The Ultimate Colour Booster brings your tan back to life. The TAN EXTENDER is a perfect compliment to the dark tanning lotion, mousse or mist. This white, moisturising lotion contains a modest concentration of active tanning ingredient without the dark "instant" colour. It can be easily applied to "extend" your XEN-TAN days or weeks longer.Just starting out? TAN EXTENDER is perfect for those individuals new to sunless tanning. The smooth white lotion is easily applied and the "medium" level of tanning agent provides a beautiful medium tan or adds more depth to your darker tan from the lotion, mousse or mist! TIPS: Apply 4 or 5 Days after you have applied your tanning product (Lotion/Mousse/Mist), and it really boosts the colour, extending the life of your tan thus making your bottle of self-tan last so much longer (another great money saving-tip).
