What is an allergic reaction
An allergic reaction is very much less common than irritative reactions. During life, we estimate that approximately 2% will develop an allergic reaction to a cosmetic product. Allergic reactions manifested in skin contact dermatitis. For such a reaction to take place, one must first develop an allergy. Upon initial use of a drug (new cream) will never get an allergic reaction. The body must first develop an allergy. For prolonged use may immune system develop such a sensibility (allergy). This process is called technical term sensitization. Once one has become sensitized, even very small amounts of the product provide a dermatitis reaction in the skin. Typical allergic reactions are swelling, scaling and purses skin changes.
