Sheep have recently learned a little new about skin color: genes have determined that our skin color cannot be changed.
The scientific whitening methodology does not mean to change our skin color, but to adjust the distribution of pigments in the skin.
Let's brighten on the basis of the original skin tone, from dark cold skin to light cold skin, from dark warm skin to light warm skin.
Although the skin color is different, it is based on its own healthy and bright state
And it is impossible to change people from warm skin tones to cool skin tones.
Based on this premise, we are going to talk about the "whitening combination treatment" in medical aesthetics today.
Water light, microneedles, photoelectric... They all say that they can whiten, why did they do it but did not become white?
How exactly will it be more reasonable to match? Different people have different choices
Different people, different blacks
Before the sheep have told everyone the general direction of whitening ideas: first remove the flaws, and then the overall brightening.
The combination of picoseconds + water light also follows this principle, but is it suitable for everyone?
In fact, there will always be people who make different voices, and I understand the reason, but I really haven't turned white
The correctness of logic does not equal the correctness of decision-making.
You and I have different "black" methods, destined to "whitening combination treatment" is also divided into many kinds...
Have you ever wondered why everyone's skin color is different?
There are many determinants: the content of melanin particles, the proportion of carotene, the thickness of the skin...
These will affect the presentation of skin tone, let's say one by one -
1. The content of melanin particles will affect the depth of skin color
First of all, we are most familiar with melanin, we all know that the content of melanin is high, which will make people black.
But in fact, the number of melanocytes in Asians and whites is similar.
However, we secrete more actively, and the production of melanin particles is higher (fork waist.jpg
Everyone is yellow, but the one with more melanin particles has a darker complexion
2. The ratio of carotenoids affects the type of skin color
All colors are made up of three primary tones of red, yellow and blue, and the flesh color of the skin is no exception.
It's just that Asians have more carotenoids in their skin, so they look more yellow
The ratio of carotenoids to hemoglobin and melanin is different, which forms a different color tone.
If you take the neutral skin tone as the standard, this group of people belongs to the carotenoid content is just right.
Then cold-tuned people are more red pigments; warm-tuned people are more carotenoids; olive-toned people are less red pigments.
People with the same pigment ratio, the more pigment content is the dark skin color, and the less content is the light skin color.
3. The thickness of the skin will affect the presentation of the skin tone
Color is also related to light, so the light transmittance of different skin states will affect the judgment of skin color, there are three main points -
Too much of the protective stratum corneum accumulates, which affects the light transmittance. If you can't see the neutralization of the red pigment, the more yellow the skin.
In the same person, the low light transmittance and low blood transport (less red pigment) brought about by the slowing down of metabolism after the elderly age will appear more yellow than before.
The thicker the layer of particles that filter ultraviolet rays and the transparent layer that locks water, the more "white" the skin, and the white mentioned here is actually translucent.
The same person, when he was young and now, is white-skinned, but the skin state of his youth has a girlish sense of transparency
Since carotenoids are abundantly present in the dermis layer, the collagen content in the dermis layer decreases, which also makes the skin more yellow.
Scientific whitening combination treatment, more effective with half the effort
After the previous analysis, we can summarize the following points:
· The fewer melanin particles, the lighter the skin tone
· The ratio of carotenoids affects skin tone judgment
· The stratum corneum is too thick and the collagen loss will appear yellow
· The higher the moisture content of the skin, the more translucent the complexion
Therefore, different people can choose different whitening combination treatment strategies - whitening, yellowing, brightening.
1. Sisters with deep skin, focusing on solving melanin
The idea of this type of combination therapy is to help melanin decomposition + accelerate melanin metabolism.
The medical aesthetic means that can be used to help melanin decompose are Q-modulated lasers: Q/picosecond/super-picosecond.
After the Q crushes the melanin, it takes away the melanin by scab shedding;
After the picosecond and super picosecond crush melanin, it is metabolized by the human body.
They correspond to the two pathways of skin excretion and kidney metabolism, respectively, and different combination therapies are born.
Q-modulated laser + tranexamic acid
The selective photothermal action of the Q-modulated laser can only solve the melanin particles, but the transparent melanocytes cannot solve it, which requires tranexamic acid to inhibit from the source.
Since both tranexamic acid and tyrosine have a hydroxyl group (COOH), they compete for tyrosinase, reducing melanin production from within.
Picoseconds / Super Picoseconds + Base Water Light
Because the purpose of our water light needle here is only to help metabolism, so the basic water light that can replenish the base can be watered.
For example, Haiyuelan and Bi Cuishi.
2. Sisters with yellowed skin, dilute carotenoids
The idea of this type of combination therapy is to increase the collagen content of the dermis layer.
As mentioned earlier, carotenoids are abundantly present in the dermis layer, and too many carotenoids can make our complexion yellow.
Collagen supplementation will dilute the yellow tone of the skin, and the skin color of small babies rich in collagen content will rarely turn yellow.
Therefore, the combination treatments we can choose are: gold microneedle / ordinary microneedle + collagen introduction.
Ordinary microneedles are mechanically stimulated to increase the collagen content under the skin; gold microneedles are mechanical stimuli + radiofrequency energy, the effect will be much better than ordinary microneedles, but the price is also more expensive.
Collagen introduction, on the other hand, is directly replenished to the skin through atomization. It is not a new technology, but the sheep recommends that everyone go to the dermatology department of the regular tertiary hospital for treatment.
3. Sisters with dark skin, the skin is brightened as a whole
If you want to brighten the skin as a whole, you need to improve the light transmittance of the skin - reduce the stratum corneum, thicken the granular layer, and the transparent layer.
The granular layer and the transparent layer itself cannot be directly thickened, but they both belong to the epidermal layer, so the overall thickening of the epidermal layer can indirectly thicken these two layers.
Therefore, the idea of this type of combination therapy is to reduce the thickness of the stratum corneum + increase the thickness of the epidermis.
The combination treatment we can choose is fruit acid + photon rejuvenation.
The former is to peel off the old waste stratum corneum, and the latter is to establish a new skin barrier and thicken the epidermis layer.
