P4O infuse our SPF30 sunscreen with carrot seed oil and carotene. Most people know carrots are good for the eyes, but carrot seed oil (Daucus carota sativa) is also beneficial for the skin. It is a strong antioxidant that is high in vitamins A, C, E and K, making it ideal for mature or sun-damaged skin. P4O add it to their sunscreen as it is a great emollient and highly nourishing.
