Do not let the care products you have just placed. Make sure that the products covered by the condition closely. If a product is not closed tightly after use, it will affect the quality of the product itself. Keep well out of direct sunlight or placed in very hot ambient temperatures. Make sure you follow directions on product packaging regarding the product placement.If you feel a period long enough to stop the use of the product, and one day want to use again, think twice. It is possible that the product is already not what it used to even have expired. We suggest you buy new products only, to avoid the things that are cool on your skin.
