Lying in the whitening cabin, you may only gain a short fake white

As the saying goes, one white covers one hundred ugliness, and the sunshine in winter is not as strong as in summer.

In this regard, Li Jing, director and chief physician of the Medical Beauty Department of the Affiliated Hospital of Tianjin Academy of Traditional Chinese Medicine, clearly stated in an interview with a reporter from Science and Technology Daily that the whitening cabins currently used in major beauty institutions only use the photochemical effect of LED red light.

LED red light has a photochemical effect on the skin

The whitening cabin sounds full of technology at first glance

Merchants claim that the principle of the whitening cabin is to use a cold light 655 nanometer light source with a whitening agent to stimulate blood circulation through light waves, accelerate epidermal melanin metabolism, inhibit the production of melanocytes, and achieve the effect of whitening and rejuvenating skin

"LEDs are light-emitting diodes, which are very common light-emitting devices in our daily lives

LED red light has a wide range of clinical applications in dermatology and other disciplines

Whitening cabin fast "whitening" hidden mystery

At present, LED red light is commonly used in the clinical treatment of skin beauty for two diseases, one is chloasma, and the other is post-inflammatory hyperpigmentation after laser surgery

"LED red light is rarely used clinically to whiten normal skin because its whitening effect on normal skin is limited

For many people, they have personally witnessed that after the "treatment" of the whitening cabin, the skin will be visibly white.

It is understood that the whitening cabins of merchants generally allow consumers to apply a so-called "moisturizing cream" on their entire body before entering the warehouse.

Li Jing introduced that titanium dioxide is an inorganic substance, non-toxic, has the best opacity, best whiteness and brightness, and is considered the whitest substance in the world today

Before entering the cabin, consumers are covered with a cream containing titanium dioxide.

Gong can become "Snow White" in peacetime

Not only whitening cabins, but also large rows of lights, spectrometers and other products appear on the Internet, and businesses also claim that they can be irradiated for whitening

According to reports, clinically, the more common whitening treatments are mainly photorejuvenation and laser skin rejuvenation and whitening

Li Jing emphasized that these two treatments require very professional lasers and strong pulsed light to achieve results.

In addition to photoelectric whitening, Li Jing suggested that some skin care products with whitening effects should also be used at home to achieve the best effect

"However, the addition of these substances will be strictly in accordance with a certain ratio, because the concentration is too high, it will irritate the skin
.
Therefore, the content of these substances in cosmetics will not be too high, and it takes a lot of skin care to achieve the whitening effect
.
" Li Jing said
.

Finally, Li Jing emphasized that no whitening method can achieve immediate results.
If you want to have fair skin, you need to cooperate with good living habits, such as not staying up late, paying attention to moisturizing, paying attention to sun protection and so on.
