Frequently Asked Questions


Who is RevitaLash® Cosmetics?

RevitaLash® Cosmetics was founded in 2006 by renowned Ophthalmologist Dr. Michael Brinkenhoff, who created our original eyelash conditioner out of a desire to help his wife Gayle feel beautiful during her courageous fight against breast cancer. The brand began with an iconic lash conditioner and we have since developed an entire range of products designed to enhance the natural beauty and inner spirit of all women. We were the first, and we continue to be, the leading lash and brow beauty enhancement product line, and we remain the ONLY brand of its kind developed by an Ophthalmologist.

What does RevitaLash® Cosmetics do to ensure its products are safe?

Safety, responsible formulation, and a premium consumer experience are at the forefront of our product development efforts.  We work with top chemists in the cosmetics industry to ensure excellence in formulation, and we guide responsible developmentby always using the best available ingredients which meet our highest standards for health and safety.  New RevitaLash Cosmetics products are reviewed by experts such as dermatologists and/or ophthalmologists and undergo rigorous testing by independent research laboratories to ensure their safety. Furthermore, products are tested via third party consumer research to guarantee the very best products that deliver an excellent consumer experience. We are unique in the beauty industry in that we take 2-4 years to bring a new product to market.  You can’t rush safety and excellence. RevitaLash Cosmetics product development is never fast beauty.

What testing does RevitaLash® Cosmetics do to ensure its products are safe?

RevitaLash Cosmetics products undergo rigorous safety tests that are then reviewed further by ophthalmologists and/or dermatologists. We go beyond the standard tests done by industry to determine safety for use on the skin and ensure that products used on the delicate eye area pose no physiological risks to the eye.  For example, our eyelash serums undergo the following tests before we introduce them to the market:

1. In-house product testing prior to final formulation

2. Ocular safety

3. Ocular sensitization testing

4. Skin sensitization testing

5. Stability testing

6. Preservative (antimicrobial) efficacy testing to multiple pharmacopoeia standards

7. External consumer product review/benchmarking for third party validation of product performance
