Signs & claims

Signs of skin pores

Cosmetic product bottles prepared for testing

Pore size can vary from person to person and is influenced by factors such as genetics, age, and skin type. Some individuals have smaller pores, other larger or more noticeable pores.

The goal is to keep the pores clean, unclogged, and less noticeable, promoting overall skin health and a smoother complexion.

Skin biology

Skin pores

Visible pores on the skin surface

Skin pores are tiny openings called sebaceus pores on the surface of the skin that allow the release of sebum. Sebum helps keep the skin moisturized and forms a protective barrier against external factors.

Sebaceous pores are commonly found on the face, particularly in areas like the forehead, nose, and chin ("T-zone"), as well as on the upper back and chest.

The appearance of pore size can be affected by factors like excess oil production, skin elasticity, and accumulation of dead skin cells, which can make pores appear more prominent.

It is not possible to permanently shrink or close pores. Various skincare products can help improve the appearance of pores but cannot completely eliminate them.
