山崎 勁 4 If you are looking for something that will really heat up your skin and keep it hot after you stopped massaging it then this one is not your ideal purchase. Using this gel you will only feel warmth when touching your skin with your own hands (or somebody's hands). As soon as the connection disappears you won't feel anything on the skin.However, the texture of this gel is amazing! At first tough it looks difficult to spread over the skin but first you need to melt it between your palms and then apply - it will be smooth as nothing else on the market and it will stay smooth for an amazingly long time! Most other heating massage products absorbs by the skin too fast so I have to reapply them or use the massage oil over the heating product to keep massaging. This gel can be used I may guess for hours!
