General Information
Early history
In the 1960s, use of lasers on the skin's surface for the removal of hair and for other medical purposes was first explored. Argon lasers were the first to be tested as a means of hair removal. Researchers and physicians like Dr. Leon Goldman pioneered the use of lasers in medical applications, particularly hair removal, and the development of the q-switched laser is attrubuted to Dr. Goldman.
From the 1960s through the 1990s extensive research was performed to develop the technology into what specialists use today. Energy wavelengths, pulse durations and intensity levels were carefully researched and refined. Side effects were minimized and efficacy increased. Researchers and technicians added photosensitive (light-absorbing) carbon dyes late in the 1990's, dramatically improving the rate of photon thermal exchange (conversion of radiation into heat) and making the procedure more effective and reliable on light colored hair growth.
Modern laser hair removal techniques are the result of years of medical technolog and advancement. With the endorsement of the FDA and thousands of satisfied patients, laser hair removal is a good option to consider for those looking into permanent hair removal.
Types of lasers
- Alexandrite - such as the Candela GentleLase Plus.
- Ruby - such as the EpiTouch or the Epilaser.
- Diode - such as the Coherent Light Sheer.
- ND and LP ND Yag - such as the Candela GentleYag and the Altus Cool Glide.
Factors
- Pulse length - long pulsed lasers are considered safest.
- Fluence - Selection of energy levels can be varied for skin type.
- Delay - The time between pulses of light affects how much the skin and hair follicles are allowed to cool off.
- Spot Size - Affects the speed and penetration of the laser. A larger spot penetrates deeper. A good selection of spot sizes helps the technician reach the hair at the depth at which it grows.
- Cooling - The surrounding skin may be protected by a gel, spray, or cooled tip pressed against the skin.
Emerging laser technologies have made it possible for people with many skin and hair color combinations to enjoy the benefits of laser hair removal. These lasers have been designed to ignore the melanin in the skin and to safely treat patients of all skin types. Having said that, the most successful results are those patients with dark hair and light skin--light skinned, dark haired patients will have a more significant result than patients with blond or red hair or patients with darker skin and will need fewer treatments for a more permanent hair reduction. It is best to consult with your specialist to see which laser system is best for you.
Advantages
- Research has proven that it is also a safe and effective method for hair removal.
- It is considered safe when performed properly by an experienced provider.
- Light-skinned, dark haired consumers experience best results.
- Re-growth is often lighter with finer texture.
- Because the laser method is quicker than electrolysis, it is especially useful for large areas of hair removal in one sitting.
Disadvantages
- The procedure requires eye protection.
- The procedure can be expensive.
- It is not as effective on darker skin tones or on persons with gray, red, or blonde hair.
- Improper treatment or overexposure to laser light can cause burns, lesions, and long-lasting skin discoloration.
- Re-growth can be patchy or patterned.
- Because regulations vary, inadequate control methods to ensure competent practitioners exist.
- Some persons find the treatment painful.
- Some persons, even those determined to be a good candidate, do not respond well to treatment.
