Which SPF I Should Use?
Sunscreen with UV SPF protection is an essential skincare product in your skincare regime. However, do you know what SPF is and why there are sunblocks and creams with different range of SPF? Many of you might not know about SPF and its significance for the protection of your skin against the harmful UV sunrays. To guide you about SPF and which you should use, here is a brief guide.
What Does SPF Stand For?
SPF means ‘Sun Protection Factor.’ It actually measures the potency of the protection your sunscreen cream or lotion provides against the damaging UVB sunrays. For instance, if your skin is likely to get burned after staying for 10 minutes in the sunlight, then the application of SPF 15 before going into the sun keeps your skin protected from sunburn for 150 minutes approximately. However, it is not a precise measure.
Spending more time in the sunlight increases your chances of getting skin burn, sun damage, premature aging, and even skin cancer. It is recommended for lighter skin tones to use a broad-spectrum sunscreen with SPF 30 or higher and UVA/UVB protection to ensure maximum defense against the dangerous sunrays. UVB rays are the cause of physical skin burns while UVA rays penetrate deeper in the skin, causing premature aging.
Which SPF Is Suitable For Darker Skin Tones?
Darker skin tones can use SPF 15 or lower as these skin tones have plenty of melanin, which provides sun protection. However, it should also be broad spectrum that provides both UVA and UVB protection.
Which SPF Is Suitable For Lighter Skin Types?
People with lighter skin tones should use a sunscreen with SPF 30 or higher. If you have light skin tone or complexion and you face plenty of direct sun exposure daily, then you should consider using SPF 30 or higher in your routine.
Ingredients to Look For In Broad Spectrum SPF Sunscreen
A sunscreen that provides broad-spectrum UVA and UVB protection generally has the following components; benzophenones (oxybenzone), sulisobenzone, cinnamates (octyl methyl cinnamate and cinoxate), titanium dioxide, salicylates, ecamsule (Mexoryl SX), avobenzone (Parsol 1789) and zinc oxide.
So when you are searching for SPF sunscreen, look for these active ingredients in the list and always wear sunscreen when you are outside!
