In their daily battle against stress, the massage therapists at Trees Bodyworks have a secret weapon: texture. They often enhance their strokes and pressures with exfoliating grains of sugar that soften calluses or silky oils that heal dry and itchy skin on the scalp. The studio’s clients can choose from a list of modalities that include both of the classics—Swedish and deep-tissue massage—as well as a specialty trigger therapy that targets muscles sore from chronic tension and pulling on the triggers of oversized novelty water guns.
