The Story behind Cysteamine

Cysteamine is a natural agent that reduces melanin in human skin. It reduces brown spots, reduces pigmented marks and produces a uniform and light skin complexion. Long established as very safe and potent, it was never applied to skin pigment correction – until Cysteamine Cream®. Discover the story behind.

Naturally present in human cells

Cysteamine is naturally present in human cells as well as in human milk. The cysteamine molecule acts as an intrinsic antioxidant and is known for its protective role against ionizing radiation. Cysteamine content is highest in human milk compared to most other food sources and can be called as the anti-oxidant of human milk.

In the 1960's, a group of researchers led by Dr. Chavin discovered the very potent pigment corrector abilities of cysteamine. These researchers found that an injection of cysteamine into the black goldfish skin turned that skin white. Later in 1968, other researchers led by Dr. Pathak and Dr. Bleehen confirmed the efficacy of topical cysteamine as a pigment corrector therapy.

The first and only topical solution with cysteamine

However, all efforts for making cysteamine into a topical cream for human use were fruitless due to its fast oxidation once in contact with the air. It would turn red, loose its pigment correction function, and produced a very unpleasant « skunk odour». This resulted in the abandonment of researches into cysteamine, despite its high pigment corrector efficacy and safety profiles.

Fifty years later, Scientis resumed researches into cysteamine in our laboratories and made a significant discovery: we developed a technology that stabilised cysteamine molecules and significantly reduced its odour in cream conditions. Cysteamine Cream® is the first and only pigment corrector containing cysteamine.

The research findings

"Considerable efficacy in the Hyperpigmentation concerns"

April 2013, the American Academy of Dermatology publishes results that set Cysteamine Cream® as the new standard for hyperpigmentation concerns. Since then, the PanAmerican Society for Pigment Cell Research, the European Academy of Dermatology and Venereology and the British Journal of Dermatology published results demonstrating the potent pigment correction of Cysteamine Cream® by significantly efficacy in decreasing melanin content in pigmented marks. Results are confirmed significant efficacy of Cysteamine Cream® both by investigator’s and users’ viewpoints.

The series of randomized, double-blind, placebo-controlled clinical trials were conducted by independent groups of researchers..
