1. Liquid skincare products: Generally, the subway has a limit on the amount of liquid that can be carried. Skincare products that do not exceed 100ml can be carried, but specific regulations may vary depending on the city or subway company. It is recommended to check local subway regulations in advance.
2. Non liquid skin care products: solid or semi-solid skin care products such as face cream, eye cream, powder, lipstick, eyebrow pencil, eye black, etc. are generally not restricted and can be taken directly to the subway.
3. Special packaging or flammable and explosive skincare products: Many subway systems restrict or prohibit the carrying of skincare products packaged in pressure cans or containing flammable and explosive ingredients. It is best to avoid carrying such products on the subway to avoid safety issues.
