Kiara Reju product description
Kiara Reju combines PDRN 5 mg/mL, hyaluronic acid 20 mg/mL, and niacinamide 1 mg/mL in a single aesthetic skin-booster formulation.
PDRN provides the regenerative component of the treatment, while hyaluronic acid supports hydration and moisture retention. In addition, niacinamide complements the formulation by supporting the skin barrier and a more even-looking complexion. Together, these ingredients create a multi-action approach to skin rejuvenation designed to improve the overall appearance and quality of the skin, resulting in a radiant glow and youthful appearance.
BioPlus Co., Ltd. develops Kiara Reju with its advanced technology. Based in South Korea, this biopharmaceutical company specializes in creating medical devices and aesthetic products out of natural raw materials with unique technology and advanced facilities. Designed as an all-in-one anti-aging solution, Kiara Reju induces the production of collagen and elastin to rejuvenate the skin and retain the moisture of the skin.
Kiara Reju Skin Booster also improves the appearance of moderate to severe facial wrinkles and folds. Practitioners primarily inject it into the superficial dermis or subcutaneous tissue to repair the damaged skin barrier through stimulation of growth factors and tissue regeneration.
Key benefits of the Kiara Reju ingredients
Six aspects of skin quality the formulation aims to support.
Hydration
Hyaluronic acid helps attract and retain moisture, supporting a smoother and more supple appearance. It also maintains sebum production, locking in the facial moisture balance through the Natural Moisture Factor (NMF).
Skin renewal
PDRN provides regenerative support as part of a professional skin-rejuvenation approach. It also helps increase dermal density and thickness, providing a more youthful appearance.
Elasticity
The combination of PDRN and hydration support aims to promote firmer and more resilient-looking skin.
Improved texture
Improved hydration and skin quality can help create a smoother-looking skin surface.
Radiance and skin tone improvement
Niacinamide complements the formulation to support a brighter and more even-looking complexion.
Fine-line appearance
Improved hydration and overall skin quality may help soften the appearance of fine and superficial lines.

How to use Kiara Reju
Kiara Reju is an injectable professional-use skin booster. For this reason, only a qualified healthcare professional with appropriate training in aesthetic injectable procedures should administer it.
The treating professional should determine the appropriate treatment technique, injection depth, amount, treatment area, and frequency based on the patient’s anatomy, skin condition, medical history, and treatment goals.
Professional treatment process
- Consultation and assessment The practitioner evaluates the patient’s skin condition, medical history, concerns, previous aesthetic procedures, and desired outcomes.
- Treatment planning The practitioner then determines the appropriate treatment areas and develops an individualized treatment plan.
- Skin preparation Before treatment, the practitioner cleanses and prepares the treatment area using appropriate clinical hygiene and infection-control procedures.
- Professional administration The practitioner then administers Kiara Reju using an appropriate professional injection technique and sterile equipment in accordance with the manufacturer’s instructions and applicable regulations.
- Post-treatment care Afterwards, the practitioner provides individualized aftercare instructions and explains which activities or skincare products the patient may need to avoid temporarily.
- Follow-up Finally, the practitioner may perform a follow-up evaluation to assess the patient’s response and determine whether additional or maintenance treatments are appropriate.
Suggested treatment protocol
A commonly described Kiara Reju protocol consists of:
Initial course
3 treatment sessions
Treatment interval
Approximately 1 month between sessions
Maintenance
Individualized to the patient’s skin condition and treatment goals
However, treatment schedules are not universal. Instead, the treating professional should determine the appropriate protocol for each patient.
Aftercare
After Kiara Reju treatment, patients should follow the individualized instructions provided by their treating professional.
Depending on the treatment technique and patient’s condition, the practitioner may recommend temporarily avoiding:
- Touching or massaging the treated area
- Intense exercise
- Excessive heat
- Saunas and steam rooms
- Direct sun exposure
- Certain active skincare products
- Alcohol consumption immediately after treatment
In any case, the treating professional should provide the final aftercare recommendations based on the patient’s treatment.
Results and duration of effect
Some product information reports visible improvements beginning approximately one week after treatment. However, results vary depending on the individual’s skin condition, treatment technique, treatment schedule, and response.
Available product information reports results lasting approximately 6–12 months. Practitioners may consider maintenance treatments according to individual needs and professional assessment.
Because individual responses vary, results have no guaranteed duration.
