If you’ve got sensitive skin that blister when you scratch it, try using ice cubes to numb the itch. Ice is also water and water is good for your skin. If you’ve got an itch chances are its only in the outer layer so instead of scratching away like a mad man simply rub the ice for a short period on the area and the itchy feeling soon fades. Works every time and its natural no need for anti-itch ointments.
