Microneedling has become one of the most popular skin treatments in the country, and for good reason. It addresses a wide range of common concerns, from acne scars to fine lines to uneven texture, with little downtime and natural-looking results. But with that popularity has come a flood of medspas, at-home devices, and conflicting information, which makes it hard to know what microneedling can actually do and where to have it done safely.

At Thomas Dermatology, we want patients across Las Vegas and Henderson to make confident, well-informed decisions about their skin. This guide explains what microneedling is, what it treats, what results to realistically expect, and why having it performed by a qualified provider makes a real difference.

What Is Microneedling?

Microneedling, sometimes called collagen induction therapy, is a minimally invasive treatment that uses a device with very fine, sterile needles to create tiny, controlled micro-injuries in the skin. These micro-injuries are so small they are barely perceptible, but they trigger something powerful: your body’s natural healing response.

When the skin senses these micro-channels, it ramps up production of collagen and elastin, the two proteins most responsible for keeping skin firm, smooth, and youthful. As that new collagen builds over the following weeks, the skin becomes smoother, firmer, and more even in tone and texture.

The beauty of microneedling is that it works with your own biology. Rather than introducing anything foreign, it simply prompts your skin to repair and rebuild itself. That is why results tend to look so natural and continue to improve over time.

What Does Microneedling Treat?

One reason microneedling has become so widely used is its versatility. It can meaningfully improve a range of concerns, including:

Acne scars. Microneedling is one of the most effective non-surgical treatments for the textured, pitted scars left behind by acne. By rebuilding collagen in the scarred area, it helps smooth the skin over a series of treatments. If acne scarring is your main concern, our Acne Scars page covers the full range of options.

Fine lines and wrinkles. By boosting collagen, microneedling can soften early fine lines and improve overall skin firmness, especially around the eyes, mouth, and forehead.

Uneven skin texture. Rough, bumpy, or uneven skin often becomes noticeably smoother after a series of treatments.

Enlarged pores. Microneedling can help pores appear smaller by improving the structure and firmness of the surrounding skin.

Overall skin tone and radiance. Many patients notice brighter, healthier-looking skin as new collagen develops.

For patients who want even more dramatic results on deeper wrinkles, significant laxity, or stubborn scarring, radiofrequency microneedling combines the collagen-building benefits of traditional microneedling with radiofrequency energy for an added tightening effect.

Microneedling vs Chemical Peels: Which Is Right for You?

Patients often ask whether they should choose microneedling or a chemical peel. The honest answer is that they do different things, and the right choice depends on your skin and your goals.

Microneedling works primarily on the structure of the skin, rebuilding collagen to improve texture, scarring, and firmness from within. It is especially strong for acne scars and texture concerns.

Chemical peels work primarily on the surface of the skin, using a solution to exfoliate the top layers and reveal fresher skin underneath. They are particularly effective for tone concerns like sun damage, brown spots, and dullness. You can read more on our Chemical Peels page.

For many patients, the best results come from a customized plan that may combine both treatments over time. This is exactly the kind of decision where a board-certified dermatologist adds real value, because the recommendation is based on a true understanding of your skin rather than a one-size-fits-all package.

What to Expect During and After Treatment

Knowing what the experience is actually like helps set realistic expectations.

Before treatment. Your provider will assess your skin and discuss your goals. A numbing cream is typically applied beforehand so the treatment is comfortable.

During treatment. The microneedling device is moved across the treatment area. Most patients feel only mild pressure or a light prickling sensation thanks to the numbing cream. A typical session takes around 30 to 60 minutes depending on the area.

Immediately after. It is normal for the skin to look pink or flushed, similar to a mild sunburn, for a day or two. Some patients experience slight swelling or sensitivity, which resolves quickly.

The days that follow. Skin may feel slightly rough or dry as it heals, and some light flaking can occur. Most patients return to normal activities right away, with the visible pinkness fading within a couple of days.

Results. Because microneedling works by building new collagen, results develop gradually over several weeks and continue improving. Most patients need a series of treatments, often spaced a few weeks apart, for the best outcome. Your provider will recommend a plan tailored to your goals.

After treatment, protecting your skin from the sun is especially important, since freshly treated skin is more vulnerable to UV damage. Diligent sunscreen use helps protect your results and your skin health.

Why a Board-Certified Dermatologist Matters for Microneedling

Microneedling is widely available, but not all microneedling is equal. Because the treatment involves creating controlled injuries in the skin, the training, technique, equipment, and hygiene standards of your provider matter enormously, both for your safety and your results.

Having microneedling performed in a board-certified dermatology practice means medical-grade equipment and strict sterilization, providers who understand skin at a clinical level and can recognize how your unique skin will respond, the ability to combine microneedling with other evidence-based treatments as part of a real plan, and proper handling if any concern arises. It also means honest guidance about whether microneedling is even the right treatment for you in the first place, rather than a sales pitch.

For patients with darker skin tones, certain active skin conditions, or a history of specific skin issues, this clinical oversight is especially important, since the wrong approach can lead to complications that a trained dermatologist knows how to avoid.

Frequently Asked Questions

How much does microneedling cost in Las Vegas?

The cost of microneedling depends on the treatment area, the number of sessions in your plan, and whether traditional or radiofrequency microneedling is recommended for your goals. Because every patient’s plan is different, the best step is a consultation where we can assess your skin and provide tailored guidance.

How many microneedling sessions will I need?

Most patients need a series of treatments, often spaced a few weeks apart, for the best results. The exact number depends on your concern and your goals. Acne scarring, for example, typically requires more sessions than general skin texture improvement.

Is microneedling painful?

Most patients find microneedling very tolerable. A numbing cream is applied beforehand, so the sensation is usually limited to mild pressure or light prickling during the treatment.

How long is the downtime after microneedling?

Downtime is minimal. Most patients experience pinkness similar to a mild sunburn for a day or two, and many return to normal activities right away. Visible redness typically fades within a couple of days.

When will I see results from microneedling?

Because microneedling works by stimulating new collagen, results develop gradually over several weeks and continue to improve. Most patients see the best results after completing a series of treatments.

Is microneedling better than a chemical peel?

Neither is universally better. They address different concerns. Microneedling improves texture, scarring, and firmness from within, while chemical peels improve tone and surface concerns like sun damage. A dermatologist can help you decide which is right, or whether a combination would serve you best.
