- This tanning essential is a must-have for any regular tanner. It's suitable for all types of tan and helps to prolong your tan for up to 3 days longer with even fade leaving skin velvety soft and smooth. Step 1: Immediately before tanning, apply St.Tropez Tan Enhancing Body Moisturiser to any dry areas (elbows, knees, ankles, hand and feet) to protect the tan from clinging to these areas. Step 2: Then simply apply your St.Tropez Tan as instructed. Step 3: For best results, moisturize daily and exfoliate regularly.
