Alexandrine – absorbed by melanin, Is (near Infrared) Is most effective when used on pale skin and Isn’t safe to use on darker skin. It is Mann visible light wave length. It has a pulsed dried array of 810 NM for pale to medium skin types.
Alexandrine has an observed color change from green to red.
Alexandrine results from small scale replacement of a aluminum by chromium Ions In the crystal structure, which causes Intense absorption of the light over a narrow range of wave lengths in the yellow region of the spectrum’ (Wisped) [http://en. M. Wisped. Org/wick/Chrysler/alexandrine] Alexandrine is a trochaic gem, which exhibits green, red, and orangey-yellow colors. Ruby- it Is deeper and Is 694. NM In visible wavelength and absorbed by melanin, and isn’t used for hair removal any longer as It Is only safe to use on clients with very pale skin. Ruby laser is a solid laser.
Its synthetic medium is ruby crystal. Ruby lasers use short pulses of red light. Diode – is a semiconductor laser that is electronically pumped. They have the largest wave length selection, emits Mann near Infrared wavelength OCW and Is absorbed by melanin. Laser diodes are continuously emitting diodes from infrared to red, green or blue. Pulsed laser diodes or Plus have wavelengths of Mann and annum. Mann are single emitters. annum are eye safe. A diode is a semi conductive metal which allows energy to travel In one direction. An : Wag ? a crystal, and the most common form of laser.
They typically emit a light wave length of annum in the infrared. They can operate in continuous or pulsed mode. These lasers can be used to treat numerous medical conditions such as ophthalmology, cataracts surgery, acute angle-closure glaucoma, benign or malignant lesions, skin cancers, as well as hair removal or vascular defects. Wag lasers have been used in manufacturing such as engraving and etching. PL – or intense pulsed light, shoots 2 or 3 pulses at the same target with a specific delay between the pulses. The spot size or width of the laser beam affects treatment.
Theoretically, the width of the Ideal beam Is about 4 times as wide as the target Is deep’ (Wisped). PL use effluence or energy which is measured in joules. Epidermal cooling with the PL means that higher fluencies can be used and treatment is less painful. Light Heat Energy (broadband spectrum systems) – light is converted into heat which targets various chromospheres In the skin, such as hemoglobin, melanin, and water. ‘Definition – Intense pulsed light describes the use of Intense pulses of non-coherent light distributed over a range of wave lengths from Mann to annum for removal of hair and other purposed.
A related, but distinct technique is hair removal; the primary deference Is that laser treatments uses generated coherent ND monochromatic light’ (Wisped). Question 2 – Investigate the various methods of skin cooling in relation to laser and I OFF Cooling gels are water based and are applied to the skin pre-treatment and where necessary after treatment. The gel works by evaporation. Ice packs may be applied to the area pre and post treatment, but not directly to the skin as ice burns can occur, Wrap the ice pack in a thin disposable covering like bed roll.
Cryogenic sprays or cold air is generated and directed to the area of treatment. Both are pre and post treatment. Cryogenic cooling is built into some systems. Simultaneous contact cooling is available on systems that operate through a scanner. It facilitates pre and post treatment cooling, and simultaneous cooling with lasing. This method speeds up treatment time by a series of laser pulses emitting in quick succession in a controlled area. Question 3 – describe the recommended time intervals between treatments for each are and give reasons for this.
How do you evaluate the effectiveness of the treatment. Investigate reasons for poor hair removal results. Describe the recommended time intervals between treatments for skin rejuvenation and give reasons for this. It is necessary that subsequent treatments are given at regular intervals. The hair needs to be at the engage stage of growth for optimum results to be achieved. Time intervals are normally as follows: Area Eyebrows Upper lip Chin Armpit Legs Arms Bikini Retirement in weeks 5-7 3-5 6-8 6-12 8-10 Engage is the active growth state of the hair cycle.
The follicle has reformed, the hair bulb is developing surrounding the dermal papilla and new hair forms growing from the matrix in the bulb. ‘Because of the cyclical nature of hair growth the follicles are always at different stages of their own growth cycle. When hair is removed, therefore, the hair will not grow back at the same time. For this reason, waxing or threading can appear to reduce the quantity of hair growth. ‘ (the Foundations Beauty Therapy 2 by Lorraine Mormon). Evaluating the effectiveness of the treatment can be accessed through photographs.
It is good practice to take photographs before and after each treatment. Treatment records keeping notes on progress and observations. Client feedback is essential for evaluating the effectiveness of the treatment. Clients can provide information such as how often they are shaving, if the hair is feeling finer, hinging out or if the hair is no longer growing back. Some of the reasons for poor hair removal results could be that the client has in increased amount of melanin in the skin causing lower energy effluence or Joule setting.
The hair growth cycle may not be at the engage stage meaning that the hair is not active. It could be at the telling or cottage stage. The client may have topical hair removal between treatments. Adapted for each individual client. Clients may have tattoos. We do not work over tattoos as the pigment of ink may heat up and cause a burn or reduce in color or quality. We can use a white pencil or void the area. Clients skin types and hair color effect how each treatment is adapted, as the lighter the skin the lower the melanin content and the darker the hair is the higher the melanin content.
Therefore, the best results are on a light skin with a dark hair. We can increase or decrease the pulse effluence and Joules to suit the clients skin type and hair color. Question 5 – Give a personal reflection on how you have felt from the start of using laser/lap to how you feel on going out into the industry. You can include how you feel you have developed and how it will affect you in the future. When I first started working with lasers all of the information was quite scary, it wasn’t until I started to break down every piece of information that I began to understand how and why PL and lasers work.
I have been working out in the industry with PL and used various pieces of PL machinery with companies such as Crystal Medical, Linton, Pulsar and Skin First. I have found some equipment to be more effective than others. The most effective machine I have found to be in the Linton Illuminate Advanced which is currently used by the NASH. Using a piece of equipment that is being used by the NASH instill confidence in me, and also in my clients because if the NASH are using such a piece of equipment, in my mind it would be deemed to be medically compliant, tested, reliable and give effective results.
In the future I would like to see a more efficient method of hair removal or perhaps a machine that can cover a large area in each treatment. I would also like to see the regulations on who can use PL or laser machines tightened as currently anyone can have independent training via the companies who supply the machines over a couple of days. I believe this is not enough knowledge or experience to be let loose on members of the public.
