When most people think of fake tan, they imagine a golden lotion or a bronzed mousse that gives instant sun-kissed skin. But here’s the surprising truth: the active ingredient in fake tan is actually colourless.
At Beaubronzage, we believe that understanding how tanning products work helps our clients get the most flawless results, so let’s take a closer look.
The Science of Sunless Tanning
Fake tans work thanks to an ingredient called DHA (dihydroxyacetone). DHA is a simple sugar that reacts with amino acids in the top layer of your skin. This reaction gradually darkens the skin’s surface, producing the golden tones we associate with a natural tan.
What makes this process interesting is that DHA itself has no colour. It is completely transparent. The bronzed shade only develops as your skin responds to the ingredient, usually taking between 4 and 8 hours to appear.
Why Do Some Fake Tans Look Tinted?
If DHA is clear, why do some products look brown or golden straight from the bottle? The answer is that many brands add a cosmetic “guide colour”. This temporary tint makes application easier, since you can immediately see where the product has been applied. The guide colour washes away with your first shower, leaving behind the real tan that has developed underneath.
The Advantages of a Colourless Tan
Choosing a clear tanning formula comes with its own set of benefits:
-
Less transfer – Colourless tans are less likely to stain sheets or clothing.
-
Natural development – The tan appears gradually, helping to avoid streaks or patchiness.
-
Buildable results – You can control the depth of your tan by layering applications over time.

At Beaubronzage, we specialise in creating natural-looking tans that suit every skin tone.
