How to do laser hair removal at home

Had clinical laser hair removal and see regrowth? How to touch up at home

Banishing those pesky dark hairs from your bikini line forever–sounds too good to be true, right? With summer already here and the leg-baring shorts and bathing suits have been dusted off from storage, we are excited to get out to bask in the sun. But who wants to spend a chunk of their day in the shower shaving away unwanted hair? That is why I think that laser hair removal is a godsend for people like me who used to grow leg hairs overnight after shaving it on a hot summer day.

As wonderful as it all is, there is always a chance you are going to see some hair regrowth. One of the most frequent questions I receive from customers is: I had laser done at a clinic, and now I am seeing regrowth and don’t want to spend the money again to have it treated. Will your 4X Hair Removal Laser work on these stray hairs? The answer: YES! 

Tria 4X Hair Removal LaserThe great news for these types of customers is that our 4X Hair Removal Laser uses the same diode laser technology as the laser that is used in a clinical setting, and is more powerful than an IPL device, so you will see quicker and more effective results with the 4X than any other at-home device.

How does at-home laser hair removal work?

Not only will you save on expensive gas to get to the clinic, there’s no need to sit in a waiting room with your hot face mask on. Here’s how the laser works:

  • Targets: Tria’s Hair Removal Laser 4X  targets the pigment in the hair, without touching the surrounding skin.
  • Treats: Once the device identifies the hair melanin (differentiating it from the melanin in the skin by color), it sends highly-concentrated light through it. The light is converted into heat, which disables the hair follicle.
  • Disables: The hair from the disabled follicle falls out, leaving behind soft, smooth skin.
  • Maintains: Over time, the laser effectively disables the hair follicle’s ability to grow back hair.

You only need to touch up your regrowth areas once every two weeks until the hairs have fallen out. Keep in mind, if these hairs are red, white, grey, or blonde, they will not work with the laser as it cannot find the pigment.

Skincare to avoid when doing laser hair removal

Skincare products to avoid when doing laser hair removal

Summer is just around the corner, and it is the perfect time to start your laser hair removal sessions! As with any laser procedure, whether you are doing it at home or in a clinic, there are some dos and don’ts that you will need to learn about. Today, I’ll discuss the skincare products that should be avoided before, during, and after laser hair removal. These tips will help ensure that you will have a comfortable, safe, and stress-free hair removal experience. Let’s get started!

Avoid exfoliants and peeling skincare products for 5-7 days before and after laser treatment

This no-no is a tough one for me since I love to use scrubs on my legs to get that summer glow. But before doing laser hair removal, it is very important to stop using the following items at least 5 days before your treatment:

  • Alpha Hydroxy or Beta Hydroxy (AHA/BHA)
  • Hydroquinone – this is a topical skin bleaching agent to lighten pigment
  • Retinols and retinoids like Retin-A or Differin
  • Salicylic Acids
  • Sugar/Salt scrubs
  • Benzoyl Peroxide

Since the above list of items is designed for exfoliating your skin and removing dead skin cells, these products can also cause your skin to become extra sensitive. Some of these ingredients can be found in body washes and body creams, so be sure to take a look at the ingredient list on your body products before applying. You should wait at least 5 days after your laser treatment to start using these products again. Laser hair removal causes your pores to open, so let your skin heal and give it a break for a week before going back to any of these skincare products. Read More

Tis’ the season for laser: Your laser hair removal questions answered

As you can imagine, Tria receives a lot of questions about our best-selling product; the 4X Hair Removal Laser. We teamed up with double board-certified Cosmetic Dermatologist, Dr. Karan Lal, to help answer our top five laser hair removal questions that we receive. I’ve included quick links so you can hop to our YouTube video with Dr. Lal to hear him answer the questions himself! Let’s go!

How long does it take to see results with the 4X Laser? Why?

If you are familiar with at-home beauty devices, you may be aware that it does take time and dedication in order to see results. You also have to stay on a treatment schedule (see below: How often should I use the 4X Hair Removal Laser) so that you do not miss an opportunity to disable hair follicles that are in the anagen growth phase.
See us answer the question on YouTube

Hair growth phasesAccording to data collected from our customers and clinical studies, we are seeing that it can take 3 to 6 treatments to start noticing the hair loss. Because your hair follicles have to be in the anagen hair growth phase in order to be effective, it can vary from each person since all of our follicles are in different phases, and each person’s anagen phase can last different lengths of time. It can take 4-6 months’ worth of sessions to see the full results. The thicker and longer hair you have, the longer it can take, according to Dr. Lal. <!–more–>

Does numbing cream or gel work for pain management during laser treatment?

