Laser resurfacing

Overview Laser resurfacing

Laser skin resurfacing is a cosmetic procedure that uses concentrated beams of light (lasers) to improve the skin’s texture, tone, and appearance. It is effective in treating various skin concerns, including wrinkles, fine lines, scars, uneven pigmentation, and sun damage. Laser skin resurfacing stimulates collagen production and promotes new skin cell growth, leading to a smoother and more youthful complexion.

Types of Laser Skin Resurfacing

1. Ablative Lasers: These lasers remove the outer layers of the skin, promoting new skin growth.
   • CO2 Lasers: Effective for deep wrinkles, scars, warts, and enlarged oil glands.
   • Erbium Lasers: Target fine lines, wrinkles, and superficial skin issues with less downtime than CO2 lasers.
2. Non-Ablative Lasers: These lasers work by heating the underlying skin tissue without damaging the surface, stimulating collagen production.
   • Fraxel Laser: Treats fine lines, wrinkles, pigmentation issues, and scars.
   • Nd Yag Laser: Used for vascular lesions, pigmentation, and hair removal.
3. Fractional Lasers: These lasers create microscopic columns of treated skin surrounded by untreated skin, promoting faster healing.
   • Fractional CO2 Lasers: Combines the benefits of ablative lasers with fractional technology for deeper rejuvenation.
   • Fractional Erbium Lasers: Suitable for more superficial concerns with quicker recovery.
4. Pulsed-Dye Lasers (PDL): These lasers target blood vessels, making them effective for treating redness, rosacea, and broken capillaries.
5. Intense Pulsed Light (IPL): While not a laser, IPL uses broad-spectrum light to treat pigmentation, sun damage, and vascular lesions. It is less intense and requires multiple sessions for optimal results.

Procedure Details

The procedure begins with the application of a topical anesthetic to minimize discomfort. Depending on the laser type and treatment area, the procedure can take anywhere from 30 minutes to 2 hours. The laser is passed over the skin, delivering controlled pulses of light. The specific settings and intensity are adjusted based on the patient’s skin type and concerns.

Duration

The duration of laser skin resurfacing depends on the size of the treatment area and the type of laser used. A typical session can last between 30 minutes to 2 hours. Multiple sessions may be required to achieve the desired results.

Anaesthesia

Local anesthesia is commonly used for laser skin resurfacing to numb the treatment area and minimize discomfort. For more extensive treatments, especially those involving ablative lasers, sedation or general anesthesia may be used.

In/Out Patient

Laser skin resurfacing is usually performed as an outpatient procedure, allowing patients to return home the same day. In some cases, an overnight stay might be recommended for extensive treatments or if general anesthesia is used.

Post Operative

Post-operative care involves managing swelling, redness, and discomfort. Patients may need to apply prescribed ointments, keep the treated area clean, and avoid direct sun exposure. The skin may be red and sensitive for several days to weeks, depending on the laser type used. Peeling and crusting are common as the skin heals.

Recovery

Recovery times vary based on the type of laser and the depth of the treatment:

• Ablative Lasers: Recovery can take 2 to 4 weeks. The skin may remain red for several weeks to months.
• Non-Ablative Lasers: Minimal downtime, with redness and swelling subsiding within a few days.
• Fractional Lasers: Recovery is typically faster than traditional ablative lasers, with most patients resuming normal activities within a week.

Results

Results can vary based on the type of laser and the specific skin concern treated. Patients typically see smoother, more even-toned skin, with reduced wrinkles, fine lines, scars, and pigmentation. Improvements continue as collagen production increases over the following months.

Expectations

Patients should have realistic expectations about the outcomes of laser skin resurfacing. While the procedure can significantly improve skin appearance, it may not completely eliminate all imperfections. A thorough consultation with the provider will help set realistic goals and ensure the patient understands the potential results and limitations.
