A higher SPF offers better protection from the sun's damaging rays. Generally, SPF 15 is seen as low protection, 15-30 is medium, like our Rénergie SPF 20 Cream and 30+ is high. Your choice of protection will depend on the intensity of the sunlight and your skin type. Our Teint Idole Ultra Wear, Absolue Premium and Hydra Zen ranges all have options which include SPF.
