Acne is commonly known as “pimples”, also known as “acne”, “acne”, “acne”, etc. It usually occurs on It usually occurs on the face, neck, chest and back, shoulders and upper arms. It is a chronic inflammatory lesion of the hair follicles and sebaceous glands related to sebum metabolism, and is commonly referred to as “acne” because it occurs during puberty. The onset of acne is related to the metabolism of sebum. As long as there is life, there will be sebum metabolism, so there will be the possibility of acne. High prevalence during pubertal development. The causes of acne are very complex, mainly due to the increased secretion of sebum by the sebaceous glands, which blocks the hair follicles, and the proliferation of Propionibacterium acnes. The reason for the higher incidence of acne during puberty is because of the high secretion of androgens during puberty, or the increased responsiveness of androgen receptors. Other causes include medications, cosmetics, and the environment. First of all, we should recognize several misconceptions about acne treatment: Misconception 1: It is believed that after puberty, it will naturally get better, so don’t worry about it. This is a very wrong view. Statistics show that only 12% of acne patients can heal themselves. Delaying treatment will worsen the condition and make future treatment difficult, and may even leave unsightly scars on the skin. The second misconception is that you can’t stop squeezing your pimples with your hands, thinking you’ll be fine afterwards. The bacteria on your hands can easily make the inflammation deepen, making small pimples become big bags, aggravating the condition and increasing the degree of damage to the skin, leaving unsightly pigmentation and scars. Myth 3: Washing your face more every day will remove oil and dirt. The number of times you wash your face will make your skin more oily and your pores thicker. Washing your face twice a day with warm water can help to secrete sebum out of your body. Misconception four: diet is not disciplined, like to eat spicy and stimulating food, drinking and smoking, eating high sugar and high fat food such as eating chicken, duck and fish; do not like to eat vegetables and fruits, drink less water, poor excretion. The actual fact is that you will be able to control your acne effectively by adjusting your habits and diet, which is beneficial to the treatment of acne. So what to do when you have acne? The first thing we need to do is to prepare for a long-term “war”, the cause of acne is quite complex, the treatment also requires long-term persistence, we can not have the mentality of a quick fix, but should pay great attention to the regular dermatological hospital for diagnosis and treatment, do not rush to the beauty salon or listen to the advertisements. At present, the treatment of acne is more effective acne removal + herbal drug mask + LED red and blue light, etc.. Red and blue light therapy uses red and blue light to produce a photochemical reaction on living organisms, thus killing the culprit of acne – Propionibacterium acnes. Research has found that red light irradiation also has the effect of promoting collagen production, enhancing the repair function of the skin. Blue light alone is mainly used to treat mild to moderate acne. Blue light combined with red light has both antibacterial and anti-inflammatory effects, and is more effective than blue light alone for mild to moderate acne. For moderate to severe acne and larger cysts, we can also treat them with red light + ALA photodynamic therapy. ALA is a photosensitizer, and this method involves applying ALA to the cyst and sealing it locally for 1 to 4 hours and then irradiating it with red light, which produces a stronger photochemical reaction under red light and has a stronger effect on killing Propionibacterium acnes. There are many patients who come to the hospital with acne that has subsided, but due to long-term repeated squeezing and infection, their faces are full of pockmarked scars. This situation can be treated with fractional laser, which has a more positive effect on post-acne scars. Fractional laser technology is the newest and hottest technology in the United States in recent years, and is also the most popular skin cosmetic technology in the global skin industry, which is a minimally invasive treatment between invasive and non-invasive. The fractional laser is a minimally invasive treatment between invasive and non-invasive. The fractional laser is applied to the skin with small, evenly spaced holes, causing a series of biochemical skin reactions to tighten and rejuvenate the skin and remove discoloration. Since the fractional laser treatment will only cover part of the skin tissue, the new holes will not overlap each other and the normal skin between the holes is preserved, which acts as a bridge and facilitates rapid skin recovery. Patients can return to normal life after four to five days. The treatment itself is safe, and can treat any part of the body. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things, but you should go to a regular skin hospital or a dermatologist in a general hospital to get treatment.
