Description

A kind of whitening and moisturizing freckle-removing emulsion and preparation method thereof

technical field

The invention relates to a freckle-removing emulsion, in particular to a whitening and moisturizing freckle-removing emulsion and a preparation method thereof.

Background technique

Pigments are spots that are different in color from the surrounding area. Pigmentation is a common skin disease with brown or hyperpigmentation and disfigurement on the face due to the increase of skin melanin. It mostly occurs on the cheeks and forehead and is aggravated after sun exposure. There are four main causes of pigmentation: 1. Endocrine causes: Endocrine disorders are also an important cause of pigmentation in women. Changes in sex hormone levels during menstruation and pregnancy can affect the production of melanin. In addition, when the endocrine is unstable, it usually causes emotional instability, which can also indirectly cause the formation of pigmentation; 2. Living habits: Stress, partial eclipse, lack of sleep and other bad living habits can also increase melanin. Therefore, people with unstable sleep time have poor skin metabolism, which will affect the production of melanin granules; 3. Genetic causes: Autosomal inheritance is the main cause of freckles. Most of them start from children around 5 years old, mostly women, heavy in spring and summer, and light in autumn and winter. Spots from light brown to tan to the size of rice grains are symmetrically distributed on the face; 4. Ultraviolet radiation: Ultraviolet radiation in the sun is an important reason for the formation of stains, which is why sunscreen is needed in summer. When the skin receives too much sunlight, the epidermis produces more melanin particles, which absorb ultraviolet rays and protect the body from damage. Moreover, ultraviolet radiation can cause chloasma and common freckles to deepen in color.

And the processing method to stain at present mainly contains: 1, cover skin with powder fat or thick ointment, make it from sunlight and pollution infringement. But preventing the outside does not cure the inside, can not improve the color of the skin, and has relatively large side effects. 2. The use of laser beauty to remove freckles mainly uses laser therapeutic equipment to emit specific wavelengths. Lasers of different wavelengths will be absorbed by the color or pigment in the skin. When the pigment is slowly absorbed by the body, the color of the pigmentation will change accordingly. light. But after all, laser speckle removal is a "compulsory speckle removal" that relies on external forces, and it cannot stop the regeneration of spots from the source. 3. The cosmetics currently on the market are used, but most of them are mainly chemical raw materials. After random inspection by the national quality inspection agency, the content of harmful substances such as lead, mercury, and hydroquinone exceeds the specified standard by hundreds of times, and some even exceed 1,000 multiple times. Lead, mercury, etc. are toxic substances to human skin and nervous system, especially to liver, kidney and other organs, which can cause chronic poisoning, and the toxic ingredients contained in it can cause skin cancer. There are also some users who have serious skin damage at the rubbing place, leaving dark spots and scars that are difficult to heal, and the rebound rate is high. The compound preparation of pure Chinese herbal medicine for freckle removal is recognized as one of the safest and most effective methods of freckle removal, and is also highly recommended by dermatologists.
