There is some concern (as yet unproven) that there may be a risk if the spray is inhaled, so you should be careful to avoid the face. However, sprays are popular. It is essential that enough is applied – a single spray onto the skin will not provide adequate coverage. Spraying into the hand and then applying is the best option, though this perhaps defeats the point of the spray. Rather apply 3 or 4 “coats” each time to ensure adequate protection.
