What is Aerolase?
Aerolase is a proprietary laser system that uses 650-microsecond 1064 nm Nd:YAG technology for various dermatologic and aesthetic applications, including acne treatment, skin rejuvenation, vascular lesions, and hair removal.
Technology Overview
The Aerolase laser platform represents one of over 150 commercially available laser systems currently on the market for dermatologic indications 1. It utilizes a specific wavelength and pulse duration designed to target multiple chromophores in the skin while minimizing thermal damage to surrounding tissues 2, 3.
Key Technical Features
- Wavelength: 1064 nm Nd:YAG laser technology, which provides deeper tissue penetration compared to shorter wavelengths 4, 5
- Pulse Duration: Ultra-short 650-microsecond pulses that reduce heat diffusion and minimize discomfort
- Mechanism: The longer wavelength targets oxyhemoglobin in blood vessels, melanin in pigmented lesions, and can induce photothermolysis effects 6
Clinical Applications
Acne Treatment
The 1064 nm wavelength can destroy Cutibacterium acnes (formerly Propionibacterium acnes) through photoexcitation of bacterial porphyrins, releasing reactive oxygen species 6. The laser may also induce thermolysis of blood vessels supplying sebaceous glands, potentially reducing sebum production 6.
Skin Rejuvenation and Resurfacing
Non-ablative 1064 nm lasers induce dermal collagen remodeling through controlled thermal injury while preserving the epidermis, making them safer for patients with darker skin phototypes compared to ablative alternatives 5. This approach generates zones of coagulation in the dermis that stimulate neocollagenesis 3, 5.
Vascular and Pigmented Lesions
The 1064 nm wavelength effectively targets vascular lesions by preferentially absorbing in oxyhemoglobin, causing selective photothermolysis of blood vessels 6. It can also address pigmented lesions, though with less specificity than shorter wavelengths 1.
Safety Profile and Considerations
Advantages for Diverse Skin Types
The longer 1064 nm wavelength and ultra-short pulse duration make Aerolase particularly suitable for darker skin phototypes (Fitzpatrick IV-VI), as it reduces the risk of post-inflammatory hyperpigmentation compared to shorter wavelength lasers 2, 5.
Common Side Effects
- Transient erythema and edema (typically resolving within hours to days) 7
- Mild discomfort during treatment (often described as tolerable without anesthesia)
- Rare risks include purpura, crusting, and temporary pigmentary changes 7
Contraindications
Active skin infection, uncontrolled diabetes, and tendency toward keloid formation are contraindications to laser therapy 7. Patients should avoid sun exposure and use broad-spectrum photoprotection before and after treatments 2.
Treatment Protocols
Typical Regimen
Most conditions require 3-5 treatment sessions spaced 4-8 weeks apart to achieve optimal results 7. This interval allows sufficient time for tissue repair and collagen remodeling between sessions 7.
Adjunctive Therapies
Combining laser treatment with topical platelet-rich plasma (PRP) immediately after each session can reduce post-treatment erythema and edema (p=0.02) and shorten recovery time, though it does not enhance final outcomes beyond laser alone 7. Topical PRP application is as effective as intradermal injection with better patient tolerability 7.
Clinical Evidence Quality
The evidence supporting various laser technologies, including 1064 nm systems, has evolved significantly over the past 20 years 2, 3. However, most laser studies remain small, unblinded, and observational with varying treatment protocols, limiting the strength of recommendations 6. The 2024 American Academy of Dermatology acne guidelines note that additional high-quality randomized controlled trials are needed for most laser-based acne treatments 8.
Important Caveats
- Laser safety requirements must be strictly followed, including appropriate eye protection for both patients and staff to prevent retinal damage from high-intensity light exposure 4
- Results vary based on skin type, condition severity, and individual patient factors 2
- Patient satisfaction rates are generally high (approximately 91% satisfied or very satisfied) across various dermatologic applications 7
- The device should only be operated by trained healthcare professionals familiar with laser-tissue interactions and appropriate parameter selection 5
