Comparing Types of Microneedling: CIT, PCI and Automated Methods

Understanding Microneedling

Microneedling is a minimally invasive cosmetic procedure that involves pricking the skin with tiny needle pins. It aims to stimulate collagen production and skin regeneration for various anti-aging and skin rejuvenation benefits. There are several types of microneedling suitable for different treatment goals.

How Microneedling Works

During microneedling, a board-certified dermatologist uses a specialized device equipped with superfine needles to create tiny punctures in the skin. This triggers the body to produce new collagen and elastin while releasing growth factors that boost healing.

Though it seems counterintuitive to puncture skin for rejuvenation, the controlled micro-injuries kickstart natural repair processes for smoother, firmer, more youthful skin.

Major Types of Microneedling

There are three major varieties of microneedling currently used in aesthetic medicine:

1. Collagen induction therapy
2. Percutaneous collagen induction
3. Automated micro-needling

While procedures are similar, depth of needle penetration, precise techniques, and incorporated skin treatments differ.

Collagen Induction Therapy

Collagen induction therapy (CIT), also called dermarolling or skin needling, was the first type of skin microneedling. It involves rolling a device with hundreds of fine protruding needles over skin areas requiring treatment.

The needle length typically ranges between 0.5 mm and 2.5 mm. Shorter needles treat superficial skin layers while longer ones reach deeper dermal levels. The optimal needle size depends on the targeted skin concerns.

Ideal for:

• Reducing appearance of fine lines and wrinkles
• Improving mild acne scars
• Enhancing absorption of topical skincare products

Percutaneous Collagen Induction

Percutaneous collagen induction (PCI) uses a specialized tool tipped with 12 to 42 smaller needles puncturing skin at various controlled depths. Combining needles of different projections allows for customized targeting of both superficial and deep treatment zones in one session.

The device gently taps over skin in a stamping motion versus rolling. This percussive technique may pose less damage risk compared to dragging of traditional plastic dermarollers.

Ideal for:

• Lessening appearance of deep wrinkles and creases
• Smoothing pitted acne scars
• Tightening and rejuvenating neck and dcolletage areas

Automated Micro-Needling

Automated micro-needling devices use an electronic motor to repeatedly insert and retract the needle tip. This enhances precision and minimizes damage by eliminating manual human movement.

The automated puncturing action also allows needles to reach deeper layers. Along with needle depth adjustments, the speed, pressure, and frequency settings are customizable based on patient needs.

Ideal for:

• Minimizing severe acne pockmarks
• Plumping hollow under eye areas
• Overall skin tightening and rejuvenation

Comparing Microneedling Techniques

While all microneedling methods essentially puncture skin for regeneration, some key differences exist:

Depth of Penetration

CIT devices have shorter needle lengths reaching up to 2 mm depth. PCI tools combine short and longer needles up to 3 mm. Automated devices plunge needles deeper to 3-4 mm levels.

Treatment Precision

Automated micro-needling allows the most precision and customization. Manual rollers rely solely on user control and technique. PCI falls in the middle with some adjustability combined with human skill.

Bleeding and Downtime

More aggressive techniques cause greater trauma and typically more pinpoint bleeding. Automated micro-needling usually leads to most downtime post-treatment due to depth reached.

Results Timeline

While all methods stimulate collagen over time, deeper penetration triggers longer-lasting improvements. However, best approach still depends on individuals specific skin goals and conditions.

Candidate Skin Types

With precise depth adjustments, any skin type can benefit from some form of microneedling. However, more aggressive techniques may not suit highly sensitive skin prone to scarring.

What to Expect During Microneedling

The steps for microneedling sessions generally involve:

1. Cleansing - The treatment area gets cleaned and sterilized.
2. Numbing - A topical anesthetic is applied for 30-60 minutes to maximize comfort.
3. Needling - The device rolls over skin or makes stamping motions based on type used.
4. Serum - Soothing serums containing growth factors or vitamins get massaged into punctures.
5. Healing - Treatments every 4-6 weeks continue until desired results emerge.

While feeling initial pinpricks, microneedling should not be painful with numbing. Some people compare sensations to cat scratches. After 1-3 days, redness and sensitivity generally resolve.

Microneedling Risks and Side Effects

When performed by an experienced aesthetic professional, microneedling proves very safe for most patients. However, potential side effects include:

• Mild bleeding
• Temporary redness
• Swelling
• Bruising
• Skin sensitivity for 12-48 hours

Rare risks involve irritation, infection, and scarring if aftercare directions aren't properly followed. Avoiding needling over active breakouts or cuts reduces likelihood of adverse reactions.

Takeaways on Microneedling Variations

In the hands of a trusted skin expert, all types of microneedling offer rejuvenation without extended recovery. Lighter therapies like CIT pose less downtime and risks while still improving texture.

Deeper automated micro-needling elicits longest-lasting tissue regeneration but requires more healing time. Understanding differences allows determining best match for your particular skin.
