Allow a few minutes for the tan to absorb before dressing. The initial tan colour you’ll see is actually the cosmetic guide colour. Only apply loose dark clothing.
Whilst your tan is developing:

The tan will typically require between 6 and 8 hours developing time (depending on the product used). Therefore keep your skin completely dry, avoid water contact for this period.
Do not apply any products over the developing tan.
Avoid other beauty/hair treatments whilst tan is developing.
Avoid activities that make you perspire.
Drink hot beverages through a straw as contact with a hot cup can strip colour from around your mouth.
Toothpaste can also strip colour while your tan develops.
After your tan has developed:

Rinse off remaining colour guide with warm/hot water. Once the water runs clear gently wash yourself with a mild soap.
Avoid products that contain alpha hydroxyl acids (AHA’s) as they can strip colour.
Avoid swimming pools as chlorine will prematurely fade your tan.
To prolong your tan use St. Tropez Tan enhancing body moisturiser daily. This will lock in colour and hydrate your skin.
