- The active ingredient in self-tanning lotion is dihydroxyacetone (DHA). According to aad.gov (American Academy of Dermatology) DHA is a colorless sugar that reacts with dead skin cells located in the stratus corneum skin layer of the epidermis. But, the fake-bake tan that is achieved only lasts as long as the dead cells remain on the surface of your skin, which is approximately 5 days. As the cells naturally slough off, they take the DHA with them, making it necessary to reapply the self-tanning lotion.
- Although self-tanning lotion has gotten a bad rap over the years, many pitfalls associated with self tanners can be avoided if they are applied properly. In fact, if the application process is done correctly, you will have no problems with streaking, and your skin should not turn orange. Keep in mind that DHA is a stain, and where it lands on the skin, is where it will undergo its color change.
- Skin cells slough off at different rates, and if you apply a self-tanning lotion without exfoliating first, staining will be uneven. Not only will the DHA adhere to those skin cells that have recently died, it will also stain those skin cells beginning to fall off. So, exfoliating with a scrub or shaving the day before the application of a self-tanning lotion will ensure an even, sunless tan. It is also important to apply the sunless tanning lotion evenly. If you do not rub it in well, or apply it heavier in some areas than others, the results will be less than appealing. Also, remember to wash your hands immediately afterward to avoid staining.
- Choose a self-tanning lotion that will enhance your skin. If you have light skin and usually burn in the sun, choose the self-tanning lotion accordingly. You will achieve a better result by purchasing a self-tanning lotion that is light or fair. If you tend to tan easily in the sun, tanning lotions that are labeled medium or deep may be for you.
