Guest guest Posted June 5, 2002 Report Share Posted June 5, 2002 Well, I don't know about decreasing skin sensitivity, BUT: I have had highly sensitive, allergic skin all my life, long before I developed rosacea. There are very few products I can use on my face. I even had an allergic reaction to MetroLotion. Yet, Nivea Creme is one of the few products I can use with no problems. I am referring to Nivea " classic " , the one in the blue jar or tube, not Nivea Visage, which caused the usual allergic reaction on my face. I've never been able to figure out what in most products causes me to have an allergic reaction, but I've always assumed fragrance was one of the triggers, since it seems to be for so many people. Yet, Nivea Creme is heavily fragranced. It is smelly, heavy, and greasy, and yet really soothes my skin. I use it at bedtime only - it is too heavy and greasy to use for the day time. Nivea Cream This little gem was buried in the skin sensitivity article posted by Matija: " Using the lactic acid assay [the test used to determine presence and degree of skin sensitivity], researchers have demonstrated that emollients can be used to prevent the stinging response. The results of those studies also show that there is a hierarchy of protectiveness, with the benefit provided increasing with growing hydrophobicity of the emollient agent. In addition, it has been possible to convert stingers to nonstingers after several months of twice daily treatment with Nivea cream. " Am I reading this correctly? Nivea cream can decrease skin sensitivity? Here's the ingredients: Water, Mineral Oil, Petrolatum, Glycerin, Isohexadecane, Microcrystalline Wax, Lanolin Alcohol, Paraffin, Panthenol, Magnesium Sulfate, Decyl Oleate, Octyldodecanol, Aluminum Stearate, Fragrance, Methylchloroisothiazolinone, Methylisothiazolinone, Citric Acid, Magnesium Stearate Ouch! Lots of stuff that doesn't look good. This is for the body, but their Nivea Visage line for the face doesn't look like it has anything related to Nivea Cream. This was the sole reference to Nivea Cream that I found in Medline: Acta Derm Venereol 1999 Mar;79(2):115-7 Correlation between the greasiness and the plasticizing effect of moisturizers. Jemec GB, Wulf HC. Department of Dermatology, Bispebjerg Hospital, University of Copenhagen, Denmark. ccc2845@... " Moisturizers are used as cosmetics and as adjuvant therapy in dermatology. The strength or relative efficacy of moisturizers is poorly described and thus advising patients is difficult. It has been suggested that lipidization of the skin by moisturizers and the changes in skin mechanics following the application of a moisturizer may be useful measures of outcome. The aim of this study is to describe the relative efficacy of 5 different moisturizers, a barrier cream and a gel in terms of changes in skin mechanics and electrical capacitance before and after application. Assessment of the greasiness or absorption of the cream was made by standardized blotting of unabsorbed residue. Lipid-rich creams (Vaseline, Locobase and Decubal creme) caused increased skin distensibility, while no differences were found in hysteresis changes. In contrast, the relative efficacy in increasing skin capacitance was significantly greater in the moisturizers with a lower lipid content (Clinique, Nivea) and gel. The results suggest that lipidization is of major importance to the plasticity of the skin. When moisturizers are used to improve skin plasticity it is suggested that lipid-rich formulations be used. Cosmetically more acceptable creams and gel were however better at increasing skin capacitance which has been interpreted as a measure of skin hydration. The difference may reflect a design adaptation of these creams to a specific outcome measure and our results raise the question of appropriate outcome measures in future moisturizer studies.
