Use of cerave emulsion components
Cerrave's PM milk, in fact, its full name is: Cerrave night facial moisturizing lotion. This is a typical cosmeceutical. The manufacturer is Lang Wei North American Pharmaceutical Co., Ltd. Let's study the instructions on the package first.
Product name: facial night moisturizing lotion
Suitable for: normal skin and dry skin.
Efficacy: patented formula, repair the natural barrier of skin.
Do you see anything wrong? The function of the product is to repair skin barrier, but it is suitable for healthy neutral and dry skin. If my skin is healthy and normal, why should I repair it? For the problem skin, it needs to be repaired, such as sensitive muscles. . . But you didn't label it as sensitive skin. . . . You may question my nitpicking? Ha, for a pharmaceutical factory, the instructions printed on the package can't contradict each other, right? . . . Well, what about the moisturizing milk produced by the pharmaceutical factory? Let's take our time.
I. Component analysis
Stick the composition diagram on the package as follows:
There are 22 ingredients 1 * * marked on the packaging label. There are different lists here. I know you don't want to see this pile of chemical names. . . Because the package says that the product has moisturizing and repairing effects, let's take a look at these two ingredients.
1. moisturizing ingredients
Glycerol can absorb water, and moisturizing skin care products often use it to absorb water molecules in the air to keep the stratum corneum covered with glycerol moist. This characteristic of glycerol makes its moisturizing effect easily affected by the humidity in the air. In the low humidity season or environment, glycerol can't absorb enough water in the air, but will absorb the water in the dermis of the skin, making the skin drier and even dehydrated.
Polydimethylsiloxane (silicone oil) is completely different. Refreshing, colorless and tasteless, not afraid of light, heat and cold. Its chemical properties are very stable and it can breathe. After forming a breathable thin oil film on the skin surface, it can moisturize the skin. Triglyceride caprylic acid/capric acid is a very refreshing and tasteless oil, which is a derivative of palm oil or coconut oil. It is extracted by thermal fractionation. Because it is compatible with human skin, it has a non-greasy texture. Adding it into cream or emulsion can improve its ductility, and has the functions of lubricating and softening skin.
Cetearyl alcohol belongs to fatty alcohol, and its appearance is white wax, which can provide creamy texture. Commonly used as softener, emulsifier and thickener, it can be synthesized artificially or extracted from coconut fatty alcohol. This ingredient can help the product penetrate into the skin more easily, and can also be used as an emulsifier to make the product easier to apply. The FDA also allows cetearyl alcohol to be added to food, so it is safe.
Sodium hyaluronate, also known as hyaluronic acid, is an acidic mucopolysaccharide, which naturally exists in corneal skin and can absorb 1000 times its own weight! In order to keep skin moisture, prevent water loss through epidermis and repair the barrier when skin is damaged, the skin will not feel dry after use and increase luster. In short, it is the chemical with the strongest water storage capacity at present. These five are commonly used moisturizing ingredients. I won't go into details one by one.
2. Repair ingredients
Ceramide -3 is a lipid substance and a synthetic component. It is similar to the substance that constitutes the stratum corneum of the skin, and can quickly penetrate into the skin and combine with the moisture in the stratum corneum to form a network structure to lock the moisture. It has a good moisturizing and repairing effect on the skin, and is an important skin activating component in the stratum corneum, which can strengthen the skin barrier and rebuild cells. Irritated skin especially needs more ceramide. Studies have shown that friction products containing ceramide can reduce redness and skin moisture loss and enhance skin barrier.
Ceramide 6 II plays the role of skin conditioner, antioxidant and humectant in cosmetics. It can improve sebum membrane, inhibit active secretion of sebaceous glands, balance skin water and oil, and enhance skin self-protection function. It is more suitable for young skin with greasy skin and needs. This component has a good effect on skin moisturizing and repairing, and is an important skin activating component in the stratum corneum, which can strengthen the skin barrier and rebuild cells. Irritated skin especially needs more ceramide. Studies have shown that friction products containing ceramide can reduce redness and skin moisture loss and enhance skin barrier.
Ceramide 1 is used as skin conditioner and humectant in cosmetics. It can intensively repair the skin's natural sebum membrane, strengthen the defensive function of the skin surface barrier, have good sealing performance, reduce water evaporation and loss, and is suitable for all skin types.
