Did you know that your sunscreen might actually not be as effective as it claims? This is irrespective of the very high SPF and PA levels it offers. Photostability is a new term that will soon be used to refer to the effectiveness of a sunblock or a sunscreen. Photostability is referred to how stable a sunscreen is even after exposure to UV rays. If the effectiveness keeps decreasing, then it is an unstable product. Photostable Sunscreen Gel is a product that is designed to stay intact with UV exposure, protecting the skin all day long.
