Medical grade laser hair removal uses clinical technology for permanent results, not a lower-powered salon device. This guide covers what that distinction means in practice, how we build a treatment plan around your skin and hair, and why it holds its value against years of waxing or shaving.
What medical grade actually means
A medical grade laser is a Class IV device, regulated for its safety and effectiveness. It delivers enough energy to disable the hair follicle permanently while protecting the surrounding skin, which is a higher standard than the lower-powered equipment used in most high-street salons.
Medical grade versus IPL
IPL (Intense Pulsed Light) uses a broad, scattered spectrum of light. Because it is less targeted, it often only stuns the follicle instead of destroying it, which is why regrowth can appear within a few months. A true laser uses a single, concentrated wavelength that reaches the base of the follicle, which is what makes the result permanent, not temporary.
Safety comes first
Operating a Class IV laser requires training in skin biology, not just the device itself. We follow strict protocols to prevent hyperpigmentation or burns, and the system's cooling technology protects the skin surface throughout the session.
Building a treatment plan for your skin
Your plan starts with a consultation that assesses your Fitzpatrick skin type and hair density. Richer skin tones need more careful calibration of the laser's fluence and pulse duration to reach full follicle destruction without any risk of burns or irritation. Because hair grows in cycles, the laser can only affect follicles in their active growth phase, so a course of 6 to 8 sessions is standard. Clients typically notice less pigmentation from ingrown hairs and visibly thinner, slower regrowth within the first few sessions.
Treating it as a long-term investment
Over five years, a full course of bikini laser hair removal, including maintenance, typically costs between £600 and £1,200. Professional waxing over the same period, for the same area, typically costs between £1,500 and £2,400. A full course of laser gives a 70 to 90 per cent permanent reduction in hair growth, so both the ongoing cost and the time spent on grooming fall once the course is complete.
Preparing for and recovering from a session
- Shave the treatment area around 24 hours before your appointment.
- Avoid waxing, plucking or hair removal creams for at least four weeks before your first session.
- Keep the skin free of lotions, oils and deodorant on the day.
- Avoid heat, intense exercise and saunas for 48 hours afterward.
Frequently asked questions
Is medical grade laser hair removal permanent?
Yes. A full course gives a 70 to 90 per cent reduction in hair growth by disabling follicles during their active phase. Occasional maintenance visits may still be needed if dormant follicles become active later due to natural hormonal changes.
Does it hurt?
The integrated cooling system keeps the experience comfortable. Most clients describe a gradual warming sensation, not the sharp sting associated with older systems.
How many sessions will I need?
Most clients need 6 to 8 sessions. This is because hair grows in different cycles, and the laser can only treat a follicle while it is in its active growth phase, so multiple appointments are needed to catch every hair.
Can I have it on dark or tanned skin safely?
Yes. The system uses a specific wavelength that bypasses melanin in the skin to target the hair follicle directly, which keeps the treatment safe across all Fitzpatrick skin types.
Is it safe during pregnancy or while breastfeeding?
We do not treat clients who are pregnant, as a precaution, and hormonal changes can also make the treatment less effective. If you are breastfeeding, speak to your GP before booking a course.
