Several skin conditions have a genetic component. Genodermatoses is the medical term used to describe genetic dermatological disorders. With most skin conditions, there is also an environmental aspect or trigger that activates the symptoms. This is generally true even when there is a genetic component. This means that the environment and lifestyle of the individual is also important. More common skin conditions include acne, atopic dermatitis (eczema), shingles, hives, sunburn, contact dermatitis, rosacea, psoriasis, and vitiligo.
