Dr Catherine Borysiewicz, Consultant Dermatologist at the Cadogan Clinic offered her advice to Stylist magazine on keeping skin protected in a heatwave.
With temperatures well above the average British summer, many of us have been struggling with the humidity, changing temperatures throughout the day and not to mention the dreaded commuting.
"Sweaty commutes make skin vulnerable to a build-up of pollutants," says Dr Borysiewicz. "Hot weather calls for lighter formulations with in-built SPF."
Below Dr Borysiewicz shares her advice on choosing the best facial SPF:
When choosing a facial SPF, I look for an SPF 50+ to protect against UVB to prevent burning and UV damage to my skin, but also excellent UVA to protect against pigmentation, ageing and deeper UV damage. I also need a product that will not irritate my sensitive skin, and will sit on my skin and under makeup with a light feel, without clogging and aggravating acne.
It's important to understand your skin-type and look for appropriate products to complement and address concerns. People with sensitive skin should avoid fragranced products. Those with oily skin should look for oil free and lighter lotion products. If you're short for time look for multitasking products such as moisturisers with SPF and UVA protection, but be aware that many facial moisturisers with SPF protection don't have UVA cover (always read the label!)
Understanding SPF and UVA is crucial when choosing skincare products; we know that it is important to protect your skin against both. Never go lower than an SPF 30+, I always recommend an SPF50+ as we rarely apply sufficient sunscreen to the skin. UVA labelling can be more complicated to understand, look for 5* or UVA shield on products. A good sunscreen will be the best anti-ageing product you can buy.
It's important to use facial SPF on a daily basis; don't leave it sitting on the bathroom shelf, use it as part of your daily routine. With that in mind choose an affordable product!
