I have used L 'Oré al Paris slimming and firming massage gel. It has a professional massage roller at one end, which can simulate a professional body shaping massage, massage the parts until they are thin, and then apply a dense slimming gel at the other end. Caffeine compounds contained in it can promote fat decomposition and tighten skin at the same time. Massage and firming can achieve twice the result with half the effort, which is excellent for people who want to achieve local fiber effect in a short time. I spent 220 yuan, so I can lose my hard-to-lose little belly in one month, which is very cost-effective. Thin arms should also belong to the category of local slimming, you can try it.
