After reading the professional dermatologist's vomit, I found that I knew nothing.

When I was surfing the Internet recently, I found that a YouTube channel called "Dr Dray" suddenly became popular, and everyone was discussing this newly discovered treasure skin care blogger.

This treasure girl's name is Andrea. She is a licensed dermatologist in Denver, USA (she can be regarded as an attending physician in a domestic 3A hospital).

At present, there are 11W fans on YouTube, and many videos have more than one million hits. When analyzing skin care products, she not only talks about the efficacy of ingredients, but also gives suggestions based on professional knowledge and experimental papers.

Most of the recommended products are effective and inexpensive cosmeceuticals, so there is a tendency to become the queen of goods recently.

but-! Just when I thought that, Andrea suddenly made a big deal out of common sense. Everyone else shares the annual favorite and empty bottle, and she shares the bad skin care trend next year.

today, I will take stock of the professional dermatologist's views on various skin care trends in 22, and then give some practical suggestions. In 221, none of us will step on the thunder!

If you feel the same way, don't forget to watch it

Sometimes I really feel that the world is very small, and if you don't rub "mud" on your skin, you think it is an effective cleaning method. How can it be unified all over the world?

first, a group of vicious people on TIKTOK (foreign version of Tik Tok) "rubbed their blackheads with their bare hands"

and then, a little X book in Tik Tok, China "taught you to exfoliate".

The visual effect is quite bluffing, but it is actually a lonely feeling.

First of all, people's blackheads are not that big. Secondly, blackheads are the result of sebum oxidation. When taken out, the top is black and the tail is white. It's not exactly the same as those so-called blackheads in the video, at least it's irrelevant.

In addition, some ingredients in the product have their own mud rubbing effect, such as macromolecular hyaluronic acid and carbomer xanthan gum.

don't get me wrong, Andrea doesn't mean that cleaning products are useless. Using clay mask alone does have a certain effect of absorbing oil and blackheads, but frequent "rubbing" of the skin will only aggravate acne or acne symptoms.

With the flourishing of skin care brands in recent years, many people have realized that the beauty market is a good cake, so all kinds of stars have come to join in.

plus their own traffic, they directly saved a lot of publicity expenses for the marketing department.

But in the video, Andrea mercilessly poked the filter bubbles that the stars brought with them and told the fans whether the truth was true or not:

Professional R&D personnel of stars

Stars bring salt to their products. Are stars really using

Let's talk first

Is there such a thing as anti-pollution skin care products? No!

is it necessary to fight pollution? Yes!

the so-called anti-pollution is not a gimmick, because it is often small things that hurt our skin that we don't pay attention to in life.

Many studies show that particulate matter such as PM2.5 in the air can not only settle on the skin surface, but also penetrate into the deep dermis, which is easy to cause allergies and inflammation. Cooking fumes and ultraviolet rays in the sun will also double kill our skin.

But at present, there are no real anti-pollution products and technologies, so we can only temporarily use some products containing VC, green tea polyphenols, and adibenzene to alleviate the harm of free radicals to the skin.

besides, Andrea said that she thinks it is the most reliable at present &; The real solution is to clean the sun well. If you need to be exposed to the outdoor air with very poor air quality for a long time, you can even use physical protection means such as a mask.

What's wrong with a facial massager? It's just that you have to spend a lot of money to add a dusty ornament to the dressing table.

No matter how bad it is, you can comfort yourself that at least you have the same style as Hua Fei and Ruyi\'s Royal Love in the Palace.

So Andrea didn't kill them with a stick, saying that these massagers can really help people relax (such as massaging lymph nodes in the neck).

It can also help to eliminate edema when it swells like a freshly steamed steamed bun in the morning. But don't count on it for advanced skills like anti-aging, he is still a child.

You know, the aging of our face is caused by fat loss/collagen damage/bone loss and other factors.

These roller-shaped instruments can neither help us to replenish the lost fat nor repair the damaged collagen. After using them, except that the arm muscles are stronger, what should our face look like?

is it delicious to have this money for medical treatment?

dermatologists suggest that you should know these things before you do photon rejuvenation and hot Maggie.

