What is a stain

A blemish is a condition in which the surface of the skin has partially changed from brown to black. There is no concept of size or shape. There are several types of age spots, and the three most common are age spots, melasma, and freckles. Age spots are the most common age spots. At first it was thin, but it has the characteristic of becoming darker with age. Melasma is a common blemish on women in their 30s and 40s. There is a feature that can be left and right symmetrical from the cheeks to the bottom of the corner of the eye. Freckles are a collection of small spots around the nose and cheeks. If a parent has freckles, it is possible that the child will also have freckles due to genetics.

Causes of blemishes

Causes of spots can be UV rays, pigmentation, and the effects of lifestyle habits. If you are worried about erasing stains, let's start by finding out what is the cause of creating stains. You may find something that works for you.

ultraviolet rays

Ultraviolet rays promote the production of melanin, the source of dark spots. When our skin is exposed to UV rays, it gets sunburned and darkens. This is the function of melanin, which blocks ultraviolet rays from reaching the dermis and protects them from damage. Skin cells are reborn with new cells every 28 days. The melanin produced by sunburn is also sloughed off along with the old cells. However, if you are exposed to UV rays for a long time or if you are exposed to strong UV rays, a lot of melanin is produced, so the excretion cannot keep up and it will remain on the skin as spots.


Pigmentation occurs when excess melanin is produced to protect the skin. Causes of pigmentation include inflammation such as acne and insect bites, tightness from underwear and belts, damage from razors and hair removal creams, and makeup residue. The color of the spots varies depending on the amount and depth of melanin that causes pigmentation. If the amount of melanin is small and pigmentation occurs in the shallow part of the skin, it looks light brown, and if the amount of melanin is large and pigmentation occurs in the deep part of the skin, it looks dark brown to black.

Due to body environment such as smoking, eating habits, and sleep

Daily habits affect wrinkles. For example smoking. Smoking worsens blood flow and increases active oxygen. Excessive active oxygen is the cause of rough skin, spots and wrinkles. In addition, diet and sleep are involved in the reincarnation (turnover) of the skin. If you don't get enough nutrition and rest, your hormones will be out of balance and your metabolism will slow down. It is necessary to arrange the turnover cycle so that melanin does not accumulate and become spots.

how to remove blemishes

When you want to erase blemishes, it is important to block the production of melanin and to discharge excess melanin. Specifically, it prevents UV rays and promotes skin turnover . Let me explain.

protect from UV rays

Use sun cream, parasols, hats, etc. to prevent unprotected exposure to UV rays. Even if spots have already formed, continued exposure to UV rays will increase the production of melanin, making the spots more difficult to disappear and causing new spots to form. Also, you need to be careful about the UV rays that come in through your eyes. Melanocyte cells that produce melanin are activated when they sense that UV light has entered. UV-blocking sunglasses are effective in preventing UV rays from entering your eyes.

Switch to cosmetics with more whitening ingredients

Let's incorporate cosmetics containing many whitening ingredients into skin care. By the function of whitening ingredients, we can expect suppression of melanin production, excretion of melanin, and lightening of the skin. Recently, whitening cosmetics for men are also on sale.・ Mechanism that inhibits melanin production Suppresses the activation of melanocytes (pigment cells) that produce melanin. Alternatively, it inhibits the action of the enzyme tyrosinase that is necessary to make melanin.

  • Mechanism that promotes melanin discharge By promoting skin turnover, it promotes melanin discharge.
  • Mechanism that promotes the lightening of melanin By reducing the oxidation reaction of melanin, it returns to the stage before melanin was produced and lightens the spots.
We will introduce typical whitening ingredients contained in cosmetics and their functions.

Moisturize well

Increase the barrier function of your skin by moisturizing it well. When the barrier function of the skin decreases due to dryness, it becomes more susceptible to damage when exposed to ultraviolet rays. UV rays and dry skin also affect the turnover cycle. Moisturizing care is important to expel melanin quickly. Hyaluronic acid, collagen, and ceramide are ingredients with high moisturizing effects. It would be even better if it was added to cosmetics together with the whitening ingredients introduced earlier.

review your eating habits

In order to suppress the action of active oxygen, try to eat foods containing antioxidants. Antioxidants include vitamins A, C, E, lycopene, polyphenols, L-cysteine, ellagic acid, and flavonoids .

get good quality sleep

Get a good night's sleep to improve the secretion of growth hormone. Growth hormone has the function of promoting skin turnover, and is secreted in large amounts during sleep. Growth hormone is secreted the most in deep sleep at the beginning of sleep. Therefore, it is important to get good quality sleep. In order to get a good quality sleep, before going to bed, avoid stimulating blue light from smartphones and TVs, dim the lighting in the room so as not to interfere with the secretion of melatonin, and expose yourself to sunlight when you wake up in the morning. So it's effective to reset the body clock.

How to remove stubborn stains

There may be some people who are worried that they have spots even though they are taking measures, or that the spots do not disappear even though they are taking good care of them. It is difficult to improve stains that have passed over time, and even if you use a commercially available whitening lotion, the stains may not disappear. If you want to erase stubborn spots, consider treatment at a cosmetic dermatologist or a clinic that specializes in spots.

Treat with cosmetic dermatology

The main blemish treatments performed by cosmetic dermatologists include laser/light treatment, oral treatment, and topical drug treatment. Laser/light therapy is a treatment that destroys the melanin that has accumulated in the skin by irradiating special lasers and light on spots, freckles, melasma, etc. In addition to blemishes, there are many other types of lasers that are effective in improving dullness, opening pores, and treating acne. Internal medicine treatment is a treatment that promotes the improvement of spots from within the body by taking ingredients that are effective against spots. In general, medicines with vitamins and anti-inflammatory ingredients are used. Topical drug treatment is a treatment method that applies a stain-removing cream that contains whitening ingredients. Since it takes a long time to improve spots with topical medicine alone, it may be used in combination with other treatments.
