatment, it's best to minimize irritation while cleansing and use gentle, soothing products to care for the skin. During this period, it's safer to avoid hot water cleansing, exfoliation, and strong massage.
From day 4 onward, as the skin enters the recovery period and gradually stabilizes, it's common to feel tightness or dryness. Switching to care that thoroughly replenishes moisture and hydration during this time can help manage skin condition.
Approaching post-treatment care in stages allows for a much more systematic way to look after the skin. Distinguishing between the initial soothing stage and the later moisture-boosting stage is an important part of maintaining stable results.
Home Care Makes the Difference in Post-Treatment Recovery
During the recovery period after skin booster treatments (from day 4 onward), the skin barrier is still sensitive, making deep hydration care especially important. AB'EAU Hydro Re-Boosting Cream is formulated with ingredients like niacinamide, panthenol, and beta-glucan to help support deep hydration and texture care during the recovery period, making it suitable for use as STEP2 (from day 4 onward) home care after skin booster treatments like Rejuran or Juvelook.
FAQ
- What is the biggest difference between Rejuran and Juvelook?
- Rejuran is known as a treatment based on PN (polynucleotide) that focuses on skin condition and texture care, while Juvelook is based on PDLLA (poly-D,L-lactic acid) and is generally geared more toward volume and elasticity care. However, actual results can vary depending on individual skin condition, so it's best to decide through a consultation.
- What exactly are PN and PDLLA?
- PN (polynucleotide) is a DNA-derived ingredient extracted from sources such as salmon, while PDLLA (poly-D,L-lactic acid) is a polymer substance that gradually breaks down in the body. Since these ingredients differ in characteristics and mechanism of action, the choice between them may depend on the purpose of treatment.
- How many days do swelling or redness typically last after treatment?
- This varies by individual, but swelling and redness typically appear within the first 1–2 days after treatment and tend to gradually subside from around day 3–4. Recovery speed may differ depending on the treatment area and intensity.
- What criteria should I use to choose a treatment?
- If skin tone or texture care is the priority, Rejuran-type treatments are often recommended, whereas if volume or elasticity care is the priority, Juvelook-type treatments are often suggested. However, this is only a general tendency, and the safest approach is to have your skin condition diagnosed and decide through a consultation with a specialist.
- When and how should I start home care after treatment?
- For the first 1–3 days after treatment, it may help to focus on gentle, soothing care, then shift to hydration-focused care from the recovery period starting around day 4. Approaching aftercare in stages like this can help maintain stable skin condition.
