Role of Lasers in Aesthetic Medicine
Lasers have revolutionised aesthetic medicine by offering non-invasive and precise treatments for a wide range of skin concerns. Using focused light energy, lasers can target specific skin structures without damaging surrounding tissue.
- Pigment Removal
- Skin Rejuvenation
- Vascular Lesion Removal
- Tattoo Removal
- Scar Management
Types of Lasers Available
Different types of lasers are used depending on the specific condition and skin type.
-
Q-Switched Lasers: Ideal for pigment removal and tattoo removal.
-
Pico Lasers: Advanced pigment and tattoo removal with less downtime.
-
Fractional CO₂ Lasers: Ablative lasers used for deep resurfacing, wrinkle reduction, and scar treatment.
-
Erbium Lasers: Precise resurfacing for fine lines and moderate wrinkles.
-
Pulsed Dye Lasers (PDL): Target vascular lesions like port wine stains, rosacea, and broken capillaries.
-
Nd:YAG Lasers: Versatile lasers for hair removal, vascular lesions, and deeper pigment.
How Lasers Work
Lasers emit concentrated beams of light at specific wavelengths to target various skin structures. Depending on the wavelength and type, lasers can:
- Break down melanin in pigmented lesions
- Stimulate collagen and elastin production for rejuvenation
- Vaporise scar tissue or abnormal skin layers
- Collapse blood vessels in vascular conditions
- Shatter tattoo pigments into smaller particles for natural removal
Each laser procedure is tailored to your skin type, concern, and treatment goals.
What to Expect
Laser treatments are typically performed in a clinic setting
Numbing cream maybe applied to the area 15-30 minutes prior to the procedure
Duration: The procedure may take15 minutes to over an hour, depending on the treatment area.
Post procedure the patient may experience mild redness. Pigmented areas may be come darker initially. Some treatments, like fractional resurfacing, may involve more downtime, while pigment and vascular treatments often have minimal recovery.
Recovery and Downtime
Recovery varies based on the laser type and depth of treatment:
- Mild redness and swelling may last a few hours to days
- Peeling or flaking may occur with resurfacing lasers
- Pigmented spots may darken before sloughing off
Post-Procedure Care
Post-procedure care is crucial for optimal results and includes:
- Sun protection with broad-spectrum SPF
- Gentle skincare (avoid scrubs, retinoids, and active ingredients)
- Hydration with moisturisers
- Avoiding heat exposure and strenuous activity for a few days
Risks and Complications
While laser treatments are generally safe, especially when performed by qualified professionals, potential risks include:
- Redness and swelling
- Temporary darkening or lightening of skin (post-inflammatory hyperpigmentation or hypopigmentation)
- Scarring (rare with proper technique and aftercare)
- Blistering or infection (especially with aggressive treatments)
Pre-treatment consultation and post-care compliance significantly reduce these risks.
Are laser treatments painful?
Most patients describe the sensation as a mild snapping or stinging. Topical numbing cream may be used for comfort about half an hour prior to treatment.
This depends on the severity, type of condition and type of laser used.
Yes, but not all lasers are suitable for darker skin tones. A consultation is important to choose the safest and most effective laser.
Results can appear within days to weeks depending on the treatment. Some lasers offer gradual improvement over time.
It varies. Pigment or vascular treatments often have little to no downtime, while resurfacing lasers may require a few days of recovery.
