X-Tend contains Erythrulos, a moisturizing deep-tan enhancer, and is impregnated with a tan enhancing liquid to help extend the life of your tan. Tan towel will not discolor elbows, knees and joints and goes on easily with no streaking. Has a refreshing citrus scent but will not combat with perfume or cologne. The fragrance will dissipate within 5 minutes. Great for travel as there are no leaks or spills to worry about!
