What is it? A 60-minute body massage designed to invigorate lymphatic circulation and stimulate your immune system. What's the atmosphere like? L'Occitane Petit Spa is tiny, with four treatment rooms. It's decorated in the same style as the L'Occitane shops, in muted tones of brown and dark green with lots of wood and a terracotta-tile floor. The staff are amiable, and the muzak is actually relaxing rather than annoying. How was the treatment? If you're looking for rose petals, tinkling bells and so on, this isn't it - it's thorough, no-nonsense and professional. It's a detoxifying massage, so it involves firm, sweeping movements. Be prepared to have your armpits prodded - a strange sensation if you're not expecting it. The masseuse uses grape anti-water retention gel containing organic grape juice from Provence; red vine leaf and horse chestnut extracts to stimulate drainage; and cypress essential oil to invigorate. The gel is faintly perfumed but not cloying. What else? Herbal tea is served before the treatment, then tea and a biscuit afterwards. The spa has a no-tip policy, alleviating any awkwardness about how much to leave. What were the results? If, like me, you're not quite sure what you may gain from a detoxifying massage, it's almost impossible to say - just soft, delicious-smelling skin and a sense of invigoration. Was there anything you didn't like? The therapist gave no explanation about what was happening, and the session ended a little abruptly for me - with a tap on the head. How much and where is it? The treatment costs HK$700 at L'Occitane Petit Spa, 1/F, 22-24 Russell Street, Causeway Bay, tel: 2893 9718
