Acne, also known as acne vulgaris, is a chronic inflammatory skin disease involving the sebaceous glands of hair follicles. It is more prevalent in young people aged 15-30, with slightly more males than females. Approximately 80-90% of adolescents suffer from acne to varying degrees, and the onset of individual patients can extend beyond the age of 30, as the onset of acne is also associated with genetics, immunity, use of drugs, cosmetics, dietary stimulation and endocrine disorders, such as drug acne, infantile acne, menstrual acne and cosmetic acne. There are many factors that produce acne, such as those related to androgens, increased sebum production, proliferation of Propionibacterium acnes, and abnormal keratinization of the sebaceous ducts of hair follicles. Generally speaking, the onset of acne is not obviously seasonal, but the hot summer weather, increased sweat and oil secretion from the skin, and inappropriate use of heavy sunscreens and cosmetics may cause acne to occur due to narrowing of the inner diameter of the sebaceous ducts, blockage of the openings, or inflammation of the follicle mouth. Most people feel that acne is not a disease and would not prefer to see a doctor. Many people have tried various methods to get rid of acne, but acne is getting worse. As a result, not only do they delay early treatment, but they also leave behind acne marks of varying degrees. If acne is not treated in a timely manner, it will have a negative impact on the patient’s body and mind, and will cause them to suffer from low self-esteem, lack of self-confidence, and affect normal social interaction, among other problems. The correct attitude is not to be blind, not to be impatient, and not to avoid medical treatment. 1, squeezing acne with your hands is not advisable. Many acne-prone people will have a certain degree of “compulsion to squeeze acne”, see acne can not help but to squeeze, sometimes even unconscious behavior. The most horrific of the “war on acne” techniques is to squeeze by hand, which can be life-threatening if the skin is lightly injured, scarred or pigmented. The hand squeeze can destroy the protective layer around the pus, and the bacteria will spread to the surrounding tissue, causing inflammation in a wider area. The most dangerous is the “danger triangle” of the face, the triangle formed by the line from the corners of the mouth to the root of the nose on both sides, this area is more prone to acne, and the facial veins are connected to the cranial cavernous sinuses through the network of blood vessels. If you squeeze it hard, you may press the bacteria in the pus of the acne into the blood vessels, and if it happens to enter the reflux of venous blood, it will flow into the venous sinus of the brain, which may lead to inflammation, that is, intracranial infection. So the acne must not be “reckless”, do not squeeze with your hands, scratch. 2, clear acne topical drugs to be used with caution. General acne skin care products are not clinically verified by dermatologists before they are marketed, and it is difficult to determine whether each brand of acne skin care products can effectively remove acne. In particular, do not use ointments and agents that contain steroid hormone ingredients, as this can aggravate acne and cause steroid hormonal acne. In addition, even if acne clearing skin care products have an adjunctive therapeutic effect on acne, they can only be applied to patients with mild acne or as an adjunctive treatment in conjunction with medication. You cannot blindly choose acne clearing skin care products as the first choice of treatment for acne, and professional treatment must be provided in a timely manner. To remind women who love beauty, when using cosmetics, especially acne skin care products, they should understand their skin type, the nature of cosmetics, ingredients, etc., so as not to get rid of acne without hurting their skin more. 3, contraceptive pills in addition to acne must be used under the guidance of a doctor. The main reason for this is that the body’s hormone imbalance is related to the birth control pill, which can regulate the body’s hormone level. If the skin lesions of some patients are closely related to the menstrual cycle, or if the hormone levels are abnormal, you can consider using birth control pills for treatment. However, maintaining the balance of hormone levels in the human body by taking birth control pills is a practice that disturbs the normal physiological laws of the human body. Moreover, birth control pill treatment has strict medication cycles and precautions, and is generally used only when the effect of conventional treatment is not obvious, and must be used only under the guidance of a doctor. 4, physical therapy is effective for most people. At present, the more rapid clinical treatment of acne methods are red and blue light therapy, photodynamic therapy, laser and other physical therapy. Red and blue light has an anti-inflammatory and antibacterial effect and is more efficient for mild to moderate acne. Photodynamic therapy can shrink sebaceous glands, kill Propionibacterium acnes, and anti-inflammatory, etc. It has the effect of preventing recurrence and is a better choice for treating moderate to severe acne. The after-effects of acne mainly include hyperpigmentation and scars. Hyperpigmentation can be removed using photorejuvenation, and scars can be reconstructed by fractional laser for skin reconstruction. Effective removal of acne and acne scars. Physical therapy is usually also needed with internal and external medication, internal and external conditioning. If you are allergic, you need to go through anti-allergy treatment before use. 5.
