Acne scars are a common complication of acne. Acne scars often combine with or lead to enlarged pores, which in turn may cause acne growth and subsequent acne scars. The treatment for both is similar, it is only the difference in severity of the condition that leads to the difference in the number of treatments, with acne scars requiring more treatments than simply enlarged pores. Enlarged facial pores are a common problem for 60% to 80% of women over the age of 25. In the past, we would narrowly think that the pore problem is caused by oily skin oil secretion, but it has been proved that enlarged pores are caused by a variety of reasons, the most important of which is the aging of the skin cells, resulting in aging skin laxity, dryness and lack of water and slow metabolism of the stratum corneum. So where exactly are the root causes of enlarged facial pores? Let’s explore the nature of skin pore problems. The root cause of large pores and classification 1, keratin hypertrophy – common in oily skin. The old keratin cleaning is not complete, too much oil clogging pores; ultraviolet light or climate impact, so that the metabolism slows down, the old keratin can not naturally fall off, the basal layer to stop making new cells, resulting in epidermal hypertrophy, thickening of the stratum corneum. 2, aging flaccid type – the normal phenomenon of skin aging, especially obvious in the cheeks, known as Y-shaped pores. But also occurs in the young skin, if long stay in the cold room, skin is too dry or not enough sunscreen, by ultraviolet rays, etc., will make the skin premature aging. 3, acne type – the result of sebaceous gland clogging, often occurring in the T word area and chin. Excessive sebum secretion or old waste keratin accumulation, so that sebum gathering can not be eliminated to form a blockage. 4, pigmentation type – the sides of the nose appear shadow, for the black dots, in fact, this is visually caused by the darkening of the pores. The pore structure itself is a groove, the pores on both sides of the nose itself is slightly larger than other parts of the light irradiation, the pores because of the reflection of the light source, it will appear black and coarse. 5, sebaceous – oily skin is more likely to appear, the nose, chest and back is the body’s sebaceous glands distribution of the largest areas, the most common, and by the skin type, age (15 ~ 30 years old is most likely to appear), temperature (summer is more serious than the winter) and humidity to varying degrees. The danger of enlarged pores 1, a considerable portion of adults with enlarged pores is inflammatory, often accompanied by seborrheic dermatitis, redness of the cheeks and the skin around the mouth, especially on both sides of the nose. General infection caused by inflammation, so that the skin vasodilatation, serous exudation so that the tissue between the occurrence of edema, extrusion of subcutaneous tissue to the epidermis outside the bulge, the formation of cellulite-like changes; 2, excessive sebum secretion of the pores, by the dirt obstruction, easy to produce pus-filled bacteria, inflammation of the hair follicles, acne, acne, blisters more and more, excessive extrusion, injury to the epidermis and the dermis, easy to leave a concave and convex scars; 3, the person’s normal skin pattern is a m-word, “m”, “m-word”, “m-word”, “m”, “m”. The center of the “rice word” is the pores, when the skin lines become heavy, sunken, and sunken pores as a whole. And because of the decline in elasticity, the skin sagging under the effect of gravity, the formation of a certain direction lines, pores through the skin one by one connected to form part of the wrinkle. Solutions for Acne Scars and Enlarged Pores In the early stages of mild 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, inhibit excessive secretion of oil, kill acne bacilli, reduce inflammation of the skin; promote normal keratinization of the epithelium and improve the phenomenon of clogged pores. At the same time with some pharmaceutical skin care products combined treatment, and focus on cleaning, oil control, moisturizing, can be the root cause of the solution to young people with large facial pores. As for acne scars, moderate to severe enlarged pores, traditionally treated with fractional laser, now the new technology is fractional radiofrequency treatment. Fractional laser or radiofrequency can reach deep into the dermis, stimulate fibroblasts, and promote the synthesis of new collagen, elastic fibers and hyaluronic acid, so that the dermis is more plumped up and tightened, and the pores and wrinkles will disappear naturally. Traditional fractional laser is divided into peeling and non-peeling two kinds, peeling is mainly CO2 laser or er laser, non-peeling is mainly 1320, 1440, 1520 laser. The stripping effect is fast, but there are many side effects. Non-exfoliative safety, no pigmentation, but the effect is too slow. The new fractional radio frequency, using radio frequency wave instead of laser light wave, at the same time has the advantages of peeling and non-peeling two lasers, the effect is close to peeling laser, but also has the safety of non-peeling laser, so it is more fashionable now. But now the latest experience is to fractional radiofrequency as the main, at the same time according to the actual situation of each person’s condition, appropriate with the exfoliative or non-exfoliative fractional laser, or there are also purely fractional radiofrequency, but at the same time with two to three times the coverage to treatment. In short, radiofrequency is the main, laser as a supplement, comprehensive treatment, the right medicine, in order to achieve the best therapeutic effect. Of course, at the same time also still with some medicinal cosmetics skin care products joint treatment, and focus on cleaning, oil control, moisturizing.
