Reducing the appearance of age spots is the claim of Switzerland-based Rahn’s new ingredient, Illumiscin.

The company will be launching the active at the upcoming in-cosmetics show in Paris and claims it inhibits both the pigments involved in the formation of age spots.

“Age spots appear due to the formation of the sun-induced skin pigment melanin and the ageing pigment Lipofuscin,”​ product manager for cosmetic actives, Barbara Obermayer, told CosmeticsDesign-Europe.com.

Inhibits both melanin and lipofuscin

Illumiscin can inhibit both of these pigments and is therefore a comprehensive way to treat age spots, Obermayer said.

The ingredient is made up of vitamin C, oleuropein – a polyphenol present in olive leaves, and Zinc PCA – the zinc salt of pyrrolidonic carboxylic acid.

Oleuropein prevents the formation of liposfuscin and the vitamin C inhibits melanogensis.

The Zinc PCA is included in the ingredient as PCA is a natural moisturising factor present in the skin and can help uptake of vitamin C by the skin cells, thereby improving the inhibitory effect, Obermayer explained.

Rahn claims that in vivo ​tests illustrate the ingredient’s ability to decrease the size of the age spots (by 21.2 per cent after 3 months) and evens out the edges (by 13.5 after 3 months).

In addition, the company says the ingredients is well tolerated by the skin and can be formulated into a range of cosmetic products designed for mature skin including hand creams and décolleté products.
