With its many advantages such as non-invasiveness, gentleness, effectiveness, and wide application range, photorejuvenation has always occupied its own place in the medical beauty circle where products and instruments emerge in an endless stream.
In clinical practice, I believe that many friends have encountered patients who reported that the energy was too low and they did not feel anything at all, and if they did not feel anything, there was no effect, so they asked the doctor to increase the energy parameters.
Is it true that the higher the energy of IPL photorejuvenation, the more painful the experience, and the better the effect? Let’s discuss it together~
Principle of photorejuvenation.
Photorejuvenation, also known as intense pulsed light (IPL) treatment, works on the principle of selective photothermal action. Light energy of different wavelengths is absorbed by different color bases in the skin, such as melanin, hemoglobin, etc. When light energy is converted into heat energy, the tissues where these color bases are located may be damaged to a certain extent, thereby stimulating the skin’s repair process, promoting the regeneration and rearrangement of collagen, and achieving the effect of skin rejuvenation.
The wavelength of intense pulsed light for photorejuvenation is in the band range of 500~1200nm. The wavelength and intensity are different, and the effect is also different. At present, the super photons we often talk about on the market are upgraded versions of photons. After continuous iteration and upgrading, M22 has now developed to the latest generation of the seventh generation AOPT super photons.
Photon skin rejuvenation machine.
The photorejuvenation treatment machine is called IPL.
IPL is short for intense light, also known as photons and intense pulsed light. It is an intense pulsed light released by a high-energy xenon flash lamp under the action of tens of thousands of volts of high voltage. It consists of incoherent, non-parallel broad-spectrum light, and the wavelength is usually 400-1200nm. Photons are mainly used to treat skin aging. In addition, they are also widely used to treat pigmented skin diseases, vascular skin diseases, hirsutism and even inflammatory skin diseases (such as acne and rosacea).
Like lasers, the mechanism of action of IPL is also based on the principle of selective photothermalysis. There are many target chromophores in the skin, such as melanin, hemoglobin and water. Different target chromophores have different levels of light absorption: melanin absorbs less light as the wavelength increases in the range of 290-1200nm; hemoglobin has three absorption peaks at 418nm, 542nm and 577nm; the absorption spectrum of water is mainly in the near-infrared band.
As a broad-spectrum light, IPL has a wavelength range that basically covers the main absorption peaks of the above-mentioned target chromophores. Therefore, the wavelength that is more easily absorbed by the target chromophore is selected through the filter, and the pulse width is adjusted to be shorter than the thermal relaxation time of the target chromophore. With sufficient energy, reasonable pulse intervals and synchronous cooling, it can effectively and safely destroy skin lesions and achieve the purpose of cosmetic treatment.
Intense pulsed light therapy devices can also be used as professional medical equipment for the treatment of skin diseases and skin beauty in medical institutions such as dermatology, plastic surgery, and medical beauty centers.
What problems can photorejuvenation be used to solve?
Improve skin texture and color.
Stimulate the regeneration of skin collagen to make the skin firmer and more elastic. At the same time, it can decompose pigments, reduce spots, and improve skin color.
Reduce fine lines and wrinkles.
Enhance the elasticity and luster of the skin, thereby reducing mild wrinkles and fine lines. For deeper wrinkles, photorejuvenation can also play a certain role in alleviating.
Remove acne and acne marks.
Inhibit inflammatory reactions, reduce the occurrence of acne and the residue of acne marks. For acne and acne marks that have already formed, it can promote skin repair and regeneration, so that they are gradually improved or eliminated.
Enhance skin elasticity and luster.
Stimulate the regeneration of collagen, enhance the elasticity and luster of the skin. At the same time, it can also promote skin metabolism and accelerate the renewal of skin cells.
There is a study to explore the value of photorejuvenation technology in the clinical application of skin beauty. 87 patients treated with photorejuvenation technology were selected as the research subjects. According to the different conditions of the patients’ skin, they were divided into group A, group B and group C, with 29 cases in each group. The patients in group A mainly had facial spots, the patients in group B mainly had relatively large pores, and the patients in group C had dilated capillaries. The three groups of patients were treated with photorejuvenation technology. The treatment effects and satisfaction of the three groups of patients were compared.

| Category | n | Significant effect | effective | invalid | Total effective |
| Group A | 29 | 14(28.28) | 14(28.28) | 1(3.44) | 28(96.56) |
| Group B | 29 | 13(44.83) | 15(51.72) | 1(3.45) | 28(96.55) |
| Group C | 29 | 15(51.72) | 14(28.28) | 0 | 29(100%) |
Data results show that the total effective rate of photorejuvenation is relatively high. However, as a maintenance project, the effect of photorejuvenation is difficult to measure with the naked eye.
Because some people who seek beauty will actively ask the doctor to increase the energy and “make it painful”, thinking that this will be effective.
Is this really the case?
Photorejuvenation effect VS energy.
Energy value is indeed a very important adjustment parameter in photorejuvenation. If the energy value is adjusted too low, the patient will not feel much during the experience and will not reach the end point reaction, and the effect will be greatly reduced.
However, if the energy value is too high, some people’s skin will not tolerate it, which will cause a certain burden on the skin, affect the later effects, and may also cause certain damage. Take melasma and sensitive skin as examples. This type of skin is already fragile and difficult to treat. If too high a treatment energy is given, it will only further aggravate the skin damage, and it is very likely to cause skin breakdown, cause darkening or aggravate inflammatory reactions.

| Mainly rough skin, fine wrinkles, and large pores | 640 | 3 | 3.0~6.0/20~35 | 18~25 | |
Of course, when different skin conditions are treated with photorejuvenation, the treatment endpoint reactions are different. For example, when treating acne and acne marks, the treatment endpoint reaction is that black acne marks become slightly red, and red acne marks become dark red. This is because melanin and hemoglobin in the skin selectively absorb specific bands and are then further destroyed. When treating pigmentation, the treatment endpoint reaction is that the color of the spots deepens, such as light-colored freckles will turn dark brown, and slight edema will occur around the spots. The most basic function of photons is skin rejuvenation. As long as the treatment is in place, you will find that the skin becomes brighter, finer, and more transparent after removing the gel.
In order to ensure the treatment effect and reduce the side effects of treatment, we need to choose different treatment paddles, pulse width, number of pulses, energy density, etc. according to different skin types.

Photorejuvenation treatment conclusion.
- Photorejuvenation does not mean the higher the energy, the better. You need to choose the appropriate energy according to the patient’s skin color, skin condition, and indications.
- During the operation, the spot test should be carried out according to the specifications, and the endpoint reaction should be observed and the energy parameters should be adjusted at any time. Avoid adverse reactions due to improper parameter settings.
- Multiple operations can accumulate therapeutic effects and make up for the poor therapeutic effects that may occur due to low energy.
- With the help of VISIA skin detector, you can show the treatment effect of photorejuvenation to the patient.
