1. After tilting the box of skin care products at 45 degrees, firmly grasp the box of skin care products and tap the bottom of the box to open the lid. The principle is to apply an impact to the jar. The lid of the skin care product is stationary, but the lid part continues to move due to inertia. The direction is away from the lid, so there is looseness. 2. Look for a sharp object or a knife, open a hole in the lid, let out the air, the air pressure inside and outside the bottle is balanced, easy to open. 3. If the lid is too tight, or the lid is killed by the cosmetics, heat it with hot water for a while and the bottle mouth can be opened.
