Skin structure and skin care requirements - From past to future
For a long time in human cultural development, cosmetics and medicine had been considered as one discipline. About 150 years ago, with the onset of industrialisation, the influence of natural science and the identification, isolation and big scale production of chemicals and ingredients, the separation into individual disciplines became apparent.
Without carriers only modest effects - Functions and effects of carriers in cosmetic products
When we talk about carriers in cosmetic products we need to distinguish between particular chemically defined substances and physical carrier bodies. In conclusion, both alternatives have the same effects: combined with active agents they increase the bioavailability. An enhanced bioavailability requires in-depth knowledge on the physiological processes in the skin and strictly contrasts with the idea of "a lot helps a lot!"
Ceramides - lipids with multiple assignments
In combination with other skin components ceramides form a natural barrier in the horny layer. They prevent the dehydration of the skin. There are new products which support the skin-own formation of ceramides.
