Skin cancer is the main neoplasia in both men and women. Basal cell carcinoma is the primary type of head and neck tumor, comprising 25% of nasal tumors. The treatment of choice is exeresis, which often presents a challenge to the dermatologic surgeon, who must achieve an oncologic cure along with a good aesthetic result. The options for nasal reconstruction are diverse, and some are high in complexity, preventing their common use. The authors present the reconstruction of the nasal dorsum using a flap from de glabellar area, a safe procedure with low surgical complexity and performed in a single step, making it a good option for large lesions of the nasal dorsum.

INTRODUCTION: Nutricosmetics have been used as supplements for hair growth in the treatment of non-cicatricial alopecia. However, there are no studies on using of these products in individuals under 18 years of age.
OBJECTIVE: To assess the efficacy and tolerability of using a nutricosmetic product based on proteoglycans in individuals under 18 years of age with non-cicatricial alopecia.
METHODS: This is a clinical, uncontrolled, and prospective trial. Patients with non-cicatricial alopecia, of both sexes, aged between 6 years and 18 years, received nutricosmetics containing proteoglycan for six months. Three dermatologists independently evaluated standardized pre and post-treatment photos. A hair count was performed in a scalp area of 1 cm², and the patients answered a questionnaire about improvement or worsening.
RESULTS: Eleven patients (100% women) were included. Ten (91%) showed improvement after six months, observed through photographic evaluation, hair count, and self-assessment. No patient presented allergies. Two patients had transient epigastric pain.
CONCLUSIONS: The use of proteoglycans-based nutricosmetics was effective and well-tolerated in children and adolescents with non-cicatricial alopecia.
