What is the difference between bleeding into the skin and redness of the skin?

Bleeding into the skin may look like a reddish patch of skin. But if you have bleeding into the skin, the area won’t become lighter (blanch) when you apply pressure. In contrast, erythema, a type of skin rash causing redness, becomes paler when you press on the affected area.
