ZURICH, July 9 (Reuters) - Swiss skin care company Galderma will begin trading in the country's SMIM mid-cap index from Sept. 23, replacing solar panel maker Meyer Burger, the SIX stock exchange said on Tuesday.

Galderma debuted in late March, pricing its initial public offering (IPO) at 53 francs per share. The stock has since risen by more than a third to 73 francs per share.

There are no changes planned to the blue-chip SMI index , the stock exchange said. (Reporting by Oliver Hirt; Editing by Emelia Sithole-Matarise)
