How Self Tanning Lotion Achieves A Sun-Kissed Color

By Haywood Hunter


To understand how these lotions work, sometimes learning about the design of the skin can help get the depth of color desired as well as determine the best self tanning lotion for you. Basically, the skin has two layers. The outer layer is called the epidermis and the inner layer is the dermis.

Self tanning lotion darkens the outer layer of the epidermis whereas sunbathing darkens the inner layer. This is called the stratum basale layer which can be damaged easily by direct sunlight. A disadvantage of this product is that few contain sunscreen, but when used properly is safe.

The outer layer of the epidermis is called the stratum corneum and at this layer, self tanning lotion works. Since this product was first invented, it has focused on changes on this level in order to help those with the desire achieve that sun-kissed look. The goal is to find the right lotions that work on the outer epidermis.

The first to introduce self tanning lotion was Coppertone, who released their product in 1960. Since that time many changes have been made as it originally turned skin orange. The result is tanning products that can turn skin from a dark tan to anything lighter with applications using various methods.

Self tanning lotion often takes between 45 minutes to one hour before it starts working, then another two hours to dry. However, with self tanning lotion containing dihydroxyacetone the color lasts between five to seven days. This is because this ingredient interacts with dead skin cells in the epidermis turning them dark.

With newer types of self tanning lotion on the market today it is easier than ever to maintain the color desired. Moisturizers, sprays, and powders are convenient forms of self tanning lotion and easy to apply. When going outside, however, sunscreen will need to be used in addition to self tanning lotion.
