Treatment of Meibomian gland dysfunction (MGD) 
A safe and effective treatment for all skin types.
Simple and fast treatment  (<5 min)
Several studies detail the mechanisms of action of IPL systems: :
Neurostimulation of the parasympathetic nerve pathways[1,2]
Tear production is stimulated by the nervous system, via the parasympathetic nerve [3], which is linked to bath the lac rimai gland [3,4] and the meibomian glands [3,5].
Faster meibomian gland metabolism [1,2,3,4,5]
lncreased meibum expression due to heat [6].
Small vessel coagulation: acts against inflammation of the skin (rosacea) and eyelids (blepharitis) [7,8,9].
Reduces Demodex mites.

The expected results of IPL treatment may include [6]:

lmproved tear film quality. 
Patient-reported improvement in the following symptoms: dryness, sensation of foreign body in the eye, itching, burning, eye fatigue, blurred vision, sensitivity to light, watery eyes, impaired secretion, pain.
Additional effects of IPL treatment may be observed:
- Pain relief
- Anti-inflammatory action (blepharitis, conjunctivitis, rosacea)
- Reduction in inflammatory markers (cytokines) in the tears [10]
- Antimicrobial action (bacteria and Demodex mites).
An IPL device is a generator of polychromatic intense pulsed light.
The LacryStim light spectrum extends from 610 nm to 1200 nm.
LacryStim uses a 610 nm filter that blacks UVA, UVB and UVC rays.
Thanks to this 610 nm filter:
- The melanin in the skin absorbs less light [11]
- No phototyping is required
- All types of skin can be treated, including black skin (Fitzpatrick scale phototype VI).
The total energy is between 8 and 12 J/cm2 and is delivered in a sequence of pulses.
The time between each pulse respects the thermal relaxation time (TRT) of the skin, thus limiting:
- The increase in tissue tempe rature
- Thermal damage to the skin
- lnflammatory reactions
- The phototyping required.



A single handpiece, no additional kit required.

Integrated water cooling.
Does not burn the skin.
Applies a thin layer of gel during treatment.
Long-lasting flash lamp.
Delivers the same energy level from first to last shot.



SESSION 1 : Day 0

SESSION 2 : Day 7 to  15

SESSION 3 : Day 15 to 30

SESSION 4 : Day > 30 Optional


Short session A few minutes

Thin layer of gel 

Series of 4 shots Between the cheekbone and temples
