Microneedling
Collagen induction therapy using controlled micro-injuries for skin rejuvenation
Microneedling, also known as collagen induction therapy (CIT) or percutaneous collagen induction (PCI), is a minimally invasive skin rejuvenation procedure that uses fine, sterile needles to create thousands of controlled micro-punctures in the skin's surface. These microscopic channels trigger the body's natural wound healing response, stimulating the production of new collagen and elastin to improve skin texture, firmness, and overall appearance.
The treatment is effective for a wide range of skin concerns including fine lines and wrinkles, acne scars, enlarged pores, stretch marks, uneven skin tone, and overall skin dullness. Microneedling can be performed on the face, neck, decolletage, and body, making it one of the most versatile skin rejuvenation treatments available.
Unlike ablative procedures that remove skin tissue, microneedling preserves the epidermis, resulting in faster healing and a significantly lower risk of complications such as hyperpigmentation [1]. This makes microneedling suitable for a broader range of skin types and tones compared to laser resurfacing or deep chemical peels.

01 / The brief
What to know first
Microneedling has evolved from rudimentary dermarolling techniques into a sophisticated clinical procedure using automated pen-like devices with adjustable needle depths and speeds. The concept was first described in the mid-1990s by plastic surgeon Dr. Desmond Fernandes, who demonstrated that controlled needle punctures could stimulate collagen production and improve scarring. Since then, the technology and technique have been refined significantly.
Professional microneedling devices, such as the SkinPen (the first FDA-cleared microneedling device for acne scars) [1], Dermapen, and similar automated devices, use a cluster of fine needles (typically 12-36) that oscillate rapidly to create precise, uniform micro-channels in the skin. Needle depth is adjustable from 0.25mm to 2.5mm or more, allowing the practitioner to customize treatment depth based on the target area and condition [1]. Shallower depths (0.25-0.5mm) are used for product penetration and mild texture improvement, while deeper settings (1.5-2.5mm) target acne scars, stretch marks, and more significant collagen induction.
The wound healing cascade initiated by microneedling occurs in three phases. The inflammatory phase (days one to three) involves platelet activation and release of growth factors including platelet-derived growth factor (PDGF) and transforming growth factor (TGF). The proliferative phase (days three to five) sees fibroblasts migrating to the treatment area and beginning to deposit new collagen type III. The remodeling phase (weeks to months) involves the gradual replacement of collagen type III with stronger collagen type I and the reorganization of the extracellular matrix, resulting in firmer, smoother skin.
Microneedling with platelet-rich plasma (PRP), sometimes called the "vampire facial," combines microneedling with topical application of the patient's own concentrated platelets. PRP contains a high concentration of growth factors that may enhance the collagen stimulation response when applied to the micro-channels created during treatment. Clinical studies have shown improved outcomes for acne scarring and skin rejuvenation when PRP is added to microneedling compared to microneedling alone [1].
Radiofrequency microneedling (RF microneedling) represents the latest evolution of the technology. Devices such as Morpheus8, Genius, and Vivace deliver radiofrequency energy through insulated needles directly into the dermis, combining the collagen-stimulating effects of both mechanical needling and thermal energy. RF microneedling produces more significant skin tightening and is particularly effective for acne scars, enlarged pores, and mild skin laxity.
02 / Approaches
Techniques and options
Standard microneedling begins with thorough cleansing of the treatment area followed by application of a topical numbing cream (typically lidocaine 4-5%) for 20 to 30 minutes. Once the area is adequately numbed, the skin is cleansed again and a thin layer of hyaluronic acid serum is applied to provide glide for the microneedling device.
The practitioner moves the device across the skin in a systematic pattern, making multiple passes in vertical, horizontal, and diagonal directions to ensure uniform coverage. Treatment speed is controlled, with the device moving smoothly across the surface without excessive pressure. Needle depth is adjusted throughout the procedure based on skin thickness in each area -- deeper on the cheeks and forehead, shallower around the eyes, nose, and lips. The clinical endpoint is uniform pinpoint bleeding or petechiae, indicating adequate penetration to the papillary dermis.
