Expect Minor Side Effects

Women Getting Laser Hair Removal

Laser hair removal treatments consist of a series of high intensity light impulses. During treatment, you may feel a tingling or prickling sensation due to light acting on the hair follicle beneath the skins surface. Your skin also reacts adding to the tingling feeling.

For most people, irritation should disappear within hours . You should have no lingering discomfort with laser hair removal.

“Minor side effects are expected for most users. If irritation lasts longer than a few hours or seems unusual or painful, contact your physician”


Laser hair removers can cause temporary redness and/or swelling at the area after treatment. Any redness or swelling will disappear within hours of your treatment. Side effects will vary from person to person. Remember, your skin will be sensitive to direct sunlight after your laser treatment so be sure to use a high SPF sunscreen and of course avoid tanning booths.

Pigment Changes after laser hair removal

Skin Discoloration -HypopigmentationAfter a laser treatment, you may see areas of your skin have become lighter or darker in color.

Just like redness, pigment changes are only temporary so don’t be concerned if this happens to you. Reminder – Always treat a small area before your first use of a home laser hair remover. Treat the area and wait a day to see if your skin reacts in an adverse way to the laser.

How Much Do Laser Hair Removers Cost?

The cost of laser hair removal is the first and most important consideration when deciding which laser hair remover is right for you. You will be considering initial cost, maintenance (lamp replacement etc.), treatment times and whether you want a cordless device.

Initial cost of your laser will vary between brands. You can get an inexpensive unit starting at under $200 while the more professional style units will run up to $1000. There is also a big price difference between a diode style laser and an IPL device with lasers coming in at the high end of the price range. More about IPL vs Laser.

Clean Shaven UnderarmConsider maintenance costs while shopping for your laser. Some lasers have replaceable lamps/lasers while others do not. Whether it is a laser or replaceable lamp, the most important consideration is expected lifespan of the laser or lamp. Usually measured in “Flashes”, you will get an idea of how long the unit/lamp will last by how many flashes can be expected. Also keep in mind that a laser will have a smaller treatment area thus will require more flashes per treatment. See treatment times below.

Treatment times are directly proportional to the size of the laser or lamp. Larger treatment areas allow faster treatments.

Some models are rechargeable and others require an AC outlet. Designed to be comfortable and easy to hold, applying a treatment is fast and virtually effortless. The average time for a laser application to both legs is between 15 to 30 minutes. Just like at your physicians office, the laser treatment is re-applied after 2-3 weeks and 4-6 applications are required for permanent hair removal. Most units are adjustable for your specific skin and hair type.

The cost differences between brands is due to the type of attachments included in the kit. Some kits come with extra lotions and creams for application after the laser treatment. Usually, none of these extra’s are required and any over the counter skin lotion or cream will suit your needs.

Hair removers – Laser vs IPL

Laser Hair Remover VS IPL

Laser and IPL hair removers both use light energy to heat melanin (pigment) in the hair follicle. This heat damages the hair follicle preventing it from producing new hair.

Lasers use a diode laser to produce light and IPL uses a high intensity lamp. Both emit a short burst of light energy and work exactly the same. Some things to keep in mind are that a laser will produce permanent hair loss with fewer treatments than an IPL device but generally cost much more than an IPL hair remover.

How Do Laser Hair Removers Work?

High intensity light heats the pigment in the hair follicle causing damage that kills the follicle preventing further hair growth. This is why if you have dark skin and light hair, the light may not penetrate the skin enough to act on the follicle. This is also true is you have very light hair and there is not enough pigment in the root for the light to act on. See Laser vs IPL Above.

REMEMBER: Lasers and IPL devices target the pigment in the hair follicle. If you have very dark skin, your options are limited to a device that can penetrate dark skin such as the Tria 4X Laser
