What is Laser Hair Removal?
Laser works by using a direct light beam which goes directly into the hair follicle. This means there is much less chance of burning the skin. It had been performed experimentally for about twenty years before becoming commercially available in 1995 and 1996. It is far more efficient, and treatments done with the Cryo Sheer Aqua are virtually pain free.
Hair removal lasers have been in use since 1997 and have been approved for “permanent hair reduction” in the United States by the Food and Drug Administration (FDA). Under the FDA’s definition, “permanent” hair reduction is the long-term, stable reduction in the number of hairs.
Laser hair removal has become popular because of its speed and efficacy, although some of the efficacy is dependent upon the skill and experience of the laser operator, and the choice and availability of different laser technologies used for the procedure.
Some will need touch-up treatments annually, especially on large areas, after the initial set of 3-8 treatments
How it works?
The primary principle behind laser hair removal is selective photo thermolysis (SPTL), the matching of a specific wavelength of light and pulse duration to obtain optimal effect on a targeted tissue with minimal effect on surrounding tissue. Lasers can cause localized damage by selectively heating dark target matter, melanin, thereby heating up the basal stem cells in the follicle which causes hair growth, the follicle, while not heating the rest of the skin. Light is absorbed by dark objects but reflected by light objects and water, so laser energy can be absorbed by dark material in the hair or skin, with much more speed and intensity than just the skin without any dark adult hair or melanin.
Melanin is considered the primary chromophore for all hair removal lasers currently on the market. Melanin occurs naturally in the skin and gives skin and hair their color. There are two types of melanin in hair. Eumelanin gives hair brown or black color, while pheomelanin gives hair blonde or red color.
About the Device
The Cryo Sheer Aqua Diode Laser combines three wavelengths, 755 Alexandrite; 808 Wavelength & Yag 1064 all in one hand piece. The Sapphire contact cooling cools the dermis ensuring a pain free treatment. The Cryo Sheer is brilliant as it is so comfortable. It cools the skin gradually minimising the risk of burning. It is one of the safest lasers in the world. We use an “in-motion” technique, which means the head of the laser is constantly moving across the skin to ensure the skin never gets too hot. The Cryo Sheer also has the “Ice Tip” which is used to cool the skin, making Cryo Sheer Aqua unique and effective.
Why Three Wavelengths?
It combines 3 different wavelength (755nm+808nm+1064nm) into a single handpiece, which simultaneously work in different depth of the hair follicle to achieve better efficacy and ensure the safest and comprehensive hair removal treatment.
Alexandrite 755 wavelength delivers powerful energy absorption by the melanin, ensuring coverage on the widest spectrum of hair types and colour variations. With the penetration of the 755nm targeting the bulge of the hair follicle it is proven to be effective for the eyebrow and upper lip region.
808 nm Wavelength
The 808nm wavelength offers deep penetration of the hair follicle with moderate power and a fast repletion rate at 12mm X 12mm spot size for fast and efficient treatment. The 808nm has a moderate absorption level making it safer for darker skin types, targeting the bulge of the bulb of the hair follicle. This ensuring moderate tissue depth penetration and delivering excellence for treating areas such as arms, legs, beards & cheeks.
1064 nm Yag Wavelength
The 1064 wavelength offers the deepest penetration, on lower melanin absorption, allowing penetration to the bulb and papilla. This allows treatments to reach deep embedded hair such as pubic areas, scalp & under arms.
The combination of 755nm, 808nm & 1064nm wavelengths increases the thermal coverage for overall laser treatments for effective, comfortable and pain free laser hair removal. Ensuring better efficiency and excellent coverage by reaching different depths of the follicle.
Understanding IPL Laser Hair Removal
IPL (intense pulsed light) technology is technically not a laser treatment. It uses a broad spectrum of light with many wavelengths meaning it leads to unfocused energy around the hair and skin area. As a result there is much wastage of energy and less selective absorption in the follicle resulting in less effective destruction of the hair. Using broadband light also increases the potential for side effects such as burns or pigmentation, particularly if integrated cooling is not used. IPLs are typically only suitable for lighter skin types (1-3 on the Fitzpatrick scale) for the most part.
Understanding Diode Laser Hair Removal
The key to successful diode laser hair removal is the deliverance of high energy into the skin. The energy is selectively absorbed by the melanin surrounding the hair follicle whilst not impacting the surrounding tissue.
Diode lasers use a single wavelength of light that has a high abruption rate in melanin. As the melanin heats up it destroys the root and blood flow to the follicle disabling the hair growth permanently. High quality laser hair removal machines such as The Primelase HR and The Elysion incorporate crystal freeze refrigeration contact cooling (+5ºC) to protect the surface of the skin, making the treatment a comfortable, pain-free experience for patients. Diode lasers deliver high frequency, low fluence pulses and can be safely used on all skin types.
What’s the Difference between Diode Laser Hair Removal and IPL?
The treatment methods outlined above mean that, typically, IPL technology will require more regular and long-term treatments for hair reduction. A diode laser will work more effectively with less patient discomfort (with integrated cooling) while treating more skin and hair types than the IPL.
