San Soleil is a unique self-tanning lotion that delivers an even, natural-looking tan without exposure to the sun’s harmful rays. Most self-tanning products use the tanning agent DHA (dihydroxy acetone), which when used alone can cause dryness and create an uneven, orange, unnatural-looking tan. Sans Soleil contains erythrulose, a unique DHA enhancer. The combination of DHA and erythrulose helps ensure a more even, streakless, longer lasting tan without increasing dryness.
