Waxing never loosens the skin as the skin tightening is provided by Elastin and Collagen fibres and the wax has nothing to do with both of these. But every wax brand has their own protocol to be followed that how a particular body part to be waxed and these protocols must be followed by the technicians without fail. Normally there is pre waxing, Waxing and post waxing protocols for most of the wax brands and these protocols should be strictly followed otherwise there are strong chances that one can permanently damage the skin where the waxing is performed.
