IPL & NIR for Anti-Aging

IPL (Intense Pulsed Light) is a highly popular non-invasive cosmetic procedure. It utilizes a specific wavelength of polychromatic pulsed light to perform aesthetic treatments on the skin through the principle of selective photothermolysis.

NIR laser technology has gained widespread application in cosmetic treatments due to its non-invasive, painless, and short recovery time characteristics. It can provide comprehensive skin quality improvements, including tightening, whitening, brightening skin tone, and improving skin laxity.



IPL is a broad-spectrum light with a wavelength range typically between 400-1200nm. It differs from laser light, which is monochromatic and coherent, while IPL is incoherent and non-collimated. The light source of IPL is released by a high-energy xenon flash lamp under tens of thousands of volts of high pressure, hence it is referred to as a polychromatic pulsed light source that includes various colors of light.

The working principle of IPL is based on selective photothermolysis. The skin contains multiple chromophores such as melanin, hemoglobin, and water, each with different levels of light absorption. The broad-spectrum light of IPL covers the main absorption peaks of these chromophores, and by using filters, wavelengths that are more readily absorbed by specific chromophores can be selected.

Melanin: Absorption of light decreases as the wavelength increases within the range of 290-1200nm.

Hemoglobin: Has three absorption peaks at 418nm, 542nm, and 577nm.

Water: The absorption spectrum is mainly in the near-infrared range.

By adjusting the parameters of the IPL device, such as pulse width, pulse interval, and energy density, treatments can be targeted at different chromophores. The pulse width should be shorter than the thermal relaxation time of the chromophore to ensure that the light energy is concentrated on the target chromophore rather than being transmitted to the surrounding tissue. Pulse interval and synchronous cooling techniques help protect the epidermis and reduce adverse reactions.

Application & Principle

1Skin AgingIPL stimulates the production of collagen and elastin in the skin through thermal effects, thereby increasing skin thickness and elasticity, and reducing the appearance of wrinkles and fine lines.The skin becomes firmer and smoother, with an even complexion and reduced wrinkles.
2Pigmented Skin Lesions The broad-spectrum light of IPL targets melanocytes, destroying overactive ones through selective photothermolysis, which reduces pigmentation.Melasma, sun spots, age spots, and other pigmented lesions are significantly improved, resulting in more uniform skin color.
3Vascular Skin Lesions IPL targets hemoglobin in blood vessels, causing it to coagulate through photothermal action, thereby closing abnormal blood vessels and reducing redness and telangiectasias.Facial redness, spider veins, and other vascular lesions are effectively treated, leaving the skin looking healthier.
4Acne and Acne Scars IPL kills the acne-causing bacteria (Propionibacterium acnes) and promotes skin cell turnover through photothermal effects, improving acne symptoms and acne scars.Acne inflammation is reduced, the skin becomes smoother, and acne scars are improved.
5Hair RemovalIPL targets melanin in hair follicles, destroying the follicle structure through selective photothermolysis, achieving long-term or permanent hair removal.Body hair is reduced, leaving the skin smoother and with long-lasting results.
6Enlarged PoresIPL promotes the contraction of sebaceous glands and the regeneration of collagen through thermal effects, thereby improving the condition of enlarged pores.Pores become more refined, and the skin’s texture is improved.
7Loose SkinIPL heats deep skin tissues, stimulating the regeneration of collagen and elastin, enhancing skin firmness.Skin firmness is improved, and loose skin is visibly enhanced.
8PhotorejuvenationIPL exposure promotes skin metabolism through broad-spectrum light, improving skin texture and color.The overall texture and color of the skin are enhanced, giving a more youthful and vibrant appearance.


Multi-wavelength Light Source

IPL provides a broad-spectrum light that covers a range of 400-1200nm wavelengths. This polychromatic feature allows IPL to target a variety of skin concerns, such as pigmentation, vascular lesions, and skin aging, with customized treatment protocols.

Selective Photothermolysis

IPL utilizes the principle of selective photothermal action, which enables precise targeting of specific skin layers and problem areas, such as melanin, hemoglobin, and water. This means that IPL can treat particular skin issues while minimizing damage to the surrounding healthy tissue.

