Biology:
What causes the pain?
Skin is very sensitive to outside influences due to a high number of
different cutaneous receptors, such as:
• Thermoreceptors
(for heat)
• Mechanoreceptors
(for mechanical stress)
© Copyright Quantel Derma GmbH 2011
2011-03-14_Master and Sales Presentation LEDA_Rev10
Pain Reduction at Hair Removal
Pain level is dependent from
Pain reduction can be achieved by
• Level of external nerve
stimuli
• Decreasing the external
nerve stimuli (= less heat!)
• Number of stimulated
nerves at the same time
• Decreasing the influenced area
(= smaller spot size!)

Principles of Low Fluence Hair Removal
(= less heat) with LEDA EPI
Options for low fluence
treatments
Advantages (+) and
Disadvantages (-)
•
Treatment of skin with
fluence of less than 12 J/cm2
(e.g. Lumenis LightSheer
Duet)
+
+
-
•
Energy is not delivered in
one shot or path but in
several paths
(e.g. IN-Motion™
technology from Alma)
+ Applicable for tanned skin
- Uncontrolled procedure
- Time consuming
Lower pain level
No Cooling required
Bad results on fine hairs
No long-term efficacy proven
Low fluence is a good option for tanned and sensitive skin to remove
thick hairs

2011-03-14_Master and Sales Presentation LEDA_Rev10
Low Fluence Hair Removal with LEDA EPI
• Low fluence (6 – 12 J/cm2) can be applied with short pulse durations
• Efficacy: multiple spots with low fluence for gentle heating up of the
hair bulb, surrounding tissue can cool down between spots
• Full control of energy and stacking

The Effect of Spot size
LEDA EPI distance holders
Experience by many patients
with sensitive skin
Small spot size is less painful than
large spot size using the same
parameters (fluence and pulse
durations)
Small spot 10 x 12 mm
e.g. for upper lip
Large spot 50 x 12 mm
e.g. for legs and backs
How can the lower pain of the small spot be combined with the high
speed of the large spot?
