Physician Clinical Exchange > carbon powder laser peel

Is anyone doing carbon powder laser peels with a Nd:Yag? How are the results? I've heard that this is very popular in Asia for lightening the skin and improving pore size/texture, so much that patients do it monthly to replace their facials.

you use the carbon lotion to incubate the face for about 20 minutes.
Then you use q-switched laser to do the min peel.
if you have someone with acnes, you can apply thicker coat, and it works quite well.
However, as it is a carbon lotion, do remember that using q-switched, the residual carbon particles may stick to your q-s lens or optics. Makes sure you clean the len / optics regularly, or you will face a very expensive repiar.

In theory the black carbon particles convert light energy from QS ND:YAG laser beam into heat, causing microdamage to the skin. QS ND:YAG can't heat up the skin due to its extremely short pulse width.

Carbon assisted Q-Switched ND:YAG may be used for facial skin rejuvenation or hair removal. But recent Taiwanese researchers found improved skin texture in both groups (with / without carbon assistance) and there was no difference between the two groups. Because of the problems with the carbon as mentioned in c.lee's post, I would use QS ND:YAG without carbon. The end point is transient very mild redness of the skin.

A cosmetic surgeon in Melbourne uses carbon assisted QSND:YAG for hair removal. I tried 2 weeks ago (first treatment) and found the hair growth is very very slow. It's too early to say if it can permanently stop hair growth yet.

Regarding carbon lotion, I made my own. I tried to mixed carbon powder with baby oil (mineral oil) and also water. I found carbon powder in water is better.

I'm also thinking of painting the skin with traditional Chinese black ink (for calligraphy). Because it's black and it adheres to the skin, it can convert light energy to heat, causing skin peeling. It may produce better peel than carbon assisted.
Also it's not carbon particles so it shouldn't cause damage to the lens (filters).

A caveat to using carbon powder is that the powder flies off the face when struck with Q switch 1064 ND Yag. Inhaling such carbon powder may lead to lung disease. Carbon particle is a carcinogen which may be deposited in the lungs over prolonged exposure. If the Taiwanese researcher agreed that carbon powder VS no carbon powder produce the same result, why even risk the chance of lung cancer for both the patients and physicians.

The title of the article is Skin Rejuvenation with 1064nm Q-Switched Nd:YAG Laser in Asian Patients, published in Dermatology Surgery 2009; 35: 929-932. You can google the title to get the whole paper.

yes, it does produce the same clinical result with or without the carbon.
i used to do that with carbon but it was creating a lot of problem for my lens on my q-switched laser.

one thing for sure, if you apply thicker coat on the nose area, the carbon peel actually does help on removal some of the white and black heads as well.
Currently, i only use the carbon peel for the nose only.
To my observation, the carbon peel may sometimes cause a little of new acnes on the face. Not all the time, but it happens.

Maybe the smoke evacuator would help with the carbon powder dispersing into the air? Thanks for the great info! What setting should I use for Fitzpatrick IV and above?

10.23 | Unregistered CommenterLC

absolutely NO.
acne scars, if I may suggest, --co2, erbium peel . I have no knowledge on the 1500 erbium glass laser.
I have seen incredible result on acne scars and chicken pox scars using co2 laser.

I usually do subcision prior co2.

10.23 | Unregistered Commenterc.lee

You may use QS ND:YAG for atropic acne scars instead of injecting fillers.

Here is the published article: Treatment of Atropic Facial Acne Scars with the 1064nm Q-Switched Nd:YAG Laser. Arch Dermatol 2004; 140: 1337-1341 (for details, just google the title)

I always use cling wrap to wrap around my IR acupuncture laser lens to keep it clean. I'm thinking if it's possible to wrap up the lens of my QS laser in order to protect it from the damage caused by flying carbon particles.

10.25 | Registered Commentercharlie

Hi, c.lee, just some questions for you:
You mentioned that you use QS Nd:Yag to treat acne. Do you use the laser to treat any types of acne or certain types? How was the result? Do you have to repeat treatment regularly in order to maintain the result? Cheers.
