We all know getting sunburned isn't good for you, but for some of us, our suncare knowledge stops there. Here at Sonrei we believe not only in premium sunscreen, but also premium education about that sphere of hot plasma we call the sun.
The SPF or “Sun Protection Factor" number tells you how long the sun’s UV radiation would take to redden your skin when using the product exactly as directed versus the amount of time without any sunscreen. So ideally, with SPF 30 it would take you 30 times longer to burn than if you weren’t wearing sunscreen.
Classic and mineral sunscreens are differentiated by their active sunscreen ingredients. The active ingredients in classic or organic sunscreen (also referred to as chemical or traditional sunscreen) are designed to absorb and dissipate UVA/UVB rays. The active ingredients in mineral or inorganic sunscreen (also referred to as physical sunscreen) reflect UVA/UVB rays.
There are two types of ultraviolet (UV) light that can harm your skin – UVA and UVB. A Broad Spectrum sunscreen protects you from both. UVB rays are primarily responsible for causing sunburn while UVA rays are associated with skin aging.
All adults should make it a habit to check their skin and moles every 3 months. If you're at risk for developing skin cancer, have a board-certified dermatologist examine your moles at least once a year.
Melanomas can develop in between visits to your skin cancer doctor, therefore you should know how to check your own skin and moles.
If you find any new or suspicious spots on your skin or any spots that are changing, itching, or bleeding, make an appointment to see a board-certified dermatologist.
