After the winter, the big oil fields no longer produce oil, and those who love acne no longer have acne, but instead dry and tight, and even peeling and red, what's going on? All this has to return to the ** barrier and the pathogenesis of acne.
Why does the title say: Terrific ** Barrier? What does the barrier do?
*The barrier is a natural protective barrier composed of stratum corneum and sebum film, which can resist the penetration of external stimuli such as physical, chemical, and microbial factors, prevent the loss of useful substances such as water and electrolytes, and ensure the best health.
*The barrier is also called "brick and concrete", the terminally differentiated glial cells constitute the so-called "brick frame", and the double-layer interstitial cell filling in the glial cells acts as "concrete", forming the so-called brick "wall structure". The brick wall structure is topped by a weakly acidic sebum film that forms a natural barrier.
Why is it said that there are fewer acne and more peeling in winter?
1. The secretion of oil has decreased.
Acne is pathogenesis caused by abnormal levels of male hormones, excessive oil secretion, hyperkeratinization and blockage of the hair follicle orifice, infection with microorganisms, and inflammatory responses.
Among them, sebum is the pathology of acne. But after winter, oil secretion decreases, ** is no longer as greasy as in summer, and there are fewer breakouts.
2. The barrier function is weakened.
Insufficient oil secretion and thin sebum film lead to the weakening of the barrier function, which is easy to lose water, and is easy to be stimulated by external substances and dry, tight, and peeling.
3. The barrier is damaged.
Loss of keratinocytes and loose keratinocytes cause damage to the ** barrier. The damaged barrier will increase the penetration of external irritants into the inside, thereby causing neurovascular hyperreflex and inflammatory response, resulting in redness, itching, burning, peeling, redness and other symptoms.
Note: Only a small number of friends have acne caused by poor cleaning, bad lifestyle Xi, and like makeup.
What should I pay attention to in winter skincare?
1. Proper cleaning**. In winter** the barrier is fragile and the sebum film is thin, it is recommended to wash your face with a mild cleanser, and it is not recommended to wash your face frequently with a cleanser with a lot of foam and strong cleansing power or overheated water.
2. Exfoliate properly. In winter**, dry peeling and narrowing of hair follicle ducts can easily cause hair follicle blockage and acne. In addition, those who are too dry** are also very prone to eczema.
3. Apply enough moisturizer or lotion. Try to choose ingredients containing glycerin, lactic acid, hyaluronic acid, etc., which is conducive to promoting water absorption and moisturizing of the epidermis and repairing the best barrier.
4. Keep warm and apply body lotion. After winter, some people's hands and feet are cold, dry and peeling, itchy and other problems. First of all, keep warm, you can exercise properly, soak your feet, promote blood circulation and enhance the body's immunity.
In general, in winter, pay attention to sun protection, do not stay up late, do not smoke and drink, pay attention to washing your face and the temperature is appropriate, and lock in water with moisturizing cream. Where possible, a humidifier can be used to maintain humidity in the air.