The precursor of sphingosine phospholipid, similar to skin lipid, is an important part of water retention and barrier function. It is easily absorbed by human skin and hair, and can promote the penetration of other nutrients. The composition can be used as skin conditioner, humectant and antioxidant in cosmetics. Cholesterol can be used as softener, emulsifier and viscosity control agent, which can strengthen the moisturizing ability of skin. Adding cholesterol to cosmetics can maintain the normal function of skin, and it is also used as a stabilizer and humectant.
Comments: For the repair of stratum corneum, we should focus on it. As we know, the stratum corneum is a brick wall structure, bricks are keratinocytes, and cement mortar-structural lipid plays a connecting role in the middle. Ceramide and cholesterol are structural lipids.
Theoretically, when these structural lipid components are coated on the skin, they can penetrate into the stratum corneum at different depths and combine with the original lipid components, while * * * can strengthen the connection of keratinocytes, thus strengthening and repairing the skin barrier function. This is like: a wall that has been built, accidentally scraped by a car, and rubbed off some bricks and cement. Then you just need to put on some cement mortar to repair it.
However, skin is the structure of living organisms. When the skin is damaged, is it useful for us to simply apply these structural components to the skin surface? If we compare the process of skin growth to building blocks (here, we might as well regard basic nutrients such as sugar, amino acids, fat, vitamins and minerals as building blocks). Blood transports various nutrients to dermis, and then under the control of DNA, different structural units of skin are synthesized and combined to form skin.
Then, when building a building block, if the top layer of the building block is damaged for some reason, you can take it down and rebuild it with new building block materials. However, if the outermost layer of the stratum corneum is damaged, can you tear it off and reassemble it with these structural lipid components? Don't! Of course not!
So, in fact, how much influence can structural lipid components have on the surface energy of skin? In my opinion, these ingredients can enter the stratum corneum shallowly or deeply, which can play two roles. First of all, they can delay the evaporation of skin moisture; Secondly, it can strengthen the adhesion between some keratinocytes, thus slowing down the shedding of outer keratinocytes. In this way, with the metabolism of cells, the deep healthy cells keep moving up, and the damaged cells on the outer layer keep falling off, and finally the skin is self-renewing and repaired.
3. Nicotine
Nicotinamide is actually vitamin B3. Let's look at the claimed efficacy of nicotinamide:
1. Whitening: Nicotinamide can act on melanin, reduce its transfer to surface cells, accelerate skin metabolism, promote melanocyte shedding and improve skin quality.
2. Anti-aging: Nicotinamide can also greatly reduce or eliminate skin aging, such as wrinkles, peeling and large pores. Reduce the damage of free radicals to the skin, prevent aging, repair the skin and reduce facial dullness.
3. Oil control: External application of nicotinamide can reduce the production of fatty acids and triglycerides in sebum, thus reducing pores and reducing the severity of acne.
In the ingredient list, nicotinamide is a whitening ingredient promoted by Procter & Gamble, ranking fourth here. However, this product does not claim whitening effect. So, what role does nicotinamide play here? We look for answers from user feedback.
Two. User feedback
Ok, let's look at the user feedback.
It actually saves money to apply it every night, but I really feel a little white recently, and brush acid won't hurt or anything, so I bought it back.
I will use it after washing my face tonight. I patted the water first, and then used the emulsion. The tingling is strong, and it will be fine in a while. The emulsion is very delicate and light. This is my real sense of use, I hope to give you reference. I don't know if it's true or not. Never used it before. Weibo planted it this time.
The texture is a little curd-like, watery, light, super absorbent and highly plastic. After absorption, the skin is very soft, and the moisturizing effect is very good, and it is not oily or sticky. The next day, the skin was oily and shiny.
I am allergic. My face is itchy, red and peeling. I tried many ways, but it didn't work. I bought it and tried it. I arrived last night. Although it can't be done once, it does have an effect, better than sheep oil.
This milk has been used for several years, and the mixed oil skin is not greasy, so several layers are not greasy.
It's refreshing, not oily or greasy, and very comfortable.
I bought it for the second time. After using it, I almost never got pimples again.
I had an allergic reaction after using it for the first time, and then I felt itchy. I don't know if I should feel this way. I will add it after using it again. Things are good, but the texture is just right, but friends who buy this must know whether it is durable or not. My reaction is that this ingredient is not lasting, and some people can set up a useful preparation when using it. Give some time to see if they will set up a useful cigarette factory.
Unfortunately, I had an allergic reaction ... I stopped using it and my redness stopped. Feel sad, try it, it's good. Used to wipe the neck, may it turn white ~
Moisturizing is ok, not greasy, but the whitening effect makes people scream.
