A corrected version of this article follows as we have been informed by a representative for Osmosis that the Catalyst may help stimulate the growth of eyelashes; however, it was not designed for application to eyelashes and is not advertised as a product for eyelash growth.

Osmosis, makers of Replenish (a serum that was one of Truth In Aging's best products of 2009), has just launched an antiaging face serum called Catalyst.

At $160 against Replenish's $38, Catalyst doesn't fall into the keen as mustard price category. Still if it does all it is cracked up to do.... which supposedly includes capillary repair, pigmentation reduction, wrinkle smoothing, sun protection and, last but not least, eyelash growth (though Osmosis does not advertise this benefit).

As always with Osmosis, the ingredients list is mercifully short. The main ingredient is calcium ascorbate. A salt of ascorbic acid, it plays an essential nutrient that plays a pivotal role in the body’s collagen production, tissue repair, synthesis of neurotransmitters and resistance to infection. This ingredient mainly functions as an antioxidant in cosmetic products. It has many anti-aging benefits including building collagen, defending the skin against free-radicals, healing inflammations, reducing the appearance of fine lines & wrinkles and lightening discoloration.

There are a handful of amino acids, including proline. This is an important amino acid that can typically be found in energy drinks. Obviously it works a bit different when applied to the skin. Here, D-proline helps strengthen the cell envelope and skin, and is involved in the body’s production of collagen and cartilage.

Catalyst's claims of sun protection could be met by glucosyl hesperidin. The flavonoid compounds in glucosyl hesperidin are known to provide antioxidant, UV absorbing, and radical scavenging benefits, and are also known to be effective in strengthening collagen structure. Its high solubility is also favorable for use in skin care products.

Eyelash growth may be prompted by keratinocyte growth factor (the main active in Skin Active's eyelash growth product). This is a protein in humans that is encoded by the FGF7 gene. Studies on mice suggest that this gene is responsible for hair development.

I haven't tried this yet, but it looks very tempting (despite the dash of potentially toxic phenoxyethanol).
