What I learned from a laser hair removal consultation in Gangnam

When seeing patients near Gangnam's Sinnonhyeon Station, we often meet those considering laser hair removal due to post-shaving irritation, folliculitis, or stubble reappearing within days. To put it simply, laser hair removal is not a one-time procedure; it's most effective when performed in multiple sessions, timed with the hair growth cycle. Today, rather than promotion, we'll focus on what we most frequently explain in the consultation room.

Why is repeated laser hair removal necessary?

Laser hair removal is not about plucking or shaving hair. It's known to work by using energy that reacts to melanin pigment in the hair follicles, gradually weakening the hair's growth ability. The issue is that not all hairs on our body grow simultaneously in the same phase. They are a mix of anagen (growth), catagen (transitional), and telogen (resting) phases, making it difficult for a single session to affect all hair follicles.

Many people feel that hair grew back after just one session, but this is often not because the treatment was ineffective, but because hairs that were in the resting phase at the time emerged later.

Therefore, understanding from the outset that repeated sessions are inherently necessary can make the process much more comfortable. Laser hair removal is a procedure approached with a plan tailored to these cycles.

Which areas are most frequently inquired about?

In the consultation room, we observe that concerns vary slightly depending on the area. Frequently inquired areas include:

• Underarms
• Arms and legs
• Bikini line and Brazilian
• Upper lip, chin, and facial peach fuzz
• Abdomen and back
• Men's beard area

Since hair thickness, follicle depth, and skin sensitivity differ for each area, it's difficult to apply the same laser settings uniformly. Even for the same person, underarms and facial peach fuzz require different approaches. Checking the condition of each area first and then adjusting the settings accordingly is precisely why professional hair removal at a clinic is beneficial.

For women, many also consider hygiene management along with bikini line or Y-zone daily care.

How much pain will be felt?

To be frank, it's not a completely pain-free procedure. Many describe the sensation as a light snap from a rubber band, and it can be felt more intensely in areas with thinner or more sensitive skin. However, recent equipment often includes cooling functions, leading to many reports of reduced discomfort compared to older methods. If you are sensitive to pain, please inform us during your consultation so we can adjust the intensity accordingly.

How many sessions are typically needed?

While there's significant individual variation, the general guidelines we provide in the consultation room are as follows. Please also remember that maintaining the recommended intervals is more important than the exact number of sessions.

The numbers above are average guidelines only and can vary depending on hair thickness and density, skin condition, hormonal influences, and more. Rather than strictly adhering to the figures in the table, it's more helpful to follow the recommended intervals and monitor your progress together with your practitioner.

Can it be done on darker skin tones?

Modern lasers have improved melanin selectivity, making it possible for individuals with darker skin tones to undergo treatment under certain conditions. However, if the laser type selection, pre-treatment skin condition check, or energy settings are incorrect, it can lead to irritation or pigment changes. Therefore, for those with darker skin tones, we do not recommend proceeding uniformly without prior assessment.

Why are differences in equipment important?

It's difficult to assume that all laser hair removal devices are similar just because they're lasers. Commonly used devices include Alexandrite, Diode, and Nd:YAG, each with different ranges of skin tones and hair thicknesses they effectively treat. The results and perceived discomfort can vary depending on which device is used and with what settings. Therefore, it's better to confirm if the approach is suitable for your skin and hair condition, rather than choosing based solely on price.

At Blanc OB/GYN, we first assess your skin tone, hair condition, and whether the area is sensitive using our available equipment, then adjust the settings within a safe range. This is why some patients who have undergone treatment after consultation say it was more comfortable than expected. We also inform you that effectiveness and sensation can vary individually.

What should be observed after the procedure?

Skin recovery is important after laser hair removal. Adhering to the following in your daily routine can be helpful:

• Avoid saunas and strenuous exercise on the day of the procedure.
• Moisturize sufficiently.
• Pay attention to UV protection.
• Discontinue scrubbing and waxing for a while.
• Shave only up until the day before the procedure.

Redness usually subsides naturally within a day or two, but if irritation persists or unusual reactions occur, we recommend consulting a doctor without delay.

In conclusion

While many have concerns before starting laser hair removal, it's a procedure that many find satisfying once they commit to a planned course of treatment. If you're considering laser hair removal near Gangnam's Sinnonhyeon Station, we recommend looking beyond just the price and instead focusing on the equipment, settings, and consultation process. Most importantly, it's crucial to thoroughly confirm that the plan is suitable for your skin and hair condition.
