■Enlarged Pores | Excessive Sebum Production
It is often seen on the forehead and around the noseEnlarged pores are caused by excess sebum secretion....which results in. One of the factors that causes excessive sebum secretion is,Dryness caused by a lack of moisture deep within the skin(so-called “internal dryness”) is one example. When the skin lacks moisture, its texture becomes uneven and pores become more noticeable; to prevent further dryness, the skin tends to overproduce sebum, leading to a vicious cycle in which the pores become increasingly enlarged.
It is important to note that excessive sebum production can be caused not only by “inner dryness” but also by poor lifestyle habits and improper skincare practices, such as over-cleansing.
■ Darkened Pores | Oxidation of Comedones, Melanin Deposition, and Vellus Hair
The following three factors are primarily responsible for darkened pores.
- Oxidation of Blackheads
- Melanin Deposition
- Cross-Sections of Vellus Hair and Clogging
Blackheads, which are a mixture of sebum and dead skin cells, turn black when they come into contact with air and oxidize.Blackheads caused by clogged pores are characterized by a rough texture when touched.So, this is what’s known as a “strawberry nose.”
In addition, UV rays and friction can stimulate melanin production, leading to dark, ring-shaped pigmentation in some cases. Furthermore, vellus hair may make the pores appear dark.
■ Sagging Pores | Collagen Deficiency Due to Aging
Sagging pores are caused by aging and UV damage,A condition in which the skin has lost its firmness and the pores have widened into elongated oval or teardrop shapesThis is because sagging pores occur when the skin is pulled downward due to a combination of age-related decreases in collagen and elastin—which support the skin—and dryness.
This is a common pore problem primarily seen on the cheeks of people in their 30s and older. If the pores become less noticeable when you lift the skin with your fingers, it’s likely that you have sagging pores.
