What Is Microneedling and How Does It Work?

Teresa Hernandez, MSN FNP-BC·11 min read·Aesthetics·Summerlin, Las Vegas, NV

Microneedling has gained popularity for good reason — it works with your biology, not against it. Here's what it actually is, how it triggers real structural change in your skin, and what the process looks like at a medical clinic in Las Vegas.

What Is Microneedling?

Microneedling — also called percutaneous collagen induction therapy — is a cosmetic procedure that uses a pen-like device fitted with very fine needles to create controlled micro-channels through the outer layer of skin and into the upper dermis. These micro-injuries aren't random damage. They're a calibrated signal that tells your body to activate its repair machinery, producing new collagen and elastin in the treated area.

Over the following weeks, this process gradually improves skin texture, firmness, and the appearance of scars and wrinkles. It's a form of skin rejuvenation that relies on your own biology rather than synthetic fillers or surface-level exfoliation.

At Body Balance Medical, microneedling is performed in-office by licensed medical providers using FDA-cleared, motorized devices with adjustable needle depth — not manual derma roller tools. Needle diameters typically range from 0.1 to 0.25 mm, with depths adjusted based on the area being treated and the concern being addressed.

A typical session runs about 30–45 minutes of active needling, plus additional time for numbing and prep. Most people require a series of treatments rather than a single visit to reach their desired results.

This article covers standard microneedling. Advanced options — like microneedling combined with PRF or PDGF growth factors — are covered in separate articles on PRF microneedling and Body Balance Medical's Ariessence PDGF blog.

How Microneedling Works: The Science in Plain Language

Microneedling taps into the skin's normal wound-healing process to rebuild collagen in a controlled, predictable way. No thermal energy. No ablation. Just a mechanical trigger that your body already knows how to respond to. Here's what happens when the thin needles pass over your skin:

Collagen production naturally declines starting in the mid-20s. Periodic microneedling treatment can help offset that decline without removing or burning the skin surface the way laser resurfacing or deeper chemical peels do.

Unlike energy-based devices, standard microneedling doesn't deliver heat — which means lower risk of pigmentation changes across many skin tones, including darker skin tones. That said, laser treatments and microneedling each have distinct roles, and the right choice depends on what you're treating. A healthcare provider can help sort that out.

What Skin Concerns Can Microneedling Help With?

Microneedling is versatile. It can be used on the face, neck, décolletage, and select body areas for a range of textural and pigment-related skin conditions. Common indications include:

• Acne scars: Boxcar and rolling scars often respond well. Studies show 51–60% improvement in scar appearance over 3–6 sessions. Deeper ice-pick scars typically need additional modalities like subcision. Active acne must be under good control before starting — treating inflamed skin with needles creates more problems than it solves.
• Fine lines and wrinkles around the eyes, mouth, and forehead
• Enlarged pores and overall texture irregularities
• Stretch marks and certain surgical scars
• Uneven skin tone, including some forms of skin discoloration, dark spots, and sun damage — though not every pigment issue is appropriate for needling
• Mild skin laxity — microneedling supports tightening sagging skin to a degree, though significant sagging skin may require other interventions

Microneedling may also be used on the scalp for hair loss protocols, though this remains an off-label cosmetic use that should be discussed in detail with a provider.

During a visit at Body Balance Medical, the provider evaluates skin type, primary concerns, and medical history to determine whether microneedling is appropriate — or whether another aesthetic option would be safer or more effective for your certain skin conditions.

What to Expect During a Microneedling Procedure at Body Balance Medical

Here's what a typical in-office microneedling procedure looks like from arrival to departure at our Las Vegas clinic — no surprises, no ambiguity.

• Skin evaluation and baseline photography for before/after comparison
• Review of recent medications (isotretinoin, blood thinners, topical retinoids)
• Discussion of target areas and realistic goals with the provider

• The skin is thoroughly cleansed
• A numbing cream (topical anesthetic) is applied and left on for 20–30 minutes
• Once numbness sets in, the provider performs the microneedling with a motorized pen in multiple passes at tailored depths across each zone
• What you'll feel: Pressure, vibration, and a light scratching sensation — not sharp pain. Bony areas like the forehead and jawline tend to feel more noticeable than the cheeks.

Mild pinpoint bleeding and oozing are normal and are gently cleaned during the session. A soothing barrier product is typically applied afterward. The provider reviews basic aftercare instructions before you leave — for the full step-by-step on cleansing, product use, and makeup timing, see Body Balance Medical's dedicated microneedling aftercare article.

Does Microneedling Hurt and What Is Recovery Like?

Does microneedling hurt? Most patients describe it as uncomfortable rather than painful once the numbing cream has taken effect. The forehead and upper lip tend to be more sensitive; the cheeks and jawline are usually milder. Needle depth is adjusted by the provider to balance comfort and results.

This is minimal downtime by most standards.

• Brief pinpoint bleeding during treatment — normal
• Mild tightness and dry skin — expected; use a hydrating moisturizer as directed
• Persistent heavy bleeding or spreading rash — call the clinic
• Pus-filled bumps or severe pain days later — not expected; contact your provider

Strict sunscreen use while the skin heals is non-negotiable. Detailed product and timing guidance is available in Body Balance Medical's separate microneedling aftercare article — reference it before your first session.

Professional Microneedling vs. At-Home Derma Rollers

You've seen derma roller tools online for under $30. Here's why professional microneedling at a medical clinic isn't the same thing. At-home derma rollers typically use shorter, often duller needles — around 0.25 mm — at a fixed depth. They provide superficial exfoliation and may slightly improve absorption of skin care products, but they lack the depth to trigger meaningful collagen stimulation.

Any of these home-use risks can trigger infection, hyperpigmentation, or permanent scarring. For meaningful improvements in acne scars, deeper wrinkles, or stretch marks, patients in Las Vegas, Henderson, and Summerlin will get safer, more predictable results in experienced hands at a clinic like Body Balance Medical — not from a $20 tool on a bathroom counter.

Treatment Plans, Results Timeline, and Safety Considerations

Microneedling results build gradually. This is biology, not a filter — and the outcomes depend on the number of sessions, spacing, and what you're treating.

• Improving skin texture or reducing fine lines: 2–3 sessions may be sufficient
• Moderate acne scars or stretch marks: 3–6 sessions spaced about 4–6 weeks apart
• More established scarring: additional sessions, possibly combined with other treatments

Early changes — smoother overall texture, subtle firmer skin — often appear within 2–4 weeks. More visible improvement in fine lines or scars typically shows after multiple sessions, with continued remodeling for up to 6–12 months as collagen matures. Maintenance treatments may be recommended to support ongoing results.
