How the Skin Creates a Sunless Tan
What is DHA?
The active ingredient in California Tan's sunless tanning solutions is Dihydroxyacetone (DHA). DHA was initially discovered in the 1920's but was first used as a tanning agent in the 1960's. It is derived from sugar beets and for over 4 decades scientists have studied it's tanning mechanics, skin tolerance and physiochemical properties. Coppertone were the first to sell an over-the counter product - Quick Tan. Unfortunately Quick Tan's streaks and orange colour quickly encapsulated everything viewed as negative about sunless tanning! Thankfully formulations have moved on somewhat since then and the tan you can expect from any of the California Tan Range is golden, and most of all natural!
How does it work?
DHA reacts with proteins, including amino acids in the outermost layers of the skin to effectively dye the skin. Because the colour change only occurs on approx the first 2-3 layers of skin, as the skin sheds, so does the colouration. Skin replaces itself naturally every 28 days. Therefore most sunless tans will not last much longer than 4-7 days. This can be prolonged by using the California Tan, Tan Extender. (See the self tan lotions in the product guide)
Is DHA safe?
• Close eyes during spay applications
• Purse lips (cover lips) or apply lip balm during spray applications
• Avoid directly breathing in solution during spray application
• Do not ingest any of the products
