BUTT summer beauty tip: Buttheads who find themselves in the Catalan region of Spain this summer might want to indulge in an effective (and inexpensive) facial at the wild naturist beach Waikiki. Also known as Cala Fonda, the discreet cove is tucked away in the Tamarit-Punta de la Móra nature reserve.

We have it on good authority that the clay from the cove’s amber cliffs, mixed with crystal-clear salt water, makes an excellent detoxifying mud mask. You could do your face or — since you’re probably nude already — your whole body. Remove those dead cells, and experience a brilliant tightening effect which would rival any pricey treatment used by the Giorgio Armanis of the world.
