How much of a burn are people getting from this after shaving? I've used it a few times since I received it last week and I'm finding it's giving me one hell of a sting, almost feels as if it's burning and my face goes pretty red after using it. Tends to settle down after about 10-15 mins and feels okay after that. It's not something I've experienced with other aftershaves, saying that the others I've only really used all contain menthol (Proraso, Aqua Velva) so are cooling.
