Large pores are typically caused by genetics, oiliness and poor skin care habits. When excess dirt and oil is allowed to accumulate on the skin, it settles into the pores, making them look larger.
Although there is no way to change the size of your pores, there are steps you can take to make pores look smaller.
Contrary to popular belief and claims by some skin care manufacturers, pores do not open and close. For this to happen, pores would have to have sphyrxter muscles, circular muscles that maintain constriction of an orifice or natural body passage. A pore is simply a pathway that provides moisture to the skin by allowing sebum to travel freely through the opening of the pore and onto the skin.
Clogged pores and blackheads
When excess dirt and oil is allowed to accumulate in and around the pores they become clogged. This is especially common around the nose and other areas of the face where dirt and oil can become trapped. If not properly cleansed, the substance clogging the pores will eventually reach the surface of the skin. When this occurs, what was formerly a clogged pore now becomes a blackhead as a result of oxidation.
How to prevent large pores
Washing your face before bed and thoroughly removing makeup is a crucial element in preventing large pores and blackheads. In addition, it is important to use the appropriate cleanser for your specific skin type. For example, it is common for people with oily skin to over cleanse which can lead to stripping of natural oils on the barrier of the skin. As a result, excess oil is produced exacerbating the pre-existing issue of an oily complexion.
Exfoliation for prevention of large pores
Opt for a chemical exfoliation process instead of a physical (grainy) scrub which can be too abrasive and cause tiny tears and/or broken capillaries in the skin. Retinol, hydroxy or retinoic acids are all forms of chemical exfoliation that with regular use, can prevent the accumulation of dead skin cells on the surface of the skin. Chemical exfoliation is especially helpful for aging skin that has been negatively impacted by years of environment damage and sun exposure. When these issues are combined with decreased production of collagen, the skin loses its elasticity making pores more visible.
Large pores due to aging skin
According to a leading dermatologist and dermatologic surgeon in New York, Dr. Ellen Marmur, the breakdown of collagen and elastin fibers cause pores to become distended and more oval in shape. As the skin begins to lose its elasticity, pores appear larger due to lack of firmness and support from the skin surrounding the pore, making pores appear larger. In addition to the above, enlarged pore size due to the aging process can benefit from topical skin care products that contain antioxidants and cell communicating ingredients that stimulate collagen. The dermal filler, Sculptra, can also improve the appearance of enlarged pore size as it stimulates the natural production of collagen while also adding fullness to the face and ultimately, smoother, firmer skin.
