Pulse light

Types of pulse lights

Pulse light technology is a popular hair removal method. It uses high-intensity light energy to remove unwanted hair. The light gets absorbed by the hair follicles. This causes the hair to fall out and stop growing back. There are two main pulse light types. They are described below:

• IPL hair removal machine

  It is one of the most common pulse light types. It is a broad-spectrum light device. It delivers light energy to the skin. This energy targets specific chromophores or color-producing molecules. The light destroys the targeted molecules. This process helps to treat various skin concerns. These concerns include hair removal, acne treatment, and reducing wrinkles or age spots. The devices come in different models and designs. There are portable or handheld IPL machines. People use the smaller, more manageable IPL machine for home use. The larger, fixed model devices are used in professional settings like hospitals and clinics.

• Optical devices

  These devices use intense pulsed light technology for skin therapy. They treat skin problems like acne, wrinkles, and pigmentation. The optical instruments contain filters that remove specific light wavelengths. They have pulse generators that produce short, high-energy light pulses. Optical devices are used in medical and cosmetic settings. They provide non-invasive treatments for various skin conditions.

How to choose pulse lights

• Skin Type/Concern: Select a model based on skin type and concerns. For example, if someone has sensitive skin, they will need a light with a lower energy setting. Higher energy settings may be required for coarse or thick skin. The right choice will ensure a comfortable treatment and effective results.
• Flash Lamp Replacement: Some pulse lights have a replaceable flash lamp, while others have a built-in, non-replaceable flash lamp. A replaceable flash lamp unit allows users to change it if it no longer provides good results. A built-in unit requires the entire device to be replaced if the lamp wears out. Consider which option is more convenient and cost-effective.
• Energy Levels: Look for pulse lights with multiple energy levels so treatments can be adjusted according to pain tolerance and effectiveness. Higher levels are usually more painful but may provide faster results. Lower levels take longer but are more comfortable.
• Skin Contact: Models that require direct skin contact may be more effective but less convenient than those that do not require contact. Consider any advantages or disadvantages of each type.
• Body Part Attachments: Some pulse lights include attachments for specific body parts, like the bikini area, underarms, or the face. These attachments have smaller openings and are designed for those areas. Having attachments can make treatments more targeted and efficient.
• Pulse Light Technology: The different types of pulse lights vary mainly in their technology. Some utilize infrared light, while others use intense light or laser energy. Each type has its own set of advantages and disadvantages. Research the technologies to determine which best meets individual needs.

How to use, install, and product safety

Pulsed light is a versatile technology that can treat different skin conditions like acne, wrinkles, and pigmentation. Here are some steps to follow.

• How to use

  Cleanse the skin with a gentle cleanser to remove makeup and oil. Pat the skin dry with a towel. Shave the treatment area if using on hair. This prevents hair from interfering with the light pulses. Put on the safety glasses provided to protect the eyes from the bright flashes of light. Apply a thin layer of ultrasound gel to the treatment area. This gel helps conduct the light pulses to the skin.

• Apply the Device

  Press the device firmly against the skin in the treatment area. Press the pulse button to release the light pulses. Move the device in circular or sliding motions across the treatment area. Do this until reaching the desired results. After completing the process, wipe the device with a clean cloth. Remove the gel from the skin using a gentle cleanser. Pat the skin dry with a towel. Apply a thin layer of moisturizer to hydrate the skin.

• Installation

  For models requiring installation, attach the light head to the handle or base. Plug the device into a power outlet using the power cord. Turn on the device using the power button. Select the appropriate treatment settings according to the user manual.

• Product Safety

  Follow the guidelines provided in the user manual. Avoid using the device over moles, wounds, or irritated areas. Stay clear of the eyes when using the light on hair. Avoid sun exposure before and after treatment. Wear sunscreen with an SPF of at least 30.

Functions, features, and designs of pulse lights

The function, feature, and design of pulse lights are as follows:

Function

Pulse light therapy is a skin treatment that improves skin conditions. The intense light energy targets different skin concerns. It reduces fine lines, wrinkles, and age spots. It also reduces redness and rosacea and improves skin texture. This treatment is non-invasive and requires little or no downtime.

Feature

Many pulse light machines have the following features:

• Modes: IPL machines have different modes for various skin concerns. This includes options like hair removal, acne treatment, or skin rejuvenation.
• Fluence: It is the maximum energy output measured in J/cm2. Higher fluence provides better treatment and results.
• Pulse light wavelengths: The machine emits different wavelengths of light. It has 410 nm for acne treatment, 560 nm for hair removal, 590 nm for vascular and pigmented lesions, and 640 nm for deep wrinkles.
• Spot size: This is the size of the treatment area. It can be small (12 to 15 mm) or large (up to 50 mm). A larger spot size treats more areas, while a small size is more precise.
• Filters: Pulse light machines have different filters for each treatment. For example, an acne filter is provided for that treatment.
• Cooling technology: It provides patient comfort and safety during treatment. Machines use air, gel, or hand-held device cooling systems.

Design

Pulse light machines have a simple design. They have a main unit that generates light. There is a treatment head that emits the light onto the skin. Some models have a cooling unit to provide comfort during treatment.

Q&A

Q1. Is IPL harmful?

A1. Research indicates that IPL is safe. It doesn't damage internal tissues or organs and operates within safety standards. But, it's vital to use the device following guidelines to avoid side effects like skin irritation and burns.

Q2. Can IPL permanently remove hair?

A2. Yes, IPL hair removal devices can achieve permanent hair reduction. Compared to laser hair removal, which is called a "permanent" hair removal method, IPL treatments may require more frequent sessions to achieve permanent hair reduction. After using the IPL device, most people have to shave infrequently, but some may choose to undergo laser treatment for quicker results.

Q3. How often should IPL be used?

A3. During the initial stage of IPL treatment (usually the first one or two months), it should be used once or twice a week. After that, it can be used once every two weeks or longer, depending on individual hair regrowth.

Q4. What are the disadvantages of IPL?

A4. IPL can be painful and cause skin reactions like redness and swelling. It may also be less effective on darker skin tones or light hair colors. Some devices have limited treatment areas, requiring more frequent treatments, and results may vary among individuals.
