There are three main reasons for darkening:

Melanin, which affects the complexion, is constantly produced.

Ultraviolet radiation accelerates the formation of melanin.

Aging cells accumulate on the surface of the skin, resulting in the appearance of dark spots or uneven skin tone.

In response to the above causes, the ARTISTRY whitening series can effectively improve the problems of darkening and pigmentation

The whitening complex inhibits the production of melanin.

The formation of melanin is controlled by a substance called tyrosinase, the activity of which plays a major role in pigmentation. If the metabolism of melanin is not smooth, it will lead to a large amount of pigmentation, which will accumulate locally, and the color of ** will deepen or form spots. Therefore, inhibiting tyrosinase biosynthesis is one of the keys to whitening.

ARTISTRY has obtained a U.S. patent for a new technological breakthrough that combines effective whitening ingredients such as bearberry, lemon and cucumber with acerola cherry extract to develop a whitening complex that can effectively inhibit the activity of tyrosinase to reduce the formation of melanin.

Sunscreen ingredients protect against UV rays.

UVA and UVB in ultraviolet rays darken the skin and harm the health of the skin.

UVA can penetrate the wall or glass to attack the dermis and even the subcutaneous tissue, reducing the elasticity and activating tyrosinase to accelerate the production of melanin. Causes premature aging and long-term, long-lasting damage.

UVB, acting on the epidermis, causes immediate, severe** sunburn while accelerating the production of melanin. If it is overexposed, it is easy to cause cancer.

SPF: SPF and PA

SPF (Sun Protection Factor), an international standard used to evaluate the effectiveness of sun protection against UVB, is followed by a number.

PA (Protection Grade of UVA), the standard for the identification of the sunscreen effect against UVA, is followed by a " " sign.

Moisturizers with SPF15 and PA are often enough for everyday life, and ARTISTRY moisturizers contain this level of sunscreen to protect against UVA and UVB rays.

Willow bark extract gently exfoliates dead skin cells.

Willow bark extract gently removes dead skin cells on the surface for a more even, radiant complexion.

**Black should be divided into two situations to choose:

First, if the congenital ** is relatively dark, it is due to genetic skin color problems, and no special treatment can be done.

Second, dark skin tone is seen in poor sunscreen, or inflammation, which leads to post-inflammatory pigmentation, and this type of dark skin can be improved by the following methods:

1. Don't stay up late and pay attention to going to bed early;

2. Drink more warm water and supplement fruits and vegetables;

3. Eat less snacks, drinks, and frozen things;

4. Exercise more;

5. Do a good job of strict sun protection;

6. You can use the best method, you can take reduced glutathione orally, or use intravenous infusion of reduced glutathione plus vitamin C, or you can use whitening and blemish serum, such as fullerene essence or tranexamic acid serum.

**Black, possible causes include genetics, sun exposure, use of certain medications, rubbing melanosis, kidney disease, and other systemic diseases.

1.Heredity. Parents are darker and have more melanin, and inheritance to children may be manifested as **black.

2.Solarization. Exposure to the sun or long-term exposure, the increase and deposition of melanin, ** will turn black.

3.Use of certain medications.

If you have recently taken certain special sedative drugs, it will also increase melanin precipitation, ** blackening.

4.Rubbing melanosis.

The specific mechanism of this disease is not known, but excessive use of bathing force or repeated rubbing can darken the disease.

5.Kidney disease.

Kidney disease leads to ** black, mainly in patients with chronic renal failure. The glomerular filtration rate is reduced, and metabolic wastes accumulate in the body and cannot be discharged, which is poison for the human body, and these poisons will make ** black.

The darkening caused by acquired factors is often reversible, and attention should be paid to removing it, such as avoiding excessive exposure to ultraviolet rays, positively, primary diseases, etc.

There are many reasons for darkening, and most of the time it is due to metabolism. Some people will suffer from lack of nutrition due to long-term lack of sleep, resulting in more darkening and wrinkles. Malnutrition can lead to darkening and may also dry out or shrivel.

**Blackening can be accompanied by brittle and easy hair loss.