In the whole year of last year, powdery VC products were fired on various platforms and purchasing friends. Many people praise it for its immediate whitening effect, which is simply a human bleach.

A can of several tens of dollars can also be mixed with different skin care products, and it seems that if you don't buy it, you will regret it for life.

However, VC itself is a very unstable ingredient, and various brands try their best to keep its activity, leaving a large number of researchers bald.

vacuum pump and brown bottle have been tried all over, and no one dares to say that the activity of their own VC products can be maintained from beginning to end. Not to mention this powdery prototype VC, which will disperse when the wind blows, and can't wait for it to take effect.

Moreover, VC is more easily absorbed in a low pH environment. Adding it to skin care products will only let you know what is the happiness of cement mixers.

Moreover, some mainstream high-concentration VC products have reached the peak by adding 2%. No matter how high the concentration is, it is not skin care, but a bad face.

Therefore, when you buy products, you must be alert to the "componentism"&; "Concentration theory", regardless of skin feeling and formula, products that only talk about ingredients are hooligans!

after talking about high concentration VC, let's talk about high concentration nicotinamide by the way.

Andrea thinks that the worst skin care concept last year was the concentration competition of nicotinamide. Some brands think it's sunny and the rain has stopped, and it's fine again. When the product nicotinamide was launched, it directly skipped the mainstream concentration of 5% and 1% on the market and came to 2% at one go.

Although nicotinamide is a good thing, it can help diminish inflammation and calm down, and improve new acne marks and pigmentation. However, the concentration of nicotinamide above 2% can already play a good skin care effect. From the point of view of skin absorption rate, it is not a linear increase if it exceeds 5%.

The efficacy of 2% nicotinamide is not necessarily four times that of 5%, but the damage to skin is likely to be more than four times!

Probably with the rise of various component parties in the skin care circle, many manufacturers think that as long as the concentration is piled high enough, people will buy it, which is actually another disguised IQ tax.

To say that the trend of ingredient skin care in last year's fire was more than "early C and late A", CBD, a new darling of skin care, should also have a name.

the full name of CBD is cannabidiol, and its scientific name is "cannabidiol", so it is also called cannabis skin care, but it is not the same as recreational cannabis that makes people mentally dependent and addicted.

In 215, the former China Food and Drug Administration (CFDA) included "CANNABIS SATIVA LEAF EXTRACT" in the Catalogue of Used Cosmetic Raw Materials in China, allowing the use of cannabis leaf extract in cosmetics.

In 217, the World Health Organization also made it clear that there is no health risk or abuse in CBD.

Many skin care bloggers say that CBD has a very good anti-inflammatory effect, and can even be used for skin diseases such as eczema and acne, and it is a better antioxidant than VC or VE.

But Andrea, as a dermatologist, doesn't believe this marketing talk, because there is no standard clinical dose experiment in CBD at present, and no one knows how much concentration of ingredients can take effect on the skin, even the side effects are in? The state of.

personally, I think, firstly, the standards of cannabis ingredients that can be added to skin care products in China and abroad are different, and secondly, many bloggers do compare their own before and after use, praising CBD ingredients to some extent.

So for CBD, a relatively new ingredient, you can let the bullet fly for a while, wait and see its reputation, and then make a choice later.

how about it? How many of the 7 bad skin care trends have you accidentally stepped on? (If you don't win any of them, it's worth showing off in the comments.)

In fact, I hope everyone can start from their own needs and skin quality when buying products, and don't get carried away by marketing. Rational shopping, rational skin care.

It's like the coming spring. Compared with thick and sticky face cream, I still use refreshing water emulsion &; Sunscreen is more suitable

Last but not least, I will look at it from the point of view &; One person was randomly selected from the comments, and online celebrity in the beauty circle and Raduli Blush with rows of faces placed on the dressing table were sent out!

at 19: on March 11th, I organized a confession game on the video number. I had a hunch that the scene would be very exciting, and I was waiting for you. Remember to set the alarm clock!
