From the manufacturer

The best at-home hair removal system is now even better! The Silk'n Flash&Go Long Life Upgrade Kit is a revolutionary cartridge that will provide a lifetime of flashes, for use with the Silk’n Flash&Go device (sold separately). The redesigned Flash&Go cartridge provides a 'Lifetime' of flashes for a 'Lifetime' of hair removal results. This will be the last cartridge you will EVER have to buy!

How Flash&Go’s proven effective technology works

Silk'n Flash&Go uses patented Home Pulsed Light (HPL) technology to emit gentle pulses and target hair follicles at the root to disable future hair growth. Every hair in our body goes through the three phases of the hair growth cycle: Anagen, Catagen and Telogen. These phases have an important impact on how the process of light-based hair removal works. Anagen is the hair growth phase while Catagen and Telogen, are both resting phases. At any given moment the majority of the hair follicles in any skin area are in the resting stages. These resting hairs cannot be affected by laser or light hair removal treatment, however hairs in the growing Anagen phase will respond. It is therefore important to understand that it may take a full hair growth cycle to achieve complete results when doing any energy based hair removal. Keep up with treatments and you will be on your way to silky smooth skin!

Who can use it?

If you purchased a Flash&Go from an authorized dealer after January 2014 then your device is compatible with this upgrade. If you purchased a Flash&Go at a retail location or on another website then your device may or may not be compatible with this upgrade and you will need to contact customer care to inquire. Avoid using on naturally dark skin complexion or recently tanned skin. This beauty tool is ideal for use with lighter skin tones (I - IV on the Fitzpatrick Skin Tone Classification Scale- please see skin tone chart to the right) and brown-to-black hair. If you have blonde, grey or white hair then there is a lack pigment in the hair and you are not candidates for treatment. For additional safety, Flash&Go cartridge has a built-in smart sensor that detects if skin tone is too dark for treatment and will not pulse if the skin has too much pigment for treatment. This Flash&Go cartridge is to be used with the Flash&Go device and is designed for use on legs, arms, underarms, bikini line, face and other areas of the body where hair removal is desired.

When will I see results?

With just two to four self-treatment sessions, most users experience visually diminished hair that is comparable to results produced by professionally administered laser procedures. User satisfaction and clinical results speak for themselves: 80% of users experienced a noticeable reduction in hair after 3 months. 90% preferred using HPL to visiting a spa or salon. 90% said they would recommend HPL to a friend. 90% described HPL as convenient, easy, useful, and innovative.