For acne scar treatment, the provider may use a stamping technique with deeper needle settings (2.0-2.5mm) directly on individual scars, particularly for ice pick and boxcar varieties. This targeted approach concentrates the collagen induction response precisely where it is most needed. Multiple treatment sessions spaced four to six weeks apart are typically required for meaningful scar improvement [1].
When combining microneedling with PRP, blood is drawn from the patient before the procedure and processed in a centrifuge to isolate the platelet-rich fraction. The PRP is then applied topically to the skin during and immediately after microneedling, allowing the growth factors to penetrate through the micro-channels. Some providers also inject PRP directly into deeper scars before microneedling for enhanced effect.
03 / Candidacy
Who may be a candidate
Often considered
Ideal candidates for microneedling are individuals seeking improvement in skin texture, fine lines, mild to moderate acne scars, enlarged pores, uneven skin tone, or overall skin dullness. The treatment is suitable for all skin types and colors, making it an excellent option for patients who may not be candidates for laser resurfacing or deep chemical peels.
Good candidates are in overall good health, do not have active skin infections or inflammatory conditions, and are not currently using isotretinoin. Patients who prefer a gradual, natural improvement approach with minimal downtime are well-suited for microneedling. Those seeking to enhance the results of their existing skincare routine or complement other cosmetic treatments also benefit from this procedure.
Reasons to pause
Microneedling is not suitable for individuals with active acne, eczema, psoriasis, rosacea, or any skin infection in the treatment area. Open wounds, sunburned skin, or active cold sores are contraindications. Patients currently taking isotretinoin or who have taken it within the past three to six months should avoid treatment due to impaired wound healing.
Those with bleeding disorders, uncontrolled diabetes, or who are on anticoagulant therapy may face increased risks. Patients with active skin cancer or precancerous lesions in the treatment area should not undergo microneedling. Pregnant women should postpone treatment. Patients with a history of keloid scarring should proceed with caution and discuss risks thoroughly with their provider, as microneedling could potentially trigger keloid formation in susceptible individuals.
04 / Tradeoffs
Potential benefits and risks
Potential benefits
Microneedling offers a natural approach to skin rejuvenation by harnessing the body's own healing mechanisms rather than relying on external substances or thermal energy. The treatment stimulates genuine collagen and elastin production, creating lasting structural improvements in the skin.
The procedure is suitable for all skin types and tones, including Fitzpatrick types IV-VI, which face higher risks with many laser and chemical peel treatments [1]. This inclusivity makes microneedling one of the most broadly applicable skin rejuvenation options available.
Microneedling is versatile enough to treat the face, neck, chest, hands, and body areas including stretch marks on the abdomen and thighs. Recovery is rapid, with most patients returning to normal activities within 24 to 48 hours. The treatment can be combined with PRP, growth factors, or radiofrequency energy for enhanced results, and it complements other treatments such as Botox, fillers, and topical skincare regimens.
The cost per treatment is among the most affordable of professional skin rejuvenation procedures, providing excellent value relative to results achieved.
Risks to discuss
Microneedling is considered one of the safest skin rejuvenation procedures, with a low complication rate when performed by a qualified provider using proper technique and sterile equipment. Common side effects include temporary redness resembling a mild to moderate sunburn, mild swelling, skin tightness, and minor pinpoint bleeding during treatment. These effects typically resolve within 24 to 72 hours [1].
Less common risks include temporary post-inflammatory hyperpigmentation, which is more likely with aggressive treatment settings or inadequate sun protection during healing. Unlike ablative laser treatments, microneedling preserves the epidermis and carries a substantially lower risk of pigmentation changes, making it safer for darker skin tones [1].
Infection is a rare risk that is minimized through proper sterile technique and post-treatment care. Herpes simplex reactivation can occur in susceptible patients if prophylactic antiviral medication is not used. Allergic reactions to topical serums applied during treatment are possible. Granuloma formation has been reported rarely, typically associated with the use of inappropriate topical products during microneedling that are driven deeper into the skin through the micro-channels.
