Bluemercury, a chain of high-end beauty product stores founded in 1999 by fabulous couple Marla and Barry Beck, and under the wing of parent company, Macy’s, has opened in the former Bonsoir spot (Bonsoir is still in Linden Square, over at the old Ceri space). The inventory-rich shop has brought with it all the Bobbi Brown, Nars, La Mer, and any other luxury brand the beauty junkies of Wellesley can handle. The September 10 grand opening will include a deluxe sample goody bag to the first 100 customers, makeup and skin consultations, and more. But if you can’t wait until then, they will likely slip you a couple of samples if you stop in to say hi.
