When and how should I use SPF products?
Dr Murad recommends the use of SPF (sun protection factor) daily even if you work inside and are only exposed to ultraviolet radiation for brief periods throughout the day. Colder weather doesn’t always mean less sun so make sure that you protect yourself from UVA and UVB rays year round. Fitting an adequate SPF into your skincare regime is a must, no matter the temperature or weather conditions. Staying sun safe is as simple as using the right products. SPF is important because not only can sun exposure result in developing skin cancer, it also ages your skin causing lines, wrinkles, loss of firmness, uneven skin tone and rough texture. SPF stands for sun protection factor, which is a measure of the amount of time you can spend in the sun before getting a sunburn.
