Erbium YAG Lasers (2940 nm)

Er:YAG lasers function by targeting the moisture in skin cells, which leads to their vaporization and the removal of thin skin layers. This action creates micro-channels that foster the production of new skin cells and collagen. Er:YAG lasers are effective in treating various skin lesions and cause minimal thermal damage to the surrounding area, making them an excellent choice for managing acne scars.

CO2 Lasers (10600 nm, 2940 nm)

CO2 lasers are mainly used for addressing fine lines, wrinkles, and pigmentation disorders. They work by inducing controlled thermal damage below the surface of the scar, which helps in scar removal. Additionally, these lasers are effective in promoting re-pigmentation and treating conditions such as vitiligo and melasma by targeting specific areas of concern.

Q-Switched Lasers

In addition to Er:YAG and CO2 lasers, Q-switched lasers are also utilized for scar treatment. These lasers deliver a high-energy pulse that removes the outer skin layer and generates heat in the deeper tissues. This heat stimulates the production of collagen, resulting in 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, such as Nd:YAG and KTP lasers, differ from ablative types by heating the underlying skin layers while leaving the surface intact. This stimulates collagen production and enhances the skin’s natural healing process, which can improve scar texture and appearance. The Nd:YAG laser is beneficial for its deeper penetration, whereas the KTP laser is known for its precision in targeting superficial vascular issues.

Treating Scars with SHI

At the Scar Healing Institute, we utilize advanced laser technology for our SHIlase scar treatments, including both ablative and non-ablative lasers. For acne scars, our preferred ablative lasers are Er:YAG, CO2, and the Q-switched Fotona Starwalker. These lasers are expertly used in both fractional and full ablative modes to target and eliminate scars, allowing the skin to regenerate with a smoother appearance. Additionally, we use non-ablative lasers like Nd:YAG and KTP to address scar remodeling and redness. Each laser’s specific wavelength and frequency are tailored to penetrate the skin precisely, ensuring targeted treatment of scar tissue.

Preparing for Laser Scar Therapy

Before embarking on your journey to smoother skin with laser scar treatment, it’s important to take several preparatory steps. Begin by arranging a consultation with a reputable provider to discuss your unique needs and review your medical history related to scar treatment, such as the scar’s age, prior treatments, and any relevant trauma or surgery.

Prior to treatment, it is advisable to:

• Avoid photosensitive medications and common pain relievers like aspirin.
• Use hydroquinone to help prevent hyperpigmentation.
• Pause the use of exfoliating products and retinoids, as well as glycolic, salicylic, or lactic acid treatments.
• Prevent sun exposure before and after treatment to avoid pigment changes.
• Stop smoking, as it can hinder the skin’s healing process and affect blood circulation.

Laser Treatment Options for Different Scar Types

Selecting the right laser treatment depends on the type of scar you have. This section explores various scar types and identifies the most suitable laser therapies for each.

Acne Scars

Lasers such as Er:YAG, CO2, and fractional ablative types improve acne scars by using light to integrate the surrounding healthy skin with the depressed scar areas, resulting in a more uniform surface. At SHI, we believe laser treatments should be used as a final step rather than a primary one. They are best employed to refine and enhance the skin’s appearance after other scar treatment methods have been completed. 

Combining these laser treatments with additional procedures like chemical peels and microdermabrasion often produces the most effective outcomes.

Breast Lift Scars

To treat hypertrophic scars from breast lift surgeries, Nd:YAG and Er:YAG fractional resurfacing lasers offer effective solutions. Nd:YAG lasers target the blood vessels within the scar tissue, helping to reduce redness and improve the scar’s appearance. This method also alleviates associated discomfort and smooths out hypertrophic scars.

Tummy Tuck Scars

For scars resulting from a tummy tuck, Er:YAG laser therapy is frequently recommended. It helps speed up scar fading and promotes an even skin tone. Waiting about a year post-surgery before initiating laser treatments is advisable to allow sufficient time for the scars to heal and mature.

Hypertrophic & Keloid Scars

Pulsed-dye lasers (PDL) and Nd:YAG lasers are effective for managing raised and hypertrophic scars. These lasers target the blood vessels within the scar tissue, reducing the redness and discomfort while flattening the raised areas. This approach can significantly improve the appearance of hypertrophic and keloid scars.

Care Guidelines & Recovery Phase Post-Laser Scar Treatment

Once your laser scar removal procedure is finished, understanding the subsequent care and recovery process is essential. Following the treatment, it’s recommended to apply prescribed ointments like Stratamed, Stratacel, or Vaseline, while refraining from using harsh products such as retinols and acids during the healing phase. Avoiding sun exposure for 7-14 days before and after the procedure is crucial to prevent pigmentation changes. Lightening creams may also be advised to minimize hyperpigmentation, and at the Scar Healing Institute, we offer a custom lightening cream to enhance your healing process.

Recovery time and outcomes can differ depending on the type of laser treatment and individual factors. Most laser procedures involve minimal downtime, with significant improvements in scar appearance often visible between 3 and 6 months after the final session. Full results typically become clear within four to six months as the skin undergoes tightening and collagen regeneration.

Possible Risks and Issues with Laser Scar Treatment

Every laser scar treatment procedure carries certain risks and complications, such as skin redness, bruising, and post-inflammatory pigmentation changes. Redness, also known as erythema, often becomes more pronounced within the first 24 to 48 hours and can persist for up to four months. Post-inflammatory hyperpigmentation, which is more common in those with darker skin tones, typically appears 2 to 4 weeks following the treatment.

Choosing the Ideal Provider for Laser Scar Therapy

The expertise of the practitioner is crucial when selecting someone for laser scar therapy, as different lasers and their settings can vary widely. It is essential to ensure your provider has credentials such as a licensed esthetician, cosmetologist, or dermatologist. Experience is key for effective treatment, so it’s important to choose someone proficient with the laser technology and treatment methods. Reliable reviews can be found on websites like Yelp, Google Reviews, and RealSelf.

Comprehensive Scar Treatment Strategies

To maximize the effectiveness of scar removal, combining laser therapy with other treatment options can be highly beneficial. Subcision therapy, which involves a small needle to lift scar tissue, is especially useful for rolling and boxcar scars. Chemical peels help by exfoliating the skin’s surface with a chemical solution, leading to improved scar appearance. Ultrasound imaging is another valuable tool for assessing scar depth and planning treatment strategies.

Summary

Laser scar removal is an innovative, non-invasive method designed to improve scar appearance using light energy. This technique offers multiple laser options tailored to various scar types and skin conditions. To ensure the best possible outcome, it is vital to understand the necessary preparatory steps, follow-up care, and potential risks associated with the procedure. Choosing a competent provider and incorporating additional treatments can enhance effectiveness. A holistic approach to skin health, rather than focusing solely on scar removal, is essential for achieving the best results.
