This Clinical Safety & Usage Handbook is designed to help you use your Skinneedlepro device safely, responsibly, and effectively in a home setting.

Skinneedlepro devices use microneedling technology (also known as Collagen Induction Therapy) to create controlled micro-channels in the skin’s surface. When used correctly, this process may support smoother-looking skin and improved absorption of topical skincare products. However, microneedling involves skin penetration and must be performed with care.

This handbook provides clear, step-by-step guidance on:

1. Safe device handling and preparation;
2. Correct cartridge selection and single-use requirements;
3. Appropriate needle depths for different facial areas;
4. Hygiene, sterilisation, and infection-prevention practices; and
5. Aftercare and skin recovery guidelines.
   

The information in this handbook is intended for general guidance only and is written for consumer home use, not professional or clinical treatment. It does not replace medical advice. Results and tolerance vary between individuals.

Improper use of microneedling devices may cause adverse effects including irritation, infection, scarring, or changes in pigmentation. Following the instructions in this handbook is essential to minimise risk.

If you have a pre-existing skin condition, active acne, a history of abnormal scarring, are pregnant, or are unsure whether microneedling is suitable for you, consult a qualified healthcare professional before use.

By using a Skinneedlepro device, you acknowledge that you have read and understood this handbook and agree to follow the safety instructions contained within it.

This handbook is provided strictly for educational and informational purposes.

This device is a cosmetic tool and not a medical device. Microneedling involves controlled skin injury and carries inherent risks including infection, scarring, pigmentation changes, irritation, and allergic reactions.

By accessing and using this information, you acknowledge that you assume all risks associated with microneedling and agree to consult a qualified medical professional if unsure of suitability.

If you do not agree, do not proceed.

Do not use this device if you have active acne, open wounds, infections, herpes simplex, fungal or bacterial skin conditions, a history of keloid scarring, bleeding disorders, uncontrolled diabetes, autoimmune conditions, or if you are pregnant or breastfeeding.

If you are under medical treatment or unsure of suitability, consult your healthcare provider before use.

To operate the “Electric Microcrystal Introducer” safely, the user must understand the biological cascade it initiates. The device does not merely puncture the skin; it modulates the body's wound-healing mechanism to restructure the extracellular matrix.

3.1 The Histology of Micro-Trauma

The skin is a complex organ comprised of the epidermis (barrier) and the dermis (structural support). The microneedling pen uses a vertical reciprocating motor to drive needles through the stratum corneum and into the viable tissue. This creates a “micro-channel,” a controlled physical wound that triggers three distinct physiological phases:

• Hemostasis and Inflammation (Hours 0-72):

Upon penetration of the papillary dermis, rupture of capillaries leads to pinpoint bleeding. Platelets aggregate at the injury site, releasing chemotactic factors such as Platelet-Derived Growth Factor (PDGF) and Transforming Growth Factor Beta (TGF-β). Neutrophils invade the wound to clear debris and bacteria. Clinically, this manifests as erythema (redness), edema (swelling), and warmth. This inflammation is not a side effect; it is the catalyst for repair.

• Proliferation (Days 3-21):

Fibroblasts migrate to the micro-channels, stimulated by the growth factors released during inflammation. They begin to synthesize a provisional extracellular matrix composed of Type III (embryonic) collagen, elastin, and glycosaminoglycans (hyaluronic acid). Simultaneously, angiogenesis (formation of new blood vessels) occurs to supply oxygen to the rebuilding tissue. This is the “induction” phase where the skin physically thickens.

• Maturation and Remodeling (Months 1-24):

Over several months, the Type III collagen is slowly replaced by stronger, more organized Type I collagen. The collagen fibers align along the stress lines of the skin, resulting in tightening and smoothing of wrinkles and scars. This phase can continue for up to two years post-treatment.

