Acne is a chronic inflammatory disease of the skin hair follicle sebaceous glands, it has a more familiar name, acne, because it is more likely to occur in young people aged 15 to 25 years old, so it is named, with acne, papules, pustules, etc. as a clinical symptom, often accompanied by seborrhea, that is, what everyone often calls "oil skin". Most patients with acne have symptoms that naturally lessen or heal after puberty.
Why is "oil skin" more likely to grow acne?
Normal acne is called acne vulgaris, the cause of its occurrence is mainly related to androgen levels and increased sebum secretion, young men and women in adolescence will be due to physiological reasons, resulting in strong secretion of male hormones, and androgens will make the sebaceous glands produce more sebum, if the skin is not clean at this time, a large amount of sebum and skin metabolism shed epidermal tissue will block the pores together, resulting in acne attacks.
In addition, abnormal keratosis of cells around the hair follicle and excessive proliferation of Propionibacterium acnes are important factors in worsening acne. On the one hand, cell keratinization can lead to a smaller hair follicle opening, limited sebum discharge, and it is very easy to form pimples that are visible or invisible to the naked eye; on the other hand, excessive sebum secretion will make a colonized on the skin of Propionibacterium acnes overproliferate, stimulate the hair follicle and surrounding cells to produce an inflammatory response, so that the pimples become papules, pustules, and even nodules and abscesses, and Propionibacterium acnes will also promote skin keratinization. In this way, acne is really a vicious cycle of round after round.
In addition to acne vulgaris, there are several other uncommon types of acne clinically, such as polymeric acne, explosive acne, pharmaceutical acne, cosmetic acne and premenstrual acne, of which polymeric acne and explosive acne are two more serious conditions and more difficult to treat.
How do acne scars occur?
If acne is not treated in time, the inflammatory response will make the acne that has formed pustules continue to worsen, turning into nodules or cysts of different sizes and dark reds, which can be suppurated and form abscesses after a long time, and become sinus tracts and scars after rupture.
Treatment of acne depression scars?
Skin lesions tend to occur on the face, and the papules, cysts, and nodules of effectively treated acne gradually resolve, but 30% of patients will leave scars, which are even permanent and difficult to resolve on their own, with sunken scars being the most common.
Although these scars do not affect the normal function of the skin, but seriously affect the appearance of the patient and reduce the quality of life of the patient, is there a safe, effective and less invasive way to treat the sunken scars of acne?
Ultra-pulsed carbon dioxide fractional lasers are known as a minimally invasive treatment between intrinsically invasive and noninvasive. It has both the rapid and significant effects of invasive treatments and the advantages of small side effects and short recovery time of non-invasive treatments. The ambient pulsed carbon dioxide laser will make many specific micropores on the surface of the skin, while the surrounding skin is not affected in any way, does not destroy the integrity of the skin, speeds up the repair of dented scars, reduces the pain of patients, and reduces the occurrence of complications.
What are the precautions for ultra-pulsed CO2 laser treatment?
First, clean the face during treatment, disinfect the skin to eliminate contraindications.
2. After the end of treatment, use collagen to apply to the skin for external use, and topical antibiotic ointment to prevent infection.
Third, it is forbidden to tear off exudates and scabs and let them fall off naturally.
Fourth, pay attention to sun protection for at least three months.
5. Eat a light diet, fast spicy food, and do not allow smoking and drinking alcohol during treatment.
After ultra-pulsed carbon dioxide lattice laser treatment, there will be some temporary local skin reactions, which are also described here:
1. Transient erythema.
Second, local edema generally resolves spontaneously within 1 to 3 days.
Third, pigmentation after the inflammatory response takes about a few months to resolve on its own.