Apply lidocaine cream before doing laser to minimize painSee us answer this question on YouTube.

We get this question a lot. It’s totally understandable as we all tolerate pain in different degrees. Dr. Lal specifies that the hair follicle lies within the fat, so that is why you feel a slight zing when you use the Tria Hair Removal Lasers. He suggests using a lidocaine cream, like LMX 4%, and not a gel or roll-on solution. Dr. Lal also suggests applying a thick dollop and applying saran plastic wrap to help with absorption, wait an hour, wipe away with a cloth, then treat with the laser.



How often should I use the 4X Hair Removal Laser?

Click here to read our blost post that answers this questionTria 4X LED Screen!

Tria suggests using the hair removal devices once every two weeks, without skipping a treatment. I mentioned the anagen hair growth phase above to describe why it takes more than one session to see results. If you use the laser every day, which some customers had reported that they did, you are wasting not only your time, but laser pulses on your device.

It’s best to mark your calendar to make sure you don’t miss your date with the laser!

Can the 4X Hair Removal Laser help women with PCOS hair growth?

See Dr. Lal answer this question on YouTubePCOS Symptoms!

For women with PCOS, it can be very frustrating and embarrassing to go out in public in fear that someone may see the thick and coarse hair that can grow on the face. In a previous blog post, I talked about how the imbalance of sex hormones can cause uncontrollable facial hair growth in women.

Dr. Lal suggests doing electrolysis for permanent hair removal on the face, but explains that it is extremely painful and expensive. If you can afford it and could tolerate it, then go for it! But for those that want to be discreet and have the convenience of controlling hair growth at home, Tria’s hair removal lasers will do the trick. Keep in mind that you will have to treat the facial hair once every two weeks to control the growth, but it will not be permanent for those with PCOS.

Can men use the 4X Hair Removal Laser?

Man with smooth back

Of course! Tria recommends that men use the at-home hair removal lasers from the neck down, since treating facial hair can cause a burn due to the density. Men can safely treat chest hair, arms, under arms, top of hands, back, legs, and feet. We do not recommend that anyone use the laser near the genital area–anywhere outside of the bikini line is okay.


We hope this list helps you decide if Tria is the right product for you to use at home! If you have any questions, please reach out to our amazing customer care team here:

Can you do hair removal laser on freckles?

Can you get laser hair removal over a tattoo, moles or freckles?

That pesky hair that is growing out of your mole–you hate it and want it to die. But, can you get laser hair removal over a tattoo, moles, or over your freckles? The answers are not very complicated, but there are reasons why you have to use caution when performing at-home laser hair removal. Let’s take a look!

How does laser hair removal work?

First, we need to understand how laser hair removal works. In basic terms, the laser beam from a hair removal device targets the pigment in the hair follicle on freshly shaven skin. The only way that the laser can find the pigment is if the skin tone is lighter than the pigment color of the hair. If the skin is darker than the hair’s pigment, or if the hair color has little to no pigment in it, the laser cannot find the hair follicle–resulting in the laser not treating those hairs.

Hairy mole
Don’t do it: Keep your hair removal laser away from moles.

So, because a mole can be dark brown or black, the melanin (the natural skin pigment) competes with the color of the hair, resulting in the laser targeting the skin of the mole and not the hair. If the laser targets the pigment in the mole, it can cause a burn, remove the mole from the skin, and yes, it will probably be painful.

With this in mind, you can imagine that the laser will also target the ink pigment in your tattoos–with possible burns and accidental tattoo removal. You definitely do not want to experience that sensation! <!–more–>

How can you avoid burning moles and tattoos?

White Eyeliner Pencil
Use a white kohl eyeliner pencil to cover moles.

If you are afraid that you will accidentally target a mole or a tattoo, there is a simple solution to keep yourself safe! There are a couple of ways to cover your moles, but you can use a white pencil (like a white kohl eyeliner pencil) to draw on the mole so that the laser does not detect the melanin. You can also use a white circle sticker to place over the mole during treatment, and just treat around the sticker.

For tattoos, it is easy to place white medical tape on the border of your tattoos so that you don’t accidentally target the ink zones.

Are freckles safe to laser?

Yes! You can go over your beautiful sunkissed freckled skin without harm. We suggest taking a good look through your freckle constellation and making sure there are no raised moles or very dark moles that could be present. You can draw over those areas with the white kohl pencil just to be on the safe side. Then you are ready to go blast away those hair follicles!
