Skincare spotlight: SPF
Now that summer’s in full swing, we’ve got the 411 on the most coveted piece of beauty advice: wearing SPF. We’ll brief you on the basics and winnow down to our top five of the skincare staple.
SPF (Sun Protection Factor) is a relative measure of how long it will take for UVB rays to cause a sunburn. The sunlight is made up of two types of harmful rays: long wave ultraviolet A (UVA) and short wave ultraviolet B (UVB). UVA rays penetrate deep into the dermis, the skin’s thickest layer. While UVB is the chief cause of reddening and sunburn, UVA penetrates deep into the skin and play a major part in skin damage, aging, wrinkles and generating skin cancer. To ensure adequate protection, invest in sunscreen labeled ““Broad Spectrum”, which means it protects against both UVA and UVB rays.
UV Filters are ingredients that absorb or reflect the UV rays that are part of sun light. They fall in two categories: physical and chemical.
Physical sunscreens work by reflecting UV radiation away from the skin – they are like a physical barrier between the skin and the light. Examples include Particles of zinc oxide (ZnO)or titanium dioxide (TiO2).
Chemical sunscreens work by filtering & absorbing UV radiation – their chemical structure converts UV radiation to heat.
The SPF 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 for example, with SPF 30 – it would take you 30 times longer to burn than if you weren’t wearing sunscreen. A higher SPF doesn’t indicate superior sun protection—it indicates that you will remain protected in the sun for a longer amount of time. No sunscreen blocks 100% UVB rays. In fact, anything over an SPF 50 provides only incremental increases in protection. Apply generously or apply every 1hr.5m-2hrs. Seek shade between 10 a.m. and 2 p.m. when the sun is at its peak.
If there is anything that you should take from this article, it’s that you should be wearing some sort of UV blocker or repellent year-round. Long gone are the days when applying sunscreen meant greasiness and white smears. These tried-and-true favourites integrate next-level formulas that encourage luminosity, moisture, and a faux glow.
