So you have sprayed the Skin Spray on your skin and it has a burning sensation – So this is what you need to do! You need to rinse out the straw of the bottle.
Start with pouring some water into a glass, then undo the top of the bottle, pulling the straw out completely, now put the straw into the glass of water and push down on the top so that the water is pulled through the straw – rinsing the straw.
The problem is that when you leave the bottle in the heat, then the moisture inside the straw evaporate leaving the concentration of H2O2 in the (water of the straw) stronger than what it should be.
Now replace the top of the bottle, give the bottle a shake, and all should be back to the way it is supposed to be.
