Charlotte Gomez / BuzzFeed A magical device that permanently eliminates unwanted hair? UM, YES PLEASE. Tap to play or pause GIF Tap to play or pause GIF Universal Pictures Look, we ALL can be lazy. You don't want to wake up earlier than you have to just to shave because it's been a few days and your legs look like the Amazon during rainy season. And waxing is never a good time when growing out your hair beforehand results in you lookin' like Snuffaluffagus. Shaving is more of an annoyance than anything. That uncomfortable prickle when you haven't shaved and are wearing jeans? That 5 o'clock shadow under your arms? Don't lie, YOU KNOW THOSE FEELS.If you're looking for a more permanent solution for your unwanted hair woes, laser hair removal could be the best service for you. BuzzFeed talked to a board-certified dermatologist in order to give you details about laser hair removal treatments. 1. Laser hair removal does not actually work by using magic. View this photo on Instagram This treatment uses a cosmetic laser that has settings adjusted to both your skin and hair type. The laser fires a concentrated beam of light that's directed at the pigment in your hair follicles. This kills the follicle at its root, preventing those suckers from growing back. 2. Stay out of the sun before your appointment. Tap to play or pause GIF Tap to play or pause GIF Warner Bros. At *least* four weeks before, to be exact. You can't receive this treatment if you're sunburned — or even if you have a tan. Summer might not be the best time to start laser hair removal if you're a fan of the outdoors. A lot of people start treatments in the fall or winter in order to have stubble-free skin by summer! 3. You must shave the area you’re getting lasered. Tap to play or pause GIF Tap to play or pause GIF Nickelodeon Do NOT proceed to come in with your hairy self. This isn't like waxing, and you don't need to grow your unwanted hair out beforehand. On that note, you can't come in for laser hair removal if you've had a wax recently. Remember: The laser targets the PIGMENT of your hair follicle, and the follicle actually has to be there in order for this to work.The best thing you can do is shave a day before your appointment. If you don't, your physician will most likely provide you with a razor so you can get 'er done! 4. This also includes staying away from tanning beds, spray tans, and tanning lotion.

If you're for reals about this, queue up some Netflix shows and embrace the indoors for a while! 5. Your physician will provide a test patch on your skin at your first appointment. View this photo on Instagram instagram.com The sad truth is that not everyone's skin will react well to cosmetic laser treatments. Pigment problems, discoloration, and scarring can occur with some skin types, which is why it's important to allow your physician to conduct a small test patch first. 6. Laser hair removal doesn’t automatically make you silky smooth after your first treatment. Tap to play or pause GIF Tap to play or pause GIF Disney I, too, was hoping that the process was a BAM one-and-done kinda deal, but alas it is not. Dr. Michele Green, a board-certified dermatologist in NYC, tells BuzzFeed that it takes between five to six sessions of laser hair removal in order to see phenomenal results. 7. Your appointment can take anywhere from 20 minutes to an hour. View this photo on Instagram instagram.com It all depends on the area you're having treated. Underarms and bikini lines tend to be quick treatments, but other areas like the legs or back can take a little longer. 8. Getting laser hair removal near the eyes is a BIG no. Tap to play or pause GIF Tap to play or pause GIF Warner Bros. Listen, I know cosmetic lasers may LOOK all pretty and innocent with their colored beams of light, but they can be seriously dangerous around the eyes. No matter where you're receiving treatment, you should always wear eye protection, which your physician will provide. 9. You can’t make an appointment for a full-body laser hair removal treatment. View this photo on Instagram instagram.com If someone tells you that you can, RUN FAR AND FAST. There's only a certain amount of cosmetic laser light and heat that your body should safely absorb each session. 10. If you want to see results, you have to be consistent. View this photo on Instagram instagram.com Hear me out: There's a good reason for this. Your hair follicles are on their own growth cycle. People who see the best results typically go in for treatment every four to six weeks in order to maximize the potential of zappin' the most follicles. This time frame allows the dead hair shafts to fall out on their own. 11. You should see prominent results after three months. View this photo on Instagram instagram.com I am the QUEEN of impatience, but trust me, you'll want to stick with it. After the first few treatments you might not see much of a difference, but I started to notice a dramatic drop in my unwanted follicles after the three-month mark — and even more after that. 12. Some hair and skin types can be a little harder to treat — but not impossible. View this photo on Instagram instagram.com Dark hair follicles are usually easy to treat because, again, the laser targets the hair's pigment. This is also why gray, white, blonde, and red pigments can be tricky. Darker tones can also be harder to treat, but not impossible. "I do have a different laser that can treat darker skin types such as African-American and tan skin," Green says. The ND:Yag laser is typically best for this. However, it's best to talk to your physician first in order to avoid pigment discoloration. 13. The treatment itself isn't particularly relaxing. Tap to play or pause GIF Tap to play or pause GIF HBO I'll be real with you. Every time the laser fires, it feels like someone is snapping you with a rubber band. Sounds SUPER enticing, right? But the long-term result should be worth the half hour of pain. 14. Lather up that sunscreen post-treatment. Tap to play or pause GIF Tap to play or pause GIF Via butactuallyy.tumblr.com Listen, sunscreen should be your BFF in general, but definitely use it after your treatment. Your skin will be sensitive — even if it doesn't feel like it — and you need to protect it as much as possible. 15. DO NOT wax or pluck after your treatment, though. Tap to play or pause GIF Tap to play or pause GIF Warner Bros. Shaving is totally fine, but PUT DOWN THE TWEEZERS. Pulling out hair follicles after your laser hair removal treatment hinders the process. Your unwanted hair needs to fall out on its own in order to see the best results. 16. Also avoid perfumes, deodorant, and hot showers.

So, is laser hair removal actually SAFE? View this photo on Instagram instagram.com "Laser hair is a safe and effective treatment when performed in a board certified dermatologist's office," Green says. "It gives permanent hair reduction and is safe, fast, and effective." 18. And the most important question… is it ~worth it~? Tap to play or pause GIF Tap to play or pause GIF Paramount Pictures A THOUSAND TIMES YES, in my humble opinion. Laser hair removal doesn't guarantee to remove 100% of your unwanted hair, but the few stragglers that do grow back are pretty much unnoticeable. I've gone two months without shaving my legs before, and gone are all my prickly woes. Basically, enduring laser hair removal treatments equals YOUR FREEDOM FROM THE STUBBLE STRUGGLE.
