BACKGROUND: The neck is one of the most common areas affected by the aging process. A novel two product combination system composed of a serum and cream with hyaluronic acid and multiple strong antioxidants were investigated to determine their efficacy and safety in neck rejuvenation. OBJECTIVE: The objective of this prospective, randomized, double-blind, placebo-controlled clinical trial was to assess the efficacy and safety of a novel serum containing fractionated hyaluronic acid, peptides, and antioxidants for photodamage of the neck. METHODS: This was an institutional review board (IRB)-approved, randomized, double blind, placebo-controlled clinical trial involving 31 healthy subjects with moderate-to-severe neck wrinkling corresponding to at least a Grade 2 in wrinkles and score of 4 in elastosis on the Fitzpatrick-Goldman Wrinkle Scale. Twenty subjects were randomized to receive the active cream and serum system, while 11 subjects were randomized to receive the vehicles alone in serum and cream format for a course of two months. RESULTS: Both active and placebo cream and serum showed improvement of wrinkles, laxity, pigmentation, erythema, dryness, and texture of the skin, and high patient satisfaction scores. Histology of one of the active serums and cream samples revealed improvement in the quality of papillary dermal collagen and increase in the number of elastic fibers in the upper dermis after treatment. CONCLUSION: Our prospective, randomized controlled trial showed that the novel serum and cream showed improvement in skin aging on the neck, was well-tolerated by patients, and had a high degree of patient satisfaction.
