Sunscreen is one of the least expensive types of dermatology products but it plays a very important role in the health of your skin. Sunscreens work by reflecting, scattering or absorbing UV rays that can damage the skin. There are many different types of sunscreens available which contain a wide variety of ingredients. Choosing the right sunscreen will depend upon an individual’s lifestyle and the types of activities that they will participate in outdoors. No matter which type is chosen it is essential that it provides protection from both UVA and UVB rays.
