Moisturizing is the foundation of skin care. The basic skin care products that are indispensable for moisturizing and hydrating such as lotions, lotions and essences, how in the end should I choose the real moisturizing products? The easiest way is to look at the active ingredients of the product. Common Cosmetic Ingredients series, common moisturizing ingredients, let's take a look.

1, glycerin, the scientific name of propanetriol, glycerin can be classified as a natural ingredient moisturizer, mild texture, not easy to cause skin allergies, etc.. But glycerin itself is only moisturizing and no skin care function, so it works well for young, healthy skin. If the skin needs multifaceted maintenance, then the maintenance products also need to contain other effective ingredients and glycerin with the use.
2, collagen, collagen on the skin care although important, but its due to the molecular large, directly applied when not accepted by the skin. The real improvement of the skin collagen content is the use of collagen boosters, such as vitamin C, vitamin B3, vitamin A.
3, hydrolyzed collagen, hydrolyzed collagen is the large molecule of collagen to hydrolyze the processing into a small molecular weight of protein. The hydrolyzed protein is not as good as other moisturizers in terms of pure moisturizing effect, but has a certain function of improving skin texture. When you are shopping, make sure that the collagen in the maintenance products is labeled "hydrolyzed collagen", which is the collagen that can be absorbed by the skin. The actual fact is that you can find a lot of people who are not able to get a good deal on this kind of things.
4, amino acids, amino acid moisturizing mechanism and other moisturizers are different, it does not have a strong water absorption, but the skin moisture has a regulatory role, because the moisture content in the stratum corneum is reduced, the amino acid content at the same time reduced, so the maintenance products in the addition of amino acids is necessary to maintain the normalization of keratin function, but amino acids do not belong to the "main moisturizing factor "The main factor is the fact that it is not the main moisturizing factor.
5, natural moisturizing factor, the main components of natural moisturizing factor are amino acids, sodium lactate, urea, etc.. In pure moisturizing effect is not as good as glycerin, but because of its good skin-friendly, can regulate the skin pH function and maintain the normal operation of the keratin, not only has a moisturizing function, but also a certain maintenance function, is also indispensable moisturizing ingredients.
Spring cucumber management technology
Cucumber is one of the most popular vegetables among people, rich in sugars, free amino acids, vitamins, and essential minerals like calcium, phosphorus, and iron. It also contains cucurbitacin, which has anti-cancer properties. In addition to being a great source of nutrition, cucumber helps with heat clearance, diuresis, detoxification, and can soothe sore throats and abdominal discomfort. On average, farmers can expect a yield of 5,000 to 8,000 kilograms per mu, with an income of around 3,000 yuan per mu.
The cultivation process of cucumber involves several key steps: selecting seedlings, preparing the soil, fertilizing, planting, setting up trellises, managing water and fertilizer, and controlling pests. Each stage plays a crucial role in ensuring a healthy and productive crop.
1. **Variety Selection**: For spring greenhouse cultivation, it's recommended to use varieties such as Jinchun 4, 5, Jinyou 4, 6, Tianjin Green 4, 6, Zhongnong 6, 8, or Xiangyuan 3, 1, Xiangchun 3, 4. For open field cultivation, choose varieties like Zhongnong 9, 12, 7, Jinchun 1, 2, Jinza 2, 4, or Xiangyuan 3, 1, Xiangchun 3, Chunyuan 4.
2. **Sowing Seedlings**: Open field planting typically begins from mid-March to late April, using electric or cold bed nurseries. Greenhouse seedlings are sown between mid-January and mid-February, using electric heating. The recommended seed rate is 150 grams per mu. Before sowing, seeds should be soaked in warm water for 15 minutes, then washed and dried. Germination usually takes 4–5 days at a soil temperature of about 28°C. It’s advisable to grow seedlings in a nursery, transplanting them when they have 1 leaf and 1 heart, spaced 10x10 cm apart. Maintain daytime temperatures between 18–28°C and nighttime temperatures above 12°C. Apply a 10% manure solution when the plant has 1 leaf and 1 heart, and spray a 0.1–0.2% potassium dihydrogen phosphate solution when it has 2 leaves and 1 heart. A 20% manure solution should follow. About 6–7 days before transplanting, harden off the seedlings to prepare them for the field.
3. **Soil Preparation and Fertilization**: Avoid continuous cropping and select land that is easy to access and has good irrigation and drainage. Before planting, apply 100 kg of lime per mu, mix it into the soil, and add 2,000–3,000 kg of well-rotted manure along with 60 kg of compound fertilizer. Spray a 600-fold dilution of insecticide to reduce disease risk. Cover the soil with plastic film to help warm it up.
4. **Planting**: Transplant seedlings in early to late April for ground cover and open field cultivation, while greenhouse cultivation should begin before mid-March. Plant approximately 3,500 seedlings per mu and water immediately after planting.
5. **Cultivation Management**:
(1) **Facility Adjustment**: In March, temperature fluctuations and occasional hail require careful attention to warmth and protection. Ensure proper watering to avoid freezing. By April, temperatures rise quickly, but cold snaps and hail may still occur. Ventilate early in the morning and close late in the afternoon to keep seedlings strong. Once local temperatures stabilize above 10°C, remove the protective cover.
(2) **Trellising**: Start trellising when vines reach 30 cm in length. Use stakes and guide the vines regularly. After setting up the structure, introduce the vines gradually, detaching them every 2–3 days. After a sunny afternoon, place horizontal bars to support climbing. To improve early fruit set, spray a 1:50 diluted solution of male flower extract or stem extract on the plants.
(3) **Fertilizer and Water Management**: Spring cucumbers grow rapidly and produce many fruits, so consistent watering and fertilization are essential. During the vegetative growth phase, apply three top-dressings with 20% manure solution. During harvest, apply a 3% fruit-enhancing fertilizer after each harvest. Foliar feeding with 0.2% potassium dihydrogen phosphate 1–2 times can help delay leaf aging.
(4) **Pest and Disease Control**: Before the fifth leaf stage, use 80% trichlorfon to prevent melon wilt. After transplanting, immerse the roots in a 600-fold solution of melon scorpion to prevent soil-borne diseases like blight. Spray wettable powder at a 400-fold concentration 3–4 times to control downy mildew effectively.
(5) **Harvesting**: Greenhouse-grown cucumbers are typically harvested from late April to early May, while those grown in open fields or under mulch are ready in mid-May. Initially, harvest every 2–3 days, then every 1–2 days during peak season.
