The Firm is serving as co-counsel, alongside Bredin Prat, to Blackstone in connection with its agreement to make a significant investment in Lazeo, the number one provider of aesthetic medicine services in France. The partnership will support Lazeo’s continued growth and help meaningfully scale its operations and ongoing expansion. The transaction is conditional on customary regulatory clearances.

Headquartered in Paris, Lazeo is a founder-led, family-owned provider of non-invasive aesthetic medicine services including laser hair removal, injectables, body contouring and medical-grade facials. Founded in 2010 by Dr. Bernard and Dimitri Sillam with a single location in Paris, Lazeo has grown to become the number one provider in France with 135 locations, five in Belgium and significant runway for further expansion in both existing and new markets. In 2023, Lazeo entered Germany with the acquisition of Munich-based Cleanskin.

The Simpson Thacher team includes Geoff Bailhache and Paul Foote (Corporate); and Étienne Renaudeau and Pauline Patat (Antitrust).
