*3.2.2 Superficial and transdermal application of RF*

Skin of the medial arm is thinner than other areas of the trunk and extremities and is therefore prone to early wrinkling [2]. In addition, the arms and shoulders undergo notable sun exposure resulting in further photoaging that leads to pigmentation changes, rough skin texture, and "crepey" skin appearance. In order to provide a harmonious improvement in appearance of the arms, skin quality must also be carefully assessed and addressed.
