SPF: All Day, Every Day

SPF: All Day, Every Day​

Most people are surprised when I tell them they need to wear their SPF even indoors. Lately, during consults with prospective skincare customers, I hear something like: "Well with COVID, I'm not going out outside as much so of course I haven't needed my SPF."

The thing is, UVA light can penetrate glass. UVA is the "aging" light, while UVB is the "burning" light. According to the Skin Cancer Foundation, more than 50 percent of UVA light can get through, so if you're within several feet of the window, the rays can reach you. This applies to indoors and to driving, as the rays can penetrate car glass too.
