Presentation to focus on importance of pH in the skin and skin-care products

(St. Louis, MO, March 18, 2010) – Dr. Lawrence Samuels, chief of dermatology at St. Luke’s Hospital in St. Louis, Missouri, and creator of the Rx Systems PF® skin and hair-care lines, has been invited to speak at the prestigious International Esthetics, Cosmetics & Spa Conference (IECSC) in Las Vegas, Nevada.

The IECSC Las Vegas event is scheduled for April 24 to 26 at the Las Vegas Convention Center. One of the premier spa events in the country, IECSC features exhibits from more than 600 leading skin-care, wellness and equipment companies; industry-leading conferences and manufacturer education classes.

Samuels’ presentation, “What’s Your pH IQ? The Importance of pH in the Field of Skin Care,” is scheduled for 9:30 to 10:45 a.m. on April 26 and will review the fundamentals of pH, explain what creates pH and why it is important, and describe how the pH of skin-care products affects the skin and product efficacy.

“pH is a highly misunderstood, yet very important aspect of skin care,” said Samuels. “pH is the ‘thermostat’ that regulates the skin and the effectiveness of cosmeceutical skin-care products. pH can dramatically alter the free acid concentrations of biologically important molecules and it plays a major role in regulating the aging process of the skin, while protecting it from environmental stresses.”

Samuels is a board-certified dermatologist with a thriving practice in St. Louis. He is also a fellow of the American Academy of Dermatology, in addition to being the head of dermatology at St. Luke’s Hospital. His other credentials include:

  • Instructor of internal medicine, Division of Dermatology, Washington University School of Medicine, St. Louis
  • Member of American Society of Cosmetic Dermatology and Aesthetic Surgery
  • Member of International Society for Hair Restoration Surgery
  • Member of American Society for Dermatologic Surgery
  • Member of American Society for MOHS Surgery
  • Member of American Society for Laser Medicine and Surgery
  • Widely published in medical journals and texts

Samuels established Rx Systems PF in 1996 after realizing the need for skin and hair-care products that were easy to use, affordable and effective. After witnessing positive results with regular use of glycolic acid skin-care products and medicated hair-care products, Samuels developed the Rx Systems PF line of skin care products-–a complete line of pH-balanced, glypoic complex (glycolic acid and alpha lipoic acid) based products, vitamin C serum in a trademarked age bloc delivery system, retinols, enzymes and moisturizers for the face and body. Originally distributed only in St. Louis, Rx Systems PF products are now sold at selected retailers nationwide and online at

Through intense scientific research and medical experience, Samuels has become an expert on pH and its effects on the skin, and he encourages other skin-care professionals to learn as much as they can about it by attending his presentation. Attendees will be tested on their basic knowledge of pH in the body, skin and skin-care products and have an opportunity to ask Samuels specific questions about pH. 

“The more a skin-care professional understands the complexities of pH, the more effectively he or she can address their patients’ specific skin-care concerns. The skin and body are a combination of alkaline and acidic reactions, keeping them in balance greatly impacts the skin and body’s ability to perform at its optimal levels,” said Samuels. 

Insults, such as the sun, tanning beds, pollutants, cigarette smoke, radiation, unhealthy foods, hormones, excessive washing and poor skin-care products, alter and damage the pH of the skin. Altered pH results in skin irritation, acne, skin infections and accelerated skin aging that is characterized by rough skin texture, large pores, poor skin tone, blotchy skin color and wrinkles. 

“All of the body’s regulatory systems, such as, skin cells, kidney cells and liver cells; and molecules, such as, antioxidants and enzymes, serve the purpose of balancing the pH of the skin and body,” said Samuels. “Thus, it is critical to focus on maintaining healthy skin, not waiting for damage to occur, and to be an active participant in the health of our skin and body.”
