What it is
A full exfoliation first, then Sienna X tinted self-tanning lotion applied by hand across the whole body. Applying it manually rather than spraying it in a booth is what stops the streaks and the tidemarks.
The depth of colour you end up with depends on your own skin tone, so it lands as a believable version of you rather than a uniform shade. It works on every skin type, and on men as well as women.
Before your appointment
Do not use any other self-tanning product for at least four days beforehand, and do not wax or shave within 24 hours of your appointment.
Come in loose, dark clothing with a dark bra or none at all, since the guide colour can stain nylon and wool. Black paper tangas are provided when you arrive.
Skip perfume, deodorant and aromatherapy oils on the day. They interfere with how the tan develops.
The first twelve hours matter
Do not shower or bathe for at least four hours, because the colour is still developing. It is fine to leave the guide colour on overnight and shower in the morning, and it washes out of cotton.
Do not do anything that makes you perspire for at least twelve hours, and do not swim for at least twelve hours either. Pool chemicals bleach a spray tan the same way they bleach a real one.
Wear loose clothing afterwards. Tight waistbands leave marks in exactly the places you will notice.
Making it last
Moisturise daily and exfoliate every other day so the colour fades evenly rather than patchily. We stock the Sienna X body moisturiser and body polish, and a sunscreen that will not strip the tan.
