The function and efficacy of Invincible Plaster is that it can help to relieve the pain of skin and bones and make the whole body more capable of repairing. When a child encounters bumps, bruises or burns, parents can put on a plaster, but they should avoid some strenuous exercise and keep soothing movements, so that the wound can heal better. Adults can also stick a paste every day when they encounter low back and leg pain or sore bones and muscles.
