Are LED beauty masks useful? Decryption of the principle of LED spectrometer-Beijing Zhenhuimei Beauty Equipment Co., Ltd.

LED facial masks, , LED spectrometers, and various LED beauty equipment have sprung up like mushrooms in recent years. But it is not used for lighting, but is used by major beauty equipment manufacturers to illuminate the face. I thought it was not very hot in the market, but recently it seems that due to the hype of variety shows, many beauty influencers, and a large number of advertisements, some beauty salons claim that "just wearing an LED beauty mask for 10 minutes a day can effectively improve the skin. skin condition," or advertise the efficacy of treating acne, but is it really so miraculous?

Let's take a closer look at the truth of this product from the beginning!

What are the functions of LED beauty mask and spectrometer? Let’s take a look at how beauty equipment manufacturers advertise

Each product often requires a certain technology or principle, and through the packaging of this matter, the credibility of the product's effect can be improved. This practice is very common, and most netizens should have encountered such experience, and the manufacturers of this type of beauty equipment are no exception. Let's take a screenshot of a few related pictures found on the Internet to see how it is claimed.

• Red light with a wavelength of 630nm can stimulate the proliferation of collagen and elastin, activate fibroblasts, promote blood circulation, anti-inflammation, and accelerate wound healing.

• Yellow light with a wavelength of 590nm can promote melanin metabolism, brighten skin tone, soothe sensitive skin, and improve skin's absorption of skin care products.

• Blue light with a wavelength of 415nm can inhibit the growth of bacilli, reduce the secretion of skin sebaceous glands, and improve acne and pimples.

Is the claim of LED beauty mask and LED spectrometer justified?
As a matter of fact, many of these beauty devices are based on relevant medical research, so that  feel that this is an opportunity or direction, so they quickly launched such products. In some studies, it has been pointed out that light exposure is really helpful in the treatment of acne.

The theoretical basis that blue light and red light can be used to help treat acne comes from the fact that acne bacteria that cause acne will synthesize endogenous rhodopsin, and visible light with a wavelength of 400-700nm will be absorbed by endogenous rhodopsin, resulting in endogenous rhodopsin Activation, and then produce some free radicals, leading to the death of acne bacteria. The study found that this effect is most obvious when the wavelength is 410nm, and the effect of blue light is also better than that of red light. However, red light has a longer wavelength and can penetrate deeper into the skin, so it is also used. In some legitimate medical institutions, blue light or red light is sometimes used for acne treatment, but it does not mean that you should buy a  can achieve the same effect when used at home. Usually, it is combined with external medicine to inhibit bacterial reproduction and inflammation.

Are LED beauty masks and LED spectrometers really so effective and safe?
Those who have seen the red light and blue light  used in beauty parlors will find that they are usually better than those on the market. The ones you can buy for home use are much bigger. In fact, as long as this kind of household spectrometer products do not claim medical efficacy, they are positioned as general household appliances, just like buying hair dryers and electric fans.
Then the problem comes. What is the power of these instruments? Is the output power stable enough? This involves whether the use of such products will burn or irritate the skin. If these light sources touch the eyes so closely, will they cause damage to vision without relevant protective measures?

You know, acne is a disease caused by multiple factors, and acne bacillus infection is only one of the links. Even if blue light irradiation is effective, can a good therapeutic effect be achieved with just one step of treatment? Then why do we need doctors, doctors and other staff? Thinking about it in another direction, if you spend a few hundred yuan at home, you can buy a lighting device that will be effective. Then beauty salons spend tens of thousands of dollars to buy medical-grade photoelectric equipment. Are these beauty salons stupid? Just buy a few hundred yuan and let you play it. Isn’t it time-saving and labor-saving~
