VIO脱毛の痛みは鋭さがないと気づいた

Kevin's Report After Completing Full-Body Hair Removal (ゼンシン脱毛)

Kevin has wrapped up his full-body hair removal course, and this episode is his field report. The focus isn't on finishing itself but on a specific observation: the *quality* of pain varies dramatically from one body part to the next, and the VIO area in particular surprised him.

The other speaker hasn't had full-body hair removal and joined the conversation as an outside listener — his position throughout was "I can imagine it, but I have no real frame of reference."

The Shin: The Most Unbearable Instant Pain

The hardest part to endure, Kevin says, was the shin. The moment the laser fires, a sharp pain arrives with zero delay. He described it as so immediate that "if it had been any stronger, my body would have flinched on its own" — a reflexive, involuntary reaction rather than something he could consciously control. That direct, linear sequence — shot fires, pain hits — is the defining feature of the shin experience.

The Scrotum: A "Delayed, Rounded Pain"

The most surprising discovery was how different the scrotal area felt. Right after the shot, Kevin felt almost nothing. Then, 1–2 seconds later, a heavy, dull ache arrived. He described the sensation as having "no sharp corners" — "only rounded edges." It doesn't pierce; it spreads. And because there are a few seconds of warning, he said he could mentally brace for it each time. He acknowledged that the total intensity might actually be greater than the shin, but the roundedness of the pain made it strangely manageable.

The Hypothesis: Bone Presence Determines Pain Sharpness

Kevin's explanation for the delay: no bone. Areas like the shin or the bony parts of the face — cheekbones, the jawline — have hard structures just beneath the surface. When the laser's heat and impact hit that hard wall, they bounce straight back, producing a sharp, instant sting. The scrotum, made entirely of soft tissue with no bone underneath, absorbs the impact differently — the force gets softened and deflected rather than reflected, so the pain arrives late and feels blunt.

The other speaker backed this up, noting he had heard that bony areas of the face are especially painful during hair removal, which fit exactly the same logic Kevin was describing.

Testing the Hypothesis with an Extreme Example: "If You Were Stabbed"

Kevin pushed the idea further into the absurd: if someone were going to stab you, the scrotum might actually hurt less than the abs or the chest, where bone sits close to the surface. The pain would still arrive — just slowly, and rounded. He framed this as a theory drawn purely from personal experience, not a medical claim.

The other speaker said that before hearing Kevin's account he had always assumed that area would be extremely sensitive and therefore extremely painful — the opposite of what Kevin found. He enjoyed the contrast between his prior assumption and Kevin's lived reality.

The Other Speaker's Interest in Full-Body Hair Removal Is Zero

The two had already talked about full-body hair removal a few weeks earlier. Kevin returned this episode with what he had discovered since then. The other speaker's response was immediate: zero interest in trying it himself. "Hearing your stories is interesting enough — that's plenty," he said, making clear he had no intention of going through the process. Kevin closed by saying he would keep sharing this journey as it continued.
