How Spray Tanning Works

The short version

A trained technician applies a fine mist of tanning solution evenly across your skin. The active ingredient reacts with amino acids in the outermost layer of your skin, gradually turning it a sun-kissed brown over the following hours. No UV light is involved at any point — the color is purely cosmetic and sits in skin cells your body naturally sheds over the following week or so.

Why the color develops over hours

• The reaction is gradual — most of the depth appears within the development window your technician sets.
• The immediate color you see is a cosmetic bronzer that shows where solution has been applied.
• Your first rinse removes the bronzer and reveals the developed tan underneath.

Why 'custom' matters

Because the color comes from a reaction with your skin, the same solution reads differently on different people. That's why the studio matches the formula and depth to your skin tone, timing, and goal — custom color is what separates a natural glow from an obvious tan.