3.2 Transdermal Drug Delivery (Nano-Infusion)

Distinct from collagen induction, the Nano-cartridge functions via a different mechanism. It utilizes a silicone or steel chip with microscopic pyramids (approx. 0.15mm height) that do not penetrate the dermis. Instead, they separate the keratinocytes of the stratum corneum, creating transient aqueous channels. This bypasses the skin's lipid barrier, allowing large molecules (like Hyaluronic Acid) to penetrate the epidermis by up to 3000% more effectively than topical application alone, without triggering a full wound-healing response.

The SkinNeedlePro microneedling system is an automated cosmetic device designed to support skin texture refinement and enhanced topical product absorption.

It is intended for personal, non-commercial cosmetic use only and must be operated strictly in accordance with safety guidance.

Based on the provided manual images and technical research, the “Electric Microcrystal Introducer” is a precision-engineered instrument. Proper handling of its components is essential for consistent motor performance and needle depth accuracy.

4.1 Technical Schematics

The device consists of the following key components:

Reciprocating Motor: The core engine that converts electrical energy into vertical mechanical motion. The stability of the motor determines the cleanliness of the puncture; a weak motor may cause the needles to drag or snag.

Integrated Chip: A microprocessor that regulates the RPM (Revolutions Per Minute) of the motor, ensuring consistent speed even as resistance (skin thickness) changes.

Adjustor Ring (Graduated Display): A rotary dial located on the neck of the pen. This mechanism physically extends or retracts the cartridge seating, controlling needle depth from 0.25mm to 2.5mm.

Power System:

• Input Voltage: 5V 1A (Standard USB protocol).
  
• Battery Specification: 3.7V 0.25A Lithium-ion.
  
• Charging Time: Approximately 2 hours for a full cycle.
  
• Operation: The device can operate wirelessly (approx. 2-3 hours) or wired.

Note: Using the device while wired ensures maximum consistent voltage to the motor, preventing RPM drops during deep needling.

4.2 Cartridge Configurations

The website offers three cartridge types, each engineered for specific hydrodynamic and mechanical interactions with the skin.

The 12-Needle Cartridge

Configuration: 12 stainless steel needles arranged in a circle.

Physics (The Fakir Effect): With fewer needles, there is greater spacing between insertion points. This results in higher pressure per needle (Force / Area).

Indication: This high-pressure configuration allows the needles to penetrate tough, fibrotic tissue such as deep acne scars (ice-pick, boxcar), surgical scars, and stretch marks. It is the “heavy artillery” of microneedling.

Risk Profile: Higher risk of pain and bleeding; requires lower speed settings to prevent tearing.

The 36-Needle Cartridge

Configuration: 36 fine needles arranged in a dense grid.

Physics: The high density of needles creates a “bed of nails” effect (Fakir effect), distributing the pressure over a larger area. This reduces the penetration force per needle, making it less painful and less likely to penetrate deep scar tissue, but highly effective for surface saturation.

Indication: General skin rejuvenation, fine lines, large pores, hyperpigmentation, and loose skin. Ideal for larger areas (cheeks, forehead, neck) where uniform coverage is priority over depth.

Risk Profile: Moderate. If moved too quickly, the dense needles can create a “slicing” effect; requires higher RPM settings.

The Nano Cartridge

Configuration: A grid of microscopic silicone or steel pyramids (nano-pins).

Physics: Non-invasive oscillation. Does not breach the dermal-epidermal junction.

Indication: Transdermal delivery of serums, treatment of delicate areas (eyelids, lips), and daily or weekly maintenance for “glow.”

Risk Profile: Very low. No downtime, no bleeding, no anesthesia required.

Nano, 12-pin, and 36-pin cartridges are designed for different cosmetic applications.

All cartridges are sterile and single-use only. Reuse or sharing of cartridges significantly increases the risk of infection and skin injury.

In a clinical setting, an aseptic field is mandatory. The home user must replicate this environment to prevent the introduction of pathogens into the open micro-channels.

