Collagen type II is POSSIBLY SAFE when taken by mouth in doses up to 2.5 mg daily for up to 24 weeks. Itâs not clear what the side effects might be. Other collagen products, such as bovine collagen and gelatin, have caused allergic reactions.
Puffy lips are often the result of allergic reactions. These allergic reactions can lead to a condition that causes short-term swelling to occur beneath the surface of the skin, a condition known as angioedema. Puffy or swollen lips may also be caused by other conditions, such as an infection, injury, or certain hereditary conditions.
Contact dermatitis is another possible cause of itchy or flaky eyelids. This is a type of eczema triggered when the skin comes into contact with something you are irritated by or allergic to, such as make-up. The condition usually clears up after you stop using the substance your skin is reacting to.
