'Why does laser hair removal require multiple sessions?'

'Why do results differ even when the same procedure is performed?'

If you have considered or already undergone laser hair removal, you have probably wondered about these questions at least once.

Even when people are told that the same device was used, some are highly satisfied, while others may worry that their hair continues to grow even after several sessions.

In fact, hair removal results are not determined simply by the name of the device. Multiple factors work together to create differences in the outcome.

Today, we will take a detailed look at why hair removal procedures need to be repeated and what key factors make a difference in the results.

Why are multiple sessions necessary?

Laser hair removal works by delivering laser energy to the melanin pigment inside the hair follicles that produce hair, generating heat and gradually reducing hair growth.

However, the hair on our bodies does not all exist in the same state. It grows through repeated cycles consisting of the growth phase, regression phase, and resting phase.

Because lasers respond best to hair in the growth phase, it is difficult to treat all hair in a single session.

Therefore, repeated treatments at regular intervals are needed to gradually reduce the amount and thickness of the hair.

In addition, hair thickness and density, as well as follicle depth, vary from person to person, so results may differ even when the same approach is used.

For this reason, it is important to assess the current condition of the skin and the characteristics of the hair, then make appropriate adjustments at each session.

Why spot size matters

Even when the same device and wavelength are used, the efficiency of energy delivery varies depending on the spot size, which is the area exposed to the laser beam.

Using a laser device with a wavelength of 755 nm, the results were examined under the same energy conditions while varying only the spot size between 12 mm and 18 mm.

When followed up for six months after treatment, the area treated with the 18 mm spot showed a relatively more consistent reduction in hair volume than the area treated with the 12 mm spot.

On average, the area treated with the larger spot showed a reduction of more than half of the hair volume, while the area treated with the smaller spot recorded a relatively lower reduction rate.

This difference is known to be significantly affected by energy scattering that occurs at the skin's surface.

The critical difference that determines the results

As the spot size increases, energy scattering at the skin's surface decreases, allowing the energy to penetrate more deeply and intensely to reach hair follicles located deep within the skin.

This does not mean that the absolute intensity of the energy was increased excessively. Rather, it means that the method of delivering the same amount of energy was adjusted.

If the energy does not reach its target properly, hair removal efficiency decreases. Conversely, increasing the intensity to compensate may cause discomfort such as redness or irritation.

Therefore, rather than simply comparing the device name or output, you should check whether the treatment offers detailed settings that can deliver energy efficiently.

To reduce the burden while expecting improved results, each session should also involve uniform irradiation tailored to the individual's skin tone and follicle depth.

Today, I explained the topics that people considering Yangcheon-gu laser hair removal frequently ask about.

Hair removal results are not determined solely by the type of device. Differences may arise depending on how efficiently the energy reaches the hair follicles.

In addition, skin condition, follicle depth, and hair density vary from person to person, so results may differ even when the same approach is used.

Developing a plan that fully considers the characteristics of your skin and hair may help you manage them in a more satisfactory direction.
