I. What is acne? In our daily life, we often hear people mention “acne”, “pimples”, “acne”, “pimples” and other terms. “Some patients ask us, “Doctor, is this acne or pimple, and how do you diagnose acne?” The three concepts of “acne”, “acne”, and “pimples” are the same thing, and they all refer to acne. Acne is a medical term, and “acne” and “pimples” are not medical terms, but a common name. When a doctor makes a diagnosis, he or she must use the medical term “acne”, which means that he or she must write “acne” or “pimples”. “Acne” is a much smaller concept. It is a type of acne, a milder type of acne, and is the initial stage of development. “Some are white in color, some are skin-colored, and some appear to have “black dots”, also known as “blackheads “pimples. Second, what are the causes of acne? If you ask what are the causes of acne, it is actually the same as asking what are the causes of acne. To understand more thoroughly, it is quite possible to need to answer a few questions. The first question is: Why does acne occur in young people? The human body contains something called “hormones”, and both men and women have “androgens” in their bodies. In puberty, both male and female “androgens” start to become very strong. The high level of androgens can promote the secretion of sebaceous glands on the surface of the skin. Many people don’t necessarily know what “sebaceous glands” are, but we should be familiar with “oily skin”, no matter if it’s in the hair, face, back, or chest, we usually feel very “oily”. “During adolescence, androgens promote the secretion of sebaceous glands, which create very good conditions for acne to form. There is a type of bacteria called Propionibacterium acnes on the face and scalp where the sebaceous glands secrete a lot. When it reaches a certain number, it causes a series of processes such as inflammation of local hair follicles and sebaceous glands, and these abnormal manifestations are presented to you and me in the form of papules such as “bumps”, which is the process of acne formation. If it continues to develop, it becomes more severe, causing nodules, cysts, scarring, etc. Second question: Does acne only grow on the face? As we mentioned above, acne is related to the secretion of sebaceous glands, which means that acne is more likely to grow in places where sebaceous glands are in full bloom. In fact, the sebaceous glands secrete more places, in addition to the face and also the front chest, back, buttocks, scalp and other parts, these parts can grow “acne”, but the acne that grows in the “scalp”, we may tell you is “folliculitis”. “The third question: I’m in my forties. The third question: I’m in my forties, why do I still have pimples? The first thing you need to do is to get a good idea of what you’re doing. This is the “endocrine” that everyone mentions at every turn. “Endocrine” is actually a very broad and large concept, and it is not easy to understand it clearly, and it is not necessary as a patient. But you should know that after the endocrine disorder, the secretion of your facial sebaceous glands will also be implicated, so that your face, which has been calm for many years, will grow “small pimples”, so that you can experience a “second spring” in your life. After reading the above, I think you should have a general understanding of the formation of acne or pimples, of course, the formation of acne is a comprehensive and complex process, there are other factors involved, such as skin grinding, external use of cosmetics containing chlorine, bromine can also cause acne, and these processes interact with each other to form a variety of clinical acne, about these contents, interested friends The literature can be consulted for further study. Third, what are the treatments for acne? Acne is the primary stage of acne, a relatively light acne, and this stage of acne is relatively easy to treat. A simple treatment is to apply a topical retinoid cream or gel, such as adapalene. If you want to be quicker, you can first do a “needle clear”, which is to use acne needles to treat the whiteheads or blackheads a little, and then apply anti-inflammatory creams topically. However, this process is not recommended to be done privately. Why? First, you can’t do it with medical asepsis, and second, the wound after treatment needs to be managed, so if you just remove it and don’t follow up on it, it will easily get infected. Fourth, what is the treatment cycle for acne? Acne is usually treated with topical medication alone, such as topical adapalene, for about three weeks before the results appear. Therefore, some people who are anxious may give up. Is it possible to squeeze acne or not? There are too many women who love beauty and cannot tolerate unwanted guests on their faces, and if pimples grow today, they should not be allowed to grow tomorrow. Some friends may use a “needle” to poke it, some simply use their fingers to squeeze it. If you have ever squeezed a pimple, you may have the experience that “the place where you squeezed the pimple seems to be very hard and red, swollen and swollen”, so we do not recommend using two fingers to squeeze the pimple. If you have to deal with it, what would be the best way to do it? This is a prerequisite, because too many patients in our clinic always see too many acne pits and marks on their faces after treatment.
