The inhomogeneity of the 72k eye and face cream is due to the unrefined, organic shea butter it contains. We have also seen this phenomenon in the past, here is the explanation: Shea butter has a melting range of 24°C-38°C with an average melting point of 28°C. If the face cream is stored in this temperature range, it can happen that the shea butter melts and then crystallizes again when the surrounding temperature drops below 28°C or 24°C. This is a phenomenon known as recrystallization. These crystalline areas can then be seen as inhomogeneity (white dots) in the product. However, this has absolutely no effect on the quality of the product. When the cream is rubbed in, the crystalline areas of shea butter immediately melt again and the cream spreads easily. Nevertheless, we are investigating this issue to avoid this happening in future. The question naturally arises as to why we still use this ingredient Butyrospermum parkii butter. Native shea butter (also known as shea butter or beurre de karité) has a high content of cosmetically valuable ingredients, including phytosterols, wax esters, tocopherols, antioxidant catechins and gallic acid as well as skin-friendly fatty acids. Their high proportion of unsaponifiable is particularly noteworthy, especially the phytosterols mentioned (including campesterol, stigmasterol, ?-sitosterol and ?-spinasterol), triterpenes (cinnamic acid esters, ?- and ?-amyrin, parkeol, butyrospermol and lupeol) and tocopherols. Their proportion is between 6 and 12 %, sometimes 16 % is mentioned in the literature. Thanks to its broad spectrum of ingredients, shea butter regulates the skin's moisture content and has a moisturizing, soothing and smoothing effect. Its content of unsaponifiable strengthens the lipid barrier of the horny layer and predestines shea butter for the treatment of dry, neurodermitic and barrier-damaged skin. It is extremely well tolerated, soothes irritated and stressed skin and can also be used on its own or in combination with oils as a balm. In formulations, it acts as a natural consistency enhancer and produces smooth creams that are easy to apply and have a high penetration capacity due to their high content of unsaponifiable and oleic acid. Such an ingredient simply cannot be missing in a top-class face cream.
