Dr Russo Once a Day Sun Protection Invisible Face Gel SPF 50 What makes the Dr Russo Once a Day Sun Protection Invisible Face Gel SPF 50 (£27) so appealing is the fact that it's A) completely clear, meaning it will work on any skin tone and B) the click-up tube comes with a handy brush tip that makes for mess-free application. And while the name says "once a day" and the brand promises 12-hour protection, we still recommend making a habit of reapplying any SPF product you use every two hours, especially if you're outdoors or doing some sort of activity that gets you sweaty.
