Microneedling therapy is an increasingly popular treatment of several dermatologic conditions. Platelet-rich plasma (PRP) may serve as a valuable adjunct to improve the regenerative effects of treatment. We review the evidence comparing the results of microneedling therapy with and without PRP. Based on the current preliminary literature, PRP appears to augment the cosmetic outcomes of micronee...

Microneedling is a minimally invasive procedure that is becoming widely utilized in dermatology. Microneedles (MNs) are fine, needle-like structures that penetrate the skin. MNs can be used for percutaneous collagen induction (PCI) therapy and to augment transdermal drug delivery. This review is a primer on microneedling for dermatologists. It provides an overview of the history, instruments, p...

BACKGROUND AND OBJECTIVES Various physical methods, such as microneedling, laser ablation, sonophoresis, and sandpaper, have been widely studied to enhance the transdermal delivery of tissue optical clearing (TOC) agents. A previous study demonstrated that the microneedling method could effectively enhance the permeability of a TOC agent through the skin barrier. STUDY DESIGN/MATERIALS AND ME...

BACKGROUND Melasma is a common chronic and relapsing acquired dyschromia. Skin microneedling was reported resulting sustained long-term improvement of recalcitrant melasma, however, the exact mechanism that promotes this skin lightening is not known. This study aimed to investigate clinical and histologic alterations promoted by skin microneedling in facial melasma. METHODS Open pilot trial i...

Background: Microneedling has been shown to be a clinically effective and safe treatment for comedonal acne vulgaris. The aim of the present study was to compare the clinical effectof microneedling and the most commonly used topical drug, tretinoin, in the treatment of comedonal acne.Methods: Patients with comedonal acne (n = 82) were randomized to receive topical tretinoin (n = 41)...

CONTEXT There are very few studies evaluating efficacy of platelet-rich plasma (PRP) in hair restoration and its combination with microneedling. As far as ascertained, there is no study to evaluate efficacy of microneedling with PRP plus topical minoxidil (5%) versus topical minoxidil (5%) alone in androgenetic alopecia (AGA). AIMS This study aims (1) to compare the efficacy of (a) topical mi...

BACKGROUND Various treatment modalities including non-invasive methods such as chemical peels, topical retinoids, microdermabrasion, minimally invasive techniques such as microneedling, fractional lasers, microneedling radiofrequency devices and invasive procedures such as acne scar surgeries and ablative lasers are used for acne scars, each with its own unique advantages and disadvantages. Thi...

BACKGROUND Stretch marks can have a negative psychological impact on some individuals. Methods are available for treating stretch marks, but high-quality evidence supporting their use is limited. We treat stretch marks using injections of diluted calcium hydroxylapatite (CaHA, Radiesse) filler combined with microneedling and topical ascorbic acid. This retrospective study evaluated the effectiv...

BACKGROUND The use of growth factors in skin rejuvenation is emerging as a novel anti-aging treatment. While the role of growth factors in wound healing is well established, their use in skin rejuvenation has only recently been to be studied and no controlled trials have been performed. OBJECTIVE We evaluated the anti-aging effects of secretory factors of endothelial precursor cells different...

Background: Microneedling is recently used to treat skin scars mostly atrophic scars; however, there are limited data about its effectiveness on hypertrophic burn scars. Carbon dioxide (CO2) laser is an effective method for the treatment of burn scars. Here, we aim to compare the efficacy of microneedling to CO2 laser in the treatment of hypertrophic burn scars in a randomized clinical trial. M...
