How Laser Treatments Work
Laser scar treatment operates with precision to treat scars. Beams of light are used to either remove scar tissue or stimulate the production of collagen, creating holes in the scar tissue and allowing the body to regenerate new, smoother skin.
The body’s response to laser treatments is a gradual process, often taking several months, during which new, healthy skin develops, leading to a reduction in the visibility of scars over time. Laser technology is also precise in targeting scar tissue, directing photothermal energy towards structures within the scar tissue, while minimizing impact on the surrounding skin.
However, not all lasers are identical, so it is important to research which one is right for you.
Types of Lasers for Scar Removal
Lasers can differ in wavelength and mechanism and each one can serve a different purpose for scar treatment. Some commonly used ones include:
Erbium YAG Lasers (2940 nm)
Er:YAG lasers operate by targeting the water content in skin cells, leading to their vaporization and the removal of micro-layers of skin. This process creates channels that encourage the production of new cells and collagen. Their efficacy in eliminating different skin lesions while causing minimal thermal damage to the treated skin makes them a safer option for addressing acne scars.
CO2 Lasers (10600 nm, 2940 nm)
CO2 lasers are predominantly utilized for the treatment of fine lines, wrinkles, and various pigmentary disorders. They function by causing thermal damage below the area of scarring, proving to be effective in scar removal. They have demonstrated effectiveness in facilitating re-pigmentation and addressing conditions like vitiligo and melasma by specifically targeting the affected areas.
Q-Switched Lasers
Apart from Er:YAG and CO2 lasers, other types of lasers, such as Q-switched lasers, are also used for scar removal. These lasers work by storing energy and releasing the beam all at once, eliminating the outer skin layer at a much higher energy and generating heat in the underlying tissue. This triggers collagen production, resulting in enhanced skin tone and texture.
Q-switched lasers are especially effective in addressing atrophic facial acne scars, including atrophic scars, rolling scars, and larger boxcar scars.
Other Lasers (Non-Ablative Nd:YAG and KTP Lasers)
Unlike ablative lasers that remove the top layer of the skin, non-ablative lasers, such as the Nd:YAG laser and KTP laser, work by heating the underlying skin tissue without harming the surface. This process stimulates collagen production and promotes the natural healing process, improving the texture and appearance of scars. The Nd:YAG laser is particularly beneficial due to its deeper penetration while the KTP laser is known for its precision and ability to target superficial vascular changes.
Our Impact on Scar Treatments
At the Scar Healing Institute, we use the most advanced laser technologies for our SHIlase laser scar treatment. These include both ablative and non-ablative lasers. Our favorite ablative lasers for acne scars include Er:YAG, CO2, and the Q-switched Fotona Starwalker lasers. Our expert acne scar treatment providers use these powerful lasers in both fractional and fully ablative modes to destroy unwanted scars and allow the skin to heal beautifully. At SHI, we also utilize non-ablative lasers including Nd:YAG and KTP to remodel scars and reduce redness. All of our lasers have a specific wavelength and frequency of light which allows them to penetrate to the exact depth into the skin to target the scars wherever they reside.
Preparing for Laser Scar Treatment
Before initiating your quest towards smoother skin, several key steps should be taken in preparation for laser scar treatment. The first step involves arranging a meeting with a trusted provider to address your individual requirements and examine your medical history associated with treating scars, such as its age, prior treatments, and the type of trauma or surgery that led to it.
Prior to undergoing laser scar treatment, it is advisable to:
- Abstain from photosensitive medications and over-the-counter pain relievers such as aspirin.
- Pre-treat with a hydroquinone to prevent hyperpigmentation.
- Refrain from exfoliating and temporarily discontinue the use of retinoid creams, glycolic acid, salicylic acid, or lactic acid treatments.
- Avoid sun exposure before and after laser scar removal treatment due to its potential to induce pigment changes in the skin.
- Refrain from smoking since it can hinder the skin’s healing ability and disrupt blood flow.
Laser Treatment Options for Different Scar Types
Given the variety of scars and laser treatments, comprehending the best laser treatment options for each scar type is necessary. This section will provide a detailed look at the different scar types and the best laser treatment options for each.
