Underarms are the area most people start with, and it’s not hard to see why. Shaving every other day, dark shadows in sleeveless tops, ingrowns that come back the same week you get rid of them. It’s the highest-friction maintenance on your body for the smallest patch of skin.

At Laser X in downtown Toronto, underarm sessions take about 5 minutes. Most people see meaningful reduction within the first three or four visits.

Why people treat their underarms

Underarm hair grows fast. Faster than legs, faster than bikini, fast enough that most people shave every day or every other day just to feel presentable. That’s 30 to 40 shaves a month on some of the thinnest, most sensitive skin on your body, and the results show up as razor burn, ingrowns, folliculitis, and the dark shadow that even fresh shaving doesn’t fully hide.

Waxing isn’t much better. The regrowth window is short, the pain is real, and the ingrowns that follow are worse than shaving.

Laser targets the follicle itself. Every session, more of the follicle stops producing hair. After a full treatment course, most people go from daily shaving to a touch-up shave every few weeks, and eventually to not thinking about it at all.

What you can stop doing

• Shaving every day or every other day

• Fighting ingrowns and razor bumps

• Skipping sleeveless tops on days you didn’t have time

• Buying razors and cartridges every few weeks

• Post-shave burning when deodorant hits fresh skin

Recurrent razor bumps and folliculitis

If your underarms flare up every time you shave — angry red bumps, tender spots, ingrown hairs that get infected — you’re not doing it wrong. Shaving traumatizes the hair follicle, and thin underarm skin has a low tolerance for that trauma. Some people can shave every day and be fine. Some people can’t, ever.

Laser breaks that cycle by removing the reason you’re shaving in the first place. As the follicles stop producing hair, the shaving stops, the friction stops, and the bumps stop with them. This is the transformation clients tell us about most often in this area.

What to expect

• Session length: About 5 minutes for both sides

• Sensation: A quick snap. The Zimmer Cryo 6 (our cooling unit) runs cold air over the area continuously, so your skin is already numb from the cold before the pulse lands.

• Spacing: 4 to 6 weeks between sessions

• Sessions typically needed: 8 to 12 for most people

• Downtime: None. Skip deodorant for 48 hours after, plus active exercise, saunas and sun for the same period.
