BACKGROUND AND OBJECTIVES: In a recent case study, the use of a suction device to aid in port wine stain (PWS) laser treatments showed favorable results. It is our objective to further understand the mechanisms of vacuum-assisted laser therapy by analyzing the mechanical and optical changes of the skin and musculoskeletal tissues during the application of mild vacuum pressure from a suction cup. STUDY DESIGN/MATERIALS AND METHODS: A mathematical model of tissue deformation was used to determine the changes in tissue morphology that affect the underlying laser-tissue interactions, such as epidermal stretching and thinning, blood vessel dilation, and change in blood vessel depth. Video imaging experiments were used to verify the bulk tissue deformation and skin surface stretching computed by the mathematical model. Additionally, visible reflectance spectroscopy was used to determine the changes in the optical characteristics of tissue, including blood vessel dilation and epidermal absorption coefficient. RESULTS: At a vacuum pressure of 50 kP(a), the epidermis at the center of the suction cup was measured to stretch 4% and was calculated to be thinned approximately 6%. Blood vessels embedded in the dermis were measured to dilate up to two times their original size. However, these vessels were calculated to be displaced toward the skin surface by a very small amount, approximately 1-3 microm. The absorption coefficient of the epidermis was also measured to be reduced significantly by approximately 25% at a wavelength of 585 nm. CONCLUSIONS: Mild vacuum pressure applied to the skin surface causes considerable changes in the morphology and optical properties of the tissue. These changes may be used for more efficient photothermolysis of small PWS blood vessels.

Hey, man!

I'm emailing Mexco right now because he did something like this! I'll see if I can get him to post!

results from another study...

Results: Selective removal of stratum corneum was observed using the mobile mode of
microdermabrasion. In rhesus macaques, increase in the number of passes (10, 30, 50 80
and 100 passes) led to an increase in the degree of stratum corneum and epidermis
removal (vacuum pressure = 50 kPa). At 50 passes, selective removal of stratum corneum
was observed with little damage to the epidermis. Quantitative measurement
demonstrated that at 50 passes, greater than or equal to 25% of the skin had stratum
corneum removed, and only less than 25% of the skin had epidermal loss. Similar effects
were observed for human volunteers using a vacuum pressure of 25 kPa. This suggests
that with the mobile mode of microdermabrasion complete removal of stratum corneum
can be achieved with minimal damage to the epidermis.
Using the stationary mode, selective stratum corneum removal was not observed.
In rhesus macaques, microdermabrasion at 30 kPa and 50 kPa vacuum pressures each
with a skin-contact time of 3 s and 6 s did not result in stratum corneum removal.
However, blister (separation at the epidermal-dermal junction) formation was observed at
the 50 kPa condition. Similar effects were observed for human subjects at a vacuum
pressure of 30 kPa and 45 kPa, each with a skin-contact time of 3 s. In humans, the
blisters were observed at both 30 kPa and 45 kPa conditions.

I only use it like 2 days, it was not strong enough and it was noisy, but i believe that may help, it increase blood to the affected area, depending of the pressure, but if you leave it for more than 3 minutes it can create a mark that will last few days.

here are some pics.

This is the new device, is much more stronger, you unly need your mouth to make it work, i think its a great cheap device, patent pending:

Some times simple things are much better.

Hey mexco, i see your device is one of the cellulite devices. I more so want to make one that covers the whole mpb area but im not wether that one you have would work with a much larger suction cap. (pressure may be reduced etc)
