Spa My Blend Ritz Carlton
Spa My Blend by Clarins (The Ritz-Carlton's spa -- which received the lofty title of World's Best Hotel Spa from Travel + Leisure magazine in 2013) got a makeover from French beauty brand Clarins.
Rebranded as Spa My Blend, it offers an exclusive line of skin products that can be mixed and matched by the staff to create a custom experience. (Fun fact: There's only one other Spa My Blend -- in Paris.)
