I used to look at natural remedies with a grain of salt, but this product is incredible for preventing haematomas from forming. You need to apply it ASAP after whatever accident. The longer you leave it before you use it, the less well it works. Apply generously and frequently if you are anticipating a big goose egg. Value for money: depends on your luck; the prices on Amazon fluctuate so wildly. I buy it anyway because it works so well for me. Like any medication, different people may respond differently.
