Abstract:
:Female hairless mice (strain mutant hr/hr) have been irradiated with increasing doses of UV-B over a period of 4 weeks. They were compared with untreated controls Additional groups of 30 mice were treated with milk base or cream base or milk SPF6 or cream SPF6 or cream SPF8 daily before irradiation. No changes of body weight indicating systemic effects were found. Skin thickness was increased significantly after irradiation. These changes were partially antagonized by cream or milk bases and completely prevented by the corresponding formulations containing sunscreen agents. Under the chosen conditions ultimate load of excised skin samples was increased by irradiation. This effect was not reversed by the bases but by the sunscreen products. Ultimate strain of excised skin samples proved to be the most sensitive indicator. The decrease of ultimate strain after irradiation was partially antagonized by the bases. The sunscreen products had more powerful effect. Due to the effects on skin thickness and ultimate load tensile strength and modulus of elasticity did not show significant changes under the chosen conditions. Likewise, collagen and elastin content per gram wet weight did not show significant changes. Considering the increase of thickness of skin which is prevented by sunscreen products one may conclude also a prevention of formation of additional intercellular material. The results prove the value of sunscreen products. Furthermore, they demonstrate a new method for evaluation of chemicals and sun protection preparations.
