Microneedling has become one of the most popular treatments for improving skin texture, acne scars, fine lines, and overall skin quality—and for good reason. Unlike treatments that simply improve the appearance of the skin temporarily, microneedling works by stimulating your skin’s own natural repair process and encouraging the production of new collagen.
At Rangel Dermatology in Miami, we offer microneedling both alone and in combination with platelet-rich plasma (PRP) for patients looking to improve the health, texture, and appearance of their skin with relatively minimal downtime.
What Is Microneedling?
Microneedling, sometimes called collagen induction therapy, is a minimally invasive treatment that uses very fine, sterile needles to create thousands of controlled microscopic channels in the skin.
While creating tiny injuries in the skin may sound counterintuitive, these micro-injuries are precisely what make the treatment effective. They trigger the skin’s natural wound-healing response, stimulating fibroblasts and signaling the production and remodeling of collagen and elastin—two proteins that are essential for smooth, firm, healthy-looking skin.
As we age, collagen production naturally declines. Sun exposure, acne, inflammation, and environmental damage can also affect the structure and texture of our skin. Microneedling essentially encourages the skin to enter a controlled repair process, gradually replacing and remodeling damaged collagen.
The result is not an overnight transformation. Instead, skin quality continues to improve in the weeks and months following treatment as new collagen develops.
What Are the Benefits of Microneedling?
One of the reasons I like microneedling is its versatility. Rather than targeting only one specific concern, it can improve several aspects of skin quality at the same time.
Microneedling may help improve:
- Acne scars, particularly depressed or atrophic acne scars
- Uneven or rough skin texture
- Fine lines and early wrinkles
- Enlarged or visible pores
- Mild skin laxity
- Uneven skin tone
- Overall skin smoothness and radiance
For patients who feel that their skin looks dull, uneven, or simply less smooth than it used to, microneedling can also be an excellent option for overall skin rejuvenation.
Microneedling for Acne Scars
Acne scarring is one of my favorite reasons to use microneedling.
Many acne scars develop because inflammation from acne damages collagen within the skin. When the skin heals with insufficient or disorganized collagen, it can leave behind depressed scars.
Microneedling creates controlled micro-injuries within these areas, encouraging the skin to remodel old scar tissue and produce new collagen. With a series of treatments, this can gradually soften the edges and depth of certain acne scars and create a smoother skin surface.
Not every acne scar is the same, however. Rolling scars, boxcar scars, and ice-pick scars often require different approaches. Some patients benefit from microneedling alone, while others may achieve better results from a combination treatment plan that includes procedures such as subcision, chemical peels, or other scar treatments.
This is why evaluating the type of acne scar is just as important as choosing the treatment itself.
What Is Microneedling With PRP?
Microneedling can also be combined with platelet-rich plasma, or PRP.
PRP is prepared from a small sample of your own blood. The blood is processed to concentrate platelets, which contain numerous growth factors and signaling proteins involved in tissue repair and healing.
During a microneedling with PRP treatment, the microneedling device creates microscopic channels in the skin, and the PRP is applied as part of the treatment.
The goal is to combine the collagen-stimulating effects of microneedling with the regenerative growth factors found within your own platelets.
Patients sometimes hear this treatment referred to as a “vampire facial,” although I much prefer the term microneedling with PRP!
Microneedling vs. Microneedling With PRP: Which Is Better?
Both can be excellent treatments.
Traditional microneedling already stimulates a powerful wound-healing and collagen-remodeling response on its own. Adding PRP introduces concentrated platelets and growth factors derived from your own blood to complement that process.
Whether PRP is worthwhile depends on your skin, your treatment goals, and your budget. During your consultation, we can determine whether traditional microneedling or microneedling with PRP makes the most sense for you.
What Happens During a Microneedling Treatment?
Before treatment, a topical numbing medication is typically applied to make the procedure more comfortable.
Once the skin is cleansed and prepared, a professional microneedling device is passed over the treatment area. The needle depth can be adjusted depending on the area being treated, your skin, and the concern we are targeting.
For example, treating deeper acne scars may require a different approach than treating someone primarily interested in improving overall skin texture and radiance.
If PRP is being incorporated, a small amount of blood is drawn and processed to isolate the platelet-rich portion before it is used during the treatment.
