Microneedling-apparaat - radiofrequente (RF) microneedling

Professional RF Microneedling Device

Controlled-Depth Skin Rejuvenation, Collagen Remodeling, and Tightening System

The Wikbeauty RF Microneedling Device is a professional skin-rejuvenation system combining controlled-depth microneedling with radiofrequency energy.

Adjustable microneedles penetrate the skin at depths from 0.5mm to 4.0mm while delivering controlled RF energy into the targeted tissue. This dual action supports the skin’s natural renewal response and stimulates collagen and elastin remodeling.

With four interchangeable cartridge options, adjustable RF intensity, intelligent touchscreen controls, and both facial and body applications, the system is designed for dermatology practices, medical spas, and advanced aesthetic clinics operating within local professional requirements.

Three Professional Technologies on One Platform

Controlled-Depth Microneedling

The device creates controlled microchannels at carefully selected depths. This process supports the skin’s natural repair response and encourages collagen and elastin production.

Common applications include:

• 
  Fine-line and wrinkle treatments
  
• 
  Acne-scar improvement
  
• 
  Surgical-scar treatments
  
• 
  Stretch-mark improvement
  
• 
  Enlarged-pore care
  
• 
  Skin-texture refinement
  

Radiofrequency Dermal Heating

RF energy is delivered through the microneedles into the selected tissue depth. This controlled thermal action supports deeper collagen remodeling while limiting unnecessary surface exposure.

Common applications include:

• 
  Skin-tightening treatments
  
• 
  Collagen-remodeling programs
  
• 
  Firmness and elasticity support
  
• 
  Facial and neck rejuvenation
  
• 
  Texture improvement
  
• 
  Body skin-firming treatments
  

Interchangeable Cartridge Technology

Four cartridge configurations allow professionals to adapt treatments to delicate facial zones, complete facial areas, the neck and décolleté, or larger body regions.

Common applications include:

• 
  Precision under-eye treatments
  
• 
  Full-face rejuvenation
  
• 
  Face and neck protocols
  
• 
  Décolleté treatments
  
• 
  Abdominal stretch-mark care
  
• 
  Thigh and arm rejuvenation

How a Professional Session Works

Step 1: Client Consultation

Review the client’s skin concerns, medical history, medications, previous procedures, healing response, sun exposure, and possible contraindications.

Step 2: Skin Assessment

Evaluate skin type, treatment area, concern severity, sensitivity, and suitability. Select the appropriate cartridge, needle depth, RF intensity, and treatment pattern.

Step 3: Skin Preparation

Cleanse and disinfect the treatment area according to clinical protocol. Apply a suitable topical anesthetic when professionally indicated and permitted, then remove it completely before treatment.

Step 4: Controlled RF Microneedling Treatment

Install a new sterile cartridge, confirm the selected settings, and perform the treatment using consistent passes and controlled coverage. A typical session lasts approximately 20–40 minutes.

Step 5: Post-Treatment Care

Apply professionally appropriate post-treatment products and provide written aftercare instructions covering sun protection, cleansing, hydration, skincare restrictions, and expected temporary reactions.

Frequently Asked Questions

Q: How does RF microneedling work?

The device inserts microneedles at a controlled depth while delivering RF energy into the targeted tissue. Microneedling supports the skin’s natural repair response, while RF heating promotes deeper collagen and elastin remodeling.

Q: How is RF microneedling different from standard microneedling?

Standard microneedling creates controlled microchannels. RF microneedling adds thermal energy at the selected tissue depth, providing an additional collagen-remodeling and skin-firming action.

Q: What needle depths are available?

The needle depth is adjustable from approximately 0.5mm to 4.0mm.

Q: Is the same needle depth used for every treatment?

No. Depth must be selected according to the treatment area, skin thickness, concern, client sensitivity, and professional protocol.

Q: Which cartridges are included?

The system includes 10-pin, 25-pin, 36-pin, and 49-pin cartridge options.

Q: What is the 10-pin cartridge used for?

The 10-pin cartridge supports precise treatment of small or delicate areas, including selected under-eye, nose, mouth, and small-scar applications.

Q: What is the 25-pin cartridge used for?

The 25-pin cartridge is designed for standard full-face rejuvenation, wrinkle care, skin tightening, and general texture improvement.

Q: What is the 36-pin cartridge used for?

The 36-pin cartridge provides wider coverage for the face, neck, décolleté, and other extended treatment zones.

Q: What is the 49-pin cartridge used for?

The 49-pin cartridge supports larger body areas such as the abdomen, thighs, and upper arms, including stretch-mark treatments.

Q: Which skin concerns can the machine address?

Professional applications include fine lines, wrinkles, acne scars, selected surgical scars, stretch marks, enlarged pores, reduced firmness, and uneven texture.

Q: Which areas can be treated?

Compatible areas include the face, neck, décolleté, abdomen, thighs, and upper arms.

Q: How long does a session take?

A typical professional session lasts approximately 20–40 minutes, excluding consultation, cleansing, and topical-anesthetic time.

Q: Is topical anesthetic required?

A topical anesthetic may be used when professionally appropriate and legally permitted. The operator must follow the product instructions and local requirements.

Q: Is the treatment painful?

Client experience varies. With suitable preparation and correctly selected settings, most clients describe temporary pressure, warmth, or prickling rather than severe pain.

Q: How many sessions are recommended?

A typical starting course includes approximately 3–6 sessions.

Q: How far apart should treatments be scheduled?

Sessions are commonly spaced approximately 4–6 weeks apart to allow the skin to recover and remodel.

Q: Is there downtime?

Temporary redness, sensitivity, or mild swelling may last approximately 1–2 days. Recovery varies according to the treatment depth, RF intensity, area, and individual response.

Q: When can clients expect visible changes?

Some clients notice early texture improvements after initial sessions. Collagen remodeling develops gradually, with more visible changes commonly appearing over several weeks.

Q: How long can results last?

The supplied estimate is approximately 12–18 months with suitable skincare and maintenance. Individual result duration varies.

Q: Is RF microneedling suitable for every skin tone?

Adjustable settings may allow trained professionals to treat a broad range of skin tones. However, suitability and settings must be determined through an individual assessment.

Q: Can active acne be treated?

Treatment should not be performed over active infection, open lesions, or significant inflammation. The client should be assessed by an appropriately qualified professional.

Q: Can the device be used on scars?

It can support treatments for fully healed acne scars and selected surgical scars. Active wounds and incompletely healed tissue must not be treated.

Q: Are cartridges reusable?

Needle cartridges should be sterile and single-use. A new cartridge must be used for every client and every treatment session.

Q: What aftercare is recommended?

Clients should follow the professional aftercare plan, use broad-spectrum SPF 30 or higher, avoid harsh skincare for approximately 3–5 days, and avoid swimming, saunas, and excessive heat for at least 48 hours.

Q: Who can operate the device?

The operator must have the qualifications, training, licensing, supervision, and insurance required in the location where treatments are provided.

Q: Does training come with the machine?

Yes. Professional machine-operation and treatment guidance are included. This training does not replace legally required clinical qualifications or licenses.

Q: What certificates are included?

The device is supplied with CE and ISO certificates.
