"From a geographic viewpoint, we are maintaining solid growth in Western Europe," said Chief Executive Jean-Paul Agon. "As we had expected, the improvement in North America is gradual. And the very strong dynamism of the countries in the rest of the world is continuing, particularly in Eastern Europe."
Sales in Eastern Europe soared 29.9 percent on a like-for like basis in the third quarter, the company said, while they rose 4 percent in Western Europe and 4.3 percent in North America.
Over the full year, L'Oreal is targeting a 7 percent to 8 percent rise in annual like-for-like sales.
L'Oreal shares closed down 1.1 percent Wednesday at €91.44 (US$129.68), giving the company a market capitalization of around €57.13 billion (US$81.3 billion). The stock is up 20 percent since the start of the year partly due to strong earnings growth in the first half of the year.
