Laser hair removal aftercare

The first day is about heat and friction, the first week is about sun and picking, and the third week is about shedding. Knowing which week you are in stops most of the panic.

The first evening

Redness and small bumps around each follicle are the normal response, and they usually settle within a few hours to a day. The skin may feel warm and slightly swollen, particularly on the bikini line, the underarms and the face. Cool the area with a cold pack wrapped in a cloth if it is uncomfortable, keep the skin clean, and wear something loose over it.

Skip the hot shower, the sauna, the steam room and the gym for the rest of the day. Heat and sweat increase blood flow to skin that is already reacting, and friction from clothing or equipment is the usual reason a treated area becomes irritated. A lukewarm shower is fine, and patting the skin dry rather than rubbing it is kinder. If you have a long drive home, keep the treated area covered with loose fabric rather than with a waistband or a seatbelt edge pressing against it.

The first week

Keep the area out of direct sun and use a high factor sunscreen on any skin that will be exposed. Pigment change after treatment is a common avoidable complication, and sun is the usual cause. Do not scrub, do not use acid exfoliants, and do not apply a retinoid to the treated area until the clinic says the skin has settled.

Do not pick at the skin, and do not shave over an area that is still tender. If the skin blisters, breaks, or develops a crust, contact the clinic the same day and ask what they want you to do. Blistering is not a normal part of a good session, and it is a reason to review the settings before the next one rather than push through.

Shedding, and the false alarm

Treated hair does not fall out immediately. The follicle releases the shaft over the following one to three weeks, and during that window the hair looks like it is still growing, because the dead shaft is being pushed out. This is when people decide the treatment failed, usually about a week before the result appears.

Gentle exfoliation in the shower after the first week helps the shed hair leave the surface, as does a soft cloth. Do not pull at hairs that seem loose, and do not wax or epilate to clear them, because that resets the area for the next session and removes the shaft the laser would have used.

What to raise with a clinician

A treated area that becomes increasingly red or warm, swells, weeps, or is painful beyond the first day is not routine, and it should be assessed rather than managed at home. The same applies to a fever, spreading redness, or a spot that forms pus. Contact the clinic, and if they are unavailable, speak to a clinician.

Changes in skin colour, whether darker patches or lighter ones, are also worth raising with the clinic and with a clinician, particularly on darker skin tones. Many settle over months, and a clinician can tell you whether what you are seeing needs review or simply time.

Between sessions

Shaving is fine between sessions once the skin has settled, and it is what you should use instead of wax, sugar, threading or an epilator. Sun protection stays relevant for the whole course, not just the week after a session. So does telling the clinic about anything new: a holiday, a new medication, a course of antibiotics, a change in your cycle.

Book the next session at the interval the clinic recommends, usually four to six weeks, and move it if your skin has not settled. Turning up with skin that is still reacting is how settings get lowered and sessions get wasted. Turning up with a fresh tan does the same thing, with less excuse, which is why the sunscreen between sessions is part of the treatment rather than an optional extra.

Where this sits in the rest of the site

If you are choosing a clinic rather than reading up, start with how the treatment works and what drives the price, then compare the markets we cover and what we verify before you book anything.
