Key takeaways
- The course structure is the same everywhere: 6–8 sessions, 4–6 weeks apart. The appointment length is not.
- Coarse, dense areas like the underarms respond fastest; fine arm hair is the slowest.
- Bone-close areas register more sharply, and they are also the quickest to pass.
- Sun exposure is the practical constraint on legs and forearms, not pain or cost.
Same course, very different appointments
Every area follows the same rhythm — a course of 6–8 sessions, 4–6 weeks apart, because the laser only disables follicles that are in their active growth phase. What changes between areas is how long you are on the bed, how it feels, and how quickly you notice a difference.
| Area | Appointment | Feels like | Responds |
|---|---|---|---|
| Underarms | Among the shortest | Sharp but over in minutes | Fast — coarse, dark, dense |
| Legs | Longest single area | Easy on calves, sharper on shins and knees | Steady; sun is the constraint |
| Arms & hands | Short to moderate | Sharper at wrist, elbow, knuckles | Slower if the hair is fine |
| Back & shoulders | Long | Sharper over the shoulder blades and spine | Fast on shoulders, slower low down |
| Chest & stomach | Moderate | Sharp on sternum and ribs, easy on the stomach | Good on coarse hair |
| Full body | Longest visit we run | Varies by area | Areas finish at different times |
What makes one area quicker than another
- Pigment. The laser targets the pigment in the hair, so dark coarse hair absorbs more energy and responds faster than fine, light hair.
- Density. Dense areas look dramatically different early simply because there is more to remove.
- Surface area. Legs and backs take longer per visit, not more visits.
- Hair cycle. Face and neck hair cycles faster than body hair, which is why facial sessions are spaced more closely.
The rules that apply everywhere
- Shave 24 hours before. Never wax, epilate, thread or tweeze during a course — the laser needs the root in place.
- Two clear weeks with no sun, tanning bed or self-tanner before and after every session.
- Skip the gym, sauna, hot tub and pool on treatment day. Sweat and friction cause most avoidable irritation.
- Expect shedding, not regrowth. Treated hairs work their way out over a week or two afterwards.
- Keep to your spacing. A late session simply misses the growth phase it was timed for.
The two things that actually derail a course are a holiday tan and a missed shave — not pain, and not the technology.
Honest limits, whichever area
Laser needs pigment in the hair. Brown and black hair on any skin tone responds well; white, grey and very fine blonde hair does not, because there is nothing for the laser to act on. On deeper skin tones we use the Nd:YAG wavelength on the Candela GentleMax Pro, which passes through the skin’s pigment and targets the hair instead. We look at your actual hair at a free consultation and tell you what to expect before you commit to anything.
Your questions, answered
Straight answers from the Oxyderm clinical team on the questions this article raises. Browse all 88 answers or ask us directly.
Which area gives the fastest results?
Areas with coarse, dark, dense hair — underarms and the bikini line typically — show a visible difference earliest, because there is a lot of well-pigmented hair for the laser to target. Fine arm hair is usually the slowest.
Does the number of sessions change by area?
The course structure is the same — usually 6–8 sessions, 4–6 weeks apart. What varies is how much progress you see per session, and areas with finer hair can need more patience. We review each area as the course goes.
Which areas hurt most?
Anywhere the skin sits close to bone: the shins and knees, the wrist and elbow, the sternum and ribs, the hip bones and the shoulder blades. Those areas are also small, so the sharper part of the appointment is brief.
Can I treat several areas in one appointment?
Yes, and most clients do. If you are treating three or more it is usually simpler to put them on one coordinated schedule — see our guide to full body laser hair removal.
How long is a session?
Underarms are among the shortest on the menu; full legs or a full back are at the long end; a full-body visit is the longest we run. Your technician confirms the time for your exact booking at the consultation.
Is the price the same for every area?
No — pricing is per area and reflects the size and time involved. Your technician quotes your specific combination at the free consultation, so you can compare options before committing.
