Endocrine:
Clinically, after puberty, gonadal hormones increase and acne begins to appear. In addition, about one-third of female patients will have obvious acne deterioration before menstruation, which shows the relationship between endocrine and acne.
2. Bacteria:
Improper cosmetics and skin care products, or bad personal hygiene habits, can easily lead to a large number of acne bacilli in hair follicles, thus leading to acne.
3. Food:
According to the statistics of Dr. Lin Yuzhi, a special acne clinic of National Taiwan University, peanuts have the greatest relationship with acne deterioration, followed by fried food, spicy food and chocolate.
4. Life stress and sleep:
Research reports show that stress, tension and lack of sleep will aggravate acne, so regular work and rest with the physiological clock and proper exercise to relieve stress are also small steps to maintain good skin. Therefore, "beauty sleep" is a virtue for the acne family!
Understand the causes of acne, but how to maintain it when acne is still inevitable? Dr Lin Yuzhi said: Skin prone to acne can be simply divided into two types, oily skin and dry skin. According to different oil conditions, some suggestions for autumn and winter maintenance are put forward:
First, oily skin
Facing the glossy nose and cheeks, it is suggested to control the glossy, and not "perfume" to eliminate the glossy phenomenon.
1. Choose a suitable facial cleanser: use a facial cleanser special for oily skin and wash your face before getting up and before going to bed; Don't use moisturizing facial cleanser. When you wash it, you will not only feel unclean, but also leave too much oil in your pores. But don't use "super degreasing" alkaline soap (like laundry soap). Alkaline soap will wash your face too dry and tight, stimulate the secretion of sebaceous glands, and the oil will come back faster after washing your face.
2. Avoid astringent water: astringent water will stab your face and feel very tight. Such products usually contain alcohol, which may not only harm the skin, but also stimulate sebaceous glands to secrete more vigorously in the long run. Dermatologists suggest that when the facial luster is obvious, oil-absorbing facial tissue should be used.
3. Carefully choose moisturizing lotion: basically oily skin does not need moisturizing lotion; If you must use emulsion, dermatologists recommend non-oily emulsion containing moisturizing ingredients, such as fruit acid, or cream with glycerol and hyaluronic acid as the main moisturizing ingredients.
4. Sunscreen: The strength of the autumn tiger should not be underestimated. Excessive sun exposure will deepen the color of acne scars and aggravate the inflammation of acne. So apply sunscreen products at least once a day before going out. Remember to choose a refreshing or acne-specific sunscreen product with an SPF of at least 15.
5. Use oil control products together: At present, only elubiol, an oil control product, is available on the market, which is medically proven to effectively inhibit sebaceous gland secretion. Most oil-control masks or oil-control gels absorb oil shine through the capillary phenomenon of non-woven fabrics or small particles in products, and can cover up small flaws on the face. Although they can't really "control oil", when used together, they can also provide a refreshing appearance for oily skin for a certain period of time.
Second, mixed skin with dry oil inside and dry outside
Many acne patients, acne and oil are concentrated in the T-shaped part, but cheeks and eyes are easy to dry. This mixed skin needs more careful conditioning.
1. Choose a facial cleanser with neutral skin: this product is relatively gentle on cheeks, but it still has enough cleaning ability on forehead, nose and chin.
2. Use lotion with caution: Apply moisturizing lotion only where necessary. If you apply a thick emulsion on the T-shaped part, it will often make acne grow wildly.
3. Choose foundation carefully: use water-based or non-greasy foundation or liquid foundation.
4. Unnecessary things: It takes time and money to use two different lotions or facial cleansers for T-shaped parts and cheeks.
5. Sunscreen: People with acne with mixed skin should use SPF 15 sunscreen lotion at least once a day even in winter, and it is more appropriate to choose refreshing sunscreen or special sunscreen for acne. In addition, the dermatologist's little warning is that the sun protection factor is usually not enough to replace sunscreen.
In addition, doctors also appeal to the public that acne must also be treated by specialists. Many acne patients have the misconception that "western medicine has great side effects" on the orthodox therapy in dermatology, but they are cautious about the orthodox therapy, but dare to apply various unknown remedies to their faces. This not only can't guarantee the curative effect, but sometimes it will do great harm to your face because of incorrect dressing or method. If you seek professional assistance from a dermatologist at this time, you will often leave a permanent scar.
Generally speaking, the treatment of acne should pay attention to the following points:
1. Patience
Whether it is external medicine or internal medicine, the most taboo is "fishing for three days and drying the net for five days". Usually, patients with moderate or above need continuous oral medication for two to three months to enter the stable period. Therefore, we should patiently and confidently cooperate with dermatologists' prescriptions and suggestions to maximize the efficacy of drugs and avoid drug resistance.
2. External medicine should be changed in season.
Many drugs for external use can make the skin very dry, especially for patients with mixed skin. If they continue to use an acid for external use in autumn and winter, their cheeks will often peel off. So you should let the dermatologist plan the autumn and winter treatment according to your personal situation.
3. Adult female acne
The cause of acne is slightly different from adolescence. Dermatologists will carefully evaluate these female acne patients over the age of 25, understand their hormonal status, and supplement endocrine regulation therapy to completely overcome annoying acne.
4. Oral acid therapy
At present, some doctors need oral A acid treatment for patients with severe cystic acne with large facial lesions, and it takes about three months to six months to completely calm down the volcanic activity of the face.
5. Dermatization and scar removal
For the scars left by acne, it is necessary to take advantage of the cold weather in autumn and accept dermabrasion or scar plastic surgery. At present, laser dermabrasion or traditional dermabrasion used in dermatology needs a recovery period of about one week. In the cool climate of autumn and winter, the wound is not easily polluted by sweat and bacteria, and the beautiful face can be restored smoothly.
