Mechanical skin needling creating microchannels. Studied for collagen induction, acne scars, and skin rejuvenation.
◆Moderate evidence
The Idea
Microneedling is an in-clinic procedure that uses mechanical skin needling to create microchannels in the skin, inducing collagen production and promoting skin rejuvenation. This device is studied for its potential to improve the appearance of acne scars and fine lines. The proposed mechanism of action involves the stimulation of collagen synthesis and tissue repair.
What the Evidence Shows
Research suggests that microneedling can improve skin texture and reduce the appearance of fine lines and acne scars. Studies indicate that collagen production is increased following microneedling treatments, with some studies showing significant improvements in skin elasticity and firmness. However, evidence is limited by the small sample sizes and variability in treatment protocols used across studies. More high-quality, randomized controlled trials are needed to fully understand the efficacy of microneedling for skin rejuvenation.
Verdict
The current state of clinical use suggests that microneedling is a promising treatment option for skin rejuvenation, but its effectiveness can vary depending on individual factors and treatment protocols. While some studies indicate positive outcomes, more research is needed to fully establish the benefits and limitations of this procedure.

3D-Printed Microneedles May Help Deliver Antioxidants Deep into the Skin
Researchers developed a new way to deliver antioxidants deep into the skin using 3D-printed microneedles. They tested this method with a specific antioxidant called resveratrol, which is found in some foods. The microneedles were able to deliver the antioxidant into the skin, where it could potentially provide benefits. However, more research is needed to confirm these findings.
Why it matters: This research may help improve our understanding of how to deliver antioxidants to the skin, which could potentially lead to new skincare treatments.
This study was conducted in human volunteers, but the sample size is not specified. The study only tested the delivery of a single antioxidant, resveratrol, and more research is needed to confirm these findings.

Cooling Device May Help Enhance Skin Penetration for Skincare Treatments
Researchers studied a cooling device called TargetCool to see if it could help skincare products penetrate deeper into the skin. They found that it may enhance skin penetration, especially when used with microneedling devices. However, more research is needed to confirm these findings.
Why it matters: This study may help improve our understanding of how to deliver skincare treatments more effectively.
This study was conducted in a lab using human skin samples, and the results may not translate to real-world use. The study only looked at one specific skincare ingredient and did not examine its effects on skin health or appearance.

Microneedling, Microdermabrasion, and Microvibration for Skin Renewal
Researchers studied the effects of microneedling, microdermabrasion, and microvibration on skin renewal. They found that these treatments may influence skin texture, scarring, and epidermal renewal, but the underlying mechanisms are not yet fully understood. More research is needed to refine personalized approaches.
Why it matters: Understanding how these treatments work may help guide treatment selection and optimization for skin rejuvenation.
The review synthesizes existing clinical, histological, and molecular data, but more standardized studies and deeper proteomic analyses are needed to refine personalized approaches.

Combining microneedling with oral doxycycline may help treat rosacea symptoms
Researchers studied whether adding microneedling to oral doxycycline improves treatment outcomes for people with rosacea. They found that combining these two treatments may help reduce facial erythema, flushing, and burning sensations, and may also reduce the risk of rosacea relapse. However, more research is needed to confirm these findings.
Why it matters: This study may help skincare professionals better understand how to treat rosacea symptoms and improve patient outcomes.
This study was a small retrospective comparative cohort study with a sample size of 160 patients, and more research is needed to confirm these findings.

Radiofrequency Microneedling May Help Improve Skin Texture and Reduce Signs of Aging
Researchers studied the effectiveness of radiofrequency microneedling (RFMN) for various skin conditions, including acne scars, skin laxity, and rosacea. They found that RFMN may improve skin texture and reduce signs of aging, but the evidence is not consistent across all conditions. More research is needed to fully understand its benefits and limitations.
Why it matters: This study may help skincare professionals and individuals better understand the potential benefits and risks of RFMN for various skin concerns.
The study included a diverse range of studies, but the quality of the evidence varied, and the reporting of technical parameters was inconsistent. Additionally, the study did not compare RFMN to other treatments directly.
