Vascular lesions clear by selective photothermolysis. You deliver light at a wavelength haemoglobin absorbs more strongly than the surrounding skin, with a pulse long enough to heat the vessel through but short enough that the heat does not spread. Get the wavelength or the pulse duration wrong and you either leave the vessel intact or you burn the skin above it.
Wavelength follows vessel depth and size
Oxyhaemoglobin absorbs strongly in the green-yellow range, around 540 to 580nm, and again, more weakly, near 1064nm. That gives you two working ranges and they do different jobs.
- Fine superficial telangiectasia, facial capillaries and small spider veins respond to green light. Absorption is high, penetration is shallow, and precision matters more than depth.
- Larger, deeper vessels, reticular veins and leg veins need 1064nm Nd:YAG. Absorption is lower, so you need more energy, but the light reaches vessels the green wavelengths never will.
- Diffuse redness and rosacea is not one vessel, it is a field. Narrow-band IPL covers area efficiently where a pen-sized spot would take all afternoon.
What Alma puts on the platform
On Alma Harmony these are three applicators on one system rather than three machines:
- VascuPen, a pen-shaped green diode laser for precise, comfortable treatment of superficial vascular and pigmented lesions.
- ClearVas, long-pulsed 1064nm Nd:YAG. Absorption by haemoglobin combined with deep penetration makes it the workhorse for vascular lesions on the face and body.
- Iris Dye-VL, a narrow-band IPL restricted to the wavelengths that melanin and haemoglobin actually absorb, which is what makes it usable on darker skin where broadband IPL is not.
Skin type changes the calculation
Melanin competes with haemoglobin for the same light. On Fitzpatrick IV to VI the epidermis absorbs a meaningful share of any green or broadband pulse before it reaches the vessel, which is where burns and post-inflammatory hyperpigmentation come from. Two things reduce that risk: moving to 1064nm, where melanin absorption is comparatively low, and using narrow-band rather than broadband IPL. Patch test and treat conservatively regardless.
What to compare before you buy
Ask four questions of any vascular device. Which wavelengths does it actually offer, not which indications are listed on the brochure. What spot sizes, because a 1mm pen and a 15mm handpiece are different businesses. How is the epidermis cooled during the pulse. And what happens when you need a second wavelength, which for most clinics is a year or two after the first purchase. A platform answers that with an applicator; a single-purpose machine answers it with another machine.
Who can operate one in Australia
Vascular lasers are Class 4 devices and the rules are set state by state rather than nationally. Some states require licensing or registration and a nominated laser safety officer; others rely on documented training and a written safety plan. Alma Lasers Australia takes each clinic through what applies in its state before installation, and every installation includes on-site clinical training. See laser and IPL regulations.
Buying from the manufacturer
Alma Lasers Australia is Alma’s own Australian subsidiary, not a reseller, and covers New Zealand from Sydney, so training, service and parts come from the team that sold you the system. We do not publish list prices, because the configuration depends on which applicators your clinic will use. Bring your treatment prices and weekly bookings to a demo and we will build the numbers with you. Equipment finance is available through Medfin.
