The Mechanism Behind Laser Treatments
Laser treatments for scars work with precision to address scar tissue by using beams of light to either remove it or encourage collagen production. This process creates small holes in the scar tissue, promoting the growth of new, smoother skin.
The body’s response to laser treatments takes time, usually several months, as new, healthy skin forms and scars become less noticeable. The technology precisely targets scar tissue, focusing photothermal energy on it while sparing the surrounding skin.
It is important to research different laser types to find the most suitable one for your needs.
What Are the Different Types of Lasers for Scar Removal?
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 target the water in skin cells, causing vaporization and removing micro-layers of skin. This process creates channels that boost new cell and collagen production. They are effective in removing various skin lesions with minimal thermal damage, making them a safer option for treating acne scars.
CO2 Lasers (10600 nm, 2940 nm)
CO2 lasers are primarily used for fine lines, wrinkles, and pigmentary disorders. They cause thermal damage beneath the scarred area, which helps in scar removal. These lasers are also effective in re-pigmentation and treating conditions like vitiligo and melasma by precisely targeting the affected areas.
Q-Switched Lasers
In addition to Er:YAG and CO2 lasers, Q-switched lasers offer an alternative approach for scar removal. These lasers work by storing and then releasing energy in a single, powerful pulse, which removes the outer skin layer with high intensity and generates heat in the deeper tissues. This process stimulates collagen production, improving skin texture and tone. Q-switched lasers are particularly effective for treating atrophic facial acne scars, including rolling scars and larger boxcar scars.
Other Lasers (Non-Ablative Nd:YAG and KTP Lasers)
Non-ablative lasers, such as 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 is known for its deeper penetration, while the KTP laser is valued for its precision and ability to target superficial vascular changes.
Scar Treatment at SHI
At the Scar Healing Institute, we utilize state-of-the-art laser technologies in our SHIlase laser scar treatment, featuring both ablative and non-ablative lasers. Our top choices for ablative acne scar treatments are Er:YAG, CO2, and Q-switched Fotona Starwalker lasers. Our skilled providers use these lasers in fractional and fully ablative modes to destroy unwanted scars and facilitate beautiful skin healing. At SHI, we also employ non-ablative lasers like Nd:YAG and KTP to remodel scars and decrease redness. Each laser’s specific wavelength and light frequency allow them to penetrate precisely to the depth required to effectively target scars.
Pre-Treatment Instructions for Laser Scar Removal
Before starting your journey towards smoother skin, it is important to take several preparatory steps for laser scar treatment. First, arrange a consultation with a trusted provider to discuss your individual needs and review your medical history related to scar treatment, including the age of the scar, previous treatments, and the type of trauma or surgery that caused it.
Prior to laser scar treatment, it is advisable to:
- 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 to prevent pigment changes in the skin.
- Avoid photosensitive medications and over-the-counter pain relievers like aspirin.
- Pre-treat with hydroquinone to prevent hyperpigmentation.
- Avoid smoking, as it can hinder the skin’s healing process and disrupt blood flow.
Laser Treatment Options for Different Scar Types
Understanding the different options available for laser resurfacing is important when making a treatment decision. 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 laser treatments can improve acne scars, these lasers work by using light to blend the healthy skin around the scars to match the pitted areas, resulting in a more even appearance. At SHI, we believe laser treatments should not be the first treatment option for acne scars. Instead, they should be used as a final “touch” after scar revision and healing during the Phase System, effectively refining and enhancing your skin’s appearance to meet your goals.
We use a combination of non-ablative and ablative lasers for acne scar removal, achieving the best results with additional skin-rejuvenating procedures like chemical peels and microdermabrasion.
Breast Lift Scars
Nd:YAG redness lasers and Er:YAG fractional resurfacing lasers have shown effectiveness in treating hypertrophic breast lift scars, with individuals seeing reductions in scar erythema. Nd:YAG laser treatment works by selectively photolyzing scar tissue to disrupt microvessels, reducing red or pink discoloration, alleviating pain and itchiness, and smoothing the appearance of hypertrophic scars.
Tummy Tuck Scars
Er:YAG laser therapy is often recommended for tummy tuck scars due to its ability to accelerate scar fading and achieve smooth, evenly toned skin. It is advisable to wait about a year after tummy tuck surgery before considering laser scar reduction treatments to allow for proper healing and scar maturation.
Hypertrophic & Keloid Scars
Pulsed-dye lasers (PDL) and Nd:YAG lasers are known for their effectiveness in treating raised acne scars and other hypertrophic lesions. These lasers target blood within the veins without affecting surrounding tissue, reducing the red or pink color of the scar, alleviating pain and itchiness, and potentially flattening the raised appearance of hypertrophic scars.
Aftercare for Laser Scar Treatment
Upon finishing your laser scar removal procedure, it’s essential to understand the post-treatment care and recovery process. After the treatment, it’s advised to use prescribed ointments like Stratamed, Stratacel, or Vaseline and avoid harsh products such as retinols and acids during the healing phase. It’s also important to stay out of the sun for 7-14 days before and after the laser treatment to minimize the risk of pigmentation changes. Some healthcare professionals recommend using lightening creams to prevent hyperpigmentation. At the Scar Healing Institute, we provide a specially compounded lightening cream with key ingredients to support the healing process.
The recovery timeline and results vary based on the type of laser treatment and individual factors. Laser treatments typically involve minimal downtime, with the most significant improvements in scar appearance seen between 3 and 6 months after the final session. Full results usually become visible within four to six months as the skin tightens and collagen remodeling takes place.
Laser Scar Removal: Risks & Possible Complications
Like any medical procedure, laser scar removal has potential risks and complications, including erythema, bruising, and post-inflammatory hyperpigmentation. Erythema typically peaks within the first 24 to 48 hours and can last up to four months. Post-inflammatory hyperpigmentation generally appears two to four weeks after treatment and is more prevalent in individuals with darker skin tones.
How to Pick the Right Provider for Laser Scar Treatment
The skill of the operator is essential for successful laser scar treatment due to the variations in handpieces, settings, and laser types. It is important that your provider is a licensed esthetician, cosmetologist, or dermatologist.
Experience is crucial, as effective laser scar treatment requires professionals adept at using the laser device and meeting patient needs. Reliable reviews for providers can be found on reputable websites such as Yelp, Google Reviews, and RealSelf.
Enhancing Scar Removal with Additional Treatments
In addition to laser therapy, other treatments can complement the process for optimal results in treating acne scars. Subcision therapy is a technique where a small needle is inserted beneath the skin to lift scars that are bound down, making it especially effective for rolling and boxcar acne scars. Chemical peels contribute to scar removal by applying a chemical solution to exfoliate the outer layer of old skin, thereby enhancing the appearance of scars. Furthermore, ultrasound imaging can help map your scars and can be performed during your consultation.
Summary
Laser scar removal is an innovative non-invasive procedure that uses light energy to improve the appearance of scar tissue. With a variety of lasers and treatment options available, laser scar removal can effectively treat various types of scars. It is essential to understand the preparation process, post-treatment care, risks, and complications involved. Choosing the right provider and supplementing laser treatment with other therapies can help achieve the best results.
