How Laser Treatments Work
With laser scar resurfacing, beams of light are targeted to your skin in order to remove scar tissue and stimulate collagen production. By making holes in the scar tissue, lasers allow the body to regenerate new, smoother skin.
Over several months, the body responds to the laser treatment and gradually develops new, healthy skin, reducing the visibility of scars. 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 equal, so it is important to determine which one is right for you.
Different Kinds of Lasers for Scar Removal
Purpose, wavelength, and mechanism all differ between lasers. Some of the more commonly used ones include:
Erbium YAG Lasers (2940 nm)
Er:YAG lasers are designed to target the water content in skin cells, causing vaporization and the removal of micro-layers of skin. This technique opens channels that stimulate the production of new cells and collagen. Their high efficacy in eliminating various skin lesions with minimal thermal damage makes them an excellent choice for treating acne scars.
CO2 Lasers (10600 nm, 2940 nm)
CO2 lasers are highly effective for treating fine lines, wrinkles, and various pigmentary disorders. They work by inducing thermal damage beneath the scar tissue, which is crucial for effective scar removal. CO2 lasers have shown significant success in promoting re-pigmentation and treating conditions such as vitiligo and melasma by precisely targeting the affected areas.
Q-Switched Lasers
In addition to Er:YAG and CO2 lasers, Q-switched lasers are also utilized for scar removal. These lasers store energy and release it in a powerful burst, effectively removing the outer skin layer and generating heat in the underlying tissue. This process stimulates collagen production, enhancing 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 differ from ablative lasers as they heat the underlying skin tissue without damaging the surface. This method stimulates collagen production and aids the natural healing process, thereby improving scar texture and appearance. The Nd:YAG laser is notable for its deeper penetration, while the KTP laser is known for its precision in targeting superficial vascular changes.
Scar Treatments at SHI
At the Scar Healing Institute, we utilize the latest advancements in laser technology for our SHIlase laser scar treatments, incorporating both ablative and non-ablative lasers. Our preferred ablative lasers for treating acne scars include Er:YAG, CO2, and the Q-switched Fotona Starwalker lasers. Our expert team uses these powerful lasers in fractional and fully ablative modes to remove unwanted scars and promote effective skin healing. In addition, SHI employs non-ablative lasers such as Nd:YAG and KTP to remodel scars and reduce redness. Each laser’s unique wavelength and frequency allow for precise penetration to target scars accurately.
Preparing for Laser Scar Treatment
Effective preparation is vital for laser scar treatment success. Begin by arranging a consultation with a reliable provider to discuss your specific needs and review your medical history concerning scar treatment, including the scar’s age, previous treatments, and the type of trauma or surgery involved.
Before starting laser scar treatment, it is important to:
- Avoid photosensitive medications and over-the-counter pain relievers such as aspirin.
- Use hydroquinone pre-treatment to prevent hyperpigmentation.
- Avoid exfoliating and temporarily stop using retinoid creams, glycolic acid, salicylic acid, or lactic acid treatments.
- Stay away from sun exposure before and after the treatment to avoid pigment changes in the skin.
- Refrain from smoking, as it can hinder the skin’s healing process and blood flow.
Different Lasers for Different Scar Types
Considering the vast array of scar types and laser treatments, it is important to understand the first choice for each. This next section will go into detail about your options and what we have seen works best.
Acne Scars
Visible improvements are achievable with Er:YAG, CO2, and other fractional ablative laser treatments, which use light to blend healthy skin around acne scars to the level of the pitted scars, creating a more even appearance. At SHI, we do not recommend laser treatments as the first line of treatment for acne scars. Instead, we believe lasers should be used as a final “touch” treatment to smooth out your skin after scar revision and healing during the Phase System. This approach allows laser treatments to refine and enhance your skin’s appearance to achieve your desired goals.
We often employ both non-ablative and ablative lasers for acne scar removal. The best outcomes can be obtained 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 proven effective in treating hypertrophic breast lift scars, with significant reductions in scar erythema. Nd:YAG laser treatment works by selectively photolyzing scar tissue to disrupt microvessels, thereby reducing red or pink discoloration, alleviating pain and itchiness, and smoothing the appearance of hypertrophic scars.
Tummy Tuck Scars
Er:YAG laser therapy is highly recommended for tummy tuck scars due to its ability to accelerate scar fading, aiming to achieve 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 adequate healing and scar maturation.
Hypertrophic & Keloid Scars
Pulsed-dye lasers (PDL) and Nd:YAG lasers are well-regarded for their effectiveness in treating raised acne scars and other hypertrophic lesions. These lasers target blood inside the vein 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.
Post-Treatment Instructions
Upon completing your laser scar removal procedure, it’s essential to follow post-treatment care and recovery guidelines. Apply prescribed ointments such as Stratamed, Stratacel, or Vaseline, and discontinue using harsh products like retinols and acids during the recovery period. Avoiding sun exposure for 7-14 days before and after the procedure is vital to prevent pigment changes. Some providers recommend lightening creams to avoid hyperpigmentation, and at the Scar Healing Institute, we offer a specially compounded lightening cream to support the healing process.
Recovery times and outcomes vary depending on the laser treatment and individual factors. Laser treatments generally require minimal downtime, with significant scar improvement visible between 3 and 6 months after the final session. Complete results usually appear within four to six months as the skin tightens and collagen remodeling takes place.
Risks & Complications of Laser Scar Removal
As with any medical procedure, laser scar removal carries potential risks and complications, including erythema, bruising, and post-inflammatory hyperpigmentation. Erythema typically peaks within 24 to 48 hours and may last up to 4 months. Post-inflammatory hyperpigmentation often appears 2 to 4 weeks after treatment and is more common in those with darker skin tones.
Choosing the Right Provider for Laser Scar Treatment
Selecting a skilled provider is crucial for successful laser scar treatment due to the varying handpieces, settings, and types of lasers involved. Ensure your provider holds qualifications such as being a licensed esthetician, cosmetologist, or dermatologist.
Their experience is paramount, as it requires proficiency in using laser devices and effectively addressing patient needs. Reliable reviews can be found on reputable websites like Yelp, Google Reviews, and RealSelf, helping you choose a provider with a proven track record of success.
Complementary Scar Removal Treatments
Complementary treatments can enhance the results of laser therapy in addressing acne scars. Subcision therapy involves inserting a small needle beneath the skin to lift anchored scars, making it particularly effective for rolling and boxcar acne scars. Chemical peels aid in scar removal by applying a chemical solution that exfoliates the outer layer of old skin, improving the scar’s appearance. Additionally, ultrasound imaging can be used during consultations to map out your scars, providing a comprehensive approach to treatment.
Summary
Laser scar removal is a cutting-edge, non-invasive treatment that uses light energy to improve scar tissue appearance. A variety of lasers and treatment options are available to effectively address different scar types. It is important to be aware of the preparation process, post-treatment care, and potential risks and complications. Selecting an experienced provider and supplementing laser treatment with other methods can help achieve the best outcomes. Remember, flawless skin involves a comprehensive approach to skin care.
