Facial pores are required to detoxify the body by removing dirt, sweat, and debris from the skin. Facial pore appearance can be improved by reducing its size. A facial pore becomes clogged due to the accumulation of the dirt and this increases the complication of acne, blackheads, and face dullness with aging.

Factors responsible for open pores
Facial pores are enlarged due to the following factors:

• Sun exposure – Skin exposed to sunlight without protection can cause pore enlargement.
• Genetics – Hereditary also contributes to pore enlargement.
• Cosmetics and certain facial scrubs –  A few cosmetics can reduce the elasticity of the face, leading to open facial pores.
• Age – Aging skin cells lose collagen and elastin, which stretches the skin and causes elongated pores.
• Excessive sweating – It can produce and accumulate dirt in the pores.
• Excessive oil secretion – Sebaceous gland produces more sebum causing pores enlargement.
• Hygiene – Ignorance of hygiene measures is one of the biggest reasons for enlarged pores. 
• Makeup – Continuous makeup application also leads to clogged pores.
• Hormonal changes – Hormone-level changes can trigger sebum overproduction, causing open pores.
