Do external skincare products have impact on internal health?

The answer is: no

External skincare products are designed to be applied to the skin and are not intended to be ingested or absorbed into the body. They work by interacting with the outermost layer of the skin, called the epidermis, to provide various benefits such as moisturizing, cleansing, and protecting the skin from environmental factors. Therefore, external skincare products generally do not have a direct impact on internal health, which refers to the overall well-being and functioning of the body's internal systems and organs.
