Laser

Modern laser procedures provide advanced options for addressing various skin concerns, including acne scarring, pigmentation, and skin laxity. Clinics in Sydney provide access to sophisticated laser technologies such as CO2 laser skin resurfacing and non-ablative fractional lasers to address skin quality and texture. This guide provides information regarding fractional CO2 laser treatments and non-ablative resurfacing methodologies.

CO2 Laser Treatment and Its Mechanism
The high-energy carbon dioxide laser used in CO2 laser treatment performs precision-based removal of specific skin layers to address skin quality. This technology produces brief pulses of light which evaporate the superficial layers and may support collagen synthesis in the deeper dermis. Skin regeneration occurs through this process, resulting in a refreshed appearance and firmer skin texture.
The procedure is generally categorised into two modalities: ablative and fractional. Ablative procedures remove entire skin layers to treat more significant lines and scarring. A fractional CO2 laser system treats microscopic columns of skin, leaving adjacent tissue intact, which typically influences the recovery timeframe.

How Does CO2 Laser Skin Resurfacing Work?
Laser energy pulses from CO2 skin resurfacing systems are used to address specific skin cells and support collagen production. The laser beam passes through the surface tissues until it reaches the water-containing cells in the epidermis and dermis, vaporising the top layer while heating the second layer. The subsequent support of collagen fibres assists in developing a firmer skin appearance and smoother texture.
Experienced practitioners, including doctors and clinical therapists, deliver precise treatments to selected areas without impacting neighbouring skin, effectively addressing lines, scars, and skin pigmentation concerns.

Preparing for CO2 Laser Treatment
Practitioners provide necessary instructions to patients planning to undergo CO2 laser resurfacing to support the healing process and manage potential risks. Preparation typically includes:
Avoiding Sun Exposure: It is advised to avoid direct sun exposure and tanning for at least four weeks prior to the procedure.
Medication Review: The discontinuation of certain light-sensitising medications, such as doxycycline, is typically required three days before treatment.
Antiviral Medication: Patients with a history of cold sores (herpes simplex) may be advised to commence antiviral medication as a preventative measure.
Smoking Cessation: Patients are advised to avoid smoking and nicotine products before and after their treatment, as nicotine can affect healing times and treatment outcomes.

What to Expect During the Procedure
On the day of your CO2 laser treatment, the following can be expected:
Duration: The treatment process typically spans 30 minutes to 2 hours, depending on the size of the treatment area and the concerns being addressed.
Comfort Management: The treatment may involve some discomfort. Your practitioner will provide local anaesthesia or topical numbing to manage this. In cases of extensive resurfacing, further sedation options may be discussed.
Protective Measures: The skin is cleansed thoroughly, and protective eyewear is used to shield the eyes during the laser operation.

Post-Treatment Care
Following a CO2 laser treatment, diligent aftercare is important for the healing process.
Follow Clinical Advice: Personalised aftercare instructions will be provided. It is important to follow these guidelines and take any prescribed medications as directed.
Ongoing Home Care:
Cleanse Gently: Use a mild, fragrance-free cleanser and lukewarm water. Gently pat the skin dry.
Hydrate the Skin: Apply recommended recovery balms or simple emollients such as QV Intensive or Vaseline as directed to support the skin barrier.
Infection Control: As the skin barrier is temporarily affected, maintaining hygiene is important. This includes washing hands before touching the area and using clean pillowcases.
Avoid Picking: It is important not to scratch or pick at the skin during the peeling phase to avoid the risk of scarring. If itchiness occurs, an over-the-counter antihistamine may be discussed with a pharmacist.
Monitor Recovery: Report any unusual redness, persistent swelling, excessive pain, or discharge to the clinic immediately.

Types of CO2 Laser Resurfacing Procedures
CO2 laser resurfacing is classified by the depth of penetration and the associated recovery process.
Ablative CO2 Laser Resurfacing: Healthcare providers remove the epidermis to heat the underlying dermis, stimulating collagen production. This method is used for more significant lines and sun damage. Recovery time typically extends to approximately fourteen days.
Non-Ablative CO2 Laser Resurfacing: These systems generate heat in the deeper skin layers while keeping the surface layer intact. This technique stimulates collagen formation with a different recovery profile. It is often suitable for addressing early skin changes and typically requires multiple sessions for optimal results.

Considerations for CO2 Laser Treatment
Management of Lines and Textural Changes: CO2 laser treatment is used to address the appearance of fine lines and skin texture.
Enhancement of Skin Characteristics: Skin texture may change following therapy due to collagen remodelling.
Scar Management: The procedure can be used to address rough skin surfaces and the appearance of certain types of scarring.
Address Pigmentation: Used in the management of hyperpigmentation and sun-related skin changes.
Skin Support: Patients may observe a change in skin firmness as the treatment involves structural collagen remodelling.

Common Laser Applications
CO2 Laser Skin Resurfacing: Often used for addressing sun damage and surface irregularities. Specific protocols exist for sensitive areas such as the skin surrounding the eyes and mouth.
Fractionated Laser Treatment: These procedures use fractionated beams for the management of scars and pigmentation. They are frequently used for acne scar management and addressing skin texture.
Laser Scar Management: Clinical methods involve the breakdown of scar tissue to stimulate new collagen, suitable for addressing acne scarring or surgical scars.
Laser Pigmentation Treatment: Specific wavelengths are used to address freckles and areas of hyperpigmentation. Options may include Q-switched lasers or IPL (Intense Pulsed Light) for skin tone irregularities.
Laser Neck Treatment: These procedures focus on addressing skin laxity in the neck area by stimulating collagen to support a firmer appearance.

Assessment for Laser Treatments
Suitability is determined during a clinical consultation. Factors considered include:
Acne scars or surgical scars
Texture variations or sun-related changes
Fine lines
Hyperpigmentation
Skin laxity around the face and neck
Before and After Care
Pre-Treatment:
Sun exposure must be avoided, and SPF 50+ should be applied daily.
Active skincare, such as retinol and chemical exfoliants, should be ceased one week prior.
Post-Treatment:
The skin typically exhibits redness and peeling during the initial recovery phase. Use soothing creams, maintain moisture, and ensure strict sun protection.

Duration of Results
The duration of changes following a CO2 laser treatment varies based on skin type, lifestyle factors, and ongoing skin maintenance. Results may be observed for several months to years. Periodic maintenance sessions may be recommended based on individual assessment.

Understanding Microneedling
Pros:
Supports Collagen Synthesis: The natural healing response is stimulated, which can lead to changes in skin quality.
Recovery: Microneedling is a minimally invasive option with a typically shorter recovery timeframe compared to ablative lasers.
Versatility: The treatment can be used to address various concerns including skin texture and enlarged pores across different skin types.
Cons:
Timeframe for Results: Changes in the skin occur gradually as collagen naturally synthesises. A series of sessions is typically recommended.
Potential Side Effects: Temporary pinpoint bleeding, sensitivity, redness, and mild swelling are common and usually subside within a few days.
Suitability for Laxity: While it supports skin quality, it may not address significant skin laxity as effectively as other modalities like radiofrequency microneedling or surgical interventions.
Risk Management: Adhering to aftercare is essential to manage the risk of infection while the skin's surface is healing.
