Acne pits are a common complication of acne. Acne pits often combine with or lead to enlarged pores, which in turn may cause acne growth and subsequent formation of acne pits. The treatment of both is similar, but the difference in the severity of the condition leads to a difference in the number of treatments, and the number of treatments for acne pits is more than that for simple enlarged pores. Large facial pores are a problem that 60% to 80% of women over the age of 25 or so experience. In the past, we would narrowly think that the pore problem is caused by oily skin with high oil secretion, but it has been proven that large pores are caused by multiple reasons, the main one being skin cell aging, causing skin aging and sagging, dryness and dehydration and slow metabolism of the stratum corneum. So where is the root cause of enlarged facial pores? Let’s explore the nature of skin pore problems. The root cause of enlarged pores and classification Keratin hypertrophy type – common in oily skin. The old keratin is not cleaned thoroughly, and too much oil clogs the pores; UV rays or climate influence slow down the metabolism, old keratin cannot be shed naturally, and the basal layer stops making new cells, resulting in epidermal hypertrophy and thickening of the stratum corneum. Aging and sagging type – a normal phenomenon of aging skin, especially noticeable in the cheek area, is called Y-shaped pores. However, it can also occur on young skin, and can cause premature aging if the skin is exposed to ultraviolet rays after spending long hours in a cool room, or if the skin is too dry or does not have enough sun protection. Acne – The result of clogged sebaceous glands, often in the T-zone and chin area. The sebum gland becomes clogged due to excessive sebum secretion or the accumulation of old keratin, making it impossible to remove sebum. Pigmentation type – shadows appear on both sides of the nose as dark dots, which are actually visually caused by the darkening of the pores. The pore structure itself is a groove, and the pores on both sides of the nose are slightly larger than the other parts, so when the light shines, the pores appear dark and large because they do not reflect the light source. Sebaceous type – Oily skin is more likely to appear. The nose, front and back are the areas with the most sebaceous glands in the body and are the most common, and are affected to varying degrees by skin type, age (most likely to appear between 15 and 30 years old), temperature (more severe in summer than winter) and humidity. The dangers of enlarged pores ①A significant proportion of adults have inflammatory enlarged pores, often accompanied by seborrheic dermatitis and redness of the skin on both cheeks and around the mouth, especially on both sides of the nose. Inflammation caused by general infection causes the skin blood vessels to dilate, and serum exudation causes edema to occur between the tissues, squeezing the subcutaneous tissue to bulge outside the epidermis, forming orange peel-like changes; ② excessive sebum secretion from the pores, blocked by dirt, prone to septic bacteria, inflammation of hair follicles, acne, pimples, blisters grow more and more, over squeezing, hurting the epidermis and dermis, easy to leave bumpy scars; ③ the normal skin lines of people are beige. “When the skin lines become heavy and sunken, they become one with the sunken pores. And because of the decline in elasticity, the skin sags under the effect of gravity, forming a certain direction lines, pores are connected one by one through the skin, forming part of the wrinkles. The solution for acne pits and enlarged pores For early and slight enlarged pores, you can try ipl intense pulsed light treatment. Intense pulsed light, also known as photorejuvenation, or photon for short, can act directly on sebaceous glands to inhibit excessive secretion of oil, kill acne bacilli and reduce inflammation of the skin; promote normal keratinization of the epithelium and improve the phenomenon of clogged pores. At the same time, some medicinal skin care products can also be used for joint treatment, and focus on cleaning, oil control and moisturizing, which can solve the root cause of young people with large facial pores. And acne pits, moderate and heavy pore size, the traditional is to use fractional laser treatment, but the effect is relatively slow, now the new technology is fractional radio frequency treatment (private hospital advertising is generally called what 5D or 3D gold fractional radio frequency, or water drop type fractional). The laser or radiofrequency emitted by the fractional method can reach deep into the dermis, stimulating fibroblasts and promoting the synthesis of new collagen, elastic fibers and hyaluronic acid, making the dermis more full and firm, and the pores and wrinkles will disappear naturally. The traditional fractional laser is divided into two types: exfoliative and non-exfoliative, mainly co2 laser or er laser, and non-exfoliative mainly 1320, 1440, 1520 laser. The non-ablative laser is mainly 1320,1440,1520. The ablative effect is fast, but there are many side effects. Non-ablative is safe, but the effect is too slow. The new fractional RF, which uses RF waves instead of laser light waves, has the advantages of both exfoliative and non-exfoliative lasers, and the effect is close to exfoliative laser, but has the safety of non-exfoliative laser, so it is more fashionable now. However, our latest experience now is to focus on fractional radio frequency, and at the same time, according to the actual situation of each person’s condition, appropriate with the exfoliating or non-exfoliating fractional laser, or also some purely fractional radio frequency, but at the same time to two to three times of coverage to treat. In short, radio frequency is the main, laser as a supplement, comprehensive treatment, the right medicine, in order to achieve the best treatment effect. Of course, at the same time, you can also still choose some medicinal skin care products combined treatment, and focus on cleaning, oil control, moisturizing.
