Laser resurfacing is not a one-device-fits-all decision. Depth of damage, scar morphology, pigmentation risk, and tolerance for downtime all influence treatment selection. Among ablative resurfacing technologies, UltraClear and Erbium YAG laser are frequently compared.
Both target water within the skin and stimulate collagen remodelling. However, their delivery systems, intensity profiles, and recovery timelines differ in clinically meaningful ways.
UltraClear operates at a 2910 nm wavelength using fibre-based fractional technology. It creates controlled micro-ablative columns within the epidermis and superficial dermis while preserving surrounding tissue.
Because energy delivery is rapid and precisely dispersed, collateral thermal spread is reduced compared with traditional ablative platforms. This often translates to shorter recovery and improved comfort when treating mild to moderate texture concerns, early wrinkles, and acne scarring.
Depth and intensity can be adjusted according to indication.
Erbium YAG lasers emit light at 2940 nm, a wavelength highly absorbed by water. They produce precise ablation of the epidermis with limited thermal diffusion compared with CO2 systems.
Erbium YAG is particularly effective for deeper rhytides, defined atrophic scars, and more advanced photodamage. However, depending on treatment depth, recovery may extend from several days to over a week. More aggressive passes require structured aftercare and temporary social downtime.
| Feature | UltraClear | Erbium YAG |
|---|---|---|
| Wavelength | 2910 nm fibre-based | 2940 nm |
| Delivery Mode | Fractional micro-ablative columns | Ablative resurfacing (fractional or full-field depending on system) |
| Best For | Mild to moderate acne scarring, fine lines, texture refinement | Deeper wrinkles, defined boxcar scars, advanced photodamage |
| Downtime | Typically several days depending on intensity | 5–10+ days depending on depth |
| Comfort | Generally well tolerated with topical anaesthesia | May require stronger anaesthesia depending on depth |
| Intensity Range | Adjustable, often positioned between non-ablative and fully ablative systems | More aggressive resurfacing capability |
| Pigment Risk | Reduced thermal spread may lower risk when appropriately selected | Careful parameter selection required, particularly in darker skin types |
Effectiveness depends on indication rather than brand.
UltraClear often suits patients seeking collagen stimulation and measurable improvement without extended recovery. It bridges the gap between lighter non-ablative treatments and fully ablative resurfacing.
Erbium YAG may be more appropriate for patients with significant dermal damage, deeper wrinkles, or sharply defined atrophic scarring where greater tissue removal is required.
In some cases, staged or combination approaches yield optimal outcomes.
Laser selection should follow anatomical assessment, not marketing claims. Skin thickness, scar depth, pigmentation risk, inflammatory history, and lifestyle constraints all guide decision-making.
At Dr Joney De Souza’s London clinic, consultation determines whether controlled fractional resurfacing or more aggressive ablation aligns with long-term aesthetic goals.
UltraClear and Erbium YAG are both valuable tools. The defining factor is not which laser is “better,” but which is biologically appropriate for your skin.
