Things a diva loves: endless solos, referring to herself in the third person, and the occasional (though well-deserved) tantrum. But even the shiniest dress in the garment bag is "eh" when you're sporting damaged skin and prickly patches of unwanted hair. Feel stage-worthy again with today's deal from L'Essentiel in Belmont: Spend $149 for six laser hair-removal treatments (a $1,125 value) -- or pay $99 for four laser hair-removal sessions (a $1,000 value). If it's your visage that needs primping, put up $49 for a 45-minute OmniLux Photofacial (regularly $150), which features use of a noninvasive light therapy that can help reduce the appearance of fine lines and improve skin tone and clarity. One satisfied client crooned, "I really noticed a difference with these treatments. I felt and looked younger." This spa's talented estheticians will leave you feeling so smooth with its Palomar IPL system, you'll be the one begging for an encore.
