Underarm Laser Hair Removal: Sessions, Comfort and Aftercare — Istanbul
Underarm laser hair removal is quick: both underarms take about 10 minutes. A small area does not mean fewer sessions, though — a course is still typically 6–8 sessions, 6–8 weeks apart, because laser only reaches hairs in their active growth phase. The aim is permanent hair reduction: fewer regrowing hairs, finer and lighter ones where some remain, and less shaving. This guide covers how it feels, who it suits and how to prepare for treatment at our clinic in Nişantaşı.

Permanent hair reduction
Small area, same number of sessions
The number of sessions depends on the hair growth cycle, not on the size of the area. Only hairs in the active growth phase (anagen) absorb enough light for the follicle to be damaged, and at each session only part of your underarm hair is in that phase.
What a small area does change is the time: about 10 minutes, easy to combine with legs or bikini in one appointment.
How underarm laser hair removal works
Underarm hair is usually dark and coarse, the kind of hair laser targets: melanin in the hair absorbs the light, and the heat damages the follicle.
The skin here is thin and folded, so the laser is chosen with care: Alma Soprano Ice (diode 810 nm, in-motion technique with cooling) suits most skin types, alexandrite 755 nm suits light to olive skin, and Nd:YAG 1064 nm is the safest choice for darker skin. See our laser technologies page.
Underarm laser hair removal sessions and intervals
- Session 1About 10 minutes for both sides; redness and small bumps last up to a day.
- 1–3 weeks laterTreated hairs shed and may look like new growth. Shave if needed; do not pluck.
- Every 6–8 weeksThe next session treats hairs that have since entered the growth phase.
- Sessions 6–8A course typically ends here, with fewer, finer and lighter hairs.
- LaterOccasional maintenance, for example once or twice a year, if some hairs return.
Does underarm laser hair removal hurt?
Expect warmth with light prickling for a few minutes. Because the skin is thin, the heat can feel more noticeable here than on the legs.
Alma Soprano Ice glides over the skin in repeated passes while cooling it, which keeps the session comfortable. Tell us how it feels at any point; the settings can be adjusted.
Is underarm laser suitable for my skin and hair?
The laser is matched to your skin type (Fitzpatrick I–VI) and your hair:
- Dark hair: the main target of laser, on light, olive or darker skin.
- Darker skin: Nd:YAG 1064 nm is the safest choice; Soprano Ice suits most skin types.
- White, grey, red or very light blonde hair: little or no effect.
- Hormonal hair, for example with PCOS: may need more sessions and maintenance.
- Recent tan or sunburn: the session is postponed.
Before and after your underarm session
More detail in our laser before and after care guide.
- About 4 weeks before: no waxing, plucking, epilating or threading; shaving is fine.
- 2–4 weeks before: no sun tanning, self-tan or bleaching.
- 12–24 hours before: shave both underarms.
- Tell us about: photosensitising medicines, recent isotretinoin, pregnancy or tattoos.
- 24–48 hours after: no hot showers, sauna or intense sport; use the soothing gel.
- After that: SPF 50 for about 2 weeks if the area is in the sun; shave only between sessions.
Underarm sweating is a different treatment
Laser hair removal is designed to reduce hair, not sweating. For heavy sweating we use Botox for excessive sweating, which in the underarms typically lasts about 4–9 months.
You can have both: after underarm Botox, wait about 1 week before laser on the same area.
Side effects and when to postpone
Redness and mild swelling are common and short-lived. Rare: blistering, burns and temporary pigment changes. Very rare: paradoxical hair growth.
We postpone treatment in pregnancy, with sunburn or a recent tan, an active infection or rash in the area, photosensitising medication or recent isotretinoin; a keloid tendency or light-triggered epilepsy needs extra caution. If a blister appears, contact us straight away.
