Sunless tanning (also known as spray tanning, self tanning, fake tanning, or UV-free tanning) refers to the application of chemicals to the skin to produce an effect similar in appearance to a suntan. The popularity of sunless tanning has risen since the 1960s after links were made by health authorities between exposure to the sun, and other sun tanning methods, such as sunbeds or tanning beds, and the incidence of skin cancer.
The most effective sunless tanning involves the use of lotions and sprays that contain dihydroxyacetone (DHA) as the active ingredient. DHA is not a dye, stain or paint, but causes a chemical reaction with the amino acids in the dead layer on the skin surface. This is similar to a reaction well known to food chemists called the Maillard reaction. This refers to the browning process during food manufacturing and storage. It does not involve skin pigmentation nor does it require exposure to ultraviolet light to initiate the color change. The effect is temporary and will fade gradually over 3 to 10 days.
Some products use erythrulose combined with DHA. Erythrulose works identically to DHA on the skin surface, but develops more slowly. The two chemicals used together may produce a longer lasting sunless tan.
Dihydroxyacetone or erythrulose may cause contact dermatitis. First time users of sunless tanning products are advised to apply the product to a small patch of skin and wait 24 hours before a full body application.
These products can be applied at home, in the form of gels, lotions, mousses, sprays and wipes. Best results are obtained when applied to clean, dry skin. Bathing and swimming should be avoided until product is fully absorbed, which varies from one to six hours. More DHA is absorbed by the thicker skin on the hands and feet, so those areas should be skipped or cleaned immediately after application.
Tanning lotions can be classified as bronzers, accelerators, and tingling lotions. Tingling lotions refer to indoor tanning lotion accelerators and maximizers that produce a tingling sensation when they are applied. It is believed that the tingle factor increases blood flow to the upper layers of the skin which brings more oxygen and affects melanin. This tingling sensation will vary depending on the skin type from mild to very strong.
Professional spraytans applications are available from spas, salons and gymnasiums by both hand held sprayer and in the form of sunless or UV-Free spray booths. The enclosed booth, which resembles an enclosed shower stall, sprays the sunless tanning solution over the entire body.
The U.S. Food and Drug Administration (FDA) states when using DHA-containing products as an all-over spray or mist in a commercial spray "tanning" booth, it may be difficult to avoid exposure in a manner for which DHA is not approved, including the area of the eyes, lips, or mucous membrane, or even internally. DHA is not approved by the FDA for inhalation.
DHA has been approved for cosmetic use by the FDA, Health Canada and most of the EU member nations. It is considered nontoxic and noncarcinogenic. Because DHA does not use the skin's melanocytes to make the skin a tan color, it is recommended as a cosmetic disguising cover for vitiligo patients. DHA based sunless tanning has been recommended by the Skin Cancer Organization, the American Academy of Dermatology, the American Cancer Society and the American Medical Association.
5 Benefits Of Sunscreen:
Keeps Complexion Even Using sunscreen on your face helps to keep your complexion even. Sun damage is one of the many causes of uneven skin tones and daily sun cream helps to prevent those effects.
Sun Protection One of the most obvious and notable benefits of sunscreen is that it protects your skin against the sun’s broad spectrum of harmful UV rays. Sunscreen actually minimizes the penetration of UV rays into the skin and the triggering of a variety of skin disorders. Even the mildest of sunburns2 can have damaging effects so it is important to protect your skin.
Helps Protect Against The Visible Signs of Premature Aging We all want youthful, radiant, and healthy looking skin. But overexposure to sunlight can increase the appearance of fine lines and wrinkles3. In other words, using sunscreen can help protect against the harmful effects of premature aging or skin aging.
Reduces Risk of Cancer Fortunately, sunscreen is very effective in reducing the risk of developing a variety of skin cancers, especially melanoma4. This type of skin cancer is known to be extremely aggressive and can be life-threatening for many women, particularly those in their 20s. However, you must apply sunscreen daily to see the cumulative protection over the days and months.
Healthy Skin Overall Michelle stresses to her clients that "skin is healthier overall when you use sunscreen." Essential proteins in the skin like keratin are protected when sunscreen is applied. These proteins are primarily responsible for keeping the skin smooth and healthy both in appearance and function.
