Renuva Fractional Laser Treatment: A Comprehensive Step-by-Step Guide for Practitioners

Renuva is a next-generation non-ablative fractional laser system designed for advanced skin resurfacing with no downtime and exceptional patient comfort. By creating precise Micro-Thermal Zones (MTZs), Renuva activates the skin’s natural repair response and stimulates deep collagen regeneration.

The result? Noticeable improvements in:

• Skin texture and tone

• Enlarged pores

• Acne scars and surgical scars

• Fine lines

• Overall skin quality and radiance

  
  

Powered by patented Optische-Tracking Technology, Renuva delivers consistent, controlled energy with every pulse. This ensures smoother treatments, enhanced safety, and predictable clinical outcomes, making it an ideal device for daily clinical practice.

Its versatility allows practitioners to perform both full-face rejuvenation and targeted correction treatments with precision and efficiency.

Below is a detailed overview of the treatment process.

1. Client Consultation & Assessment

A comprehensive consultation is the foundation of a safe and effective treatment. During this stage, the practitioner reviews the patient’s medical history, including any history of photosensitivity, recent isotretinoin use, active skin infections, pregnancy, or a tendency toward keloid formation. The patient’s skin type is assessed using the Fitzpatrick scale, and specific concerns such as acne scars, enlarged pores, or fine lines are carefully evaluated.

Clear communication is essential at this stage. The practitioner explains realistic expectations, the number of sessions likely required, potential side effects, and the minimal downtime associated with non-ablative fractional treatments. Standardized before-treatment photographs are taken for documentation and progress tracking, and informed consent is obtained prior to proceeding.

2. Pre-Treatment Preparation

Proper skin preparation ensures both safety and optimal results. The treatment area is thoroughly cleansed and disinfected to remove impurities, oil, and makeup. Depending on the patient’s sensitivity and treatment intensity, a topical anesthetic may be applied and allowed sufficient time to take effect. Before beginning the laser procedure, the anesthetic is completely removed from the skin.

Protective eye shields are placed on both the patient and the practitioner to ensure ocular safety. The practitioner then selects the appropriate laser parameters, carefully adjusting energy levels, density, and pulse duration according to the patient’s skin type and treatment goals. Correct parameter selection is critical to achieving effective collagen stimulation while maintaining patient comfort and safety.

3. Fractional Laser Application

Once preparation is complete, the fractional laser treatment begins. A test pulse may be performed when indicated to confirm appropriate skin response. The laser is applied in controlled, uniform passes across the treatment area, creating precise microthermal zones within the skin.

Throughout the procedure, the practitioner maintains consistent overlap without excessive stacking to ensure even coverage and avoid overtreatment. The skin’s response is continuously monitored for appropriate clinical endpoints such as mild erythema and subtle edema. If necessary, settings may be adjusted during the procedure to optimize efficacy while maintaining safety.

Thanks to Optische-Tracking Technology, energy delivery remains stable and consistent across the treatment area. Most patients report a mild warming sensation or light prickling discomfort, which is generally well tolerated.

4. Immediate Post-Treatment Care

Immediately after treatment, the skin may appear slightly red and feel warm, similar to a mild sunburn. Mild swelling can also occur, depending on the treatment intensity and individual skin sensitivity. Cooling measures such as cold air or cooling packs may be used to enhance patient comfort.

A soothing, barrier-repair, or post-laser recovery product is applied to calm the skin and support the healing process. Because Renuva is non-ablative, the skin surface remains intact, allowing patients to resume normal daily activities immediately after treatment.

5. Post-Treatment Instructions

Clear aftercare guidance is essential to protect the skin and optimize results. Patients are advised to avoid:

direct sun exposure and apply a broad-spectrum SPF 30–50 sunscreen daily. Heat exposure, including saunas, hot showers, and intense exercise, should be avoided for 24 to 48 hours following treatment.

• Direct sun exposure and apply a broad-spectrum SPF 30–50 sunscreen daily.

• Heat exposure, including saunas, hot showers, and intense exercise, should be avoided for 24 to 48 hours following treatment.

• Patients should refrain from picking, scrubbing, or exfoliating the treated area.

• To support your skin’s healing and nourishment after laser treatment, follow this routine: use a nutrition ampoule every day, use a hydrating mask at least 3 times for the first week, later once a week after first week, continue to support moisture balance and skin health as your skin recovers.

• Mild redness or light flaking may occur for several days, depending on treatment intensity. Emphasizing proper sun protection is particularly important to reduce the risk of post-inflammatory hyperpigmentation.

6. Follow-Up & Treatment Plan

Fractional laser treatments stimulate collagen remodeling, which continues progressively over several weeks. A follow-up visit is typically scheduled within two to four weeks to assess skin response and plan subsequent sessions.

Depending on the indication, multiple treatments may be recommended to achieve optimal outcomes. With each session, cumulative collagen stimulation leads to gradual and natural-looking skin improvement.

7. Documentation

Thorough documentation is an essential component of professional practice. The practitioner records the laser type, treatment parameters, number of passes, and treatment areas, along with the patient’s immediate skin response and tolerance level. Aftercare instructions and any relevant observations are also documented.

Accurate records support treatment consistency, patient safety, and long-term clinical success.

Renuva also works synergistically with fillers, botulinum toxin, and cosmetic surgery by addressing concerns such as texture irregularities and scarring — issues that injectables or surgery alone cannot fully correct.

For dermatologists, aesthetic physicians, and plastic surgeons, Renuva offers a true “lunchtime treatment” with visible results and zero disruption to patients’ daily routines.
