Photorejuvenation has always been known as a "panacea" in the field of medical beauty. It has a wide range of functions, covering whitening, fading red blood streaks, skin rejuvenation, anti-aging and many other aspects. However, when facing some complex skin problems, the effect of photorejuvenation may be limited to a certain extent. Therefore, combining photorejuvenation with other medical beauty projects can solve the problem more accurately and exert greater efficacy.

Photon rejuvenation, also known as intense pulsed light technology, is essentially a special kind of light. Compared with ordinary sunlight, photon rejuvenation equipment filters out harmful ultraviolet rays and most infrared rays, retaining the wavelength range of 400 to 1200 nanometers. This specific wavelength of light can play a corresponding therapeutic effect according to different skin problems.

2、Specific effects of photorejuvenation

Lighten spots and brighten skin tone: Photorejuvenation has selective photothermal effect. Similar to two pieces of paper of different colors (one white and one black), under the same lighting conditions, the black paper will absorb more heat. Similarly, the pigment particles on the superficial surface of the skin will instantly explode and decompose after absorbing photon energy. With the metabolism of the skin, these exploded pigment particles will form scabs and eventually fall off, thus achieving the effect of lightening spots and brightening skin color.

Reduce skin sensitivity: Oxidized hemoglobin in blood vessels can absorb photon energy and convert it into heat energy. This heat energy will be transmitted to the endothelial cells of the blood vessels, causing the dilated capillaries to gradually close. Therefore, photorejuvenation has a certain improvement effect on skin redness problems such as red blood streaks, sensitive skin, and red acne marks, and can slightly reduce the sensitivity of the skin.

Skin rejuvenation and pore shrinkage: When photorejuvenation acts on skin tissue, it will produce photothermal and photochemical effects. When the skin is exposed to photons, the skin's self-repair mechanism will be activated, prompting the collagen fibers and elastic fibers in the deep layers of the skin to rearrange. This process can not only improve fine lines, but also make the pores more delicate, thereby achieving the effect of skin rejuvenation.

Photorejuvenation can effectively achieve the effects of lightening, skin rejuvenation and anti-aging by irradiating the skin with specific broad-spectrum light and using selective photothermal effect. However, the photothermal principle of photorejuvenation will cause the skin to absorb a large amount of water during the treatment, which enhances the skin's absorption capacity. Therefore, after photorejuvenation treatment, the skin needs to be replenished with water and nutrients in time.

Water-light needle adopts mesotherapy, which opens the skin channels and directly transports nutrients to the deep subcutaneous tissue to provide deep nourishment for the skin. After the photoelectric project, water-light needle can help the skin recover quickly and replenish the required nutrients.

Note: If you perform photorejuvenation treatment first, it is recommended to perform water-light needle treatment after the redness of the photons fades and stabilizes (usually on the same day); if you perform water-light needle treatment first, it is recommended to wait for more than 1 week before performing photorejuvenation. This is because the thermal effect produced by photorejuvenation may accelerate the decomposition of the hyaluronic acid component in the water-light needle, thereby affecting the therapeutic effect of the water-light needle.

Acid peeling is a common skin treatment method that uses high concentrations of fruit acid or salicylic acid to peel off the skin's stratum corneum, causing the aging stratum corneum to fall off and accelerate the renewal rate of the upper epidermal cells. This method can effectively treat acne, fade acne marks, shrink pores, brighten skin tone, and improve fine wrinkles.

However, erythema may appear on the skin after acid peeling, and the erythema subsides slowly. Photorejuvenation has significant advantages in reducing redness. The thermal effect it produces can kill acne bacteria, accelerate the disappearance of inflammation, and effectively solve skin redness problems such as red blood streaks, sensitive skin, rosacea, and red acne marks. In addition, photorejuvenation can also promote the growth of collagen. When used in combination with acid peeling, it can peel off the aging keratin on the surface, making the skin smoother and firmer, and improving the overall skin condition.

Photon rejuvenation has a good therapeutic effect on superficial pigmentation such as freckles and sun spots, but its range of action is mainly concentrated in the superficial layer of the skin. In contrast, picosecond laser is an ultra-short pulse laser with a pulse width at the picosecond level (1 picosecond = 10^-12 seconds). It uses the principle of light explosion and acts on the epidermis and dermis through ultra-pulsed lasers, causing the pigment particles inside the skin to explode instantly. The exploded pigment particles will be engulfed by the macrophages in the body and metabolized and excreted, thus achieving the effect of lightening, removing spots and whitening.

The combination of photorejuvenation and picosecond laser can be said to complement each other, especially for patients with severe pigmentation. This combination can not only effectively improve skin blemishes, but also even out skin tone and improve overall skin texture.

Notes: If you perform photorejuvenation treatment first, it is recommended to wait 2 weeks before performing picosecond laser treatment; if you perform picosecond laser treatment first, it is recommended to wait at least 1 month, and wait until the skin is fully recovered before performing photorejuvenation treatment, as scabs may appear on the skin.
