1. What is Melanin?
Melanin is the pigment that gives people skin, hair and eye color. It is produced by melanocytes.All people have the same number of melanocytes. However, in each person, this cell makes more or less melanin. The more melanin the skin has, the darker it gets.
When melanin is concentrated in a number of places on the body, it will cause skin darkening, also known as hyperpigmentation. When this happens, some areas of the skin appear darker than the rest.
There are many treatment methods to remove the presence of melanin or reduce melanin production in the skin, but there are many risks and limitations.

Laser therapy removes the top layers of the skin, reducing melanin in the treated areas. Commonly used lasers are:Ablative laser: This method helps to remove the outer layers of skin and requires strong intervention. Non-invasive laser: This method is gentler than invasive laser, helping to promote collagen growth, skin regeneration. Intense pulsed light (IPL) is one such treatment. This technology uses pulses of light energy to heat and destroy melanin, eliminating brown spots. Q-switched ruby laser (QSRL): This method uses pulses of light to heat and decay melanin.

Sunscreen also protects the skin from harmful ultraviolet rays and slows down the production of melanin in the skin.
According to the American Academy of Dermatology, the best sunscreen will have criteria such as: having a broad spectrum of sun protection, SPF 30 or higher, and water resistant. Although sunscreen does not block 100% of UV rays from the sun, it can limit the amount of melanin produced in the skin.

Therefore, in order to implement this method, it is important to be patient and maintain it regularly.Turmeric: According to a 2012 study, the active ingredient in turmeric can reduce the synthesis of melanin. This active ingredient, called curcumin, has the ability to inhibit tyrosinase, which in turn will prevent the ability of melanocytes to make more melanin. Aloe vera gel: Aloe vera can reduce melanin production after sun exposure. Aloe vera contains aloesin, a compound that inhibits tyrosinase, according to research conducted in 2002. However, a more recent 2012 study determined that aloe vera had no effect. this use. Although the results of these studies are conflicting, people who use aloe vera gel still notice a skin-lightening effect.
