Most disappointing laser results are not the machine’s fault or the technician’s — they come from preparation. Waxing three weeks before, a holiday tan nobody mentioned, retinol used the night before. Here is the whole thing in order, with the reasoning behind each rule.
Each rule exists for a physical reason, not because clinics enjoy making rules. The reasoning is next to each one — it makes them much easier to remember.
It sounds contradictory. You are paying to remove hair, and you are told to remove it yourself first. But the two methods do opposite things to the follicle.
Shaving cuts the hair at the surface and leaves the root, shaft and all of its pigment sitting in the follicle below. That pigment is the target. The laser passes through the surface of your skin, the melanin in the hair absorbs the energy, and the heat travels down to destroy the follicle that produces it.
Waxing, threading, plucking and epilating pull the entire hair out. The follicle is still alive, but it is now empty — there is no pigment for the laser to find and nothing to conduct heat down to the root. The session happens, you pay for it, and almost nothing is achieved.
Four weeks is the minimum because that is roughly how long it takes for enough follicles to re-enter their growth phase with a hair actually in them. If you have waxed more recently than that, moving the appointment is not being difficult — it is the only way the session is worth having.
Yes, as often as you like — shaving has no effect on your results at all. What you must not do between sessions is wax, pluck, thread or epilate, because those remove the follicle the laser needs to find at your next appointment.
Tell your technician and reschedule. Treating an area that has been waxed recently means paying for a session that cannot work, because the follicles are empty. Four weeks of growth from the root is the minimum.
Finish your session at least two weeks before you travel, and plan not to treat again until two weeks after you are back and any tan has faded. Sun exposure on either side of a session is the main risk factor.
Yes. Any surface hair absorbs laser energy above the skin instead of below it, which means less energy reaching the follicle and a higher chance of surface irritation or a singed smell.
Yes, though the bikini area can feel more sensitive at that point in your cycle. Many clients prefer to move the appointment — just let Sukh know and it is rescheduled at no cost.
Mild pinkness for a few hours is normal and it usually settles overnight. If it is still pink after twenty-four hours, or you see blistering or unusual darkening, call straight away. That is not something to wait out.
Twenty minutes, a patch test, and a written plan with your own preparation dates on it. No charge and no obligation.
