Needle length is generally 0.2–3.00 mm, with a diameter of > 0.25mm and the materials are variable: stainless steel, titanium, or silver and gold. Stainless steel is the most common type of needle, silver and gold offer antimicrobial properties and carry less of a risk of allergic reactions, and titanium needles usually stay sharper longer (see Figure 1.5).

DermaFrac
DermaFrac treatment is a newer modification of microneedling combining microdermabrasion, microneedling, simultaneous deep tissue serum infusion, and light emitting diode (LED) therapy. DermaFrac treatments target aging and sun damaged skin, acne, enlarged pores, uneven skin tone, wrinkles, fine lines, hyperpigmentation, and superficial scars. It takes approximately 45 minutes to complete a full face treatment when all four modalities are used. This noninvasive, cost‐effective treatment carries the advantage of having no downtime, with individualized selection of serums for infusion (see Figure 1.6) [22].

Clinical considerations
Microneedling is not only used for rejuvenation of the skin. Its use in dermatology and aesthetic medicine has expanded to include the treatment of acne scars, alopecia, dyspigmentation, alopecia, striae, and for many other indications. It can be utilized alone or in combination with other treatment modalities, such as chemical peels, platelet‐rich plasma, radiofrequency, subcision, punch elevation, and lasers. It is often used in conjunction with a topical formulation to enhance its penetration and action.
Microneedling is safely used for enhanced drug delivery to the deeper epidermis and dermis by bypassing the stratum corneum. This strategy has been utilized for burn patients and for rejuvenation, allowing cosmeceuticals to be delivered more deeply. Caution is necessary in deciding which topicals to use during delivery, as inflammation may occur and granulomas have been noted.
Conclusion
Microneedling is a popular treatment in dermatology and aesthetic medicine. Since the development of the first dermaroller over 20 years ago, a variety of new microneedling devices have been introduced. Accordingly, the applications of microneedling in dermatology and aesthetic medicine have expanded indications over the past several years.
Evidence‐based treatment of the skin for a variety of indications have been shown to be safe on all skin types. Microneedling is an effective modality of treatment, especially in patients with Fitzpatrick’s IV and V skin types because it overcomes the side effects of scarring and hyperpigmentation resulting from other procedures in which the epidermis is compromised. It certainly promises to be a valuable technique with its numerous applications and its ever‐expanding modifications.
