How a spray tan works - Tanning Southend
DHA is the main active ingredient in spray tanning solutions. DHA is FDA approved and works by reacting with amino acids in the surface skin cells to create a tanned appearance.
The main active ingredient is Dihydroxyacetone, or DHA, which is actually CLEAR in colour, so tanning solutions have a COLOUR GUIDE added, so we can see where the tan has been applied.
Because of the dangers of excessive exposure to the sun, such as the risk of skin cancer, brown spots and premature aging, spray tanning has become a popular alternative to tanning via the sun. A spray tanning session only takes about ten to twenty minutes to complete.
the epidermis on the outside and the dermis on the inside. Whether you are talking about sun tanning or self-tanning, the epidermis is where the action occurs. The epidermis is also made up of layers. The deepest layer of the epidermis, called the stratum basale (basal layer), is affected during sun tanning. The stratum corneum (horny layer) is the outermost layer of the epidermis -- it is this layer that is affected by most sunless-tanning products.
There are several different kinds of sunless-tanning products available today. People have been able to pour on a tan since 1960, when Coppertone® came out with the first sunless-tanning product -- QT® or Quick Tanning Lotion. If you are old enough to remember this, then you are probably thinking of the incredibly orange hue this lotion produced. Since then, there have been several advancements made on the sunless-tanning front. These days, you can find tanning pills, sunless- or self-tanners and bronzers. You can smooth, swipe or spray on a light bronze glow or a deep, dark tan. Many of these products take 45 minutes to one hour to start taking effect, and once you factor in drying time, you could be looking at about three hours spent achieving that sun-free tan.
