Suntan products are available in various different forms – from sprays to lotions to accelerators. The user should try to choose a tanning product that he or she is most comfortable with. However, for a dark self-tan, it's advisable to use an ultra dark self-tanning lotion from a reputable company.

All tanning creams for dark spots consist of Dihydroxyacetone (DHA). DHA is basically a type of sugar that interacts with the skin cells (dead ones) that are located in the upper layer of the body. As this sugar intermingles with the cells, the skin starts to change its color. This change normally lasts for about a week after the application.

Self-tanning products will not work well on the skin that is rough or chapped; in fact, it will only make it look more patchy and streaky. To make sure that one gets the desired tan, a good moisturizer must be applied to the entire body for a week or two before using a self-tanning lotion.
