Rashes—Cosmetics

Also called: Makeup

Cosmetics are products you apply to your body to clean it, make it more attractive, or change the way it looks. They include

• Hair dyes
• Makeup
• Perfumes
• Skin-care creams

Cosmetics that treat or prevent diseases are also drugs. Products such as dandruff shampoo, fluoride toothpaste, and antiperspirant deodorant are both cosmetics and drugs. A good way to tell if you’re buying a cosmetic that is also a drug is to see if the first ingredient listed is an “active ingredient.” The active ingredient is the chemical that makes the product effective. The manufacturer must have proof that it’s safe for its intended use.

Cosmetics can cause allergic reactions. The first sign is often red and irritated skin. Fragrances and preservatives are the most common causes of skin problems.

To find out all the ingredients in a cosmetic you use, check the container. Manufacturers are required to list them. Labels such as “natural” and “hypoallergenic” have no official meaning. Companies can use them to mean whatever they want.

Also called: Dermatitis, Skin rash

A rash is an area of irritated or swollen skin. Many rashes are itchy, red, painful, and irritated. Some rashes can also lead to blisters or patches of raw skin. Rashes are a symptom of many different medical problems. Other causes include irritating substances and allergies. Certain genes can make people more likely to get rashes.

Contact dermatitis is a common type of rash. It causes redness, itching, and sometimes small bumps. You get the rash where you have touched an irritant, such as a chemical, or something you are allergic to, like poison ivy.

Some rashes develop right away. Others form over several days. Although most rashes clear up fairly quickly, others are long-lasting and need long-term treatment.

Because rashes can be caused by many different things, it’s important to figure out what kind you have before you treat it. If it is a bad rash, if it does not go away, or if you have other symptoms, you should see your health care provider. Treatments may include moisturizers, lotions, baths, cortisone creams that relieve swelling, and antihistamines, which relieve itching.
