What are the most effective treatments for acne?
Acne (acne) is a chronic skin disease occurring in the hair follicle sebaceous glands, mostly in the head and face, neck, chest, back and other parts of the rich sebaceous glands. According to the causes of acne can be divided into endogenous and exogenous two categories. What does the most effective treatment measure of acne have?
i. Pay attention to the regulation of digestive tract function, eat less animal fat, sweet food and stimulating food, avoid spicy (ginger \ pepper), tobacco and alcohol, beef, sheep and dog meat, cola, coffee, alcoholic beverages, seafood and shellfish, mango, supplements, eggs, chicken, pork can be eaten, intake of vitamin C content more vegetables, fruits (tomato, hawthorn, orange, kiwi, cherry, strawberry, cabbage) and white food, such as often eat white radish, lily, tremella, fish fillet, tofu, water bamboo, milk and other food is very beneficial to forehead acne.
ii. Relax the muscles of the face and give the skin time to repair itself. Have a regular life, prevent constipation, develop the habit of defecating every day. Get enough sleep, preferably between 10 p.m. and 2 a.m., to give your skin a full rest. Ensure that every day 8-10 hours of evening take, refuse to stay up late, acne treatment is very beneficial.
iii. The affected area should be washed with warm water containing sulfur or other lipid-removing and anti-inflammatory soap. Accurate method is to wash hands first before washing a face, with the lukewarm water of 2 or 3 degrees or so (or green tea water) pat the face wet, rub face lotion in the palm of the hand, as soon as possible with cold water. It's best not to wash directly with tap water, which contains chlorine bleaching powder and facial inflaming bacteria. Chlorine can irritate the skin and cause more acne, while bacteria in tap water can complicate matters. After washing the face, gently blot the water with a cotton paper towel without fragrance. To keep your hair clean, wash it twice a week at most. It is best not to hide it on your face. Do not use hairspray products to keep your hair in a fresh state. Pillowcase sheets should also be washed frequently.
iv. Do not pick or squeeze the acne with your hands. Be careful not to squeeze it, otherwise it may easily lead to infection or even dangerous. Grow in facial seat sore cannot be squeezed with the hand, lest bacterium enters blood-brain barrier, cause serious consequence. In addition, massage and sauna can worsen acne because they promote blood circulation, so it is best to reduce such activities.
v. Do not use grease cosmetics and corticosteroids. Do not casually apply ointment, do not use skin hydrogen pine, skin music cream, En skin cream and other steroid hormone topical ointment, otherwise it will cause steroid stimulated acne, also do not use bromine, iodine drugs, otherwise it will cause verrucous papules, proliferative acne.
vi. Explain to the patient that acne is a common phenomenon caused by endocrine changes during puberty, mainly due to changes in sex hormones. Treatment can alleviate skin lesions, but it is difficult to completely subside and can be periodically aggravated or alleviated with endocrine changes. Because ultraviolet ray also can make acne generation, and bask in the sun often contact sunshine can make sweat gland and sebaceous gland secrete active, block pore, accelerate inflammation, appropriate wears a cap.
vii. Internal therapy can take compound poxli elimination scar removal drugs.
viii. It is recommended that you take zinc gluconate orally or take a multivitamin at the same time. Drink plenty of water usually. Eat more vegetables. Do not eat monosodium glutamate chicken essence, because this will cause zinc exclusion increase. Because they may lead to increased zinc exclusion. A deficiency of zinc can lead to this disease. There is no specific treatment for this. The signs of acne usually go away on their own. It is recommended to take the pill, 100 Xiao Dan try.
ix. Many people study, work and live in a closed air-conditioned environment. The huge pressure, uncirculating air, and radiation from computers, printers and other electronic devices make our lungs lose a healthy "growth environment", and the phenomenon of forehead acne also falls in line with the trend. Moderate exercise can increase immune capacity, promote intestinal peristalsis, promote metabolism, blood circulation. Therefore, more outdoor exercise, enhance the immune ability of the skin.
Differences between tomato skin powder and tomato
Tomatoes are rich in lycopene.
Pink tomatoes contain a small amount of lycopene, but very little carotene.
The difference is mainly in appearance, pink tomatoes are more beautiful than tomatoes, appearance level is higher; In terms of nutritional value, the tomato is actually more dominant, it has more nutrients than the pink tomato.
i. Freeze drying method
In this method, tomato concentrate was frozen at low temperature and then dried by sublimation of water under high vacuum. The harvested tomatoes still keep them high quality.
The original structure without compromising its original shape and size. As a result, freeze-dried particles have a porous structure that retains the space formerly occupied by water without collapsing, thus facilitating rapid rehydration of the product. But this method consumes a lot of energy, and the freeze-drying equipment is very expensive, so the product cost is high.
ii. Expansion drying method
Puffing drying method Tomato concentrate was dried by puffing drying equipment. An absolute pressure of 2.6 mm Hg is usually required for dehydration, and the temperature of tomato concentrates is usually 60 to 70 ° C. The drying time is usually 90 minutes to 5 hours in order to achieve a 3% moisture content in the final product. Before removing the vacuum, the product should be cooled down to avoid collapse of the swelling structure of the product, because the resulting tomato powder is thermoplastic.
The structure of tomato powder prepared by this method was relatively hard, the volume was similar to that of concentrate, and the rehydration performance of the product was poor. In addition, the expansion must be carried out under vacuum condition, the cost is relatively high, which leads to the high price of the product.
iii. Spray drying method
Tomato concentrate should be homogenized before spray drying. The homogeneous pressure is generally 150~200 kg/cm2. Generally using tower wall with cooling jacket (double tower wall, can use air cooling drying indoor wall temperature) centrifugal or two-flow type spray dryer to dry; If the heating medium is pre-dehumidified dry air, then the air inlet temperature is generally 150~ 160℃, the air outlet temperature is 77~85℃, and the feed concentration is generally 20%~30%.
There are already several variants of spray drying equipment on the market that can be used to process fruit and vegetable powders. Some are the use of air as drying gas, the use of 75~95℃ medium inlet temperature drying, so as to improve the production speed; Others are the dehydration of the air as drying gas, at a lower inlet temperature (25-50℃) for drying. But all of these spray-drying machines used to dry tomatoes have very high towers, adding to the cost of setting up factories.
iv. Foam layer drying method
The key to this drying method is the formation of a stable foam in the tomato concentrate by the addition of foaming substances such as soy protein, globulin, fatty lipids, glycolipids, and monostearate lipids. The temperature of the gas in the pass-through dryer is about 93 ° C, the speed is about 100~130 m/s, and it is added in a countercurrent manner. The drying time depends on the characteristics of the product and the drying conditions used. Generally, the drying time is 15~18 minutes.
v. Drum drying method
The rotating speed of the drums is generally 3.5 revolutions per minute, the steam pressure is 3.5 kg/cm2, and the spacing between the drums is 0.2 mm. In order to make the water vapor produced when dry can be quickly taken away, it is necessary to pass through the air, the air flow and the rotation direction of the roller is opposite, that is, the reverse flow into; And control the air humidity in the material collection area to be 15%~20%. However, this drying method does not really achieve the purpose of drying tomato powder. Because the moisture content of the product is at least 7%, it needs to continue to be dried by air at 20℃ for more than 24 hours. Otherwise, the color, flavor, and nutritional value of products with moisture content of more than 7% will be severely degraded during storage.
