37 JCAD JOURNAL OF CLINICAL AND AESTHETIC DERMATOLOGY august 2017 • Volume 10 • number 8 T rejuvenation of aging hands is becoming increasingly important to physicians and their patients. While a variety of invasive treatments are available, topical products that improve manifestations of aging hands are needed. in this brief report, the encacy of a topical product containing urea, lipids, sodium copper chlorophyllin complex, antioxidants, and humectants was assessed in subjects with moderate-to-severe photodamage of the hands.

AUTHOR CORRESPONDENCE: Vincent Gotz, Ms pharm, TradiTionally, Topical skin rejuvenating treatments have focused on the face, while other visible parts of the body have largely been neglected. More recently, the aging hand has become an area of increasing interest to aesthetic physicians and their patients. Hands, which are prominently visible to the individual and to those with whom the individual interacts, are important in human interactions and nonverbal communications. 1–3 Hand appearance has been shown to impact perceived age. 4 as such, individuals are becoming increasingly cognizant of the appearance of their hands. The dorsal parts of the hand are most adversely affected by exposure to ultraviolet (UV) radiation. With aging, dermal collagen, elastin, and glycosaminoglycans are altered, resulting in skin laxity and thinning. Epidermal thinning along with atrophy of subcutaneous fat causes veins, underlying tendons, and bony structures to become more visible in aged skin. additional clinical manifestations of the aging hand include textural roughness, dyschromia, lentigines, seborrheic and/or actinic keratosis, and wrinkling. 5–8 Traditional treatments to rejuvenate aged hands include lasers, intense light sources, chemical peels, sclerotherapy, dermal fillers/fat augmentation, and topical skin care products. 6–10 sodium copper chlorophyllin complex (cHlcu) has been shown to have several therapeutic properties in vitro, including antioxidant, anti- inflammatory, and antibacterial properties and inhibition of hyaluronidase. 1 1–15 in addition, topical application of very low concentrations of this active ingredient (0.025–0.1%) has been shown to have clinically beneficial effects on facial photodamage, redness, enlarged pores, and acne. 16–18 recently, in a human biopsy study, cHlcu demonstrated the ability to repair photodamaged skin by stimulation of biomarkers in the human extracellular matrix. 19 a topical formulation of liposomal cHlcu, urea, lipids, antioxidants, and humectants has been developed as a treatment to enhance skin texture, moisturize, and improve skin barrier function and signs of photodamaged skin. The product (rejuvaphyl® Hand and neck complex, Mdrejuvena, inc., carlsbad, california) was applied twice daily in eight subjects (aged 54–70 years) with moderate to severe photodamage of the hands to assess its ability to reduce signs of photoaging. Treatment was up to 14 weeks depending upon response. The only other product that was used on the hands was a sun protection factor (spF) 30 sunscreen. The cases in this brief report include both clinical evaluations and
