PLANTIFIQUE's jade tool earns its spot the old-fashioned way: a curved edge that tracks the jaw and submandibular line, real stone rather than dyed resin, and tens of thousands of owner reviews that skew strongly positive. Jade warms faster than steel, so you lose the long cold-hold, but for technique-led lymphatic work that's a fair trade. As with all gua sha, the sculpting is temporary depuffing, not permanent change — but as a daily ritual the rubric rewards it highly.
