Candela: Gentlelase, Smoothbeam, Vbeam > GentleLase cryogen settings

What settings are recommeneded for the DCD spray? We've used 70/50 for several years now with good results but recently were told we should be using 40/40 for most people (50/40 if darker or don't tolerate the 40/40). Since we purchased the unit used, Candela is of no help. The manual that came with it is confusing. In one area is says we should use 80 msec spray for the 18 mm tip but an addendum lists a variety of acceptable settings 40/40, 50/40, etc.

I've been using mainly 50/40 for LHR and none for tx of brownspots on light skin.

Word of advice...do not use Gentle Lase for brown spots on someone with darker skin....

i have used the gentlelase for 3 years+. i am based in hong kong.

For LHR, even for chinese ort indian skin types, i used dcd 30-50 / 20-30, with no problems so far.

Tell u what, i also used it for all pigmentation problems with damn good results and no problems at all. I am taking about at least over 500 cases, if not near 1000. These include freckles, solar lentigo, and general sallowness / mottleness. Just dont use it for melasma. So Lori, what are u talking about?

Dr stephens:

I have almost all light caucasian patients andt therefore haven't had to really use dcd for dark sunspots. what kind of dark spots are you treating on asians (sunspots? moles? dark moles?) and what spot/fluence are you using? THe one time I tested it out on my leg for a small hyperpigmented spot, I just made it darker and worse. I can't remember the setting I was experimenting with. I appreciate your advice.

jmd,

I use DCD onlyfor LHR, never for any pigment removal.

Lets say a person with dispersed freckles with with some solar lentigines, I do it in 2 to 3 rounds:

1. 12 mm 10 - 12 J/cm2 - whole face
2. 12mm 14 - 16 J/cm2 - whole face
3. 8mm 20 - 25 J/cm2 - to spots

all depend on the skin darkness / spot darkness ( i.e. contrast ) and the immediate "greyish" responses.

The first 1 - 2 rounds aim to even out the background colour for the whole face, and the final blast to erase the pigment.

For the above example I expect ~ 90% improvement for freckles and ~ 50% for solar lentigines, overall anything from 70- 80% improvement.

This is NO advice, just exchange of opinion and experience. We just learn from each other.

Thanks

dr. stephans:

thanks for the exchange of ideas. I will use myself to test out your settings and let everyone know how I do. I assume you space the treatments out 3-4 weeks? ANd is it safe to treat asian skin until you see the greyish response? thank you for your input.

I would never use more than 50-50 DCD unless I was spot-treating a venous lake or some other bizarre application for the GentleLASE. For laser hair removal, I use 40-40 DCD for EVERY patient. If I'm using a fluence less than 10J/cm2, I turn it down to 30-30. I have seen more post-inflammatory hyperpigmentation from cryo than from the laser energy itself.

Also, if I caused greying in an asian patient, I would expect to see post-inflammatory hyperpigmentation that lasts between 2 and 12 months.

07.7 | Unregistered CommenterlaserPA

From the beginning I was using 40/40 as everyone else does. Then I started to experiment and today I only work with 30/20, why? If you use 40/40 the cryo will cool down deeper layers of the skin and this is not good when removing hair in the face where most of the hair-follicles are shallow (especially on the upper lip). I can see much better permanent results with 30/20.

40/40 can be used on darker skin types (4+ and 5), you can also try 50/30.

I have been using the mini GL for 12 years...i use to use 40/40 cryo as they advise...there is no use in doing that, and it gives more hyper pigmentation than anything else.

I now use 20/20 for years now, on my GentleLase and my GentleYag, and its perfect. This is all for Laser Hair Removal.
