Bronzing/Self Tanning
Both excessive sunbathing and the intense use of tanning beds bear the risk of serious consequences for the human being's health. Sunless self tanning with dihydroxyacetone (DHA) is an adequate method to achieve a significant tan within just a few hours.
Once DHA is linked to the amino acids on the skin surface, the tan can last for up to two weeks. It can only be removed mechanically or is diminished by natural exfoliation.
Classical Self Tanning Applications
In the latter decades of the twentieth century the self tanning market was dominated by the classical cosmetic applications such as emulsions, gels, sprays, foams and even wipes. All formulation types need to be fine-tuned according to the body zone for which they are designed. Typical concentration is about 5 % dihydroxyacetone (DHA).
Instant tan effects can be achieved by addition of dyestuffs or small amounts of pearlescent pigments. Active ingredients can also optionally be added (UV filters, vitamins, etc.).
Modern Self Tanning Applications
Since the turn of the millennium, formulators have created compositions that allow applications to be controlled, thus enabling skin coloration of unsurpassed uniformity to be obtained. Sunless tanning booths and non-shower spray systems are nowadays beautifying consumers with an impeccable and uniform tan, covering even those body regions which are normally impossible to access. Shower applications are intended for use from head to toe, airbrush lotions with DHA are used to create ´short-term´ tattoos.
DHA in Day Care Applications
The recent launch of a range of day care products containing the self-tanning ingredient really established the novel but self-evident potential of DHA. Routine daily use of this new product class containing a lower amount of DHA than normally used provides a light tan with a natural glow all year round.
