Is it harmful to the skin if you use too much skin care products? Have you corrected this skin care concept?

The norm for a dirt-poor girl is that the blogger says this product has a particularly good whitening effect. The Earth-Eating Girl: Buy it. Then another blogger said that this product has particularly good anti-aging effects. The Earth-Eating Girl: Buy it. Without realizing it, I bought a lot of skin care products. The point is that young girls will stack and use skin care products of various functions and brands, which greatly increases the chance of having a rotten face! So how should we use the various skin care products we buy?

Xiaona is my good friend. She uses skin care products from big brands, including Estee Lauder, Lancome and Olay. However, despite using such good skin care products, her face ended up in a mess. It's unbelievable. Before, I always thought that as long as it was a big brand product, there would be no problem.

Later it was proved that there was indeed no problem with the products produced by big brands or large factories. The root of the problem was mainly that big brands always thought that we must use a single product, so they did not think about the adverse consequences of using various skin care products in combination.

When big brands test product safety, they often conduct high-dose tests on a single product in a relatively short period of time. Sometimes they even use patches to seal the skin care products on the skin surface for more than 48 hours - only those that pass the test will be released.

However, this test is often performed on body skin with intact barrier function (such as the back), and is not mixed with other products for testing - RoC will not be included when testing the little green bottle.

Even large manufacturers cannot guarantee that there will be no problems under the following conditions:

(1) The skin on your face goes through the process of cleansing - care - sun protection - makeup - touch-up - makeup removal - cleansing - care - night powder every day. In fact, it has become very fragile, which is very different from the health of the skin on your back.

(2) The key point is that we usually use different products from different manufacturers on our fragile facial skin at the same time.

Therefore, we must abandon the old idea that as long as the skin care products are safe, they can be used together.

Why can't they be mixed?

Because there are too many products to use on the face, the steps are too complicated, and the situations are too changeable.

To use an analogy, the skin is a city, which is originally in order.

Due to the use of a large number of products, including makeup and skin care, the city's defenses have begun to decline, the interior has become somewhat unstable, and there are all kinds of potential problems.

At this time, for various purposes, such as whitening, anti-wrinkle, and soothing, we continue to send messengers to this city - [Niacinamide], [Retinol], [Dipotassium Glycyrrhizinate], [Bifida Saccharomyces Fermentation Lysate], and so on. The people in this city are able to receive this information and respond.

However, if there are too many messengers at one time and the information they convey is inconsistent, then the city may activate the emergency mechanism - a state of combat readiness - due to the arrival of these messengers.

This state of readiness may be the various symptoms of sensitive skin - redness, heat, even itching and stinging. Red blood streaks may also appear as a result. In the worst case, chloasma may also appear.

This is the principle, what are the specific methods?

Method plus instance

For purely moisturizing and sunscreen products, layering them is fine as long as your skin doesn't feel stuffy.

For products containing "messengers" (such as [niacinamide], [retinoic acid], [spore lysate of bifid yeast fermentation broth]), as long as they exceed a certain concentration, try not to stack them within one or two months.

For example, if you are using a small green bottle with a high content of [niacinamide] and are also using [Retinol], then don't add [Pro-Xylane] with it.

In addition, if you want to see the effects of the product continuously, it is recommended to use it for six months. Because even if you take tranexamic acid orally or even get a whitening injection, it will take several months to take effect, let alone just applying it on your skin?

If you want to increase your concentration during these six months, you can. For example, if you feel that the niacinamide you used before is not producing better results, you can increase the concentration of niacinamide appropriately.

If you want to change to a product with different functions, you should use this new "messenger" product alone first, and do not use other "messengers" for the time being. If you feel there is no problem after a week, you can add another "messenger" that you are used to. After another week, when you have basically adapted to it, you can switch to the new product.

Of course, the simplest and most direct method is to directly use a certain company's supporting products. In this way, there will basically be no major risks.
