What are the causes of stains and how to deal with them? Tips for reviewing skin care and eating habits

Blemishes are one of the causes that make you look older than you really are. Spots can be caused by a variety of causes, including lifestyle problems, incorrect skin care, and UV rays. Deal with the causes of blemishes and keep your skin clear. Here, we will introduce in detail the causes of stains and countermeasures.

First, let’s take a closer look at the causes of stains.

Accumulation of melanin by ultraviolet rays

The true identity of the stain is the deposition of melanin on the skin, which has increased due to the effects of ultraviolet rays. When exposed to ultraviolet rays, a large amount of melanin is produced from melanocytes. Melanin is excreted by turnover, but if a large amount of melanin is produced due to continuous exposure to ultraviolet rays, the excretion cannot keep up.

stress

Active oxygen generated by stress stimulates melanocytes to promote the production of melanin. In addition, stress is one of the major causes of stains, such as stimulating the production of melanin by disturbing the hormone balance.

Disturbance of turnover

Melanin is naturally excreted by turnover, but if the turnover cycle is disturbed, melanin excretion will be delayed. Causes of disrupted turnover cycles include lack of sleep, malnutrition, and stress.

Pigmentation after insect bites

Melanin is produced when the skin is inflamed by an insect bite. When the inflammation becomes stronger by stimulating the place where the insect bites, a large amount of melanin is produced and after the inflammation has subsided, it is deposited on the skin.

Let’s take a closer look at how to prevent blemishes with skin care.

Correct skin care

The production of melanin becomes active due to irritation and friction caused by cosmetics that are not suitable for the skin. Staining is more likely to occur if you scrub your skin with cleansing or washing pigments that have strong detergency, or if you use moisturizing cosmetics that have strong irritation.

In addition, if moisturizing care is not taken after washing the face, the skin becomes dry and the barrier function deteriorates, resulting in active production of melanin. Choose a cleanser that suits your makeup and skin type. When washing your face, lather the cleanser firmly and wash it carefully with the pad of your finger.

For moisturizing care, use lotion, serum, milky lotion, and cream in that order. Toner has the role of replenishing water. Rehydrate and oil with a milky lotion and layer the cream on areas that tend to dry out.

Thorough UV care to protect your skin from UV rays

Thorough UV care is important to protect your skin from UV rays. In addition to sunscreen, take all possible measures with parasols, sunglasses, arm covers, and underwear with UV protection. For sunscreen, check the SPF and PA values ​​and select the one that suits your time and destination.

SPF10 ~ 20, PA ++ for daily life such as walking and shopping, SPF20 ~ 30, PA ++ ~ +++ for outdoor light sports and leisure, SPF30 ~ 50+, PA ++ ~ for leisure and marine sports under the scorching sun ++++ is recommended.

Use items containing whitening active ingredients

In daily skin care, it is important to use items containing whitening cosmetological ingredients that promote the reduction of melanin and suppress the production of melanin.

-Vitamin C derivatives This
ingredient improves the absorption and stability of vitamin C and works as vitamin C when it penetrates the skin. In addition to promoting the reduction of melanin, it also works to lighten dark spots.

・ Arbutin A
component that suppresses the production of melanin by preventing the binding of tyrosine and tyrosinase.

・ Camomila ET
It is a component that suppresses the production of melanin by suppressing the activation and proliferation of melanocytes.

・ Tranexamic acid A
component that suppresses the production of melanin by suppressing the activation of melanocytes. In medicine, it is used as a medicine to suppress inflammation and stop bleeding.

・ Placenta extract
An extract derived from the placenta of animals, which has the function of suppressing the production of melanin.

・ Kojic acid
Kojic acid is produced by the Koji bacterium contained in the koji that is produced during the manufacturing process of sake and soy sauce. It works by inhibiting the action of tyrosinase, which is necessary for the production of melanin.

Food also contains ingredients that help prevent stains. Let’s take a closer look at the recommended foods to prevent stains.

Vitamin A

Vitamin A is a component that enhances melanin excretion by promoting skin turnover. It is abundant in eel, chicken liver, carrot, spinach, garlic, and Japanese mustard spinach.

Vitamin E

Vitamin E is a component that promotes blood circulation, supports skin turnover, and suppresses active oxygen by antioxidant action. It is abundant in almonds, avocados, eels and salmon.

Vitamin C

Vitamin C is a component that suppresses the deposition of melanin on the skin and promotes the reduction of melanin. It is abundant in lemons, kiwis, strawberries, paprika and cherry tomatoes.

protein

It is important to take protein consciously because it is a material that makes the skin. It is abundant in red meat, fish, eggs and tofu.

zinc

Zinc is a component involved in protein synthesis and gene expression. Take it consciously to arrange the turnover. It is abundant in almonds, oysters, beef shoulder loin, and eggs.
