Let's explore the distinctions between IPL and lasers:

Light Source:

  • IPL: IPL uses a broad spectrum of light with multiple wavelengths, typically ranging from 500 to 1200 nm. It utilises a xenon flash lamp that emits pulses of light encompassing various wavelengths within the specified range.
  • Laser: A laser emits a single, specific wavelength of light. The light in a laser is generated by a process of stimulated emission, where photons are emitted as a coherent, focused beam.


  • IPL: As mentioned earlier, IPL devices have a broad range of wavelengths. Different filters can be used to selectively filter and target specific chromophores in the skin, such as melanin or haemoglobin.
  • Laser: Each laser has a specific wavelength that determines its target chromophore. For example, lasers used for hair removal typically target melanin, while lasers used for vascular treatments may target haemoglobin.

    Energy Delivery:

  • IPL: IPL devices deliver a series of broad-spectrum light pulses that contain multiple wavelengths. These pulses are typically delivered in a continuous, non-coherent manner.
  • Laser: Laser devices deliver a single wavelength of light in a focused, coherent beam. The energy is typically delivered in short pulses, allowing for precise targeting of the desired chromophore.

    Target Chromophores:

  • IPL: Due to its broad range of wavelengths, IPL can target multiple chromophores in the skin, including melanin (pigment), haemoglobin (blood vessels), and water.
  • Laser: Different lasers are designed to target specific chromophores. For example, lasers used for hair removal primarily target melanin in the hair follicles, while lasers used for vascular treatments target blood vessels.

    Treatment Applications:

  • IPL: IPL devices are versatile and can be used for various treatments, including hair removal, skin rejuvenation, vascular lesions, pigmented lesions, and acne treatments.
  • Laser: Lasers are designed for specific applications. Different types of lasers are used for hair removal, tattoo removal, skin resurfacing, vascular treatments, and other specific aesthetic procedures.


  • IPL: IPL has a larger treatment area coverage due to the broader light spectrum and larger spot sizes used during treatment. This makes it suitable for treating larger areas of the body.
  • Laser: Lasers provide a more precise and targeted treatment due to their single wavelength and focused beam. This allows for greater control and accuracy when targeting specific areas or structures in the skin.

It's important to note that the choice between IPL and lasers depends on various factors, including the specific skin concern being addressed, the desired treatment outcome, and individual patient characteristics. A qualified professional can assess your needs and recommend the most suitable treatment modality for you.

Diode, Nd:YAG, and Alexandrite lasers are three commonly used types of lasers for hair removal. While all three lasers are effective in reducing unwanted hair, there are some key differences in terms of their wavelengths, target chromophores, skin suitability, and treatment outcomes. 

Let's explore the characteristics and distinctions of each laser:

Diode Laser:

  • Wavelength: Diode lasers typically emit light in the range of 800 to 810 nm.
  • Target Chromophore: Melanin, the pigment in hair follicles, absorbs the laser energy.
  • Skin Suitability: Diode lasers are suitable for a wide range of skin types, including light to medium skin tones.
  • Treatment Speed: Diode lasers are known for their rapid treatment speed, making them efficient for large areas like the back or legs.
  • Hair Removal Efficacy: Diode lasers provide effective hair removal results, especially for coarse and dark hair.

    Nd:YAG Laser:

  • Wavelength: Nd:YAG lasers emit light at a longer wavelength of 1064 nm.
  • Target Chromophore: Nd:YAG lasers target the haemoglobin in blood vessels surrounding the hair follicles rather than directly targeting melanin.
  • Skin Suitability: Nd:YAG lasers are suitable for all skin types, including darker skin tones, as they have a lower risk of adverse effects on the skin's pigmentation.
  • Treatment Depth: Nd:YAG lasers penetrate deeper into the skin, allowing them to reach deeper hair follicles.
  • Hair Removal Efficacy: Nd:YAG lasers can effectively treat a wide range of hair colours, including finer and lighter hair, making them suitable for patients with a broader range of hair types.

    Alexandrite Laser:

  • Wavelength: Alexandrite lasers emit light at a wavelength of 755 nm.
  • Target Chromophore: Alexandrite lasers primarily target melanin in the hair follicles.
  • Skin Suitability: Alexandrite lasers are most effective on lighter skin tones, as they have a higher risk of adverse effects on darker skin types.
  • Treatment Speed: Alexandrite lasers are known for their larger spot sizes and fast repetition rates, making them suitable for treating larger areas of the body.
  • Hair Removal Efficacy: Alexandrite lasers are highly effective in treating individuals with lighter skin and darker hair. They may not be as effective for finer or lighter hair types.

It's important to note that the choice of laser for hair removal depends on various factors, including the patient's skin type, hair colour, and individual treatment goals. A qualified professional will assess these factors to determine the most suitable laser type and treatment parameters for each patient.

IPL (Intense Pulsed Light) is a versatile and widely used technology in medical aesthetics for various skin rejuvenation treatments, including acne and hyperpigmentation treatments. From a medical perspective, IPL utilises broad-spectrum light energy to target specific chromophores in the skin, leading to a range of therapeutic effects. 

Let's explore how IPL works and its applications in skin rejuvenation, acne treatment, and hyperpigmentation treatment:

  • IPL for Skin Rejuvenation: IPL stimulates the production of collagen and promotes overall skin rejuvenation through a process called photorejuvenation. The broad spectrum of light emitted by IPL devices targets melanin (pigment) and haemoglobin (blood vessels) in the skin. This process can help address several common skin concerns:
  • Fine Lines and Wrinkles: IPL promotes collagen synthesis and remodelling, reducing the appearance of fine lines and wrinkles and improving skin texture and elasticity.
  • Sun Damage and Age Spots: IPL targets the melanin in areas affected by sun damage, age spots, and freckles, resulting in a more even skin tone and reduced pigmentation.
  • Vascular Lesions: IPL can target and reduce the appearance of small blood vessels, such as spider veins and broken capillaries, improving the overall complexion.
  • IPL for Acne Treatment: IPL can be an effective treatment option for mild to moderate acne and acne-prone skin. The mechanism of action involves several factors:
  • Bacterial Clearance: IPL emits specific wavelengths of light that can destroy the bacteria responsible for acne, particularly Propionibacterium acnes.
  • Reduction of Sebaceous Gland Activity: IPL can target and shrink overactive sebaceous glands, which produce excess oil and contribute to acne formation.
  • Anti-Inflammatory Effects: IPL can help reduce inflammation and redness associated with acne, calming the skin and promoting healing.
  • IPL for Hyperpigmentation Treatment: Hyperpigmentation refers to the darkening of the skin due to excessive melanin production. IPL can be an effective treatment option for various types of hyperpigmentation, including:
  • Melasma: IPL can help lighten the patches of hyperpigmentation associated with melasma, a common skin condition triggered by hormonal changes and sun exposure.
  • Sunspots and Freckles: IPL targets the melanin in sun-damaged areas, breaking down excess pigment and reducing the appearance of sunspots and freckles.
  • Post-Inflammatory Hyperpigmentation (PIH): IPL can address hyperpigmentation caused by skin trauma, such as acne or injury, by targeting the excess melanin in the affected areas.

IPL is one of the most versatile machines in the modern aesthetic clinic. With a broad range of indications that can be treated it is often the first machine a clinic purchases. 

Laser hair removal remains one of the single most popular treatments in the aesthetic beauty sector.
