The World Health Organization defines cancer as a group of diseases characterized by the uncontrolled growth of cells. Worldwide, it is estimated that there will be 19.3 million new cases in 2020. Risk factors in Portugal include alcohol, tobacco, excess weight and physical inactivity, highlighting the importance of early diagnosis for a favorable prognosis. Treatments vary, resulting in various adverse effects, particularly on the skin, such as xerosis, hyperpigmentation, hand-foot syndrome, sensitivity to light and itching, requiring care before, during and after treatments. This includes hygiene, moisturizing and sun protection. The careful choice of dermatological products is essential to minimize the adverse effects of treatments. Corrective make-up can help improve patients' quality of life by concealing certain skin alterations. This literature review aims to understand the skin changes inherent to cancer, the drugs that potentiate them and to explore the dermatological care available. To achieve this objective, a bibliographic search was carried out in different databases including Pubmed and google scholar, official entities such as the World Health Organization, the National Health Service and the library of the Coimbra School of Health Technology. Using keywords such as cancer, cosmetics, skin care, dermatology, quality of life, cancer treatments, considering a study period of the last 5 years. Drugs used in clinical practice were discussed, such as Apalutamide, Brigatinib, Capecitabine, Cetuximab, Erlotinib, Gefitinib, Panitumumab, Sorafenib associated with their adverse effects, promoting a better understanding of treatments and their effects, focusing on the needs of cancer patients. The promotion of well-being and adherence to treatment are facilitated by a careful approach to the choice of cosmetic and dermatological products, as discussed. Knowledge of dermatological toxicities is essential for improving the quality of life and therapeutic adherence of cancer patients.
