What used to be considered cosmetic laser procedures has expanded to include hair removal, pigmentation correction, skin resurfacing, acne scar reduction, and vascular lesion management. Demand has increased steadily over the last 10 years to around AUD 1 billion per year for the non-invasive aesthetic industry in Australia. This level of commercial activity brings a lot of marketing. The gap between the clinical evidence and the consumer expectation is where most of the problems in this industry start.
Non-Surgical Does Not Mean Risk-Free
The most pervasive misconception about cosmetic laser procedures is that they are automatically safe because they are non-surgical. Large dermatology studies show adverse event rates as low as 0.11% for thousands of procedures, which sounds very low. But what does that include? Reported adverse events include hyperpigmentation, burns, blistering, scarring, infection, and eye injuries. Australian health authorities have repeatedly cautioned that incorrect device settings, inadequate training, and poor patient assessment greatly increase the risk of adverse outcomes.
Risk also varies significantly based on who is operating the device and what skin type is being treated. That leads to the second misconception: that since all laser clinics use similar-sounding treatments, they all produce similar results. Alexandrite, Nd, and diode laser systems are intended for different clinical applications and skin types. Using an incorrect laser for a darker skin type can result in pigmentation changes and burns that would not occur with the proper device.
One Session Is Not A Treatment Course
The biology does not support this marketing around laser hair removal, as hair grows in multiple phases. Laser energy is most effective only during the active growth phase. Because not all follicles are in that phase simultaneously, multiple sessions spaced several weeks apart are needed to achieve a meaningful reduction across the full follicle population. Clinical protocols always recommend a series of treatments rather than a single procedure. Long-term studies confirm that even after a full course, maintenance sessions may still be necessary.
The mistaken belief that one treatment session is enough is directly linked to the second fallacy that if results are not dramatic, the solution is to crank up the settings. Clinical evidence indicates otherwise. Excessively aggressive treatment parameters can result in more tissue damage with no commensurate improvement in outcomes. In one study evaluating thousands of laser procedures, hyperpigmentation was the most commonly reported adverse event when treatment settings were not appropriate for patient characteristics. In a series of cases reported by Australian dermatologists, burns, pigmentation problems, and scarring were caused by treatments that were too aggressive. These could have been avoided with properly calibrated parameters.
Not All Laser Clinics Operate Under the Same Rules
Although consumers may assume that national regulation ensures a basic level of safety among cosmetic laser providers, the regulatory picture in Australia is more fragmented than this. Training, licensing, and supervision requirements vary from state to state and territory to territory. Some jurisdictions more tightly regulate high-powered laser devices. Others rely more heavily on general consumer protection mechanisms. Medical experts have commented that demand for cosmetic laser services has increased far more rapidly than the regulations intended to regulate it.
In practice, this regulatory inconsistency means that the consumer bears the burden of due diligence. It is not uncommon for the marketing of lasers to avoid or be vague about the answers to questions like: checking the qualifications of the practitioner who will administer the laser; asking which laser system will be used, and why it is a good match for your skin type; asking what the realistic range of outcomes is, versus the best-case scenario; and asking what recourse is available if complications occur. This information is in the clinical literature.
