Our Company

Lavax, Inc. is an Illinois-based research, development, manufacturer and distributor of all-natural, environmentally-friendly personal health care products. We are a small, family-owned company, established nearly 14 years ago in Palatine, IL. Our goal is to utilize cutting edge science and technology to develop innovative health care products to improve human lives. To date, our research projects have won three grants from National Institutes of Health and two Grand Challenge Exploration Awards from Bill & Melinda Gates Foundation.

All of our all-natural products have been developed by our team of scientists. We test our products on ourselves; we wouldn't be selling them to the market if we weren't extremely satisfied with the results. All the formulas have been thoroughly tested and found to deliver immediate and powerful results, time after time.

Our Founder

Renjie Chang, M.D., M.S., Founder & President

Dr. Chang started the company in 1999, determined to apply the knowledge and skills she had learned from a long career in the field of Obstetrics and Gynecology and in the pharmaceutical industry. In the past three decades, she worked as an OB-GYN in the Peking Union Hospital in China, a faculty member of OB-GYN at University of Oklahoma Health Sciences Center, and a drug developer at the Abbott Laboratories in Chicago. She established Lavax, Inc. to develop an innovative vaginal microbicide for preventing sexually transmitted disease with grants from NIH and Gates Foundation. While developing the sophisticated drug, she invented the all-natural NeuEve suppository as a spin-off. This innovative technology has made conceptual breakthrough in women’s personal care: reversing vaginal atrophy without using hormone. A patent has filed to protect its composition of natural ingredients. Because this product is a cosmetic for personal care, not a drug, it can be marketed to benefit consumers much sooner.

Two Gates Foundation Grants won by Dr. Renjie Chang:

  1. Novel Method Protecting Infants from HIV in Breast Milk
  2. A Novel Female-Controlled Antiviral Contraceptive

  • Which formula is right for me?

    The right formula depends on age.
    NeuEve Silk is milder than NeuEve Silver, and is designed for women with severe dryness and atrophy.
    Tip: For women with advanced vaginal dryness, using Cream daily plus the Silk formula twice/week works well.
    If intercourse is very painful or not possible or atrophy is severe, start with Silk formula.
                  If intercourse is painful, or you have BV, start with the Silver formula.
