Ladies who love beauty, do you know how to choose products to lighten spots?

The Goddess Festival has just passed. I believe that many young ladies have stocked up a lot of their favorite skin care products, such as concealer, spot lightener, sunscreen, etc. Of course, many young ladies who have time must be frequent customers of beauty and skin care stores. It is no longer impossible to love beauty and become beautiful. It’s just that the effects of concealer and sunscreen can be seen quickly, but for spot lightening products, many young ladies may have many doubts, such as do spot lightening products really work? What is the principle of spot lightening? After all, they are bought with hard-earned money, and they are used on their own faces that they have guarded for a long time. So it is normal to have doubts. So today I will talk to you about the purchase precautions of spot lightening products from three aspects.

First of all, it is strongly recommended that you read the product manual carefully.

Whether a spot-lightening product is effective or not is not determined by the four words “spot-lightening product”, but by the mechanism of how the ingredients work behind it.

Often, people only focus on the "product name" and therefore treat all freckle products as the same product. As a result, some people confidently say that freckle products are ineffective, while others are very confident that freckle products are effective based on their experience. If you look closely, you will find that both people are not using the same product, and the ingredients behind them are different, so naturally, there is no way to talk about the effect.

Therefore, when buying freckle-removing products, you must pay attention to the specific ingredients.

A common ingredient in freckle products is 377, or phenylethyl resorcinol, which works by inhibiting the activity of tyrosinase that produces melanin. However, if the concentration is too high, it can easily irritate the skin and stimulate the production of melanin, so the concentration in 377 products is critical.

Another common ingredient in spot-lightening products is niacinamide, which is a biological ingredient and has been widely used in spot-lightening products in recent years. Its mechanism of action is to inhibit melanosome transport. However, the problem is that if it is discontinued, melanosome transport will resume, resulting in a rebound.

It can be said that the objective shortcomings of these two ingredients themselves have caused many people to have doubts about freckle-removing products, and there is also considerable controversy.

As mentioned above, is there really no solution to lightening spots?

Not necessarily. In fact, we need to understand the deep biological mechanism of the pigmentation itself, and then solve it in a targeted manner, and we can ultimately fight against the pigmentation.

Secondly, the causes of pigmentation

Pigment spots are mainly formed by the accumulation of melanin, so why does melanin accumulate on the skin? In fact, this is a protective mechanism.

For example, under strong ultraviolet rays, the human body is easily damaged. At this time, the melanocytes in the skin will start the defense mechanism and begin to secrete melanin to help the human body relieve the stimulation and damage of ultraviolet rays. However, the side effect is that the skin color darkens, so everyone will notice that people who are exposed to too much sunlight are prone to darker skin color, and in severe cases, spots will appear.

So some people may ask, why do I still have spots even though I have done a good job of sun protection?

This is another mechanism of pigmentation that is often overlooked: damaged skin barrier.

Excessive skin care is a common problem in the skin care industry today. Some whitening products go beyond the requirements of use in pursuit of results, such as excessive acid application or high concentrations of niacinamide. If the damage to the skin caused by these ingredients exceeds the skin's ability to repair, the skin barrier will be damaged. Skin damage will have two effects. On the one hand, melanin will gather at these locations to form spots. What's more troublesome is that skin damage itself will stimulate the production of melanin. Damaged skin will release regulatory factors such as leukotrienes, which act on melanocytes, resulting in the secretion of melanin, and then spots will appear.

It can be seen that the formation of skin spots is the result of ultraviolet radiation and damaged skin barrier. Therefore, a good spot-lightening product must solve the spot problem from these two aspects.

Finally, how to solve the spots

Of course, it is not easy to solve the problem of pigmentation. Usually only first-class skin care companies have the research and development capabilities to solve it. Basically, it is divided into two steps. Here is a brief explanation of the principle.

Step 1: Target melanin

To lighten spots, first target melanin and allow the product to work at different levels of the skin.

On the surface of the skin, it does not provide a "breeding ground" for the growth of melanin; on the middle layer of the skin, it accelerates the removal of melanin and blocks the transportation of melanin; and on the bottom layer of the skin, it can inhibit the deposition of melanin.

Step 2: Whitening

At this point, I believe that many people have a better understanding of blemish-lightening products. Skin pigmentation itself is not only affected by ultraviolet stimulation, but also related to damaged skin barrier. Therefore, blemish-lightening products must solve the pigmentation problem from these two aspects and finally achieve skin whitening.

However, a friendly reminder is that skin care should be done in a timely manner, but be careful not to overdo it.
