Introduction: Overexposure of the skin to the sunlight can cause photoaging and promote the emergence of malignant neoplasms. Sunscreens are used to prevent these alterations and may occasionally cause adverse reactions in children and adults.
Objective: To analyze the frequency and types of adverse reactions caused by sunscreens in adults and children.
Methods: Data analysis of in vivo, non-invasive clinical studies performed at a clinical research institute.
Results: Data from 2,263 adults and 523 children were evaluated, with 13.92% and 4.44%, respectively, presenting some type of reaction.
Conclusions: Sunscreens are effective in preventing photoaging and skin cancer. Cosmetic formulations containing sunscreens may cause adverse reactions with low prevalence.

Introduction: The number of cases of cutaneous carcinoma has been steadily increasing, which calls for the necessity of improving cost effective health strategies aimed at preventing that disease and related complications.
Objective: To perform a cross-sectional study with data collected directly from the participants, through the application of a questionnaire.
Methods: Once the data was collected, the bivariate logistic regression was used to calculate the odds ratio (OR) and the 95% confidence interval (CI) between the independent variables and the risk behavior, which corresponded to the non-daily use of sunscreen and/or other photoprotection method. The sample consisted of 200 students – of which 50% studied mathematical sciences and 50% studied biological sciences.
Results: There was no significant difference between the students' behavior according to the different science field they were studying. Women presented lower risk behavior as compared to men (OR = 0.07; CI 95% = 0.01 - 0.56).
Conclusions: Most university students do not protect themselves adequately when exposed to the sun, with this risk behavior being lower in women. Actions aimed at photo-educating students are important.

Some cosmetics manufacturers have sought to employ ecologically correct manufacturing processes and use ingredients sourced from biodiversity. The present paper introduces a scientific review for professionals who prescribe such products. The bibliographic survey was performed using databases and keyword searches. Cosmetic products can be conventional, natural or organic. Those classified as natural contain ingredients of natural origin, while a great part of the raw materials used in organic ones must be certified as organic. Labels indicate the type of ingredients used in natural and organic formulations, however there is no standardization, meaning that prescribers should have sound conceptual knowledge on the subject.
