The fact is, that new understandings in the actual intrinsic functions of the skins sub epidermal processes has led to the development and discovery of many new therapeutic substances. Most of these new substances, in fact, actually occur in a natural form in the skin itself but may be lacking due to a degradation of the skins natural functions as a result of aging or sun exposure. By synthesizing and chemically engineering these substnces, they can then be highly effective in topical skin treatments as a form of replacement therapy. Also, elements such as vitamins A and E which are oil based can be made water soluble by chemically engineering them into “acidic form”.
Effective in the Dermis Irritating to the Epidermis
So, while highly effective in the skins underlying dermal layer, these substances contained in so many Obagi products can, in fact irritate the skins surface. This particularly holds true when they are applied in concentrated form, which is so often the case. Obagi NU-Derm Tolereen was created as a skin product for the skin irritation that so often is a side effect of using newer more effective products. Also, many times, such as in the treatment of acne or with chemical based exfoliators, the skin may be sensitive to begin with. Obagi NU-Derm Tolereen is specifically formulated with hydrocortisone to effectively treat skin irritation brought on as the result of using Obagi skin treatment products.
Powerful Chemical Substances Bring a Risk of Mild Irritation
Why use Obagi Tolereen and not some other “skin soothing” product? Obagi Tolereen is specially formulated not to interfere or react with any of the substances that are contained in Obagi skin care products. The fact is, that in the vast majority of skin irritation cases brought on by the use of Obagi products, the irritation is only temporary. However; with skin treatment products that can cause more longer lasting irritation Obagi makes available these products in more than one concentration level. Remember, there are products on the market that don’t cause irritation but they are all “feel good” creams and lotions that rely on oils and perfumes. “Truly effective” skin care products that contain “powerful substances that penetrate” the skins surface can at times cause initial skin irritation.
