There are many peptides being used in skin care effectively but I am
not going to elaborate since all the information is available in the
literature and one only has to look. Of course for those not as well
informed as you one can look at the literature from Sederma,
Centerchem, Presperse, BASF, Laboratories Seriobiologiques and others.
You can read about them in Happi and GCI magazines too. There are also
patents on the use of certain peptide chains in personal care
products. Notably P&G has a patent on using Matrixyl in personal care
products which limits the amount of Matrixyl that Croda/Sederma may
sell to competitors. To get around this Sederma developed Matrixyl
3000 which has no restrictions.
