Skin creams vary in thickness, but are traditionally thicker than lotions, which have a higher concentration of water. Many people use the terms "cream" and "lotion" interchangeably. Depending on the type of skin cream you use, you can soften, protect or medicate your skin. Because allergic reactions or irritation may occur with topical treatments, always test a new cream out on a small area of skin before proceeding with a full application.
Medicated Creams
You can purchase mediated skin creams either with or without a prescriptions. These creams deliver topical mediation to your body through the skin. Some medicated skin creams treat specific skin-related problems while others are merely a vehicle through which mediation is delivered to deeper tissues within your body. Medicated creams may give off an unpleasant odor. Some examples of medicated creams are hydrocortisone cream, deep-muscle rubs and retinol creams. A 2008 CNN health report cautions consumers against using more than the recommended dosage of medicated creams as the active ingredients can be toxic--even fatal--in large amounts.
Moisturizers
Moisturizing creams add moisture to dry or damaged skin. According to the New Zealand Dermatological Society, moisturizing creams often contain emollients that soften skin in addition to restoring skin's natural oils. Dry skin can arise as a result of dry, chilled conditions or advanced age, since the skin naturally retains less oil as you grow older. Frequently taking long, hot showers can also deplete your skin's moisture level and leave you in need of a moisturizing cream. Although moisturizing creams are not traditionally medicated, they may be beneficial in easing the discomfort of some medical conditions, such as dermatitis, that dry out your skin.
Cosmetic Creams
Cosmetic creams claim to help improve your appearance. Often, individuals use cosmetic creams to reduce the signs of aging. One common ingredient in cosmetic creams is caffeine. Used to reduce redness, tighten skin and even skin tone, caffeine commonly appears in facial creams and cellulite creams. Some cosmetic creams won't affect your appearance but give off powerful fragrances and can be used in lieu of perfume or cologne. Unfortunately, scented cosmetic creams are responsible for allergic reactions more often than any other variety of skin cream.
Sunscreen
Sunscreen is a protective cream that protects your skin from sun damage and wrinkles. Sunscreen also helps prevent skin cancer by forming a barrier between your skin and the sun's rays. Sunscreen comes in a variety of strengths and may protect you from harmful UVA rays, UVB rays or both. The American Academy of Dermatology recommends that you apply sunscreen a minimum of 30 minutes before sun exposure to give it time to form a adequate barrier. Its important to apply sunscreen across your entire body rather than only the areas receiving direct sun exposure. Sun rays pass through clothing and not all garments provide you with adequate protection.
