How Do Laser Treatments Work?
Laser scar treatment precisely targets scars using beams of light to either remove scar tissue or stimulate collagen production. This creates holes in the scar tissue, allowing the body to regenerate new, smoother skin.
The body’s response to laser treatments is gradual, often taking several months, during which new, healthy skin develops, reducing the visibility of scars over time. Laser technology is precise in targeting scar tissue and directs photothermal energy towards the scar while minimizing the impact on surrounding skin.
However, not all lasers are the same, so researching the right one for you is crucial.
Scar Removal Lasers
Lasers can differ in wavelength and mechanism, thus serving different purposes for scar treatment. Some commonly used ones include:
Erbium YAG Lasers (2940 nm)
Er:YAG lasers focus on the water content in skin cells, leading to vaporization and removal of micro-layers of skin. This creates channels that stimulate new cell and collagen production. Their effectiveness in removing various skin lesions with minimal thermal damage makes them a safer choice for treating acne scars.
CO2 Lasers (10600 nm, 2940 nm)
CO2 lasers are mainly used for treating fine lines, wrinkles, and pigmentary disorders. They work by causing thermal damage below the scarred area, which aids in scar removal. These lasers are also effective in re-pigmentation and treating conditions like vitiligo and melasma by targeting the affected areas specifically.
Q-Switched Lasers
Besides Er:YAG and CO2 lasers, Q-switched lasers are used for scar removal. These lasers store energy and release it in a single burst, removing the outer skin layer at a higher energy level and generating heat in the underlying tissue. This triggers collagen production, improving skin tone and texture.
Q-switched lasers are particularly effective for atrophic facial acne scars, such as rolling scars and larger boxcar scars.
Other Lasers (Non-Ablative Nd:YAG and KTP Lasers)
Non-ablative lasers like the Nd:YAG and KTP lasers heat the underlying skin tissue without damaging the surface. This stimulates collagen production and promotes natural healing, improving scar texture and appearance. The Nd:YAG laser penetrates deeper, while the KTP laser is known for its precision and ability to target superficial vascular changes.
SHI’s Impact on Scar Healing
At the Scar Healing Institute, we employ cutting-edge laser technologies for our SHIlase laser scar treatment, utilizing both ablative and non-ablative lasers. Our preferred ablative lasers for acne scars include Er:YAG, CO2, and Q-switched Fotona Starwalker lasers. Our expert providers use these powerful lasers in both fractional and fully ablative modes to effectively eliminate unwanted scars and promote beautiful skin healing. Additionally, at SHI, we use non-ablative lasers such as Nd:YAG and KTP to remodel scars and reduce redness. Each laser has a specific wavelength and light frequency, enabling precise penetration to the exact depth needed to target scars.
How To Prepare for Laser Scar Treatment
Before embarking on your journey to smoother skin, several essential steps should be taken to prepare for laser scar treatment. The first step is to schedule a consultation with a trusted provider to discuss your specific needs and review your medical history related to scar treatment, including the scar’s age, previous treatments, and the type of trauma or surgery that caused it.
Prior to undergoing laser scar treatment, it is recommended to:
- Avoid photosensitive medications and over-the-counter pain relievers such as aspirin.
- Pre-treat with lightening cream to prevent hyperpigmentation.
- Avoid exfoliation and discontinue the use of products with harsh chemicals, such as retinoid creams, glycolic acid, and more.
- Avoid sun exposure 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, understanding the best treatment option for each type of scar is a must. This section will provide a detailed look at the different scar types and the best laser treatment options for each.
Acne Scars
While Er:YAG, CO2, and other fractional ablative lasers can visibly improve acne scars, these lasers primarily use light to blend the healthy skin around the scars to match the level of the pitted areas, creating a more even appearance. At SHI, we believe that laser treatments should not be the first line of treatment for acne scars. Instead, we view them as a final “touch” to smooth your skin after scar revision and healing in the Phase System. This way, laser treatments can effectively refine and enhance your skin’s appearance to meet your desired goals.
We often use a combination of non-ablative and ablative lasers for acne scar removal, achieving the best results alongside other skin-rejuvenating procedures like chemical peels and microdermabrasion.
Breast Lift Scars
Nd:YAG redness lasers and Er:YAG fractional resurfacing lasers have proven effective in treating hypertrophic breast lift scars, with individuals experiencing reduced scar erythema. Nd:YAG laser treatment works through selective photolysis of scar tissue to disrupt microvessels, helping to reduce red or pink discoloration, alleviate pain and itchiness, and smooth 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 scar fading and achieve smooth, evenly toned skin. It is advisable to wait approximately a year after tummy tuck surgery before considering laser scar reduction treatments, allowing for adequate healing and maturation of the scars.
Hypertrophic & Keloid Scars
Pulsed-dye lasers (PDL) and Nd:YAG lasers are highly regarded for treating raised acne scars and other hypertrophic lesions. These lasers target blood inside the veins without affecting the surrounding tissue, reducing the red or pink color of the scar, alleviating pain and itchiness, and potentially flattening the raised appearance of hypertrophic scars.
Laser Aftercare
After completing your laser scar removal procedure, understanding the post-treatment care and recovery process is crucial. Following the treatment, it’s recommended to apply prescribed ointments like Stratamed, Stratacel, or Vaseline and avoid using harsh products such as retinols and acids during the healing period. Additionally, it’s essential to avoid sun exposure for 7-14 days before and after the laser treatment to reduce the risk of skin pigmentation changes. Some healthcare providers suggest using lightening creams to prevent hyperpigmentation. At the Scar Healing Institute, we offer a specially formulated lightening cream with key ingredients to aid in the healing process.
The recovery timeline and results depend on the type of laser treatment and individual factors. Laser treatments generally have minimal downtime, with the most noticeable improvements in scar appearance typically occurring between 3 and 6 months after the last session. Full results usually become apparent within four to six months as the skin tightens and collagen remodeling continues.
Potential Risks of Laser Scar Removal
As with any procedure, laser scar removal carries potential risks and complications, including erythema, bruising, and post-inflammatory hyperpigmentation. Erythema typically intensifies within the first 24 to 48 hours and can persist for up to four months. Post-inflammatory hyperpigmentation usually appears two to four weeks after treatment and is more common in individuals with darker skin types.
Selecting the Right Provider for Laser Scar Treatment
The operator’s skill is crucial for laser scar treatment due to the significant variations in handpieces, settings, and laser types. Your provider should have qualifications such as being a licensed esthetician, cosmetologist, or dermatologist.
Experience is critical, as laser scar treatment requires professionals skilled in using the laser device and effectively addressing patient needs. Reliable reviews for providers offering laser scar treatment can be found on reputable websites like Yelp, Google Reviews, and RealSelf.
Combining Treatments for Scar Removal
Beyond laser therapy, several other treatments can complement the process for optimal results in addressing acne scarring. Subcision therapy, for instance, involves inserting a small needle beneath the skin to elevate scars that are tethered down, particularly effective for rolling and boxcar acne scars. Chemical peels also aid in scar removal by applying a chemical solution to exfoliate the outer layer of old skin, thereby improving the appearance of scars. Additionally, ultrasound imaging can facilitate the mapping of your scars and can be conducted during your consultation.
Summary
Laser scar removal is a revolutionary non-invasive procedure that utilizes light energy to enhance the appearance of scar tissue. With a range of lasers and treatment options available, laser scar removal can effectively improve various types of scars. However, understanding the preparation process, post-treatment care, risks, and complications is crucial. Choosing the right provider and complementing laser treatment with other therapies can help achieve optimal results.