What Is the Downtime After Microneedling?
Microneedling has relatively limited downtime compared with more aggressive resurfacing procedures.
Immediately afterward, most patients experience redness, warmth, and mild swelling similar to a sunburn. The skin may feel tight or sensitive, and some dryness or light flaking can develop over the following several days.
For the first few days, I recommend keeping skincare very simple. This generally means a gentle cleanser, moisturizer, and careful sun protection while avoiding potentially irritating ingredients such as retinoids and exfoliating acids.
Makeup can generally be resumed after approximately 24–48 hours, while active skincare ingredients are typically restarted around 5–7 days after treatment once the skin has recovered.
When Will I See Results From Microneedling?
Some patients notice that their skin looks brighter and more refreshed within approximately one to two weeks.
The more important changes, however, happen below the surface.
Collagen production and remodeling take time. Improvements in texture, fine lines, and acne scars generally develop gradually over the following weeks to months.
This is one reason I remind patients that microneedling is not really an “instant gratification” treatment. The goal is to stimulate your own skin to produce structural improvements over time.
How Many Microneedling Sessions Do I Need?
Although even one treatment can improve the appearance and feel of the skin, microneedling is usually most effective as a series of treatments.
The number of sessions depends on what we are treating.
Someone looking for general skin rejuvenation may need fewer treatments than someone with more significant acne scarring or textural changes. Treatments are typically spaced several weeks apart to give the skin adequate time to heal and begin its collagen-remodeling process between sessions.
After completing an initial series, some patients choose periodic maintenance treatments to continue supporting collagen production and skin quality.
Can Microneedling Cause Hyperpigmentation?
Any procedure that creates inflammation in the skin has the potential to trigger post-inflammatory hyperpigmentation, particularly in patients who are prone to pigment changes.
This is especially important here in Miami, where year-round sun exposure can make post-procedure sun protection more challenging—and even more important.
One advantage of microneedling is that it does not rely on heat to stimulate collagen. This can make it an appealing resurfacing option for a wide range of skin tones when appropriately selected and performed.
However, treatment technique, needle depth, pre- and post-treatment skincare, and sun protection all matter. I strongly recommend daily broad-spectrum SPF 30 or higher following treatment and avoiding significant sun exposure while the skin is healing.
Who Should Not Get Microneedling?
Microneedling is not appropriate for everyone. Treatment may need to be postponed or avoided in patients with certain conditions, including:
- Active acne or infection in the treatment area
- Active eczema, psoriasis, or dermatitis
- An active cold sore outbreak
- Significant sunburn or recent tanning
- Certain bleeding or platelet disorders
- Medications that affect bleeding or wound healing
- A history of abnormal scarring or keloids
- Certain immune conditions or significant immunosuppression
- Skin cancer within the treatment area
- Pregnancy or breastfeeding, depending on the planned treatment
It is important to discuss your medical history, medications, supplements, recent procedures, and history of cold sores with your dermatologist before treatment.
Is At-Home Microneedling the Same Thing?
No.
Professional microneedling allows us to use sterile equipment, controlled needle depths, and treatment settings selected specifically for the patient’s skin and treatment goals.
At-home rollers and microneedling devices cannot replicate the same controlled treatment. Improper technique can also cause unnecessary trauma and potentially increase the risk of irritation, infection, scarring, or post-inflammatory hyperpigmentation.
If your goal is true collagen remodeling—particularly for acne scars—I recommend having microneedling performed professionally.
Is Microneedling Worth It?
For the right patient, microneedling can be an excellent treatment because it improves skin quality by working with the skin’s own repair mechanisms.
I particularly like it for patients who want to address acne scars, uneven texture, fine lines, visible pores, or overall skin rejuvenation without the downtime associated with more aggressive resurfacing treatments.
It is also highly customizable. Treatment depth and technique can be adjusted based on your skin type, the area being treated, and whether our goal is subtle rejuvenation or more significant collagen remodeling.
At Rangel Dermatology, microneedling treatments are customized based on your skin, your concerns, and your goals. As a board-certified dermatologist, I evaluate not only whether microneedling is appropriate for your skin, but also whether another treatment—or combination of treatments—may provide a better result.
