We create solutions designed for maximum effectiveness and minimum side effects.
At AST, we develop and manufacture our own products, including the most potent, active retinol product on the market — Green Cream. With Green Cream, we were the first company in the world to successfully stabilize retinol utilizing a patented delivery system created by our medical director in New Orleans — dermatologist Nia Terezakis, MD.
For nearly 20 years, we have continued to develop products that promote healthy skin from a scientific basis and help consumers maximize their skincare spend. And now — for the first time ever — our results-delivering products are available for direct purchase by individual consumers on this site.
We are confident that your purchase and consistent usage of any of our products will help improve your skincare conditions and help create healthy, vibrant skin. We are so confident that our products will work for you that we offer a 30 day no questions asked refund on any of our products. All that we ask is that if you are having a problem, that you contact us first to help you resolve your issue.
