For example, just like a bottle, hydrating is to pour water into the bottle, and moisturizing is to put a lid on the bottle to lock up the water and prevent it from leaking out.
Similarly, in skin care, we should replenish water before moisturizing. You can first replenish sufficient water to your skin with hydrating lotion, and then use moisturizing cream to consolidate the protective film of your skin, so that you can lock the water.
Differences in composition
Common hydrating ingredients:
There are mainly hyaluronic acid, polyols, collagen, natural moisturizing molecules, amino acids and so on.
For young skin, hydrating is more important than moisturizing!
Common moisturizing ingredients:
Include ceramide, various vegetable oils, mineral oil, synthetic fat, beeswax, etc. Most products that usually contain a lot of oil are moisturizing, such as lotions and creams.
When choosing products, you can also choose according to the changes of seasons. In summer, you can reduce the moisture content, and in winter, you should use products with high oil content.
Different needs of different skin types
Mixed oily skin: both moisturizing and refreshing
Too much oil comes out of the skin because the lipids connected between keratinocytes are destroyed, and the stratum corneum can't lock water, so the oil comes out abnormally, and the phenomenon that the oil is dry inside appears.
It is necessary to choose products that do not contain oil and are lighter in texture to strengthen and replenish skin moisture.
Dry skin: powerful for hydrating and moisturizing.
Dry skin not only needs a lot of hydration in the early stage, but also needs strong moisturizing in the follow-up, and at the same time, it needs proper oil for the skin.
Choose products with high hydrating and moisturizing ingredients, and the nutritious texture can build a protective film for the skin, effectively lock in moisture and continuously provide nourishing and repairing for the skin.
Sensitive skin: hydrating and soothing first
Sensitive muscles are most likely to have problems because of dryness, which will cause water shortage sensitivity. At this time, it is necessary to increase the work of hydrating and moisturizing.
Choose products that focus on simple demands, and avoid irritating formula products such as alcohol, A acid and salicylic acid.
In addition to daily care, we should also pay attention to the selection of products with high moisturizing degree, and also use spray to supplement water, which can not only play a good hydrating effect, but also relieve and calm sensitive skin.
Then after we understand the difference, we should understand the reason why the skin is short of water, because it is not just skin care products that can achieve the real "moisturizing" wow!
Causes of skin water shortage
1. Seasonal climate is dry-dry allergy
During the season change, the skin will not only be dry and peeling, but also be red, swollen and allergic.
2. The sebum membrane disappears
What is sebum membrane? ! It is the first and most critical layer of skin self-protection, because the damage of sebum membrane leads to easy evaporation of water and acne, and 80% of skin problems are caused by it.
3. The stratum corneum is damaged
In addition to the sebum membrane, the damage of the stratum corneum is also a major culprit leading to the dryness of our skin. Can what we usually call hydration really penetrate into the skin? ! That'll be the day! !
The place in our skin that needs hydration most is the stratum corneum, and the water absorption can only reach the stratum corneum. Therefore, when the stratum corneum is injured, it will cause the skin to become dry and sensitive.
Problems caused by skin water shortage
Lack of water in the skin will cause rough skin, dull skin, dry cutin, imbalance of water and oil, etc ................................................................................................................................................
Keratin drying
For the lack of water in the skin, the most obvious performance is that the skin is dry, tight and prone to peeling. Especially now in summer, although the weather is beautiful, it will make the skin drier!
When the skin is dry, it is easy to cause peeling. Many cute people wait until the skin is peeling before they realize that the skin is short of water. In fact, at this time, the skin is already in a state of serious water shortage, which leads to the dry cuticle of the face and the peeling of dead skin and dander.
Large pores
In addition to dry skin, lack of water can also lead to large pores, because dry skin keratin can not be metabolized normally, and hair follicles accumulate too much old waste keratin, which makes the skin rough and dry, thus blocking pores and causing skin problems with large pores.
Water-oil imbalance
When the secretion of sebaceous glands and sweat glands of the skin is moderate, and the skin is in a healthy and ideal state that is not greasy or dry, such skin pores are delicate, ruddy and smooth, and it is not easy to react sensitively to external stimuli.
It is what we call perfect neutral skin, and all the skin care work we do is to approach the state of neutral skin infinitely!
The rest are the manifestations of water-oil imbalance. Dry skin is prone to lose water, oily skin is exuberant in sebum secretion, and mixed skin is usually dry and oily.
