Pulsed Dye Laser V Beam II

The pulsed dye laser is a dye laser with a wavelength of 595 nm. It is readily absorbed by the hemoglobin in the blood and is effective on lesions where blood vessels are dilated or proliferating.

At our clinic we use CANDELA’s V Beam II. Irradiation for red birthmarks such as capillary malformations and infantile hemangiomas is covered by insurance, and it is sometimes used to treat common warts (viral warts) and venous lakes. In aesthetic dermatology it is also used to improve facial redness and acne scars and for rejuvenation.

Features of the V Beam II

Selectively absorbed by hemoglobin

The laser light is selectively absorbed by the hemoglobin in the blood, and in a lesion where capillaries are clustered, the hemoglobin absorbs the laser’s light energy and converts it to heat, thermally destroying the inner walls of the vessels and occluding them.

Treatment with high irradiation energy is possible

The maximum irradiation output is higher than in conventional devices, enabling treatment with higher irradiation energy.

Little bruising

Because the pulse width is composed of eight micropulses (subpulses), safer treatment with reduced side effects such as purpura formation is possible.

Cooling reduces burns

The skin is protected by spraying a coolant just before the laser is applied.

Conditions for Which the Pulsed Dye Laser Is Indicated

• Capillary malformation (insurance covered)
• Infantile hemangioma (insurance covered)
• Telangiectasia
• Common warts
• Spider angioma
• Venous lake
• Acne scars
• Hypertrophic scars and keloids
• Rosacea

and others

The V Beam II in Aesthetic Dermatology

The pulsed dye laser V Beam II responds to red lesions. It is effective on fine blood vessels around the sides of the nose, the type of rosacea with clearly dilated vessels, red scars from acne, and red, raised hypertrophic scars and keloids.

Also, regardless of redness, applying it at low fluence (weaker power) has a rejuvenation effect, which we call V Beam Facial.

V Beam Facial

When the V Beam II is applied, it causes slight thermal damage within the dermis and activates fibroblasts, so elastin and collagen are rebuilt in the upper dermis, and a rejuvenation effect is said to be obtained. The effect differs with the location and depth of the wrinkles and the skin type. Also, because the 595 nm wavelength acts selectively on melanin pigment as well, an effect on shallow spots can also be expected. We recommend applying it to the whole face, but it can also be applied to specific areas.

The treatment is repeated four to six times at intervals of once every four weeks. After that, we recommend maintenance every six months according to the condition of your skin.
