  • the present invention relates to cosmetic preparations containing one or more ⁇ -hydroxycarboxylic acids and / or one or more ⁇ -hydroxycarboxylic acids and / or one or more polyhydroxy acids, one or more distearates and starch.
  • the skin is exposed to stress from numerous external and internal factors. Extrinsic factors include ultraviolet radiation (eg, sunshine), pollution, wind, heat, low humidity, aggressive surfactants, abrasives, and the like.
  • Intrinsic factors include chronological age and other biochemical changes within the skin. Whether externally or internally, these factors result in visible signs of skin aging and environmental damage, such as the appearance of wrinkles and other forms of roughness (including enlarged pores, scales). and other histological changes associated with skin aging or damage. Skin folds remind many people of the disappearance of youth.
  • the aim of skin care is also to compensate for the daily loss of fat and water loss of the skin. This is especially important when the natural regeneration capacity is insufficient.
  • skin care products to protect against environmental influences, especially from the sun and wind, and delay the aging of the skin.
  • Exogenous factors such as UV light and chemical noxae can be cumulatively effective and e.g. accelerate or supplement endogenous aging processes.
