The pH value of the skin and of cosmetic preparations
Many of the processes in physics and chemistry are non-linear processes. The following rule of thumb for the shelf life of cosmetic preparations can here be quoted as an example: The shelf life of a cosmetic cream (emulsion) halves when the temperature is raised by 10 °C while it doubles when the temperature is dropped by 10 °C. Similar applies to the pH value where an increase or a drop has a considerable impact on biochemical reactions and the activity of epidermal enzymes. How does the pH work?
CO2 – more than just a greenhouse gas
There is not a single day without the horror stories on climate change and its consequences, be it in newspapers, broadcasts or TV. One of the main polluters is carbon dioxide or abbreviated CO2. Many of its useful properties however get caught up in the maelstrom of the negative communication.  The following paper is intended to partially rehabilitate the agent, among others also in the areas cosmetics and healthiness.
The water balance in our skin: moisturizers & Co.

Acids and bases from A to Z
Acids somehow have a spectacular image in skin care. They either have caustic effects in the true sense of the word or they are the magic cure for a beautiful skin per se. Bases, as their counterparts, only live a wallflower existence as neutralizers. Details and backgrounds are covered in the following article.
The ABC of fatty acids
We come into contact with fatty acids day in, day out as they are elements of our daily nutrition and skin care. Already the syllable „fat" reminds us of calories and even more disagreeable is the idea of something like "acids". Fatty acids have more influence on our health than we generally assume, though. Their metabolic products control a multitude of functions in our body and in the skin.
Omnipresent and multifunctional - amino acids in skin care
Amino acids are indispensable from the vegetable and animal kingdom including men through to microorganisms like bacteria, fungi and viruses. There is no life on earth without these basic elements. Why and which specific amino acids are vital for the human skin is described in the following.
Vegetable oils
Vegetable oils are the oldest known skin care products. Yet they are important as ever. Find out more about the manifold and interesting features of this substance group in the following.
Peptides - more than transmitters and hormones
Peptides play a major role in the development of anti aging cosmetics. They occur naturally and are quite often found as messenger proteins and hormones. Also their degradation products, i.e. the amino acids are key players in the field of cosmetic skin care.
Essential fatty acids - cosmetic from inside and outside
Our body depends on numerous substances which have to be replenished with our daily nutrition. Certain fatty acids are among these essential substances. Deficiencies have a detrimental effect for the human organism and skin.
