Understanding Laser Treatments
Lasers operate with extreme precision, using beams of light to create holes in the scar tissue to leave room for new collagen to grow and form healthy skin.
The body gradually responds to the laser treatment over several months, during which new, healthy skin develops and the appearance of scars is minimized. Lasers are able to minimize impact on the surrounding skin, operating with extreme accuracy to direct their photothermal energy towards structures within the scar tissue.
Notedly, there are many different kinds of lasers, so it is vital to do your research.
Categories of Lasers for Scar Treatment
Scar removal involves a range of lasers, each varying in wavelength and technique, tailored for specific types of scars. Some of the most commonly applied lasers are:
Erbium YAG Lasers (2940 nm)
By focusing on the water molecules within skin cells, Er:YAG lasers effectively vaporize and remove thin layers of skin. This process creates pathways that encourage the generation of new cells and collagen. Their ability to address different skin lesions while minimizing thermal damage positions them as a safe and effective option for acne scar treatment.
CO2 Lasers (10600 nm, 2940 nm)
CO2 lasers are primarily used for addressing fine lines, wrinkles, and various pigmentary issues. They operate by creating thermal damage beneath the scarred area, making them highly effective for scar removal. These lasers have proven successful in facilitating re-pigmentation and treating conditions such as vitiligo and melasma by precisely targeting the problematic areas.
Q-Switched Lasers
Besides Er:YAG and CO2 lasers, Q-switched lasers are another option for scar removal. They function by accumulating energy and then releasing it in a concentrated burst, removing the outer skin layer and heating the underlying tissue. This stimulates collagen production, leading to improved skin tone and texture. Q-switched lasers are particularly effective for treating atrophic facial acne scars, including rolling and boxcar scars.
Other Lasers (Non-Ablative Nd:YAG and KTP Lasers)
Non-ablative lasers like Nd:YAG and KTP heat the underlying skin tissue without harming the surface layer, unlike ablative lasers. This approach stimulates collagen production and aids in the natural healing process, thereby enhancing the texture and appearance of scars. The Nd:YAG laser is especially beneficial due to its deeper tissue penetration, while the KTP laser excels in targeting superficial vascular changes with precision.
SHI’s Specialty
The Scar Healing Institute employs state-of-the-art laser technologies for SHIlase laser scar treatment, encompassing both ablative and non-ablative lasers. Our top choices for ablative lasers targeting acne scars include Er:YAG, CO2, and the Q-switched Fotona Starwalker lasers. Our experienced professionals use these lasers in both fractional and fully ablative modes to effectively eradicate unwanted scars and facilitate the skin’s natural healing. Additionally, at SHI, we utilize non-ablative lasers like Nd:YAG and KTP to remodel scars and mitigate redness. Each laser’s distinct wavelength and frequency ensure precise targeting of scars at the necessary depth.
Preparing for Laser Scar Treatment
Proper preparation is key to successful laser scar treatment. Start by consulting with a trusted provider to discuss your individual needs and review your medical history related to scar treatment, such as the scar’s age, prior treatments, and the nature of the trauma or surgery that caused it.
Before undergoing laser scar treatment, you should:
- Avoid photosensitive medications and over-the-counter pain relievers like aspirin.
- Use a hydroquinone pre-treatment to prevent hyperpigmentation.
- Refrain from exfoliating and temporarily discontinue using retinoid creams, glycolic acid, salicylic acid, or lactic acid treatments.
- Avoid sun exposure before and after the treatment to prevent pigment changes in the skin.
- Refrain from smoking, as it can impede the skin’s healing process and blood flow.
What Is the Best Laser for My Scars?
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
Er:YAG, CO2, and other fractional ablative laser treatments can visibly improve acne scars by using light to blend healthy skin around the scars to the level of the pitted areas, resulting in a more uniform appearance. At SHI, we do not recommend laser treatments as the primary approach for acne scars. Instead, we suggest using lasers as a final “touch” treatment to smooth the skin after scar revision and healing during the Phase System. This method allows laser treatments to effectively refine and enhance your skin’s appearance to meet your desired goals.
We frequently use both non-ablative and ablative lasers for acne scar removal, achieving the best results 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 shown success in treating hypertrophic breast lift scars, with reductions in scar erythema. Nd:YAG laser treatment works by selectively photolyzing scar tissue to disrupt microvessels, which helps reduce red or pink discoloration, alleviate pain and itchiness, and smooth the appearance of hypertrophic scars.
Tummy Tuck Scars
Er:YAG laser therapy is often recommended for tummy tuck scars due to its ability to speed up the fading of scars, aiming for smooth and evenly toned skin. It is advisable to wait about a year after tummy tuck surgery before considering laser scar reduction treatments to allow for sufficient 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 inside the vein without impacting 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.
Taking Care of Yourself Post-Laser
Following your laser scar removal procedure, it’s crucial to understand the post-treatment care and recovery steps. Use prescribed ointments like Stratamed, Stratacel, or Vaseline, and avoid harsh products like retinols and acids during recovery. Avoid sun exposure for 7-14 days before and after treatment to reduce the risk of pigment changes. Some providers recommend lightening creams to prevent hyperpigmentation, and at the Scar Healing Institute, we offer a specialized lightening cream to aid healing.
Recovery and results vary based on the laser type and individual factors. Laser treatments typically have minimal downtime, with noticeable improvements in scar appearance between 3 and 6 months after the last session. Full results generally emerge within four to six months as skin tightening and collagen remodeling occur.
Potential Complications of Laser Scar Removal
Laser scar removal, like any procedure, carries potential risks and complications, including erythema, bruising, and post-inflammatory hyperpigmentation. Erythema typically peaks within 24 to 48 hours and can persist for up to 4 months. Post-inflammatory hyperpigmentation usually develops 2 to 4 weeks post-treatment and is more common in individuals with darker skin tones.
How Do I Choose the Right Provider?
The expertise of the provider is crucial in laser scar treatment due to the significant variations in handpieces, settings, and laser types. It is essential to choose a provider who is a licensed esthetician, cosmetologist, or dermatologist.
Experience plays a vital role, as skilled professionals can effectively utilize laser devices and address patient needs. You can find reliable reviews on sites like Yelp, Google Reviews, and RealSelf to help identify reputable providers.
Complementary Scar Removal Treatments
For optimal results in treating acne scars, combining laser therapy with other treatments can be highly effective. Subcision therapy, which involves inserting a small needle under the skin to elevate anchored scars, is particularly beneficial for rolling and boxcar acne scars. Chemical peels contribute by using a chemical solution to exfoliate the outer skin layer, enhancing the scar’s appearance. Additionally, ultrasound imaging can be utilized during consultations to map your scars accurately, ensuring a thorough treatment plan.
Summary
Laser scar removal is an innovative, non-invasive procedure that utilizes light energy to enhance the look of scar tissue. With multiple lasers and treatment options, it can effectively treat different types of scars. However, understanding the preparation, post-treatment care, and potential risks and complications is crucial. Choosing a skilled provider and combining laser treatment with other therapies can yield the best results. Keep in mind, perfect skin requires a holistic approach to skin health.
