Before starting to use Tan in a Tube, make sure you have exfoliated your skin a couple of times before application. Also, remember that dry skin is more absorbent. To avoid dark patches on extra dry areas, such as knees and elbows, moisturise them with a regular Body Lotion before applying Tan in a Tube. This will help you achieve more even colour. Avoid the hairline and the eyebrows. Also, avoid creating sharp lines by smudging Tan in a Tube. Do not forget to wash your hands thoroughly afterwards! It may take up to eight hours for the full effect to reveal itself. The tan will be natural and you need to repeat the application several days in a row to achieve a deeper tan. The colour will wear off gradually. Apply Tan in a Tube every three to five days, to maintain the tan. Careful with your clothes! Do not get dressed until the product has been completely absorbed by the skin. Tan in a Tube is perishable. Once opened, it should be used up within six months.
