Key takeaways
- There is no universal session count: the schedule depends on the area, hair, skin type, and observed response.
- The face, underarms, bikini area, legs, and back do not all follow the same regrowth pattern.
- Lutronic Clarity II combines 755 nm Alexandrite and 1064 nm Nd:YAG to adapt treatment to the assessed skin and hair profile.
- The realistic goal is long-term hair reduction; maintenance may be recommended depending on regrowth.
- At Institut V Esthétique, the consultation determines the appropriate wavelength, treatment area, and timing.
How many sessions should you plan by area, skin tone, and hair type?
The number of sessions can only be estimated by considering the treated area, hair density and pigmentation, skin type, and individual response together. The American Academy of Dermatology also notes that the treated area, laser type, skin colour, and the colour and thickness of the hair all affect results.
Laser primarily targets pigment in hairs that are in an active growth phase. Because not every hair in an area is active at the same time, a series of appointments is required. The schedule should not simply be copied from one person or one body area to another.
| Area | Attribute to assess | Practical effect on the protocol |
|---|---|---|
| Face and chin | Regrowth may be influenced by hormonal factors | Careful assessment and possible maintenance as regrowth evolves |
| Underarms and bikini | Hair is often denser and more pigmented | Settings selected for skin-hair contrast and area sensitivity |
| Legs and arms | Larger surface with variable density | Appointment length and coverage adapted to the actual area |
| Back and chest | Distribution and thickness vary by person | Personalized plan rather than a universal session count |
This is why a “full body” package does not mean that every area will progress at exactly the same rate. The full body laser hair removal guide provides the overall view; this article explains the mechanism that makes area-by-area personalization necessary.
How does Institut V build your laser hair removal schedule?
The schedule is established during the consultation, then adjusted according to regrowth, skin response, and observed progress rather than followed as a rigid package. Institut V assesses the skin, hair, body area, and sun-exposure habits before selecting suitable settings and timing.

The Clarity II used at Institut V combines two complementary wavelengths. The 755 nm Alexandrite may be selected for certain skin and hair profiles, while the 1064 nm Nd:YAG is notably used for darker skin types. The choice is never based on the name of the body area alone.
| Entity | Attribute | Practical value |
|---|---|---|
| Alexandrite | Wavelength | 755 nm |
| Nd:YAG | Wavelength | 1064 nm |
| Clarity II | Function | Allows wavelength and settings to be adapted to the assessed profile |
| Consultation | Purpose | Assess skin, hair, area, contraindications, and expectations |
Before an appointment, follow the instructions given for the treated area and avoid removing the hair by waxing or tweezing. The guide How to prepare for your first laser hair removal session explains the useful steps. For darker skin types, also see the guide to laser hair removal for dark skin.

Frequently asked questions
Does the same number of sessions suit every body area?
No. The area, hair density, colour and thickness, skin type, and individual response influence the plan. Institut V adjusts timing after the assessment and according to observed progress.
Why might an area require maintenance?
Some regrowth can appear over time. It is often less noticeable, but individual or hormonal factors may make maintenance sessions appropriate.
Can Clarity II be used on darker skin?
Clarity II includes a 1064 nm Nd:YAG wavelength used for darker skin types. A consultation is still required to assess the skin, hair, area, and suitable settings.
