Sunscreen or sun block lotion is applied to reduce the damage caused to skin by exposure to sun. It reduces the damage caused to skin by blocking ultraviolet radiation from the sun. Sunscreen lotion contains either an opaque material that reflects light or an organic chemical compound that absorbs ultraviolet rays such as oxybenzone. It is applied on the body parts that are exposed to sun. Sunscreen lotion also protects skin from skin cancer. UV rays cause premature aging and use of sunscreen lotion prevents that problem of skin.

Importance of sunscreen lotion

Sunscreen lotion is used to protest the exposed areas of the body from the harmful effects of the sun rays. Unexposed skin gets affected by sun faster than exposed areas of body as these parts of body have not built up any protective mielanin. Stronger sunscreen lotion such as zinc oxide should be used on the sensitive areas of body. Sunscreen lotion reduces the risk of skin cancer and slows down the ageing process. Fair person need more protection from sun rays, they have less amount of melanin. Fair persons should use a sunscreen with a higher SPF. Use a sunscreen lotion that has an SPF 15 that protects against UVA and UAB rays. Sunscreen lotion with broad spectrum should be used which will protect skin from different kind of sun rays. Sunscreen lotion becomes less effective as it becomes older so do avoid buying it in bulk. Sun block should specifically used on delicate areas such as lips, ears and feet. Sun burns should be protected by zinc oxide cream. It also helps to protect skin against allergies to sunlight.

Types of sunscreen lotion

There are mainly two basic types of sunscreen lotion one will penetrate the outer layer of the skin and absorb ultraviolet rays and other will coat will coat the surface of the skin which will act as physical barrier to ultraviolet rays. Lotion should be applied atleast thirty minutes before going out in sun. It should be used repetitively as our body sweat and whenever one goes outside the house and gets exposed to sun.
