Dermastir sun protection SPF50+ in an airless thermal luxury packaging was launched by ALTA CARE Laboratoires - Paris. The UV filters and the ingredients in Dermastir are protected from oxygen by the airless packaging and so the ingredients do not risk oxidation. Dermastir sun protection SPF50+ packaging consists of 3 jars nested into 1 creating a "thermos effect" because of the insulation between one jar and the other. This thermally protects the ingredients from heat. The inner jar is metallic coated to reflect infrared rays, thus apart from protecting the ingredients from the heat also protects the ingredients from light. This is very important especially since many sun protections are not photostable and the cream ends up turning yellow after being opened often. The pump has an actuator in the middle that when pressed delivers the correct amount of ingredient without the need of putting one's finger in the cream that increases the risk of microbiological contamination.
