Allergan releases a new filler – Type V.

April 10th, 2009

Filler type V is now available at The Victorian Cosmetic Institute!
(Due to TGA restrictions, the full name of filler type V cannot be published.)

Filler type V is designed as a large volume filler, most suited to areas such as the cheeks or the chin. It is composed of hyaluronic acid, which is a substance that is naturally found in the skin. The filler is similar to other fillers produced by Allergan, except that this filler is slightly thicker than the other fillers, and thus is intended for deeper placement in the face to augment larger areas, giving superior results here.

The other potential advantage of this filler is that it will last for approximately 12-18 months.



Medlite vs Gemini laser

March 18th, 2009

The Medlite and Gemini lasers are two lasers that are commonly used at The Victorian Cosmetic Institute for the treatment of skin. Interestingly, they both emit the same wavelength, namely 1064nanometres and 532nanometres, but perform very different treatments simply because of the duration of each laser pulse.

The Gemini laser is a long – pulse laser, which emits pulses that are in the millisecond range. Although the term ‘long-pulse’ would suggest something much longer than a few milliseconds, this is quite long in the laser world.

The Medlite laser is a q-switched laser. This means that it emits pulses in the nano-second range. One nano-second is one billionth of a second and therefore is one million times shorter than one millisecond. The laser achieves this very short pulse via q-switching, which is achieved by a camera-shutter like mechanism in the laser.

The consequences of these differences in pulse duration are that these lasers are used for very different applications. The Medlite laser with its extremely short pulses tends to be able to provide very high energy short pulses that can shatter the target without heating it much. For example, it can be used to remove tattoo ink from skin by shattering it into smaller particles for the body to remove. The Gemini laser cannot perform this treatment because its relatively longer pulses cause heating and scarring of the skin before the tattoo ink can be broken down.

On the other hand, the Gemini laser is highly suited to the treatment of visible/superficial blood vessels on the face. Its 532nm wavelength is highly attracted to this target, and provides specific heat energy to this target to help to shut down the capillary. The Medlite laser at the same wavelength, although attracted to the target, tends to not provide enough heat energy to shut down the blood vessel due to its short pulse.
