This reaction produces the bronzing color effect, which wears off as the affected skin cell layer naturally dies and peels off. Another important aspect of tanning oils are the moisturizers that are often included as active ingredients. The process of tanning can quickly dehydrate the skin. The addition of moisturizers, such as vitamin E and glycerin, helps protect the skin by keeping in moisture, or by drawing moisture from the air to moisturize the skin. Although more tanning oils are starting to use SPF protection, most still do not provide enough of a barrier against the harmful effects of ultraviolet radiation, especially UVB radiation.
In fact, few tanning oils provide more than an SPF 4 level of protection. UV rays have the ability to damage skin cells, which can mutate the cell's structure. These mutations can create a cancerous cell, which can lead to skin cancer, according to the Skin Cancer Foundation. The American Academy of Dermatology recommends using a broad-spectrum protects against UVA and UVB rays , water-resistant sunscreen with an SPF of 30 or higher and reapplying every two hours or as often as the product's label states in order to help prevent sunburn, early skin aging and skin cancer.
How long should I wait after applying it to go in the sun, and how long can I stay in the sun with it on? And how does it work anyway? The active ingredient does the sun protection work. These come in two categories: UV absorbers and UV reflectors.
UV absorbers are chemicals that absorb UV radiation and convert it to a very low level of heat. Some absorb the UVB part of the spectrum, which is known to cause sunburn and contribute to skin cancer risk. Others absorb the UVA part of the spectrum. Recent research suggests the longer UVA wavelengths not only penetrate to deeper layers of the skin but contribute to skin cancer through compromising immune response to DNA damage.
There is normally more than one and often up to six or more active ingredients in most sunscreens. The emulsion — the lotion, milk, cream, oil, foam or gel — is what carries the active ingredient. It is usually made up of some combination of oil and water, plus other goodies. These are important as they preserve the product so it lasts on the shelf or in your cupboard. They also help with water resistance, influence how the sunscreen feels and smells, and how well it binds to the skin.
Sunscreen provides a screen , not a block. In the same way, the sun lotion or potion of your choice allows some small amount of UV radiation onto your skin.
SPF stands for sun protection factor. The higher the number, the less UV passes through. An SPF of 30 allows one-thirtieth or 3. When applied, dihydroxyacetone reacts with dead cells in the skin's surface layer to temporarily darken the skin and simulate a tan.
The coloring typically wears off after a few days. Most sunless tanning products don't contain sunscreen. If a product contains sunscreen, the sunscreen will be effective only for a couple of hours. If you spend time outdoors, sunscreen remains essential. Sunless tanning pills, which typically contain the color additive canthaxanthin, aren't safe. When taken in large amounts, canthaxanthin can turn your skin orange or brown and cause hives, liver damage and impaired vision.
Topical sunless tanning products are generally considered safe alternatives to sunbathing, as long as they're used as directed. However, the FDA states that DHA shouldn't be inhaled or applied to areas covered by mucous membranes, including the lips, nose or areas around the eyes because the risks of doing so are unknown. If you're using a sunless tanning product at home, follow the directions on the label and don't get the product in your eyes, nose or mouth.
If you're going to a sunless tanning booth, ask how your eyes, mouth, nose and ears will be protected and how you will be protected from inhaling the tanning spray.
