Spot removal has always been a trendy topic in the beauty industry, and it is the wish of every beauty-loving MM to have a flawless skin like an egg. But how much do you know about blemishes?
Pigmentation is a kind of common facial brown or melanin pigmentation, cosmetic skin disease formed by the increase of skin melanin. Melasma is one of the pigmentation spots.
Only when we understand the basic characteristics of melasma, we can prescribe the right medicine.
Basic meaning: Melasma is also known as liver spot and butterfly spot. It is generally manifested as yellow-brown pigmentation on the face, mostly symmetrical butterfly-shaped distribution on the cheeks. It is common in adult women, especially in women of childbearing age, and can also occur in men. High estrogen level in the blood is the main reason, and its onset is related to pregnancy, long-term oral contraceptives, menstrual disorders, etc. Stretch marks also belong to chloasma.
Clinical manifestations: The rash is light brown or yellowish brown spots of irregular shape with different sizes and clear or unclear edges, smooth surface, no local inflammation and scaling. No self-consciousness, most patients will last for several months or years, aggravated by sunlight. It deepens in summer and decreases in winter.
Formation factors.
1, imbalance of yin and yang in human body: liver qi stagnation, resulting in blood stasis on the face; weak spleen and stomach, qi and blood cannot moisten the face, damp heat rises to the face to form spots; kidney yang deficiency, yang diffusion, blood stasis on the face to form chloasma.
After pregnancy, the placenta secretes more androgen and progesterone, so symmetrical chloasma is common on the cheeks of women during pregnancy, but after the production of androgen and progesterone in the body returns to normal, most of the spots will naturally reduce or disappear.
3.Drug factor: 9%~20% of women who take oral contraceptive pills for a long time are prone to chloasma, and some people even have facial spots after taking oral contraceptive pills for one month: in addition, taking high blood pressure, diabetes medicine and eating more photosensitive food, such as celery, parsley, carrot, etc. are also likely to cause chloasma.
4, other factors: some chronic diseases such as chronic hepatitis, tuberculosis, etc. will lead to the enhancement of tyrosinase activity and increase of melanin production, while the body’s own ability to exclude melanin is weakened, once melanin cannot be discharged from the body in time, chloasma will also be produced on the face over time; in addition, improper use of cosmetics will also aggravate and accelerate the formation of chloasma, many causes of pigmentation.
For getting rid of melasma, we often use foods rich in vitamin C like lemon in our life and put them on our face but the effect of removing spots will be very, very slow. Dahurica dahurica to get rid of spots but requires long term conditioning. Whitening masks, especially those containing fluorescent agents, make the face look white, but in fact do not get rid of melanin, but add a metabolic burden to the skin.
To inhibit the formation of melanin, there are two ways: the first is sun protection; the second to speed up the metabolism of melanin.
Second, pigmentation is the formation of melanin accumulation that cannot be metabolized.
There are two reasons. Firstly, too much melanin is produced; secondly, the skin is unable to transport melanin normally, resulting in the accumulation and formation of pigmentation.
Is there really no once and for all solution? We can appropriately take the help of medical beauty means and use laser skin care equipment to remove spots, but not all laser equipment is very effective in removing spots.
Third, the same equipment is used to remove spots, why some have good effect and some have bad effect?
1.Melanin is generally distributed in the true epidermis of the skin, but the distribution of different pigmentation levels are different. The energy of some laser devices cannot reach the layer where the pigmentation is located, so it is an ineffective treatment at this time.
2.Some laser devices can reach this layer, but part of the energy will be absorbed by water first, and the energy of removing pigmentation will be weakened, so the effect is not good.
3.Some energy can reach and exceed the level where the melanin is located, so the pigmentation can be removed, but the excess energy will harm the normal tissue. It will cause blistering and pigmentation.
Therefore, before doing the treatment, you need to pay attention to several points
1.Understand what kind of pigmentation you have and its distribution in the skin;
2.Understand your skin condition, whether it is sensitive skin or not;
3, choose the laser equipment with balanced energy, which can remove the pigmentation without damaging the skin.
