Cuticle Medulla Cortex Fig 3 Section of human hair Within the skin Fig 4 the hair shaft is surrounded by a hair sheath and is connected to the hair root which is embedded in a pit in the skin called the follicle The root is nourished by a small artery in the papilla The follicle is typically located between 1mm and 5mm under the surface of the skin This depth is dependent on the body site 1mm on upper lip 5mm on bikini line Follicles are often placed in groups of three see Fig 5 Normally only 1 of the 3 follicles is in the growing phase at any one time Page 12 1MAN8219 C08 ENG Ellipse IPL Clinical Workbook Anatomy Inner Root Sheath Outer Root Sheath Hair Bulb Fig 4 Cross section of hair in Fig 5 Hair follicles skin placed three together 2 6 Hair growth The life cycle of the human hair has four phases Normally the hair follicles are not synchronized and therefore hairs in close proximity to one another may be in different phases at the same time However hormonal influences following a birth or severe infection may cause synchronization of the hair growth cycle The four growth phases are e Anagen phase the growing phase of the hair During early anagen new hair grows from the hair follicle pushing out old hair from the hair shaft e Catagen phase the hair bulb is degraded cell growth and melanin production stops and the hair bulb is moved upwards to the skin surface e Exo

Clinical Workbook Treatment factors determined by system used Ellipse Light SPT operates only in normal mode This means that the Ellipse system calculates the TRT based on the entered treatment parameters and configures the pulse time setting accordingly With 1 PL and MultiFlex a suitably trained and experienced user can over ride the pulse times suggested by the system Guidance for these series users on how to make minor adjustments to the pulse time and the effects of using too long or too short a pulse will be detailed for each treatment type in the subsequent chapters Energy setting J cm When a target absorbs the emitted light the light energy is converted into heat resulting in an increased temperature in the target When running in normal mode the Ellipse system calculates the required treatment settings based on the entered patient parameters skin type degree of suntan chosen treatment procedure and the size or colour of the target and the system configures the energy level and the pulse time accordingly The energy level stated on the screen in J cm is always the total amount of energy reaching each square centimetre of the skin surface each time the applicator is fired When treating larger targets a single pulse of light is used but for small targets such as pigmented lesions the system will fire a double pulse of light with a short interval separating the pulses In this case the total energy level is the

16. I PL The treatment of pigmented lesions such as solar lentigines or ephelides is based on selective photothermolysis The aim of treatment is to destroy the excess pigment existing in the skin tissues without damaging the surrounding tissue To do so we need to know e The target chromophore e The wavelengths to be used e The pulse time e The correct energy The target chromophore The target chromophore when treating a pigmented lesion is melanin Melanin is produced in epidermal cells called melanocytes specifically in a part of the melanocyte known as the melanosome It is then stored in the keratinocytes Keratinocytes are destroyed if exposed to heat at 70 C for more than 1ms Wavelengths to be used The absorption curve Fig 17 shows that melanin absorbs light in the visible and near infrared spectra The light used must penetrate the skin at sufficient depth to destroy the pigment and at the same time cause minimum damage to the surrounding tissue Wavelengths from 400nm to 950nm have a good absorption by melanin and no absorption by the competing chromophore water Absorption is particularly good in the region 400nm 720nm The competing chromophore oxyhemoglobin is removed from the target area by compressing the cutaneous vessels This is achieved by pressing the applicator down on the skin surface 1MAN8219 C08 ENG Page 73 Ellipse IPL Clinical workbook Pigmented lesions The pulse time Treatment of

Note that the treatment intervals in the table above are general but optimal It is possible to get good though not optimal results with shorter treatment intervals The very best results are obtained if a patient makes an appointment for a subsequent treatment as soon as she notices the appearance of new hair Note that treatments on male back are unlikely to give total success unless the patient is aged around 30 35 years or older This is simply because until the age of 30 35 new hair will be created by hormonal changes as part of the aging process For male patients under aged 30 it is recommended to offer hair management a treatment of the existing hair approximately 2 or 3 times per year Page 50 1MAN8219 C08 ENG Ellipse IPL Clinical Workbook Hair removal Hair guidance To increase the rate of success it is important that you select the patients with care Start your first treatments with fair skinned patients with dark hair and initially avoid the more difficult patients with darker skin more pigmentation and blond light red or grey hair Default settings Inexperienced users are recommended to start by using the default settings which are calculated by Ellipse I PL systems after entering the clinical parameters The standard default settings are safe settings with low risk of adverse effects The default settings do not guarantee optimal results since they are placed in the lower end of the therapeutic window This is th
18. To achieve selective photothermolysis three parameters must be controlled e The wavelength or waveband of the light is selected so that the light energy is absorbed by the chosen chromophore e The duration of the light pulse is selected to ensure the target is lethally damaged with minimal conduction of energy into the surrounding tissue e The right energy level is chosen to create enough heat to lethally damage the target within the given pulse time By controlling these three parameters selective destruction of the target chromophores can be achieved without injuring the surrounding tissue Page 22 1MAN8219 C08 ENG Ellipse IPL Clinical Workbook Light tissue Interaction L andas Nd ve Ruby Diode Absorption linear scale CN 00 400 500 600 700 800 900 1000 1100 1200 Wavelength nm Fig 16 Absorption spectra of chromophores showing commonly used lasers for treatments The xenon lamp of an IPL system emits a wide spectrum of different wavelengths at the same time from approximately 240 1200nm This light is then filtered to match different applications Two different types of filtering can be distinguished e Single mode filtering as used in the first generation intense pulsed light systems These systems use a coloured filter to remove energy below a given wavelength on the left side of the absorption curve Depending on the type of filter the emitted light typically starts somewhere between 510 and 720nm
