Aurinkovoidetta

Aurinkovoidetta, known in English as sunscreen or sunblock, is a lotion, spray, gel, foam, or stick applied to the skin to protect it from the harmful effects of ultraviolet (UV) radiation from the sun. It works by absorbing or reflecting UV rays before they can damage skin cells. The primary active ingredients in aurinkovoidetta are either chemical filters, which absorb UV radiation, or mineral filters (physical blockers) like zinc oxide and titanium dioxide, which create a barrier on the skin's surface.

The effectiveness of aurinkovoidetta is measured by its Sun Protection Factor (SPF), which indicates how well the product protects against UVB rays, the primary cause of sunburn. A higher SPF number offers greater protection. It is also important to consider protection against UVA rays, which contribute to premature aging and skin cancer. Products labeled "broad-spectrum" offer protection against both UVA and UVB radiation.

Aurinkovoidetta should be applied generously to all exposed skin at least 15 minutes before sun exposure. Reapplication is recommended every two hours, and more frequently after swimming or sweating. Regular use of aurinkovoidetta is a key strategy in preventing sunburn, reducing the risk of skin cancer, and minimizing signs of premature skin aging such as wrinkles and sunspots. Different formulations are available to suit various skin types and preferences.
