  • [groaning]

  • - Today we're gonna be looking at all things nails.

  • Nail care, nail polish, nail polish remover,

  • and what products are right for you.

  • I'm Jessica, your unofficial but official beauty expert

  • with my best friend, my beauty microscope,

  • and together we will create science.

  • [upbeat music]

  • Okay, let's take a look

  • at my bare nails under the microscope.

  • There's glitter, there's still glitter from the last video.

  • Is my finger sweating?

  • I just saw glistening, okay, everyone relax.

  • These two little things that look like fish scales

  • that you see and a lot of this stuff right here,

  • these are hangnails.

  • Hangnails are loose skin caused by trauma around the nail.

  • Nail biting, doing a lot of physical labor with your hands.

  • My hangnails are caused from gardening

  • 'cause I love plants.

  • See?

  • Sweat, what is that, sweat?

  • Look at that, do you see it, what is that?

  • You know what?

  • You're getting a little embarrassed, it's okay.

  • I love you no matter what you look like.

  • [optimistic music]

  • Check.

  • Up next we're gonna do a little bit of nail maintenance.

  • The purpose of your cuticle

  • is to create a seal between the nail plate

  • and the rest of your skin.

  • That seal keeps out micro-organisms, fungus's, and viruses.

  • We're gonna start with pushing back one of my cuticles.

  • I just let the weight of my hand glide the cuticle back.

  • And wherever it stops, I just let it stop.

  • That's probably really horrifying to see up close.

  • Okay, now I'm gonna trim a little bit of my cuticle,

  • but before I do that, I just wanna say

  • the more you trim, the more your cuticle will grow.

  • Your body wants there to be a cuticle,

  • so it's going to make it grow more and more and more

  • the more you cut it back.

  • [lively music]

  • There you go.

  • [gags]

  • Look at that little piece of cuticle.

  • [squealing]

  • That's so gross.

  • [laughing]

  • Wow, I feel like I'm beheading my friends.

  • I like the bare nail push.

  • It looks more moisturized, it looks healthier.

  • The trimmed actually kind of looks like I caused

  • a little bit of trauma on my nail.

  • Moving onto bitten versus cut nails.

  • And biting your nails includes not just the nail plate,

  • but also the skin around your nails.

  • By biting your nails,

  • you're causing tiny fissures in your skin

  • that allow micro-organisms in.

  • [gags]

  • That being said, I do wanna see what

  • a bitten nail looks like under the microscope.

  • I literally cannot bite because mine are too strong.

  • So, we had somebody else come in

  • and bite their nail.

  • Oh, that nail.

  • Looking at this, you can see the jagged edge,

  • and another thing that happens when you bite your nails,

  • because it's uneven, that leads you to continue

  • to bite to try and even out the nail.

  • Let's move onto trimming, let's do it.

  • Side.

  • Side.

  • Top.

  • Let's look under the microscope.

  • You guys can see here that it's a lot smoother

  • than the bitten nail,

  • but you still have those two points

  • of raggedness from the edge of the clipper.

  • So, we're gonna move onto filing.

  • We're gonna start with your standard drugstore nail file

  • and then we're also gonna try out a glass one.

  • Drugstore and we're gonna do under the microscope.

  • As you guys can see, as I file,

  • I file in one direction.

  • You don't wanna saw back and forth

  • 'cause that can further damage your nail.

  • You can see the black or the little pieces

  • of the emery board which leads me to my next fact.

  • Emery boards sometimes are made of cardboard

  • or styrofoam, they're porous.

  • So, sometimes bacteria can get in them

  • and they're not the most sanitary thing to use.

  • Now we have the glass file

  • which we're gonna check out underneath the microscope.

  • Okay, now we're gonna file this down.

  • And this is a really fine file,

  • so you're not gonna see as many particles

  • flying around as we did with the last file.

  • It's like powder.

  • Looking at both of the nails,

  • I can see the coarser file, there's way more debris.

  • Honestly, not as smooth of an edge

  • as the glass file gives you

  • and the particles are much finer with the glass file.

  • Once you put it in glide,

  • your nail kind of does all the work for you.

  • Hydration is very important.

  • Creating science.

  • Next we're gonna try on some nail polish.

  • First I'm gonna put on base coat so my nails do not stain.

  • Done.

  • We are gonna go with the affordable brand first.

  • It's kind of a streaky formula.

  • I also love to paint my whole finger

  • because I am a slob and then I like

  • to go in with nail polish remover

  • and then clean up my nail, that's how I paint my nails.

  • That's the truth, that's who I am, it's a safe space.

  • It's very shiny, you can see some of the streaks.

  • It almost looks like there's texture on my nail,

  • but that's really just the streaks.

