It is characterized by a benign dermatosis, with papular and pustular follicular lesions that first appear on the torso and occasionally spread throughout the body.

Transepidermal retinoic acid delivery using ablative fractional radiofrequency associated with acoustic pressure ultrasound for stretch marks treatment.

Background: Striae distensae (SD) treatment still remains a therapeutic challenge to dermatologists. Ablative fractional laser and radiofrequency (RF) enhance skin-drug permeability for SD treatment.

Objective: To clinically evaluate the efficacy and safety as well as patient's satisfaction in relation to a method using ablative fractional RF associated with retinoic acid 0.

Fox-Fordyce disease: response to adapalene 0.1%.

The Fox-Fordyce disease is a rare inflammatory dermatosis that affects mainly young women and is characterized by multiple follicular papules, skin color or brownish, very itchy, localized in areas rich in apocrine glands.
