Our skin is made up of two layers: the outer layer is the epidermis and the inner layer is the dermis. The outer most layer is called stratum corneum and this is this layer that is affected by most sunless-tanning products. Our Solution contains dihydroxyacetone (DHA)which acts as the active ingredient. DHA is a colorless sugar that interacts with the dead cells located in the stratum corneum of the epidermis. As the sugar interacts with the dead skin cells, a color change occurs resulting in a tanned appearance. This change usually lasts about five to seven days from the initial application. Every day, millions of dead skin cells are sloughed off or worn away from the surface of your skin. In fact, every 35 to 45 days, you have an entirely new epidermis. This is why your sunless tan will gradually fade – as the dead cells are worn away, so is your tan. For this reason, we suggest that you reapply your sunless tan about every 8 days to maintain your “tan”. Our Solution is enhanced with bronzers. The bronzers help to give you an immediate tan result. This tan can easily be removed with soap and water and will wash off while your DHA tan stays on your skin. It’s important to remember that this solution will not protect you from the sun’s rays.
