Can I use Collagen Aktiv products if I have skin sensitivities and allergies?

es, in fact, our products are well suited for individuals with sensitive skins. If you are concerned about the possibility of an allergic reaction to our product, however, we recommend this simple test. Apply a small amount of Collagen Aktiv to damp skin on the inside of your elbow for three days. If a rash or blotchiness develops, discontinue use.
