A variety of tumours, both benign and malignant, are found in skin. Benign skin lesions, such as seborrhoeic keratoses and skin tags, are often just a cosmetic nuisance, but some benign skin lesions can be a component of diseases with serious medical consequences (e.g. neurofibromatosis or LEOPARD syndrome). Skin cancer is the most common human cancer and its incidence continues to increase. It most commonly affects older, fair-skinned individuals who have had either acute intermittent exposure to ultraviolet light or chronic ultraviolet light exposure. Organ transplant recipients have a 200-fold increased risk of squamous cell carcinoma. About 2% of patients who develop skin cancer have a genetic predisposition, for example, Gorlin’s syndrome in basal cell carcinoma and familial melanoma syndromes in malignant melanoma. Mutations in the PTCH gene cause Gorlin’s syndrome, and loss of heterozygosity at that locus is also present in most sporadic basal cell carcinoma.

Most activities are done outside the home often make the skin exposed to UV light. Exposure UV light excessively or in a long time can cause the occurrence of skin disorders such as Sunburn, premature aging, lowering skin immunity to skin cancer. In preventing the negative effects of UV light on the skin, various ways can be done such as by using a protector such as clothes, hats, glasses or umbrellas. But this physical protection is not sufficient because of the UV light penetrating power. Sunscreen is a skin care cosmetic that provides physical protection against UV light. Proper use of sunscreen and routine can protect the skin from the negative effects of UV light. This paper describes the effects of UV light on the skin, the function of sunscreen and the right use and compatible types sunscreen in maintaining skin health from the adverse effects of UV light.