Acne Scars
Although visible improvement can be seen with Er:YAG, CO2 and other fractional ablative laser treatment, lasers essentially use light to blend healthy skin around acne scars to match the level of the pitted scars. This allows a more even appearance. As a result, our firm belief at SHI is to avoid laser treatments as a first line treatment for acne scars. Instead, we believe that laser treatments are best used as a final “touch” treatment that smooths out your skin after your scar revision and healing during the Phase System. This way, laser treatments can be used as an effective refining and enhancing treatment to fine tune your skin’s appearance to your desired goals.
We often use non-ablative lasers and ablative lasers for acne scar removal. The best results can be achieved through a combination of skin-rejuvenating procedures, including lasers, chemical peels, and microdermabrasion.
Breast Lift Scars
Nd:YAG redness lasers and Er:YAG fractional resurfacing lasers have demonstrated effectiveness in addressing hypertrophic breast lift scars, with individuals experiencing reductions in scar erythema. Nd:YAG laser treatment operates through the selective photolysis of scar tissue to disrupt microvessels, thereby contributing to the reduction of red or pink discoloration, alleviation of pain and itchiness, and smoothing of the appearance of hypertrophic scars.
Tummy Tuck Scars
Er:YAG laser therapy is commonly recommended for tummy tuck scars due to its ability to expedite the fading of scars, with the goal of achieving a smooth and evenly toned skin appearance. It is advisable to wait for approximately a year following tummy tuck surgery before considering laser scar reduction treatments, in order to allow for adequate healing and maturation of the scars.
Hypertrophic & Keloid Scars
Pulsed-dye lasers (PDL) and Nd:YAG lasers are widely respected for their effectiveness in treating raised acne scars and other hypertrophic lesions. This is due to their ability to target blood inside the vein without impacting the surrounding tissue. These treatments can reduce the red or pink color of the scar, alleviating associated pain and itchiness, and potentially flattening the raised appearance of hypertrophic scars.
Post-Laser Scar Treatment Care and Recovery
Upon completion of your laser scar removal procedure, grasping the post-treatment care and recovery process is imperative. Following the treatment, it is recommended to use a prescribed ointment such as Stratamed, Stratacel, and Vaseline and discontinue any harsh products such as retinols and acids during the healing process. It is also crucial to avoid sun exposure for 7-14 days prior to and post laser scar treatment to mitigate the risk of pigment alterations to the skin. Some healthcare providers recommend lightening creams to deter hyperpigmentation. At the Scar Healing Institute, we provide a specially compounded lightening cream with key ingredients to assist in the healing process.
The recovery timeline and results vary based on the type of laser treatment and individual factors. Laser treatments generally entail minimal downtime, and the most notable enhancements in scar appearance are typically evident between 3 and 6 months following the last laser session. The full results of laser scar removal usually become apparent within four to six months as the skin undergoes tightening and collagen remodeling progresses.
Risks & Complications of Laser Scar Removal
As with any procedure, laser scar removal carries potential risks and complications such as erythema, bruising, and post-inflammatory hyperpigmentation. Erythema generally intensifies within the initial 24 to 48 hours and may persist for up to 4 months. Post-inflammatory hyperpigmentation, usually appears 2 to 4 weeks after treatment and is more common in individuals with darker skin types.
Choosing the Right Provider for Laser Scar Treatment
The operator skill is very important for laser scar treatment because the handpieces, settings, and type of laser can vary significantly. Your provider should possess qualifications such as being a licensed esthetician, cosmetologist, or dermatologist.
The provider’s experience plays a critical role in laser scar treatment, as it necessitates professionals who are skilled in utilizing the laser device and effectively addressing patient needs. Reliable reviews for providers offering laser scar treatment can be found on reputable websites such as Yelp, Google Reviews, and RealSelf.
Combinatorial Treatments for Scar Removal
In addition to laser therapy, there are other treatments that can complement the process for optimal results in addressing acne scarring. Subcision therapy is a method for scar improvement that entails the insertion of a small needle beneath the skin to elevate scars that are anchored down, especially effective for addressing rolling and boxcar acne scars. Chemical peels also contribute to scar removal by utilizing a chemical solution to exfoliate the outer layer of old skin, leading to an improvement in the appearance of scars. Ultrasound imaging also facilitates mapping of your scars and can be performed at your consultation.
Summary
Laser scar removal is a groundbreaking non-invasive procedure that uses light energy to enhance the appearance of scar tissue. With a variety of lasers and treatment options available, laser scar removal can effectively improve various types of scars. However, it is crucial to understand the preparation process, post-treatment care, risks, and complications involved.
