Lo Bosworth (“The Hills”) announces her participation in the 2010 NIVEA “Good-bye Cellulite, Hello Bikini! Challenge,” a four-week program that combines fitness, nutrition, style and skincare with NIVEA Good-bye Cellulite products, such as the new Good-bye Cellulite Fast Acting Serum and the advanced Good-bye Cellulite Gel-Cream, to help visibly reduce the appearance of cellulite and increase bikini confidence. Like most women, Bosworth, who already eats healthy and exercises regularly, wants to take the extra step to keep her skin looking smooth, just in time for summer.