05 / Planning
Preparation and recovery
Before the procedure
Discontinue retinoids, exfoliating acids, and other active skincare ingredients two to three days before treatment. Avoid sun exposure and tanning for at least one week prior to the appointment, as sunburned or tanned skin increases the risk of complications.
Arrive with a clean face, free of makeup and skincare products. If you are prone to cold sores and the treatment area includes the perioral region, your provider may prescribe antiviral medication to take before and after treatment.
Avoid blood-thinning medications and supplements (aspirin, ibuprofen, fish oil, vitamin E) for three to five days before the procedure to minimize bruising and bleeding. Inform your provider of all medications, skin conditions, and previous treatments during your consultation.
Aftercare
Immediately after microneedling, the skin will appear red and may feel warm, similar to a mild sunburn. Apply only the products recommended by your provider for the first 24 hours -- typically a bland hydrating serum or hyaluronic acid. Avoid active ingredients including retinoids, vitamin C, alpha-hydroxy acids, and fragranced products for at least 48 to 72 hours after treatment.
Do not apply makeup for at least 12 to 24 hours post-treatment, as the micro-channels remain open and can absorb unwanted chemicals or harbor bacteria. Use a gentle, non-foaming cleanser and a simple moisturizer for the first two to three days. Apply broad-spectrum SPF 30 or higher sunscreen daily, as the fresh skin is particularly sensitive to UV damage.
Avoid swimming, saunas, hot tubs, and strenuous exercise for 24 to 48 hours to prevent irritation and infection risk. Do not pick or scratch any flaking skin that may occur as the skin heals. Resume normal skincare routine after three to five days or as directed by your provider.

Expected results
Patients typically notice initial improvement in skin texture, brightness, and pore appearance within one to two weeks after a microneedling treatment, with progressive improvement over the following weeks as collagen remodeling takes effect. The most significant results are seen after a series of three to six treatments spaced four to six weeks apart, as each session builds upon the collagen stimulation of the previous one.
For acne scarring, clinical studies have demonstrated 50-70% improvement in scar appearance after a series of three to four treatments [1]. Results for fine lines and wrinkles are generally 20-40% improvement, with continued enhancement over three to six months as new collagen matures [1]. Improvements in skin tone and texture are often noticeable after the first treatment.
Results are long-lasting because the new collagen and elastin produced through microneedling become a permanent part of the skin's structure. However, the skin continues to age naturally, so maintenance treatments every six to twelve months help sustain optimal results. Combining microneedling with proper skincare (retinoids, antioxidants, sunscreen) maximizes and prolongs the benefits of treatment.
06 / Common questions
Frequently asked
How many microneedling sessions do I need for visible results?
Most patients see noticeable improvement after a single session, with optimal results achieved through a series of three to six treatments spaced four to six weeks apart. The number of sessions depends on the specific concern being treated. Mild texture and tone improvement may require three sessions, while moderate acne scarring typically benefits from four to six sessions. Maintenance treatments every six to twelve months help sustain results. Your provider will create a customized treatment plan based on your individual needs and goals.
Is microneedling safe for dark skin tones?
Microneedling is one of the safest skin rejuvenation procedures for all skin tones, including darker complexions (Fitzpatrick types IV-VI). Unlike ablative lasers and deep chemical peels, microneedling preserves the epidermis and carries a significantly lower risk of post-inflammatory hyperpigmentation. However, appropriate needle depth, proper technique, and diligent post-treatment sun protection are important for minimizing risks in darker skin. Always choose a provider experienced in treating diverse skin types.
What is the difference between microneedling and RF microneedling?
Standard microneedling creates mechanical micro-injuries that stimulate collagen production through the wound healing response alone. Radiofrequency (RF) microneedling adds thermal energy delivered through insulated needles into the dermis, combining mechanical and thermal collagen stimulation for enhanced skin tightening, scar improvement, and pore reduction. RF microneedling produces more significant results, particularly for skin laxity, but costs more per session. Your provider can recommend which option is best suited to your specific concerns.