  • Okay, I'm gonna put on another layer

  • and see if that helps.

  • I'm gonna do it really quickly.

  • It's a little bit better, more shiny.

  • So the key is two coats.

  • Now we're gonna do the expensive nail.

  • This one is a much more runnier formula.

  • No streaks.

  • And because we had a finer brush,

  • it was a lot easier to not paint on the sides.

  • It's much cleaner edges.

  • Thinner formula but a better color payoff which is wild.

  • I think both of them are really great.

  • The more affordable one dries faster,

  • but you need two coats to get that desired color payoff

  • and the more expensive one gives you

  • a really nice shine and a great color payoff

  • with just one coat.

  • Oh, sorry.

  • She gets very hot.

  • Oh my god, oh speeds, that's ridiculous.

  • We're gonna do some fun nail art.

  • First thing I'm gonna check out is this Crackle polish

  • and we're gonna watch it dry under the microscope.

  • [groaning]

  • - [Woman] Oh no.

  • - Oh no, that's disgusting, looks like rotting flesh.

  • I'm not gonna say his name 'cause brand,

  • but it's that guy's face.

  • And you know what guy I'm talking about,

  • it's that guys face.

  • So, this has more alcohol in the formula,

  • causing it to dry and separate.

  • Next!

  • Stickers.

  • No, roses.

  • [gasps]

  • Cacti!

  • Aw, little plants.

  • Oh my god, I gotta do the plants.

  • Oh my goodness, this one looks like she's crying.

  • I get it, so I'm gonna use her.

  • Here she comes.

  • Oh wow, I'm having the time of my life.

  • Oh no.

  • I just folded her in half on accident.

  • Hi!

  • Oh my goodness.

  • Look!

  • Look at the little cacti.

  • And to keep the stickers on,

  • you can just put a top coat on to seal it.

  • [upbeat music]

  • Am I going to be able to do it?

  • Now to the fun section.

  • [trilling]

  • Those are special effects.

  • We're gonna try out two nail products.

  • One of them is a matte coat

  • and then we're gonna try another nail polish

  • that's a fun, glittery, holographic polish.

  • So, this is a top coat that matte-ifies.

  • It's gonna take out all of the shine.

  • So I only painted half the nail.

  • You can see this looks a shade lighter,

  • almost pink-like, versus the high shine of the red.

  • If we could get even closer

  • on a super, super, super microscopic level,

  • we wouldn't see a flat, smooth, shiny surface,

  • we would see tiny little divots, right?

  • Because there's texture or pattern on top

  • that makes it matte.

  • Now we're gonna try the fun, shiny holographic nail polish.

  • I'm really excited for this one.

  • Fun!

  • Oh, yes, come through party.

  • Actually, you can see a little bit of my nail

  • through the nail polish.

  • I wanna say it's a more natural look, but it's not.

  • I already told you about how I do,

  • I just paint my whole finger, girl.

  • Paint the whole finger, girl, let it dry.

  • And you know what?

  • I'm telling you that you go back

  • with nail polish remover and clean it up,

  • but I just take a shower

  • and it peels off in the shower, okay?

  • Just paint your whole finger, let it dry,

  • and then take a shower.

  • - [Woman] Jess, this is bad advice.

  • [laughing]

  • - Oh my god, I'm just saying it's a safe space

  • for us out here who are not amazing nail techs, okay?

  • I feel you, I feel you.

  • This nail polish has tiny little particles

  • made of silica which are suspended in the polish

  • and act as little mirrors that make all the glitter

  • and all the shine and all the colors.

  • They're both fun finishes,

  • but I think we all know glitter is where it's at

  • and glitter is not just a look, it's a feeling, okay?

  • Onto some longer-lasting options.

  • We're going to do gel and then we're gonna try dip.

  • Not the tobacco.

  • Gel cures with a UV or an LED light,

  • but today we're gonna use a UV light.

  • So I'm gonna put on some sunscreen.

  • You wanna aim for SPF, 30 or higher,

  • because this is a UV light just like the ones

  • that you use in tanning baths.

  • We're going to start with a foundation.

  • This smells terrible.

  • Oh my gosh.

  • Between every single layer,

  • we have to cure and set the product.

  • I put on the foundation and now we're gonna press.

  • You set it and you forget it like a rotisserie chicken.

  • Okay, this is all set, now we're gonna add our color.

  • It looks a little bumpy.

  • Now we're gonna set in the mess with our top coat.

  • Oh.

  • I might of fixed it.

  • [laughs]

  • Heard that feedback.

  • Okay, so it's not totally fixed.

  • She's done!

  • [applauding]

  • So,
