Androgenetic alopecia is the most common type of alopecia in both women and men. Although there are clear clinical differences between its male and female patterns, there are physiopathogenic peculiarities in each gender. Changes in the hair cycle, with the shortening of the anagen phase, is responsible for the miniaturization process, transforming the terminal hair in a vellus hair. Treatment objectives are to increase the coverage of the scalp and to delay the progression of hair loss. In a didactic manner, this study goes over androgenetic alopecia’s physiopathogeny, clinical manifestations and therapeutic responses.

Schamberg's disease is a progressive pigmentary dermatosis of chronic course. The present article describes the use of thioglycolic acid peelings in Schamberg's disease, with histological and photographic analyses. A 43-year-old female patient with clinical and histological diagnoses of Schamberg's disease underwent five sessions of 10% thioglycolic acid peeling in gel with an interval of 15 days between each session. The patient had considerable whitening of the lesions, with clinical improvement of 68.7%. Thioglycolic acid solubilizes the haemosiderin, being a treatment option that leads to the whitening of the lesions with good tolerance and few side effects.

One of the signs of perioral aging is the lengthening of the upper lip followed by perioral sagging that leads to the depressed angle of the mouth. Various perioral rejuvenation techniques - such as the use of fillers and ablative techniques - are described, however the inversion of the lip does not usually fully improve with those treatment modalities. The authors describe three patients with depressed angles of the mouth that were surgically corrected through a simple, however little used technique, which produces satisfactory aesthetic results.
