Formulations that transform

Science

The world-class biochemists at Rhonda Allison are in constant research to uncover the latest scientific advancements and next-generation ingredients, as well as new ways of using time-tested, proven ingredients. 

Chirality

Over 150 years ago, Louis Pasteur discovered that most organic molecules have two parts: a “left-handed” part and a “right-handed” part - mirror images of each other. Such molecules are called “chiral”, from the ancient Greek for “hand”. Knowing whether a molecule is right- or left-handed is important because each type of molecule behaves differently in chemical reactions. Since our skin is considered chiral, it responds best to chirally correct ingredients. Much of biology is predicated on the fact that amino acids such as Malic, Lactic, Mandelic, Ascorbic, and Arginine are “left-handed” using the (L) isomers. Sugar molecules, which make up many of the skin strengtheners, protectors, and hydrators such as Tocopherol, Beta Glucosamine, and Fructan, are “right-handed” using the (D) isomers. For ingredients to be effective, they must be isolated to work with the appropriate isomers in our skin, rather than inundate it with both forms, which can lead to unwanted side effects or few results. Ingredients used in Rhonda Allison peels that have chirally corrected molecules are denoted by an (L) for the left or a (D) for the right. With the absence of the mirrored side, the molecule is more readily absorbed and provides the natural essence of the ingredient.

Intelligent Ingredients 

Always looking to nature for inspiration, RA blends the best active natural ingredients with highly beneficial, scientifically developed compounds such as growth factors, peptides, super antioxidants, retinaldehyde, anti-glycation and plant stem cell technology to create a synergy of superior professional treatments and customized home care products.  We blend nature and science to deliver and transform the skin.  

The world-class biochemists at Rhonda Allison are in constant research to uncover the latest scientific advancements and next-generation ingredients, as well as new ways of using time-tested, proven ingredients. As a result, skincare professionals have access to “intelligent ingredients” like the patented mitochondria complex, oceanic ingredients, flower acids, encapsulated retinals, second-generation peptides, and AHAs, and organic stem cell technology, blending nature and science to deliver and transform the skin.
