There are different ways of tanning, sun tanning, bed tanning and self tanning. Some consider self tanning safer, faster and can achieve a beautiful tanning without getting burnt. According to dermatologist Robin Ashinoff, MD, of Hackensack University Medical Center in New Jersey : "It's certainly much better than going out or going to a tanning salon and getting exposed to UV light,"
There are two kinds of self tanning, cosmetic bronzer that can be released when washed and other kind can varnish the skin and will fade when cells are shed off. Experts say that sunless tanners require more preparation than a cosmetic bronzer. It is preferable to not to use self-tanning all over your body and face you must get self tanning designed to use on face and must choose the right color that suits you (light, medium or dark formula).
Self tanning can be found in drug stores in a form of lotion, gels, sprays (wear protective gear for the mouth, eyes and nose to protect the mucous membranes and lungs) or mousse and they all contains dihydroxyacetone (DHA) which is sugar that is very safe to use and it interacts with proteins in the outermost layer of skin to produce a darker skin color or fake tan and may last between 3 to 7 days.
When apply self tanning it is preferable to take a shower first, wait till the body is well dried then add a thin layer of moisturizing, before starting make sure to use latex gloves to protect your hands, then spread self tanning material well all over your body and be careful around wrinkles or areas that tend to be drier -- such as knees, elbows, and ankles and avoid around eyes, nose and mouth; wait till body is well dried and dress after 30 min, avoid shower, sweating and reapplying tanning for 8 hrs. Avoid using moisturizer, lotion, or deodorant after putting self tanning, which can interfere with even absorption of the tanner. In case some parts are too dark you can lighten it by applying hydrogen peroxide, baking soda, lemon juice, cream bleach or whitening toothpaste.
Most dermatologists consider self tanning is much safer than obtaining a tan from ultraviolet (UV) radiation that comes from the sun or tanning booths.
Self tanning is more healthier than UV radiation, tanning beds and booths but better not use it regularly and always check the SPF ratings of the product and avoid using sprays. Using it very rarely and on occasions may not be dangerous. Follow the FDA regulation on self tanning products for safety and recommendations.
To be on the safe side, if u want to stay tanned all over the year and have a healthy anti-age skin it is much preferable to have a healthy diet rich in carrots and tomatoes… and stay away from artificial tanning and avoid UV radiation by wearing special sun suits and using appropriate sunscreen.
