Acne leaves a lot of bruises:
For teenagers, acne can be the biggest headache, as it directly affects appearance .and is difficult to hide with layers of makeup.
And then, after going through a period of worrying about acne, I have to face stubborn dark spots and melasma and from here the hard and constant treatment of tanning begins.
Why is it necessary to treat melasma on the face:
Unlike acne, dark brown does not cause us pain but sticks to the face insistently, and sometimes the longer it lasts, the more severe it becomes and it is difficult to completely cure it.
Although dark pigmentation does not affect health much. it will make the skin uneven. making us lose confidence. In addition, frequent use of foundation.
or concealer preparations with a thick texture to cover bruises will make the skin clogged with pores. causing acne, and then leaving dark spots in a vicious circle.
For light bruisesك
it is easy to cover with concealer, but for long-lasting bruises. especially for those that penetrate deeply into the skin, a large amount of cream should be used.
The concealer makes the foundation thick and easy to crack. unnatural, not to mention that we can not always make up correctly
And the best makeup is also beautiful skin. Therefore, the treatment of dark spots on the face. albeit difficult, is extremely necessary.
What is a dark spot What causes dark spots?
To be able to find a solution to a problem, we first need to understand the cause of the problem.
(Derived from melanocytes) in that skin, area to protect the skin. and accidentally form deposits on the skin, leaving bruises.
And this is also the reason not to squeeze acne arbitrarily. because the more we squeeze it. the more it damages the stratum corneum, further stimulating the pigments. Melanin that area of the skin makes the skin darker and very ugly.
At the same time, the combination of sunlight makes the bruise darker and darker, and longer it lasts.
The photo above describes the process of the formation of dark spots from sunlight. but you can imagine when the skin is damaged, it will be the same.
Melasma:
also known as melasma, is a headache for middle-aged women, largely due to hormonal changes during pregnancy or with women who also use birth control pills.
They may have hyperpigmentation because their bodies go through the same type of hormonal changes that occur during pregnancy.
In addition, melasma is especially common in the case of women who often work in a sunny environment without using sunscreen for a long time. The reason for this can be seen in the following study: in sunlight, there are two types of ultraviolet radiation.
UVA and UVB. UVB is more harmful to the skin than UVA but can be blocked by concrete and glass walls as well as clothing. but even indoors it can be affected by UVA rays. So if you haven't used sunscreen for a long time ،
In addition:
melasma is also caused by liver heat, aging, and hormonal changes. or the harmful effects of heavy metal poisoning such as (mercury, lead, etc.)....) Or corticosteroids in the cream mixture.
Basically, it is derived from dark spots or costmelanin, but don't rush to hate memelaninif you allow it.
This is the body's first skin barrier. as it helps prevent ultraviolet rays and oxidants from entering the skin, and helps the skin avoid damage. and also protects the skin from cancer.
Many people consider Melanie, it's like a double-edged sword. good for health but causing ugly skin.
How is skin pigmentation treated?
Many modern technologies were born to serve the purpose of treating human melasma. but these methods are expensive and always contain many dangers. and dark pigmentation products on the Vietnamese market men can now mix a lot of mixed creams. and they can be used for a while.
Skin erosion, and skin intoxication, make skin pigmentation worse and worse. So you have to look for a product carefully before applying it to your face. There are actually groups of substances that treat dark spots that are still safe for the skin and in this article,
I will focus only on applying these substances to support the skin through topical application. To facilitate the transfer of this content. I will divide the special groups for melasma treatment into 3 different groups based on use.
Group 1: affects the enzymes involved in the synthesis of melanin
Hydroquinone inhibits enzyme production and destroys melanocytes, it is a golden component in the treatment of melasma.
However, it should only be used with hydroquinone of less than 5% because you don't want your skin to easily catch the sun's rays or turn blue. right, However, hydroquinone is also recommended to be harmful to humans.
so it should be used in combination with other substances such as glycolic. Gentle acid Kojic acid reduces irritation and increases the effectiveness of treatment.
In addition:
scientists are now also finding other functional groups that can replace hydroquinone:
The form is tranexamic acid, sometimes the effect itself is better, but without leaving any side effects.
Alpha arbutin and kojic acid: Arbutin has a lower skin-lightening ability than hydroquinone, however, it is more stable and leaves fewer side effects, especially when combined with koji acid. it acts as an oxidant and prevents the harmful effects of free radicals.
In addition, in this group, there are substances vitamin C - inactivityenzyme tyrosinase that should be effective but still very safe. but easily oxidized, soluble in water but unstable.
so manufacturers have changedpurified vitamin C to functional groups derived from vitamin C as ascorbic methyl acid.
EAA and Nanovitamin C combined with paintinglipoparticles. make it more stable but still quickly penetrate the skin.
There are also other functional groups such as Azelaic acid, licorice،…
Group 2: helps prevent the migration of melanosomes
Niacinamide is safer than hydroquinone. but it should not be used with vitamin synthetase because it is easy to cause reddening of the skin, it can still be used with derivatives instead of vitamin synthetase. as I mentioned above.
Group 2 also contains a group of soybean derivatives (soy extract) that have been shown to have very effective whitening abilities.
Group 3: functional groups help to increase the cycle of skin regeneration:
remove dead cells, stimulate the production of new cells, and lighten skin tone.
It consists of AHAOBHA, phase, and retinoid.
AHA:
this acid acts as a chemical exfoliant, helping to stimulate the natural .exfoliation. of the skin, resulting in glowing, smooth skin.
BHATHIS is an oily acid, so it can penetrate deep into the pores to help remove dirt. clogging dead cells.
PHA:
similar to the two ingredients mentioned above, PHA peeling is also possible. But thanks to its large molecular structure, it helps to enhance its effect on the surface of the epidermis without affecting the underlying skin layers.
PHA also can absorb moisture. so the skin will not be dry and tight after peeling with PHA.
Retinoids are derivatives of vitamin A. Retinoids are known for their ability to stimulate collagen in the skin, and reduce wrinkles. stimulate cell formation in the epidermis and help increase mitotic activity in the epidermis, supporting the process of cell division ...
Note when treating melasma after acne
Spots often do not appear naturally, but they are almost always accompanied by acne spots after the acne is gone. they will begin to darken, and the treatment of dark pigmentation is difficult.
but for sensitive skin after acne, it is still difficult. When you have acne, that is, your skin is damaged, it is necessary to take care of the skin very carefully. so that the skin can be restored, renewing the protective layer of the epidermis.
and also soothe the skin after acne before starting the step. In the next step. The ideal ingredient to soothe the skin is panthenol,
to ensure absolute safety for the skin, acne should be completely cured and then the use of cream to treat dark spots will be more effective.
You should understand the skin problems before choosing the ingredients and from there choose reputable products to get the best skin.
