Cosmedix uses only the highest quality and most effective ingredients available today.  The percentage of active ingredients we use is among the highest available. Cosmedix was developed in an effort to increase the activity of ingredients while reducing any association irritation. This goal was accomplished through a purification process called “Chiral Correction.”

This system has been so effective even the FDA mandated that all new pharmaceuticals be Chirally Correct (if possible) before they are introduced to the public. Cosmedix is also dedicated to using the most natural effective products on the market today. The active ingredients act as preservatives for the products, therefore Cosmedix is an all natural line:  irritant free, preservative free, fragrance free, non acne forming, talc and dye free, Sodium Lauryl Sulfate free, and cruelty free. Cosmedix spends more on ingredients than any other product line in the skin care industry.


Chirality is defined as the “spin” of every molecule and cell receptor has naturally. Every molecule found in nature is chiral, meaning it spins either to the left or to the right.  Chirality has been described as a “geometric phenomenon” that occurs when two figures are identical in every way, with the exception that they are a mirror images of each other.

Not every molecule is chirally correct –  meaning its spin does not fit that of a cell receptor. Receptor sites are found on all cell membranes. Thousands of receptors coat each cell and wait for the molecule that will fit the lock – similar to three-dimensional lock on the door to our home. When the right molecular “key” fits into the receptor “lock” it instigates a biological response in the cell.

The skin is the largest organ of the body, containing millions of chiral receptors that dictate instructions to the cells when a molecule is attached. This process is one of extreme precision. Applying the wrong chiral twin to the skin often results in either a poor response, skin irritation or is simply not effective.

An ingredient attaching to a cell receptor is analogous to a hand in a glove. Just as the glove intended for the right hand doesn’t fit correctly of the left hand, when ingredients reach skin receptors with the wrong spin, the message can be blocked, incomplete or inaccurate. For example, Vitamin C is 50% left handed (l-ascorbic acid) and 50% right handed (D-ascorbic acid). Research has shown that only the L-version is an effective antioxidant (and thus is chirally correct). The other half of this product is not chirally correct is ineffective and can be often irritating to the skin.