I like it very much. It will definitely be dry, not greasy at all, better than those big brands of lotions, and really not greasy.
My face hurts to death after using it, but I don't feel this way when using other skin care products. I am also sensitive to muscle use and speechless.
I used it for almost a month, and it really didn't irritate me. Red blood is not as obvious as before, and my face is not itchy and sensitive. I'm in love ~ a little excited ~
The follow-up effect is very good ~ at first, the T area will be stuffy, so when I use it later, I mainly apply it on my cheeks, and the oily area will pass ~ my cheeks will get better gradually. I am oily, T-zone is oily, and my cheeks are a little rough. After using this lotion, my cheeks really healed! Maybe buy a big jar of cream or lotion in the future ~?
I think it's classic, too I fell in love with the series as soon as I used it Absorb well, not oily or greasy. When you use it at night, your face is refreshing during the day.
I didn't see the whitening effect.
I don't know why I used this product after washing my face recently ~ I think it seems that I used this product in winter 1 1 and 65438+February, and now it's almost March. I have mixed skin. I feel a little oily when I use it at night, but I get oily when I get up in the morning and go to bed at night, but many comments say it's not oily …
It still stings after using it for a long time, not sensitive muscles.
Compared with Stafford, this one is a little picky about the skin. I rubbed it twice, and both of them appeared coquettish, and the local skin was red, which will get better after 3 hours. The moisturizing effect is good in Bista Ford. Whitening doesn't matter, just try to be gentle. Summer is fine, not greasy.
The whitening effect is obvious, and the oil control has a little effect, but it will make the skin very sensitive. When I used Stafu, my skin was healthy, just healthy, and nothing happened. I've used this for 8 days, but it's still uncomfortable to wipe my face, and red blood began to appear. I can't stand other skin care products at the same time. It seems that everyone's tolerance is different. Maybe the normal version of this brand is more suitable for sensitive muscles. When this bottle of wine is used up, it will be returned to Stafford.
It's been used for a week, and it does have a repair effect. It turns out that washing your face once will dry and peel off, but it won't after using this. It feels particularly suitable for dry skin. Other effects will be discussed later.
I heard a friend say it was good, so I bought it and tried it. I'm really not disappointed. My skin is seriously sensitive, and it is very dry because of the imbalance between water and oil. After using this product, I have no allergies, and the allergic symptoms on my face are much better than before. It is emulsion-like, refreshing and not greasy, and the hydration is not so dry! Very easy to use! I will continue to buy back when I run out!
The texture of the emulsion is still refreshing, not heavy. I rubbed it on my face for the first time, and it hurt a little. I'm particularly sensitive. I can't use Kiehl's high moisturizing series, but it hurts when I rub it. This is possible. I feel a little used to it after 2 or 3 days.
Comments: After reading so many user feedbacks, my heart actually collapsed, with mixed feelings. Feel for yourself.
If any product feels itchy on the face, it is recommended to stop using it. You can't let your skin make concessions to accept this kind of stimulation. What your skin needs is a gentle moisturizing product. You know, ingredients that irritate the skin will accumulate in the skin, and if they accumulate to a certain amount, they may cause skin allergies.
I really don't know what to say. When I used it, it really didn't have a repair function, and the taste was so bad that it hurt to wipe my face. It hurts even more when you run out. I don't know where I got the courage. It took me so many days.
The experimental spirit of this user is not worth promoting, and it is completely at the expense of hurting the skin. It hurts when you put it on your face, and it hurts even more after you use it. It hurts for so many days! More dedicated than a mouse!
Remember, you can't adapt your skin to skin care products! The correct way is to adapt skin care products to your skin.
Three. comment
CeraVe night facial moisturizing lotion
1. Pick the skin. Officially recommended for normal and dry skin. Although the product description has a repairing effect, it is not recommended by the government for sensitive skin and oily skin. Don't try sensitive skin.
2. Make sure whether you can tolerate nicotinamide before buying. Nicotinamide is a skin-picking ingredient. Many P&G whitening products contain nicotinamide, such as small white bottles, small green bottles, small light bulbs and so on. If you have used products containing nicotinamide and can tolerate them, you can buy them.
3. The moisturizing effect is good. After all, it contains structural lipid components, and with normal moisturizing components, the moisturizing effect will not be bad.
4. Repair depends on self-renewal of skin, and skin care products cannot be repaired. Structural lipid components can moisturize and slow down the exfoliation of the outer stratum corneum. Repair depends on the self-renewal of the skin, and deep healthy cells gradually replace the damaged cells on the surface with metabolism.
