Microneedling: Side Effects, Safety and Results 

Microneedling–does it really work? In this post, we’re diving deep into the world of the popular cosmetic procedure that promises skin rejuvenation, treats scars and even restores hair. We’ll explore the benefits, potential side effects and expected results to help you decide if microneedling is right for you.

Microneedling Explained

Microneedling, also known as collagen induction therapy, is a minimally invasive cosmetic procedure that harnesses the power of your body’s natural healing mechanisms to promote younger-looking, healthier skin. Here’s a closer look at how it works:

Tiny Needles, Big Results

Microneedling is performed using a specialized device equipped with numerous fine needles. During the procedure, these needles create controlled, miniscule punctures in the uppermost layer of your skin, the epidermis. These micro-injuries send a signal to your body. It perceives these punctures as minor wounds that need repair, triggering a cascade of healing responses within your skin.

The Collagen Boost

Collagen is a protein that provides structure and elasticity to your skin. As we age, collagen production naturally declines, leading to wrinkles, fine lines and a loss of firmness. Microneedling stimulates the fibroblasts, the collagen-producing cells in your skin, to ramp up production, resulting in a plumper, more youthful appearance.

In addition to collagen, microneedling also promotes the production of elastin. Elastin is another essential protein that gives your skin its elasticity, allowing it to snap back after stretching or movement. Increased elastin production contributes to smoother, tighter skin with a more youthful look.

Beyond the Surface

While microneedling primarily targets the epidermis, the micro-injuries can also extend slightly into the dermis, the deeper layer of your skin. This deeper penetration may further enhance collagen and elastin production and potentially improve the absorption of skin care products applied after treatment.

Benefits of Microneedling

Now that we understand how microneedling impacts the body on a cellular level, let’s delve into its visible effects on common skin concerns.

Reduced Appearance of Scars

Microneedling can improve the appearance of acne scars, stretch marks and surgical scars by promoting collagen production and encouraging new skin cell growth. It’s particularly effective for treating atrophic scars, which have a sunken or pitted appearance.

Diminished Fine Lines and Wrinkles: 

By stimulating collagen and elastin, microneedling can help soften the appearance of fine lines and wrinkles, leading to smoother, firmer skin.

Improved Skin Texture and Tone

Microneedling can address uneven skin tone, hyperpigmentation (dark spots) and large pores, resulting in a more even and radiant complexion.

Potential Benefits for Hair Loss 

Microneedling may stimulate hair growth in individuals with alopecia by increasing blood flow to the scalp and promoting a healing environment.

What are the Side Effects of Microneedling?

Microneedling is a safe and well-tolerated procedure. However, like any medical procedure, it can cause some temporary side effects. Here’s a breakdown of the most common ones and how to manage them:

Skin Irritation

Redness, swelling and mild discomfort are the most common side effects following microneedling. These typically appear within the first 24 hours and usually subside within 1-3 days. Soothing products with ingredients like aloe vera or calamine lotion can help alleviate discomfort. A cool compress can also be applied to reduce swelling.

Pinpoint Bleeding

There’s a chance of experiencing pinpoint bleeding immediately after the procedure. This usually resolves on its own within a few minutes. Applying gentle pressure with a sterile gauze pad can help control any bleeding.

Uneven Skin Tone

Temporary hyperpigmentation, or darkening of the skin, is a potential side effect, especially for individuals with darker skin tones. This occurs when the skin produces excess melanin in response to the micro-injuries. (We’ll cover more about this later on.)

Risk of Infection and Allergic Reaction

Microneedling involves creating punctures in the skin, so proper hygiene is key. Always ensure your dermatologist uses sterile equipment and adheres to strict hygiene protocols during the procedure.

And while rare, some individuals may experience an allergic reaction to the topical numbing cream used during the procedure. If you have any allergies, discuss them with your provider beforehand.

What to Expect From Your Microneedling Treatment 

A typical microneedling session at a med spa involves the following steps:

Consultation

First, your provider–ideally a licensed aesthetician, board-certified dermatologist or other expert–will assess your skin type, concerns and medical history to determine if microneedling is suitable for you. If you decide to go ahead with treatment, it can usually be performed on the same day.

Procedure

First, the treatment area is thoroughly cleansed to minimize the risk of infection. A topical numbing cream may be applied to enhance comfort during treatment. Then, your provider will use a sterile microneedling device to create controlled punctures all over the treatment area. If you’re getting any topical add-ons such as serums or PRP, they’ll then be applied.

Recovery

Microneedling typically involves a few days of downtime. Here’s what to expect during the healing process:

  • Days 1-2: You might experience redness, swelling, and a feeling similar to sunburn. This is normal and can be managed with cool compresses.
  • Days 3-7: The redness and swelling typically subside, but some flaking or peeling may occur. Avoid picking at your skin and let it shed naturally.
  • Weeks 2-4: The skin continues to heal and regenerate collagen. You might start noticing a subtle improvement in texture and tone.
  • Months 2-3: Optimal results become more evident as collagen production reaches its peak. You can expect smoother, firmer skin with improved elasticity and reduced appearance of wrinkles, scars or enlarged pores.

