Pore are tiny openings on the surface of the skin, mainly composed of hair follicles, sebaceous glands, hair and ducts. Their core function is to excrete sebum, sweat and sweat, helping regulate body temperature; It also serves as a physical barrier for the skin, protecting deep tissues from external damage. Pore can be opened or closed according to environmental changes (such as temperature and humidity) to control excretion and heat dissipation. Understanding the structure and function of pores is important for understanding skin physiology, Choosing appropriate skin care products and diagnosing certain skin problems is crucial.

Pores are an important part of the skin. They not only affect the skin's breathing and excretion functions, but are also closely related to the appearance of the skin. When the pores become thick, it will cause people trouble, especially when facing the camera or needing to be photographed. At the time, shrinking pores has become a beauty topic that many people pay attention to. How are pores formed? How can we effectively shrink pores? This article will provide you with a detailed analysis of the structure and function of pores from a scientific perspective, and introduce some practical methods to help you improve pore problems.

Pore, also known as hair follicle orifice, is the opening of hair follicles and sebaceous glands on the skin. Each pore is connected to a hair follicle. The interior of the hair follicle is divided into hair root and hair follicle wall. The main function of the pore is to secrete sebum. Sebum is the skin's natural protective membrane, which can keep the skin moist and elastic. When sebum secretion is excessive or skin metabolism is abnormal, the pores will become thick or even blocked, forming blackheads or acne.

The size of pores is mainly influenced by inheritance, hormone levels, age, environmental factors and living habits. The pores in the T area (forehead, nose, chin) are more obvious because the sebaceous glands in these areas are more densely distributed.

Why do pores become thick?

1. excessive sebum secretion: Sebaceous glands secrete too much oil, causing pores to become clogged and gradually expand.

2. 角质代谢缓慢: Old dead keratin accumulates around the pores, making the pores look more obvious.

3. UV damage: Long-term exposure to ultraviolet light will cause the skin to age and the pores to become larger.

4. Improper cleaning habits: Excessive cleaning or using irritating products can destroy the skin barrier and aggravate pore problems.

5. 荷尔蒙变化: Hormonal fluctuations, such as puberty, pregnancy or menopause, can affect the secretion of sebaceous glands and cause pore problems.

日常护理方法

1. mild cleaning
   Cleaning is the first step in pore care, but excessive cleaning will destroy the skin barrier and aggravate pore problems. It is recommended to choose a mild cleansing product and wash your face 2 times a day. Avoid using facial cleanser containing irritating ingredients. After cleaning, use a towel gently pat dry without wiping it hard.

2. 定期去角质
   Removing old dead keratin can prevent pores from clogging, but pay attention to the frequency and method. Sensitive skin can be exfoliated 1-2 times a week. Oily skin can be appropriately increased the frequency. You can choose mild chemical exfoliating products, such as products containing salicylic acid or fruit acid, and avoid using granular matte cream.

3. 使用收敛水
   astringent water contains alcohol or natural astringent ingredients, which can temporarily shrink pores and make the skin look smoother. However, it should be noted that astringent water can only have a temporary effect and cannot be relied on for a long time. It is recommended to use it after cleansing to avoid frequent use on sensitive skin.

Medical beauty means

If daily care cannot effectively improve pore problems, you can consider some medical aesthetic methods. Medical aesthetic methods usually have more significant effects, but they need to be carried out under the guidance of a professional doctor.

   Acid acid can dissolve keratin and promote skin renewal, thereby improving the problem of large pores. Acid acid skin resurfacing usually requires multiple treatments, and the effect gradually appears.

2. laser treatment
   Laser treatment can act on the tissue around the pores through heat energy to stimulate collagen regeneration, thereby tightening the pores. Common laser treatments include dot matrix laser and picosecond laser, which have significant effects, but have a long recovery period.

3. RF skin firming
   Radio frequency technology heats the deep tissue of the skin through high-frequency current, stimulating the contraction and regeneration of collagen, thereby achieving the effect of tightening the skin and shrinking pores. Radio frequency treatment is suitable for all skin types and has a short recovery period.

4. microneedle therapy
   Microneedles stimulate the skin through tiny needles, promote collagen production, and improve the problem of thick pores. Microneedle treatment can be combined with skin care products to enhance the effect.

Diet and living habits

In addition to external care, internal conditioning is also an important factor in improving pore problems.

   Intake more foods rich in vitamins A, C, and E, such as carrots, citrus, nuts, etc., will help skin health, reduce the intake of high-sugar and high-fat foods, and avoid hormonal imbalances.
