Four weeks prior to treatment, you will undergo a skin test to insure there is no allergic reaction to collagen. The test is similar to a tuberculin skin test. Your skin will be examined at 48 hours and at 4 weeks for any hypersensitivity reaction. Redness, swelling, itching and/or firmness of the skin test site are considered an indication of allergy and Dr. Stevens may advise against the use of collagen if these signs are present. About 1 to 4 percent of individuals develop hypersensitivity reactions.
If the four week test results are negative, Dr. Stevens will perform a second skin test. At the end of two weeks, your skin area will be evaluated for any signs of allergic reaction. If you do not show any adverse reaction to the skin test, then you can begin treatment with collagen.