Results

Microneedling results are gradual and improve over time. While you’ll see a brighter, smoother complexion within a few weeks, the full benefits typically take 2–3 months to become evident. Expect to notice benefits like:

  • Improved skin texture and tone 
  • Faded fine lines and wrinkles 
  • Brighter complexion
  • A boost in skin firmness and elasticity
  • Lightened acne scars and stretch marks 
  • Increased skin care product absorption

Aftercare Tips for a Smooth Recovery

To optimize healing and results, here’s how to nurture your newly renewed skin.

  • Gentle Touch: Throughout the healing process, pamper your skin with fragrance-free cleansers and gentle moisturizers. Avoid harsh scrubs or products that could irritate.
  • Sun Protection is Key: Your freshly regenerated skin is more susceptible to sun damage. Apply sunscreen with SPF 30 or higher daily to shield your progress.
  • Sweat Less, Heal More: Give your skin a break from intense exercise for at least 24 hours after treatment. Sweating can irritate the micro-wounds and hinder healing.
  • Let Your Skin Breathe: Avoid the temptation to pick or scrub during any peeling that occurs. This is a natural part of the healing process. Let your skin shed flakes on its own.
  • Pause the Makeup: To prevent irritation,  resist the urge to wear makeup for at least 24 hours after treatment. Allow your skin to recover comfortably.
  • Hold Off on Harsh Actives: Put harsh products like retinol and exfoliants on hold until your skin heals completely. These can irritate the micro-wounds and disrupt healing.
  • Relax and Avoid Heat: For at least a week after treatment, avoid hot tubs, saunas, and excessive sun exposure. These can irritate your skin and hinder healing.

Microneedling for Different Skin Types

Microneedling is a versatile treatment suitable for most skin types. However, a customized approach is key to ensure optimal results and minimize potential side effects. Here’s a breakdown of considerations for different skin types:

  • Dry Skin: Individuals with dry skin can benefit from microneedling, but proper hydration is key before, during and after treatment. Hyaluronic acid serums applied post-procedure can further enhance results.
  • Oily Skin: Microneedling can help regulate oil production and minimize enlarged pores. However, those with active acne may not be ideal candidates. Consulting a dermatologist is essential to determine if microneedling is suitable for your specific acne condition.
  • Sensitive Skin: Sensitive skin may be more prone to irritation after microneedling. A dermatologist can recommend a shallower needle depth and recommend calming skin care products to minimize discomfort.

Is Microneedling Safe for All Skin Tones?

Microneedling is generally considered a safe option for all skin tones when performed correctly by a qualified professional. Here’s what makes it a good choice for many:

Unlike laser treatments that can target pigment in the skin and potentially cause post-inflammatory hyperpigmentation (PIH) in darker skin tones, microneedling relies on physical stimulation to trigger collagen production, reducing the risk of unwanted pigmentation.

It also allows for customization based on skin type. With proper technique and shallower needle depths, dermatologists can effectively treat darker skin tones while minimizing the risk of complications.

However, it’s important to note that certain precautions are necessary. While the risk is lower than with some other procedures, microneedling can still trigger PIH, especially in darker skin tones. A provider experienced in treating diverse skin tones can best determine if microneedling is right for you and set the treatment parameters correctly.

Who Shouldn’t Get Microneedling?

Microneedling is a powerful tool for skin rejuvenation, but it’s not suitable for everyone. Here are some key contraindications to consider before undergoing this treatment:

  • Active Skin Conditions: If you have active acne outbreaks, eczema, psoriasis or other uncontrolled inflammatory skin conditions, microneedling could worsen the irritation.
  • Bleeding Disorders or Blood Thinners: Microneedling can cause minor bleeding. People with bleeding disorders or those taking blood-thinning medications may not be suitable candidates.
  • Keloids or Raised Scars: Microneedling can stimulate the formation of scar tissue. If you have a history of keloids or raised scars, this treatment may worsen their appearance.
  • Weakened Immune System: Due to the creation of micro-injuries, microneedling carries a slight risk of infection. Those with weakened immune systems may be more susceptible.
  • Pregnancy or Breastfeeding: The safety of microneedling during pregnancy or breastfeeding is not fully established. It’s best to wait until after giving birth and stopping breastfeeding.

Microneedling at Home vs. In-Office: Weighing Your Options

Microneedling can be performed by a dermatologist or aesthetician in an office setting or with at-home microneedling devices (dermarollers). Here’s a breakdown of the pros and cons:

In-office microneedling procedures are performed by a certified professional, offering deeper needle penetration for potentially greater results and lower risk of complications. However, it’s usually more expensive than at-home kits.

Conversely, at-home microneedling is more affordable and convenient. But the needle depth is typically shallower, potentially limiting results, and there’s a higher risk of side effects if not done carefully.

Takeaway

Microneedling offers a safe and effective approach to improve various skin concerns. By understanding the benefits, potential side effects and proper aftercare, you can make an informed decision about whether microneedling is right for you. With a customized treatment plan from a board-certified dermatologist, you can achieve a smoother, more youthful and radiant complexion.