Broad Range of Indications

IPL is suitable for a wide array of cosmetic treatments, including but not limited to, freckle removal, skin rejuvenation, hair removal, acne treatment, and improvement of capillary dilation. This broad range of applications makes IPL a versatile tool in aesthetics.

Non-Invasive Treatment

IPL is a non-invasive treatment method that does not require surgery or cutting, resulting in minimal damage to the skin. This makes IPL an excellent option for patients seeking non-invasive cosmetic treatments.

Quick Treatment Process

IPL treatments are typically quick and efficient, taking only a few minutes to half an hour per session, making it well-suited for the fast-paced modern lifestyle, with patients resuming normal activities immediately after treatment.


Compared to some more expensive laser treatments, IPL treatments generally have a lower cost, making it more appealing to cost-conscious consumers.



NIR lasers are a type of laser that emits light within the near-infrared spectrum, typically with wavelengths ranging from 700 to 2500 nanometers (nm). This spectral range lies just beyond the visible light spectrum, which spans from 400 to 700 nm, and before the mid-infrared spectrum. The development of NIR lasers began in the mid-20th century, following the invention of the first laser in 1960. Researchers recognized the potential of the near-infrared spectrum, particularly its ability to penetrate biological tissues without causing significant damage. This unique attribute led to the initial adoption of NIR lasers in medical applications.

The working principle of NIR lasers is based on the process of stimulated emission. The laser excites atoms or molecules to a higher energy state, and when these excited particles return to their ground state, they release a photon. In a laser, this process is amplified to produce a coherent and parallel beam of light. The specific material used in the laser device structure, commonly referred to as the “gain medium,” determines the wavelength of the emitted light.

Application & Principle

1Skin Tightening and Anti-AgingNIR lasers heat the water molecules in the dermis, causing collagen fibers to contract and stimulating the production of new collagen fibers, similar to the principle of radiofrequency treatment. This thermal effect can promote the metabolism of skin cells, enhancing skin firmness and elasticity.The skin appears more tightened after treatment, with fine lines and wrinkles improved, and an overall younger-looking complexion.
2Improving Skin Tone and TextureNIR lasers can enhance blood circulation in the skin and promote cell renewal, thereby improving uneven skin tone and rough texture.The skin tone becomes more even, the texture smoother, and the overall health of the skin is enhanced.
3Enlarged PoresThrough thermal effects, NIR lasers stimulate the production of collagen, filling in the gaps around the pores, thereby reducing the prominence of the pores.Pores become more refined, and the skin surface is smoother.
4Skin SaggingNIR lasers target the deeper layers of the skin with heat, promoting the reshaping of collagen and the generation of new collagen, strengthening the skin’s support structure.Conditions of skin laxity are improved, especially in areas such as the cheeks, neck, and jawline.
5Skin Whitening and BrighteningNIR lasers promote the renewal of epidermal cells, reduce pigmentation, and increase the skin’s luminosity by improving microcirculation.The skin tone becomes brighter, and dark spots and hyperpigmentation are improved.


Deep Penetration Capability

The wavelength range of NIR lasers (typically 700 to 2500 nanometers) allows for deeper penetration into the skin compared to other types of light, such as visible light. This deep penetration capability enables NIR lasers to directly target the dermis, stimulating collagen production and remodeling, effectively improving skin firmness and elasticity.

Non-Invasive and Low Side Effects

Compared to other technologies that require invasive procedures, NIR laser treatment is non-invasive, reducing the risk of damage to surrounding healthy tissue. Additionally, NIR treatments generally have low side effects, such as temporary mild redness, making it an ideal choice for patients seeking low-risk cosmetic treatments.

Fast Treatment Speed

NIR laser treatments are quick and can be completed within a lunchtime, without disrupting the patient’s daily routine. This feature makes NIR lasers an ideal choice for busy modern individuals as it provides significant cosmetic results in a short amount of time.

Improvement of Various Skin Concerns

NIR laser can improve a variety of skin concerns, including uneven skin tone, enlarged pores, skin laxity, and fine lines. This versatility makes NIR technology a comprehensive beauty solution. By stimulating the production and remodeling of collagen, NIR lasers help to increase the skin’s luminosity, texture, and transparency.
