In various skincare product advertisements, we will see a very high-frequency descriptor called baby-like skin.
Do you know why a baby’s skin is soft, smooth, and elastic? Because baby skin has the highest water content in a person’s life, about 69%. The water content of a newborn’s skin can even reach 74.5%.
As we age, the water content of the skin will gradually decrease under the multiple effects of hormone levels, aging skin cells, and seasonal environmental changes, so in order to keep the skin soft and elastic, hydration and moisturizing have become a top priority.
Studies have shown that the water content of the skin decreases significantly with age after the age of 25. Therefore, from the age of 25 at the latest, hydration and moisturizing should be done. What exactly should be done?
1. Hydrating skincare products, the effect is only 1 minute
First of all, let’s understand the role of hydration and moisturizing.
In life, when we feel that our skin is no longer so soft, smooth, and shiny, the first solution is to use some skin care products, skincare guide after listening to your request, usually will say: you are because of skin dehydration, need to hydrate, moisturizing. Then you will be advised to buy sets of water, milk, essence, cream, mask, etc.
After buying, looking at a pile of bottles and jars, do you think.
Do I really need so many kinds? This is too much, can I just apply the most important ones?
In order to solve these confusions, we need to first understand what hydration and moisturizing are.
Have you all had this feeling that every time you wash your face and look in the mirror, you will find that your skin is fairer and more hydrated than usual? Do you know why? It is because when we wash our face, the skin surface of the stratum corneum absorbed water so that the skin will look hydrated; skin surface cells absorb water, forming a smooth surface so that the refractive properties are better so that the light looks bright and white.
Before washing your face, there will be gaps between the cells of the stratum corneum that have not absorbed enough water, just like there are big and small potholes on the road, so that the road, when the light shines on it, will also look bright and dark unevenly.
After washing the face, the cells of the stratum corneum on the surface of the skin absorb water and are arranged neatly and closely one by one, just like a freshly paved road, flat and smooth, and when the light shines on it, there will be reflections and it will look bright.
But this hydration is temporary. A minute or two after washing the face, we will find that the skin is back to its previous yellowish-black or roughness. So, in order to have hydrated, fair skin, what we need is to always let the skin surface stratum corneum cells absorb fully water, which means continuous hydration and moisturization all year round.
So, oily skin doesn’t need hydration?
The water, we usually use soft skin water, moisturizer, spa water, etc., rub or spray on the face, just like the process of washing the face, this water in the skin surface stays for a short time, the role is only in the stratum corneum, so, for the skin’s moisturizing effect is very weak, a couple of minutes the effect is gone.
Hearing this, some friends will ask, why do we have to spend so much money to buy all kinds of water?
In fact, the main role of using a variety of water after cleansing is to balance the PH value of the face. Even milder cleansers, even closer to the facial skin, will cause a change in the PH value of the face after cleansing, so you need to balance it with water agents after cleansing.
What really helps to hydrate the skin in a lasting way is actually the moisturizing step, similar to what we call locking in moisture.
Moisturizers are generally made up of two major components, moisturizing ingredients and sealing ingredients, neither of which can work without the other. However, a variety of moisturizing ingredients and closed components, have their own advantages and disadvantages, suitable for different skin types.
2. How to choose the right moisturizer for different skin types
moisturizing ingredients including glycerin, urea, hyaluronic acid, etc.
Glycerin is not grease, it has a strong water-absorbing effect and is often used in moisturizing products because of its good value and low price. However, its concentration should not be too high; the higher the concentration, the greasier it is.
Allantoin and its derivatives allantoin are also commonly used moisturizers, relatively greasy, not soothing, and generally more popular with dry skin people and the elderly.
Hyaluronic acid, now the most well-known moisturizer, is also called hyaluronic acid, which is powerful because it can absorb 500 times its own volume of water.
These three components, glycerin, and urea components are relatively cheap, and generally within fifty dollars can be handled; while hyaluronic acid components are more expensive, the production process of different manufacturers, the price varies greatly.
Of course, only hydration without water storage is not possible, you need to close the composition.
Closed ingredients include oils, such as olive oil, and lanolin; silicones, such as Cyclopentasiloxane, dimethicone; ceramides, squalane, etc., their role is to “lock water”.
The skin’s sensibility is different for different closed ingredients.
Oil is more sticky; silicone is less thick and slippery after use, but it is a false sense of slipperiness and tends to clog pores; ceramide, originally contained in our skin, more than 40% of the sebum in the stratum corneum consists of ceramide, which not only moisturizes but also helps restore the barrier function of the skin; squalane component can be compatible with the sebum on the skin surface to form a sebum film.
Therefore, relatively speaking, the two ingredients, ceramide, and squalane have the best perception.
The principle of moisturizer selection is 7 words: comfortable and non-greasy after use.
Different skin types should choose different textures of moisturizers in different seasons, as long as the skin feels comfortable and non-greasy after use, it is suitable for them.
For people with dry skin, in spring and autumn, and winter, you can use skincare products containing glycerin and urea ingredients, which are greasier and more comfortable, while in summer, you can use skincare products containing hyaluronic acid, ceramide, and squalane ingredients.
People with oily skin can choose those containing hyaluronic acid and ceramide ingredients all year round.
For people with normal skin, you can choose skincare products containing hyaluronic acid, ceramides, and squalane ingredients all year round.
For people with combination skin, you can choose skincare products containing hyaluronic acid, ceramides, and squalane for the whole face in spring and autumn, and winter.
Common moisturizing skincare products would include essence, lotion, and cream. These three moisturizers may be similar in composition, but there are differences in molecular weight size and water content, generally, the active ingredient in the essence has a small molecular weight, and the cream is the largest. The smaller the molecular weight of the ingredients, the easier they are to absorb through the skin, so the order we use them is essence first, then lotion and cream.
Lotions contain relatively more water and do not feel sticky after use, so people with oily skin will choose more, while people with dry skin can choose in the summer, and in the winter, they also need to use creams.
For people with combination skin, you can use lotion on the whole face, and if the cheeks are still dry, adding a layer of cream will do.
3. Moisturizing mask full strategy
The mask can be a quick hydration tool and is used more frequently before appointments, in spring and autumn, and in winter.
Mask on the surface of the skin, forming a warm effect, can make the pores open, moisture and nutrients absorbed more deeply; finally, the mask paper on the surface of the skin closed pores, can effectively prevent the evaporation of water. Therefore, the mask hydrates quickly and deeply.
The hydration effect of the mask is certainly divine and effective, but the most taboo thing we can do is to use it every day.
Except in the acute period of certain diseases, or after doing medical beauty programs such as photorejuvenation, doctors will tell patients to use certain medical masks every day, we can’t superstitiously believe in the magical effect of masks and use them for hydration every day. Because, there are also fragrances, preservatives, alcohol, and bacteria in the mask, which can cause skin irritation, and allergy, and even damage the barrier function of the skin and cause skin sensitivity.
So the correct way to use is: 2 times a week is appropriate, very dry skin can be used 3 times, each time about 15-20 minutes can be.
Moisturizing masks come in different textures, such as cream, gel, and paper. Using one kind of mask a day will be fine; after the mask is used, generally the skin surface will still be left with some essence, it is recommended that you, do not feel pain, if you can absorb it, do not wash off, can not absorb it, wash off. Otherwise, causing a sticky feeling on the surface of the skin, but also affect the subsequent skincare process.
In addition, the mask is a quick hydration tool. After applying the mask, the skin water content rises significantly and you need to use a moisturizer next to slow down the water loss.
