Sunscreen is a cream or lotion whose purpose is to protect against the harmful effects of ultraviolet radiation from the sun. This sun lotion is mainly applied on the beaches in summer or on the ski slopes, and is manufactured by cosmetic or pharmaceutical laboratories.
A sun lotion is composed of ultraviolet filters in a base which can be an oil or more frequently an emulsion. An aqueous emulsion allows you to apply a greater thickness of product to the skin and is not greasy to the touch .
The sun lotion generally contains other ingredients: preservatives, agents to stabilize the emulsion, anti-free radicals (vitamin E or vitamin C for example), thickeners, moisturizing agents. The formulation takes into account the fact that the product must adhere to the skin, and resist water .
There are two types of ultraviolet filters to be able to take full advantage of the sun :
Most sunscreen products contain chemical filters or mineral filters or both.
Most people only apply sunscreen when doing outdoor summer activities. We recommend the application of a solar product 20 minutes before exposure to the sun for children and adults , and to renew the application. However, some experts suggest using it daily to prevent cumulative damage. With a view to preventing wrinkles and anti-aging action, manufacturers market day lotions containing UV filters, for daily use .
Sand , friction from towels and water remove some of the lotion on the skin and therefore reduce sun protection. In addition, some sunscreens are degraded by ultraviolet rays. This is why we recommend regularly reapplying the lotion every 2 hours and after each swim, even if it is water resistant.
