Skincare brand Dr. Barbara Sturm is evaluating its deal options, in accordance with industry sources.

The brand, founded by Dr. Barbara Sturm, is working with investment bank RBC to think about its options, sources told WWD. Annual sales are said to be around 70 million euros.

A representative for Dr. Sturm and a spokesperson for RBC each didn’t reply to requests for comment.

In April, it was announced that Oprah Winfrey had invested an undisclosed amount within the skincare brand after being introduced to the products by dressmaker Stella McCartney.

Sturm, an aesthetics doctor with training in sports medicine, launched the Dr. Barbara Sturm Molecular Cosmetics collection on Net-a-porter in 2014. Two years later, she launched Darker Skin Tones by Dr. Barbara Sturm with actress Angela Bassett.

The lines at the moment are stocked in Sephora, Nordstrom, Amazon and more. Bestsellers include Enzyme Cleanser, $75; Hylauronic Serum, $110, and Face Cream, $75.

Recently the brand opened two latest spas in Recent York, one uptown on Madison Avenue and one downtown in SoHo. The treatment menu includes Super Anti-aging Facial, Exoso-metic Growth Factor Facial and the Non-surgical Facelift Facial.

On the time of the Oprah investment, Sturm said: “Oprah loving the products and coming into our business is a giant honor and testament to the brand and our anti-inflammatory, skin barrier-strengthening philosophy. It also gives us access to a wider audience to bring free science-backed skin education to everyone.”
