knock on the blackboard!
It's time for class 7 again today, are you ready!
Recently, many little sisters always tell me that they have a myth~ When they go shopping, they can't help but buy a lot of makeup products every time. It must be said that the use of our family's products is more effective and helps absorption. What about the result of
? Of course
bought bankruptcy!
I remember when I first started learning skin care products, I felt that some skin care products would stain my face, the whole face was really shiny and really uncomfortable, and then I immediately threw away the skin care products I bought! !
felt like being cheated by the counter again, and then violently complained to the little sisters around! Z2z
Sometimes, I buy some skin care products and immediately rub it on my face to feel refreshed, so I feel very happy, I think I bought the right products that are easy to absorb. The value of this money! Z2z
But after years of researching skin principles, I found that this is not the case. Most skin care products cannot be "absorbed." what is this?
Today, I will tell you the little fairies. Is
a guise or the truth? Will
skin care products really be absorbed by the skin?
Skin is a barrier to protect you
Why do humans grow skin is to form a super strong barrier for the human body, so that all kinds of bad things in the environment, such as bacteria, viruses, sunlight, etc., will not It hurts us directly.
There are six or seven layers of cells on the skin surface to form the stratum corneum, followed by the granular layer, the transparent layer, the spinous layer, and the basal layer. Each layer has several layers of cells.
We can first divide the skin into three layers: epidermis, dermis, and subcutaneous tissue.
epidermis layer: located in the outermost layer of the skin, helping the skin to stay below the damage of foreign substances;
dermis layer: located below the epidermis layer, composed of elastic fibers and collagen, responsible for skin elasticity and aging;
subcutaneous tissue: the most The bottom layer is composed of fat cells, which can keep the human body warm and protect the skin.
Layers of skin are very hydrophobic~ this is why you will not swell up into a super fat man when you go for a swim.
The water outside can't get in, and the water inside can't flow out naturally. Think about the pores constantly seeping water! ! very scary! ! I still don't want to.
Therefore, if cosmetics are to be "absorbed" into the skin, it needs to go through many levels. Most of the molecules of skin care products are difficult to penetrate this barrier, and a small part of the absorption rate is slower than that of snail crawling, and you can't feel it at all. The
advertisements called "" instantly absorb the " formula", and the full effect reaches the bottom layer of the muscle and the dermis. If you eat good nutrition, don't be fooled! !
So will skin care products really be absorbed? The answer to
is: incomplete.
is not so much absorption, but the princess thinks it is more appropriate to use penetration. Generally, the stratum corneum, hair follicles, sebaceous glands and sweat glands of our epidermis play the role of absorption. They are the initial parts of skin care products. For these organs, skin care products are most important to maintain proper hydration of the skin surface. The little fairies like
will definitely ask me, you have said so much, what kind of skin care products will be absorbed?
Fat-soluble active substances can still be absorbed, a little bit~ (smiling face)
Generally speaking, skin care products are divided into:
water-oil mixed type, cream, lotion, etc. and fat-soluble types, among which the fat-soluble substances will be Penetrate and absorb, passing through the gap between keratin and cells. Z2z
Water-oil-mixed and water-soluble water-soluble substances increase the water content of the stratum corneum, which is then absorbed through the skin and is also located in the stratum corneum. Z2z
Hair follicles, sebaceous glands, sweat glands, these organs are extremely weak in the absorption of skin care products, and usually only absorb fat-soluble substances and fats in water-soluble oils-Soluble skin care products.
It’s okay if you don’t understand the above.
In short, pure water, oil-free type cosmetics basically only act on the surface of the skin, while the fat-soluble active substances in emulsions and essential oils will be penetrated by into the skin .
However, there are a lot of PH value, molecular size, concentration, hydration environment, and the thickness of the stratum corneum. If you consider the absorption of these problems, the "absorption" of the real skin is almost negligible~ the more the
absorbs More is better?
Be careful of skin damage!
Since you said that, there may be a little fairy who wants to ask again, there are still some ingredients that will be absorbed! Is it better to absorb as much as possible? Z2z
is not~! ! ! It is good to keep it in moderation, don't pursue too much absorption~ Too much absorption will harm the skin! Z2z
The main organ absorbed by the skin is not the pores! This is not a sweat gland either! Don't think that water will seep into porous skin! ~ Actually, the stratum corneum is really effective. If you want to increase skin absorption, there are two ways. Z2z
1. The thinner the stratum corneum, the more it absorbs, and the dense structure of stratum corneum cells is loose.
2, the higher the water content of the stratum corneum, the more it is absorbed.
But if you really do this, the thin stratum corneum will turn the skin into a poor sensitive muscle . The loose cell structure leads to poor skin tolerance, moisture cannot be locked, and a stratum corneum with too high water content. , It will make the pores bigger and the skin will become ugly.
Regular exfoliation and moderate massage can promote absorption.
But don't go too far to "eat" the ingredients of skin care products. One day when your skin becomes sensitive, you will regret it! ! !
If something really penetrates into the skin quickly, you must be careful of poisoning! Crying without tears~
of course~
Little fairies don’t think that
will dry things badly when you rub them. Good cosmetics not only need to have good results, but also be comfortable to use. A bottle of petroleum jelly and glycerin can achieve a moisturizing effect. Why buy such an expensive product? Does
have major psychological factors that make you feel comfortable when you use it on your skin, and does it smell like? After all, major brands still take this aspect seriously.
does not work unless absorption!
give me attention here! Not all skin care products need to be absorbed before they have an effect. Clean, peel, soften, sunscreen, and lock water all do not need to be "absorbed"!
• Topical products:
products that are generally ordered, such as anti-acne gel, this kind of texture can actually be applied topically, regardless of whether it will be absorbed, part of its effect is to reduce inflammation and calm. It's like the topical medicine you usually get injured by a fall.
• Sunscreen: For
sunscreen products, the most important thing is to form a protective net on the surface of the skin to reduce the damage of ultraviolet rays to the skin and to bounce it back, so there is no need to consider the issue of absorption.
•Whitening:
As for whitening products, there are a lot of ingredients that are carried out by various acids, such as "fruit acid rejuvenation". Its principle is to use acid to make the skin surface old. The keratin and the melanin deposited on the old keratin are metabolized.
So it's like a wall, no more absorption, but it's the same as sunscreen products, you must take care of the corners of the face, don't have any here, then your skin tone is uneven It's my own business.
• Moisturizing category:
Many people need to consider moisturizing and moisturizing, right? In fact, moisturizing products are mainly used to make the surface of the skin smoother and prevent the loss of moisture from the cells. The effect is basically achieved by wiping.
moisturizing mainly relies on glycerin and other ingredients to absorb moisture in the air and moisture on the skin's surface, and then form a protective film for moisture. So as to lock the moisture added by skin care products on the skin surface, so as long as the moisturizing products cover the face well, basicallyThe problem is solved.
Many "teachers" ask you to massage, hoping that you can really spread the skin care products evenly, not thick here and thin at the other side~
•Anti-aging category:
...I can only say about this, nothing is. Age can be reversed~ but only through various means to slow down aging, pores aging, wrinkles caused by aging, if not through medical beauty, basically irreversible~
think that there are too many words you can’t understand, it’s okay, anyway, my little Fairies, as long as I remember skin care products, except for the fat-soluble active ingredient in the skin care products, which can be "absorbed" by or , the others basically stay in the stratum corneum and do not need to be deeply "absorbed" Yes, remember, don’t be fooled by the counter! ! ! !
Today I am here in this class~
In those years we were fooled by convention
