  • the majority of UV-A radiation penetrates the living epidermis, while around 70% of UV-B rays are retained by the horny layer.
  • UV-A radiation has only a negligible biological effect and that UV-B rays are accordingly responsible for most of the light damage to human skin.
  • UV-B radiation is far more dangerous than UV-B radiation in terms of triggering photodynamic, especially phototoxic reactions and chronic changes in the skin.
  • the damaging influence of UV-B radiation can also be intensified by UV-A radiation.
  • the sunburn or the light erythema are the acute manifestations of the effect of light.
  • particularly strongly exposed areas of the skin face, neck, hands
  • the most noticeable chronic light damage to the skin is actinic or senile elastosis. Macroscopically, it manifests itself in thickening and coarsening of the skin, wrinkling, loss of elasticity, the appearance of yellowish shimmering deposits and irregular pigment accumulations.
  • the epidermis becomes thin in places and shows warty growths, the dermis loses its elasticity and tension, the water retention capacity is reduced.
  • Late complications include malignant melanoma and, in the last stage, actinic keratosis.
  • the benefit of a sunscreen preparation is to extend the amount of time that a consumer can stay in the sun without causing light damage.
  • the filter effect should be adapted in particular for the UV-B range to the individual sensitivity of the consumer and the intensity of solar radiation.
  • the weakening of the intensity of the incident light and thus the effectiveness of a sun protection formulation depend, among other things, on the layer thickness of the applied filter substance. With increasing layer thickness, the effectiveness of a sunscreen also increases. Particularly in the case of low-viscosity preparations such as oils or alcoholic solutions, it is therefore necessary to also increase the viscosity of the formulation and thus the achievable layer thickness on the skin from a certain limit concentration of filter substance. In addition, it is only possible to a limited extent to increase the sun protection factor by increasing the concentration of the UV filter substance.

H. whether the layer thickness was chosen sufficiently.
  • Another disadvantage is that the user cannot keep track of how the layer thickness of the sunscreen changes, for example due to contact with water or mechanical stresses such as drying, etc., and accordingly when a new creaming has become necessary.
  • a high level of protection of the preparations is of particular importance, especially for children's and baby products, since children are particularly susceptible to sunburn due to the low light swell (thickening of the horny layer) and the reduced level of self-protection and also often play for hours on or in the water.
