What Is Microneedling and How Does It Actually Work?

Key Takeaways

• Microneedling is a minimally invasive skin treatment that uses very fine needles to make tiny, controlled openings in the skin.
• These small openings trigger the skin's natural healing response, which leads to new collagen and elastin over time.
• Microneedling benefits include smoother texture and a softer look to fine lines, wrinkles, acne scars, and enlarged pores.
• Scarlet RF microneedling adds radiofrequency energy for extra skin tightening, and results from either option build over several sessions.
• Renu Laser & Skin Care offers both standard and Scarlet RF microneedling in Littleton, CO, so request an appointment at Renu Laser & Skin Care to find out which option fits your skin goals.

What Is Microneedling?

Many people have heard of microneedling, but fewer know what actually happens during a session. In simple terms, microneedling is a skin treatment that uses a device with very thin needles to create tiny holes in the top layer of the skin.

That may sound strange, but the goal is not to harm the skin. The goal is to 'wake up' the skin's repair system. Microneedling is also called collagen induction therapy, which means a treatment that encourages the body to make more collagen.

According to the Cleveland Clinic overview of microneedling, most people get microneedling on their face, but it can also be used on the neck, back, legs, and other areas with damaged or aging skin.

At Renu Laser & Skin Care, microneedling is one of several anti-aging treatments at the Littleton med spa, alongside options like chemical peels, laser treatments, and HydraFacials.

How Does Microneedling Work? The Skin's Natural Healing Response

To understand how microneedling works, it helps to think about how your skin heals a small scrape. Your body notices the injury, sends in repair cells, and builds new tissue. Microneedling uses that same process on purpose, in a careful and controlled way.

Here is what happens, step by step:

1. The skin is prepared. The provider cleans the skin. Many providers also apply a numbing cream first.
2. Tiny channels are created. A handheld device with fine needles makes very small, shallow openings across the treatment area.
3. The healing response begins. The skin treats these openings as minor injuries and starts repairing them.
4. New collagen and elastin form. Over the following weeks and months, the skin builds fresh support proteins as part of the repair process.
5. Skin gradually looks smoother and firmer. As new collagen settles in, texture, tone, and fine lines can improve.

Because the openings are so small, they close quickly. The deeper benefits come from the repair work that happens afterward.

The Role of Collagen and Elastin in Skin Rejuvenation

Collagen and elastin are two proteins that act like the skin's support system.

• Collagen gives skin its structure and firmness. You can think of it as the frame that holds skin up.
• Elastin lets skin stretch and bounce back into place, like a rubber band.

The Cleveland Clinic explanation of collagen notes that your body makes less collagen as you age, and the collagen you already have breaks down faster. Too much sun can also lower collagen production and speed up its breakdown.

When collagen and elastin drop, skin can start to look thinner, looser, and more lined. Microneedling helps by prompting the skin to make more of both proteins. This is why microneedling is often described as skin rejuvenation, which simply means helping skin look fresher and healthier.

Microneedling Benefits: Common Skin Concerns It Can Improve

Microneedling is popular because it can address many concerns with one treatment. The American Academy of Dermatology (AAD) guide to microneedling lists concerns dermatologists use it for, including: 

• Acne scars
• Dark spots
• Large pores
• Sagging skin
• Scars from surgery or injury
• Stretch marks
• Uneven skin texture and tone
• Wrinkles and fine lines

The AAD also notes that microneedling is minimally invasive and safe for all skin tones.

At Renu Laser & Skin Care, microneedling is used to help reduce the look of fine lines, wrinkles, acne scars, and enlarged pores. Patients focused on breakouts and scarring can also learn more about acne and acne scar treatments at Renu.

Standard Microneedling vs. Scarlet RF Microneedling

Renu Laser & Skin Care offers two types of microneedling. Both use fine needles, but Scarlet RF microneedling adds radiofrequency (RF) energy. Radiofrequency is a type of energy that gently heats the deeper layers of the skin.

The AAD explains that adding heat through the needles can increase the body's ability to produce collagen, which may improve results.

Neither option is 'better' for everyone. The right choice depends on your skin type, your main concerns, and your goals.

What a Typical Microneedling Treatment Plan Looks Like

Microneedling is not usually a one-time treatment. Collagen takes time to build, so results show up gradually.

The Cleveland Clinic notes that most people need multiple treatments, usually about 3 to 8 weeks apart, and that it can take 3 to 6 months to see results. After that, you might need one maintenance session a year.

A typical plan at Renu Laser & Skin Care often includes:

• A consultation to review your skin, health history, and goals
• A series of sessions spaced out to give your skin time to heal and rebuild
• Aftercare guidance such as sun protection and gentle skin care between visits
• Optional pairing with other treatments, such as a custom facial or LED therapy, when it fits your plan

Your provider will help set a schedule that matches your skin and your goals.
