3 Facts You Must Know About Ingredients

Not all skincare products are created equal.  In fact, there can be vast differences between manufacturers, products that claim similar results and even within different batches of the same product by the same manufacturer.  How do we get the consistency in performance and results with Renée Iverson Skin Therapy? The key is in the ingredients.     

1) Performance Ingredients are Dose-Dependent—Not Over-Dose Dependent

Just as the activity of aspirin or other drugs depends on their dose, the same it true for performance ingredients in cosmetics.  You wouldn’t take half an aspirin for a headache, nor would you take the whole bottle.  Performance ingredients must be used at dose-dependent levels in the same way as drugs or the promised results will not be seen or felt in the skin. Renée Iverson Skin Therapy uses the percentages determined in laboratory and clinical studies to ensure that you don’t get too little - or too much - of an ingredient.  We like to call this the “Goldilocks Rule of Formulating”: the amount of each action ingredient is “just right”. Proper amounts of ingredients to do the job - dose dependency, is one of the biggest differences between Renée Iverson Skin Therapy products and those made by other companies.

2) Ingredients on the Label May No Longer Be In the Product

Some ingredients are fragile.  They don’t do well when exposed to air, sunlight, extreme heat or, in some cases, extreme cold -  and some interact with other ingredients in the product.  When this happens, one or both ingredients can be inactivated, or a totally new substance can form.  The most sensitive ingredients are antioxidants from plants, vitamins, minerals, lipids, amino acids, peptides and proteins.  The chemists and biochemists who create Renée Iverson Skin Therapy understand the fragility of ingredients, so they find ways to prevent interactions.  Their efforts ensure the ingredients you see on the label are actually present at the time you use the product.

3) Not All Plant Extracts are Created Equal

Just like everything else in the universe, plants are made of chemicals.  These chemicals - known as phytochemicals - can vary from plant to plant and can be affected by soil quality, time of harvest and processing method.  In addition, certain extracts are “chemically standardized” meaning they contain measured levels of specific phytochemicals while other extracts of the same name do not.  An example is Green Tea, a plant rich in epigallocatechin gallate (ECGC), caffeine and ellagic acid.  Green Tea that has been tested  to contain ECGC’s will deliver strong antioxidant and soothing therapy to the skin.  When tested to contain caffeine, Green Teas have tested positive for cellulite control. Green Teas with ellagic acid may be good for identifying toxins for removal in the body.  To our knowledge there is no Green Tea extract that offers chemically standardized amounts of all three phytochemicals.  Renée Iverson Skin Therapy products use chemically standardized extracts from natural ingredients so you can be sure that the ingredients in the products are actually doing the job!
