Obagi Medical Products’ ELASTIderm Decolletage System Reduces Visible Signs of Aging on Chest and Neck

Obagi Medical Products, Inc. (Nasdaq:OMPI), a leader in topical aesthetic and therapeutic skin health systems, today announced positive study results at the Fall Clinical Dermatology Conference Meeting showing that use of its ELASTIderm(TM) Decolletage System is highly effective in improving photodamaged skin of the chest and neck, also known as decolletage. The skin care system showed significant improvements in as early as 2 weeks. The treatment was also well tolerated and provided patients with high levels of satisfaction.

“In recent years, it has become clear to me that many women are doing a much better job of protecting their faces from sun damage; however, they continue to neglect their neck and chest area. It is common to see a woman with mild photodamage of their face and a heavily pigmented, rough and wrinkled chest. The results of this study speak for themselves. The system is highly effective, with the most obvious improvements in mottled hyperpigmentation occurring early in treatment, which continued to improve over time, as did wrinkling,” said James Leyden, MD, Emeritus Professor, University of Pennsylvania Health Systems and KGL, Inc., and lead investigator.

ELASTIderm(TM) Decolletage System is the only topical system backed by data from a 24-week clinical study that is designed to treat hyperpigmentation, including age spots and freckles, while reducing the appearance of fine lines and wrinkles. The System works by helping to replenish elasticity and build collagen in the chest and neck area. It is based on the Company’s patented Penetrating Therapeutics(TM) technology that allows for greater penetration across the skin barrier to help stimulate elasticity and increase the overall resiliency of the skin.

“Skin around the neck and chest is often overlooked in the anti-aging treatment process and our system can assist skin care professionals in providing the total rejuvenating results their patients want,” said Steve Carlson, President and Chief Executive Officer of Obagi Medical Products. “We are proud that the ELASTIderm Decolletage System technology can provide patients such significant improvement in the reduction of fine lines and wrinkles, as well as effectively treating hyperpigmentation.”

Study Methodology

Study subjects had a decolletage area with at least moderate levels of photodamage and at least moderate levels of mottled hyperpigmentation, fine wrinkling, or coarse wrinkling. All subjects applied the ELASTIderm(TM) Decolletage System to their entire decolletage twice daily for 24 weeks.

Baseline assessments of the Investigator’s Overall Integrated Assessment of Photodamage, the primary endpoint of the study, showed that all patients had very severe to moderate photodamage at the start of the study. By week 12, 53% of patients had only minimal to mild photodamage, increasing to 69% at week 24.

At the start of the study, all patients had moderate to severe levels of hyperpigmentation associated with sun damage. By week 24, 79% of patients had minimal to no signs of hyperpigmentation.

In addition, prior to treatment, all patients had moderate to severe levels of fine wrinkling. By week 24, 100% of patients had only mild to minimal levels of fine wrinkling.

Overall, 95% of patients were “satisfied” or “very satisfied” with the overall improvement of their decolletage at week 24.
