Acne scars are a common complication of acne. Acne scars often combine with or lead to enlarged pores, which in turn may also cause acne growth and subsequent formation of acne scars. The treatment for 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 scars is more than that for simple enlarged pores. Large facial pores are a problem that 60% to 80% of women over the age of about 25 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, dry and dehydrated 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 thoroughly cleaned, too much oil clogging the pores; ultraviolet light or climate influence, so that the metabolism slows down, old keratin can not be naturally shed, the basal layer to stop making new cells, resulting in epidermal hypertrophy, keratin layer thickening. 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. This is caused by excessive sebum production or the accumulation of old keratin, making it impossible to remove sebum and forming a blockage. 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. Sebum type – oily skin is more likely to appear, nose, front and back are the areas with the largest distribution of sebaceous glands in the body and are the most common, and are affected to different degrees by skin type, age (15~30 years old are the most likely to appear), temperature (more serious in summer than winter) and humidity. The hazards of enlarged pores 1. A significant portion of adults with enlarged pores are inflammatory, often accompanied by seborrheic dermatitis, redness of the skin on both cheeks and around the mouth, especially on both sides of the nose. Inflammation caused by general infection, so that the skin vascular expansion, serum exudation so that edema occurs between the tissues, squeeze the subcutaneous tissue to the epidermis outside the projection, the formation of orange peel-like changes; 2, excessive sebum secretion of pores, blocked by dirt, easy to produce septic bacteria, inflammation of hair follicles, acne, acne, facial blisters grow more and more, excessive squeezing, injury to the epidermis and dermis, easy to leave bumpy scars; 3, the normal skin lines of people is a beige type. “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 action 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 scars 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 the 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 with some medicinal-type skin care products combined treatment, and focus on cleaning, oil control, moisturizing, can solve the root cause of young people with large facial pores. And acne scars, moderate to heavy pore size, the traditional is to use fractional laser treatment, now the new technology is fractional radio frequency treatment (private hospital advertising is generally called gold micro-needle or called many other strange and bizarre name). The fractional laser or radiofrequency emitted can reach deep into the dermis to stimulate fibroblasts and promote the synthesis of new collagen, elastic fibers and hyaluronic acid, making the dermis more plump and firm, and pores and wrinkles will naturally disappear. 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. Non-ablative is mainly 1320, 1440, 1520 laser. The effect of ablative is fast, but there are many side effects. Non-ablative is safe, no pigmentation, 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, the latest experience now is that fractional RF is the main treatment, 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 with fractional RF, but at the same time with 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 also or with some medicinal skin care products joint treatment, and pay attention to cleanliness, oil control, moisturizing.