5.1 Environment and Equipment Preparation

Sanitization: Select a clean, non-porous surface (e.g., countertop). Disinfect the surface with an antibacterial wipe or alcohol spray.

Mise en place: Arrange the following items:

• The Microneedling Pen (Charged).
  
• Selected Cartridge (Sealed).
  
• 70% Isopropyl Alcohol (in a small cup and a spray bottle).
  
• Cotton pads or sterile gauze.
  
• Serum (High Molecular Weight Hyaluronic Acid ONLY).
  
• Disposable gloves (Nitrile recommended).
  
• Paper towel (Clean).
  

5.2 Cartridge Sterilization Protocol

Although cartridges are supplied in sterile blister packs, a secondary sterilization step is a critical redundancy to ensure safety.

Inspect: Open the blister pack and inspect the needles. If any needle appears bent or hooked, discard the cartridge immediately.

Soak: Pour 70% Isopropyl Alcohol into a small cup. Dip the needle tip of the cartridge into the alcohol and let it soak for 1-2 minutes.

Note: Use 70% alcohol, not 99%. The water content in 70% alcohol is required to penetrate the cell walls of bacteria and denature their proteins effectively. 99% alcohol evaporates too quickly to ensure sterilization.

Dry: Remove the cartridge and allow it to air dry completely (approx. 1 minute) on a clean paper towel. Alcohol residue can sting and irritate the skin.

5.3 Skin Decontamination

The skin surface must be surgically clean. Makeup residue, sunscreen, or surface bacteria pushed into the dermis can cause granulomas (foreign body reactions) or infection.

Double Cleanse:

• Step 1: Use an oil-based cleanser or balm to dissolve makeup, SPF, and sebum.
  
• Step 2: Follow with a gentle, pH-balanced foaming cleanser to remove residue. Rinse thoroughly with warm water.

The Alcohol Wipe (Defatting):

• Saturate a cotton pad with 70% Isopropyl Alcohol.
  
• Wipe the entire treatment area firmly. This step removes the lipid barrier and kills resident bacteria. It may sting, but it is non-negotiable for safety.
  

Numbing (Optional):

If using a topical anesthetic (5% Lidocaine), apply a thick layer and leave for 20-30 minutes.

CRITICAL: You must completely remove the numbing cream before needling. Wipe the skin with alcohol again to ensure no cream enters the micro-channels, which could cause systemic toxicity or severe irritation.

This section details the step-by-step operation of the device, integrating the manufacturer’s instructions with clinical best practices.

6.1 Device Assembly and Setup

Mounting the Cartridge:

• Identify the slot on the top of the pen.
  
• Insert the sterilized cartridge into the slot.
  
• Twist the cartridge clockwise into the locking bayonet until a firm click or resistance is felt. This ensures the cartridge cannot eject during high-speed oscillation.

Adjusting Needle Length:

• Locate the Adjustor Ring (graduated depth dial).
  
• Rotate the ring until the desired depth aligns with the indicator mark.
  
• Always visually confirm needle extension before contacting skin, as mechanical tolerance may vary between units.

Powering On:

• Press and hold the Power button for 2–3 seconds.
  
• The device will start at the lowest speed setting.
  
• Short-press the button to cycle through speed levels (typically 1–5 or 1–6 depending on model).

6.2 Glide Medium (Slip Agent Requirement)

Microneedling on dry skin is unsafe and can cause tearing or scratching.

Recommended:

• High Molecular Weight Hyaluronic Acid (HA) only.
  
• Non-immunogenic, hydrating, and compatible with open micro-channels.

Prohibited:

• Vitamin C (L-Ascorbic Acid)
  
• Retinoids
  
• Exfoliating acids (AHA/BHA)
  
• Thick creams or oils

Introducing reactive ingredients into the dermis may cause granulomas, chemical burns, or prolonged inflammation.

Two distinct techniques may be used depending on cartridge type, depth, and treatment area.

Technique A: Stamping (Safety Standard)
