You mastered the narrow streets of Twin Peaks on a Vespa before your last trip to Florence. So when you’re headed to Ka`anapali Beach or the white sands of Baja, you’ll also want to arrive prepared. Luckily, plenty of Bay Area businesses can help you at least look like a local when you land.

Forget UV beds and spray-on tans. Spa Radiance’s new Sun-Kissed Treatment in 60 Minutes starts with an exfoliating scrub of organic Blue Bottle coffee, brown sugar, and honey, which allows for even appli­cation of color.

Then a tanning-lotion massage perfectly bronzes all those spots you can’t reach yourself. 3011 Fillmore St., 415-346-6281, sparadiance.com

Avoid the fake bake on your face, too, with bronzers and blushes from Lydia Mondavi’s new makeup line, 29 Cosmetics.
