Hello friends~
A while ago, everyone knows the "big earthquake" in the beauty instrument industry? Since the implementation of the new regulations in April, radio frequency products that have not obtained the medical device registration certificate can no longer be produced and sold.

Therefore, it is difficult for many small partners with anti-aging needs now, and there are very few radio frequency instruments on the market to choose from...
However, Jessica recently discovered a magical new technology while surfing the Internet - "transdermal collagen light", and I came to share it with you! It is said to be safe, effective and low in pain~
Many foreign media have reported on this new technology:

So, what is the new favorite "transdermal collagen light"? What is the difference between it and RF? Can it really be our new anti-aging method?
Let's take a look at the horn!
What is the difference between transdermal collagen light and radiofrequency technology?
Radiofrequency technology is relatively more familiar to everyone, and the principle is to put high-frequency electromagnetic waves into the deep tissues of the skin, so that the dermis is heated and activates collagen production.
Transdermal collagen light is a non-invasive skin treatment technique, similar to the milk light and red and blue light we talked about earlier, it works through the skin through specific wavelengths of light.
However, transdermal collagen light contains a wider range of red light bands, which combines near-infrared short waves (760-1400nm) and near-infrared long waves (1400-1940nm), and the penetration range can also range from the superficial dermis to the deep dermis.
It is precisely because of the different principles of the two that the advantages of transdermal collagen light are revealed:
Deeper effects
Depending on the design of the device, the depth of skin penetration can be different, but the depth of action is generally about 3.5mm.
Transdermal collagen light consists of two brothers, the near-infrared short-wave and the near-infrared long-wave, which work together to directly dry from the superficial dermis to the deep dermis, up to 4.5mm, which can activate all levels of dermal collagen production and bring more significant anti-aging effects.

Anti-aging through biological action
Radio frequency technology is relatively simple, relying on physical heating of the dermis to promote collagen production, and transdermal collagen light can bring magical biological effects in addition to photothermal effects~
In fact, low-energy near-infrared waves are also known as low-energy laser therapy (LLLT) in medicine, which is absorbed by the mitochondrial chromophore of skin cells, and after the cells are "dry", they can enhance enzyme activity, electron transmission, mitochondrial respiration and the production of adenosine triphosphate (ATP), which is more energetic.
Therefore, low-energy near-infrared waves can stimulate cell metabolism, wound healing, and relieve pain and inflammation [1].

Transdermal collagen light can resist skin aging caused by inflammation to a certain extent, and has a soothing and sedative effect.
Safer
Radiofrequency technology is to heat the dermis to "spur" collagen production, when the energy is too high or for a long time, it may damage the skin, I still remember when Jessica first came into contact with the radiofrequency instrument, she directly turned on the high-end, and her face was burned instantly... That's why temperature control is so important.
Transdermal collagen light is milder than radiofrequency technology, red light can directly penetrate the epidermis and act directly on the dermis, so there is no damage to the epidermis, no burns will occur, and in addition to the effect of heating, red light can also make cells "active" to activate and achieve anti-aging effect.
What are the skills of transdermal collagen light?
Before talking about skills, let me briefly introduce the principle:
Our skin can be divided into three layers: epidermis, dermis, and subcutaneous tissue. Different wavelengths of light can penetrate to different depths of our skin and "hit" different tissues in the skin, and the three main "targets" in the skin are pigment, blood vessels and water.

When a specific wavelength of light "hits" the corresponding "target", it will have an impact on the tissue and play an effective role~
Transdermal collagen light combines near-infrared short-wave (760-1400nm) and near-infrared long-wave (1400-1940nm), penetrating from the superficial dermis to the deep dermis, and the three "targets" are all not missed!

In this way, you can know at a glance that the skill range of transdermal collagen light is really wide and deep~
Promotes collagen synthesis
Near-infrared light is mainly absorbed by the moisture in the skin, and the moisture absorption energy will be converted into heat energy, and the collagen will shrink immediately when heated, so the use of transdermal collagen light can quickly see the skin tightening effect.
When the temperature, energy and time are sufficient, it will induce the production of new collagen~

Transdermal collagen light contains near-infrared short waves that penetrate deep into the skin, so it is mainly responsible for collagen regeneration in the deep dermis [3]; The main area of work of the NIR long wave is the superficial dermis, which pushes fibroblasts to resynthesize collagen and restore skin elasticity after being heated [4].
The two brothers complement each other, like a perfect construction team, working in the depths to fill in the "potholes" under the skin and lay a solid foundation;
One works from the superficial layer to smooth out the small fine lines on the surface, and the two together exert a significant anti-aging effect, making the skin firmer and plump.
The test report showed a significant improvement in facial wrinkles after only 7 sessions of using the transdermal collagen light device [5].
Oh yes! My nasolabial folds have finally been saved!

Skin whitening
When melanin and hemoglobin are "hit" by a specific wavelength of light, they can "disintegrate" on their own, playing a role in whitening and redness.
Especially the light with a wavelength of 1064nm is the best of the near-infrared short waves! It is very effective in removing melanin from the surface layer of the skin and can be used as a treatment for pigmented spots, melasma, and pigmentation [6].

Therefore, the use of transdermal collagen light can help us whiten the skin, brighten the complexion, improve facial pigmentation, and reduce redness to a certain extent.
Soothes and calms the skin
As mentioned above, transdermal collagen light can also exert a biological effect on the skin, by stimulating cell metabolism, repair and other reactions, playing a role in soothing and calming the skin.
At this moment, a lady with sensitive skin and redness is heartbroken!
In short, transdermal collagen light is fully capable of the basic work of anti-aging, completely surpassing the original radiofrequency technology, and also adds a buff for whitening and soothing the skin.

Can we ordinary people use it at home?
Having said all this, can transdermal collagen light enter our lives and become a new way to fight aging at home?
It shouldn't be too long to wait!
At present, similar technical principles have been applied in some medical aesthetic projects, such as the NIR milk light project, which selects near-infrared light in the 900~1800nm band, which has the effect of skin rejuvenation and whitening, and promotes collagen production.

The household transdermal collagen light instrument is being developed and tested, so it is not far from us~
However, having said this, Jessica still has to advise friends who have anti-aging needs not to be blindly moved.
First of all, although the anti-aging effect of transdermal collagen light technology has been proven, in order to truly exert the effect, the instrument needs to withstand the test.
Therefore, if you buy a transdermal collagen light beauty instrument, you must pay attention to whether the product is supported by scientific research.

Secondly, although the red light will be relatively mild, for the sake of safety, it is recommended that you understand your skin condition first, and consult a doctor if necessary to see if you are suitable for using this type of beauty device.
Finally, we still have to maintain reasonable expectations, no matter what anti-aging products, they need to be used for a long time in accordance with the specified frequency and time, remember to use it for ten minutes, and if you can't think of it, you can put it on the cabinet to fall dust, so it has no effect, and the skin may not be able to stand it...

OK, finally to summarize for you: transdermal collagen light can promote collagen synthesis, have the effect of tightening and lightening lines, and at the same time whiten and soothe the skin. Compared with RF technology, it also has its own unique advantages.
Recently, if you want to start with an anti-aging beauty device, you can look forward to the transdermal collagen light~
