La Femme Tanning Treatments

Self-tanning occurs in the top layers of your skin called the epidermis. The epidermis is also made up of layers. The stratum corneum (or Horny Layer) is the layer affected by self-tan products. 

St. Tropez self-tan products contains the naturally-derived, premium tanning agent called DHA. St. Tropez self-Tans also contain a cosmetic guide colour. This assists your application, showing you where you have applied the self-tan. It also gives your skin an instant sun-kissed look. However, this is simply cosmetic and washes off to reveal a gorgeous fake tan.
