Why do many skin care products not have tin foil seals?

This is because different skin care product manufacturers do not necessarily have to use tin foil to seal them. Tin foil is a film-like metallic paper that looks like silver, mostly silver-white in color. It is actually aluminum foil, a thin sheet with a thickness of less than 0.2 mm that is processed by an aluminum foil rolling mill. It is mainly used in the kitchen for cooking, holding food, or making some materials that can be easily cleaned. Millions of tons of aluminum foil are used around the world to protect and package food, cosmetics and chemicals. Most aluminum foils have a glossy finish on one side and a matte finish on the other. Aluminum foil for food can be used on both sides to wrap food, and it is usually recommended to wrap it with the shiny side to improve heat conduction.

This is mainly because you don't have to worry about leakage during transportation if you turn the product upside down. However, for other products, it is normal not to have seals due to different usage methods and the hardness of the packaging material. Many of them are equipped with inner stoppers, or vacuum bottles, or the bottle caps have stoppers themselves. Generally speaking, when most merchants make seals, they consider the transportation method rather than the customer's use.

You can buy a small amount of affordable skin care products from a stranger purchasing agent. As long as they are reliable three times, there will basically be no problem.
