G.M. Collin was founded in France in 1957 by a dermatologist who pioneered the use of collagen pellicles and a renowned experienced aesthetician.

Over the years, the company has become known for using the latest technology to develop innovative skin care products. Since the early 1990s, G.M. Collin has been developed and manufactured by Dermo-Cosmetik Laboratories, a Montreal-based company that has adapted the products, enhancing its dermo-corrective capacity to suit the North American climate and way of life.


At G.M. Collin, we abide by the strictest manufacturing regulations - ones that comply with current pharmaceutical standards. All of our products are manufactured in accordance with the standards set by Health Canada and the FDA in the United States. A team of highly skilled scientists and professionals develop all our formulas internally, selecting only active ingredients that have been proven safe and effective, and using them in optimal doses for the aesthetic conditions they are to treat.  


At G.M. Collin, products are developed with one goal in mind: To offer high tech skin care solutions, which are deeply rooted in the brilliance of nature. Beauty reborn is about recapturing your true, natural radiance with the help of modern technology.

G.M. Collin products are derived from natural plant and marine extracts and are technologically developed to achieve visible results. While our laboratory uses the highest scientific standards, our philosophy of respect for the environment mandates that our products are not tested on animals. This balanced commitment to good science is the cornerstone of all our product development. While our ultimate goal is to offer the best skin care products on the market today, the true spirit of G.M. Collin is to help women and men look great while feeling good about how they achieved the results.
