Is Laser and Intense Pulse Light Therapy suitable for Asian skin?

A fellow colleague of mine who practices cosmetic medicine referred a salesman to me yesterday. Since i was quite occupied yesterday, hence I postponed our meeting to today. He called me up first thing in the morning asking for the whereabouts of my clinic. Upon reaching my clinic, he waited for a mere 10 minutes before calling him in as I was seeing a patient.
The first sentence that he uttered immediately gave me the impression that I am in for a long boring, much obligated,meaningless head nodding, and draggy conversation in effort to get a sale out from me. I was right. Throughout the entire conversation, it was more of a monologue rather than a dialogue. He was yacking non stop about how essential laser and IPL machines are in any cosmetic centers, on how I shouldn't contemplate but to invest on the equipments, and that how I would regret later on for not deciding to purchase on it.
He emphasized on his China made products, how it's in par with the ones from US or Germany quality wise but such marked difference in its pricing.

He started bragging about his credentials, that he has been in sales of medical equipment business for the past 25 years. How beneficial it is to do business with cosmetic doctors, guaranteeing the return of investment would be at least 6-7 folds, and all these while repeatedly telling me how I would regret not purchasing the machine later on in life.
After 1/2 hours of non stop bragging on how such investment benefits cosmetic doctors, and repeatedly telling me how I shouldn't be called a cosmetic physician if i don't own any machine, I simply replied, "Isn't laser and IPL don't suite Asian skin?"
Upon hearing my remark, he snapped back telling me that I was wrong to come out with such assumption. He started listing the names of doctors who bought the machines and how their business flourish over the period with the help of these machines.

He started showing me brochures of his products. 

Trying to impress me on the diversity of probes for 1 single machine. 

Personally I felt he tried too hard to convince me to sign up a lease for the machine. So much so that his hidden intention of getting a commission out from the signed deal is written all over his forehead. So far I was approached by two sales representative from two giant cosmetic giant companies that distributes US made machines, who sensed that  I knew about laser more than what they initially expected. What he told me throughout the whole conversations were more testimonials rather than facts. 

These previous two representatives knew THE FACT that laser and IPL don't suite ASIAN skin as we contain more melanin than our western counterpart, hence we burn easily when exposed to laser or IPL. THEY admitted that doctors reduced the intensity of the laser to prevent burn, hence that means the patient would need to come back for several separate sessions, which means they would need to pay more. 

I simply felt the urge to test his knowledge on laser. What he was selling was CO2 laser. I simply asked him, can tattoo be removed by CO2 laser."Of course! CO2 burns the layers of the skin where the tattoo pigments are embedded, hence removing the pigments!" he remarked with a look on his face trying to project the impression that what he just said was a matter of fact! I smiled. I knew then that he DOESN"T KNOW NUTS about lasers! 

I did not spend my time in Australia only purely for my cosmetic training, but attended a course on laser safety and sat for an exam to be board certified laser safety officer, registered in the state of Queensland, Australia. Only registered LSO(laser safety officer) are eligible to purchase and operate a laser machine. Australia being far more advanced in the field of cosmetic medicine than Malaysia. Today, Singapore Ministry of Health have already enforced similar protocol as Australia, requiring cosmetic doctors to attend a course and sit for an exam to be deemed qualified to operate a laser machine. 

Obviously this guy doesn't know that the wall which the room where the laser machine is must be insulated, and the door knob mustn't be metallic in nature, preferably wooden.  It's just a matter of time before our government enforce this rule. Then what are these doctors who had already invested millions on machines going to do?

A proper laser machine distributor is able to recognize the cert that I hung on the wall of my consultation room. It is clearly written the state of which I am registered along with the registration number. 

I have enough knowledge to know that humans are classified by Fitzpatrick's classification based upon our skin colour that we are classified into 6 separate groups, each been assigned by Roman numeric, I,II,III,IV,V,VI. Class III is separated into 2 other subgroups, IIIa and IIIB. The fairest among the Chinese are classified under IIIB, and it is from this group onwards that IPL and laser are not suited as melanin contents increase, the chance of burn increases. Hence, WE AREN'T SUITABLE FOR LASER OR IPL. 

Back to the question on tattoo removal, CO2 laser ARE NOT USED, but instead, the choice depends on the colour of the tattoo. Hence, Ruby laser, Alexandrite laser, and Nd:YAG laser are used in removal of tattoo,NOT BY BURNING AWAY  the layer of skin as this joker mentioned, but rather, by dissolving the colour pigments and then removed by our body's immune system. 

Hence, this is my rationale why laser and IPL are not best suited for ASIAN skin. For the salesman who came this morning who tried hard to intimidate me by indirectly labeling me as not "suited to be called Cosmetic physician", he should have his facts right before approaching anyone to make a sale. Just because a practitioner doesn't own a laser machine, doesn't mean he don't know nuts about lasers, but maybe...just maybe perhaps the doctor have enough sense not to invest on equipment that does more harm than good.
