Before you spend another dollar on eye

0:01

creams, I need you to do one quick

0:03

experiment with me. Grab a mirror. Oh,

0:05

wait. Because the most common mistake

0:07

that people make with dark [music]

0:08

circles is treating like they're all the

0:10

same. If you've ever Googled how to get

0:12

rid of them, you've probably seen the

0:14

same generic advice. Sleep more, drink

0:16

more water, use vitamin [music] C. And

0:18

while that's not necessarily wrong, it's

0:20

completely misses the point. Dark

0:21

circles can come from at least four

0:23

different [music] causes: shadows,

0:25

pigmentation, visible veins, and dull

0:28

and textured [music] skin. Each one

0:30

needs a completely different fix and

0:32

using the wrong treatment can be a total

0:34

waste of time and money. So, in this

0:35

video, we're going to do a simple

0:37

experiment together, figure out [music]

0:38

exactly which type you have, and talk

0:40

about what you can actually do about it.

0:42

By the way, if you're new here, my name

0:44

is Dr. Danny Guo. I'm a cosmetic and

0:45

surgical dermatologist. And on this

0:47

channel, I talk about skincare, skin

0:49

health, and dermatic treatments without

0:51

the hype. So, for this experiment,

0:52

you're going to need two things: a

0:54

mirror and a light source above you.

0:56

Your regular room light is totally fine.

0:58

Step one, hold the mirror at eye level

1:00

and look straight into your own eyes.

1:02

Remember what your dark circles look

1:04

like and the color and depth and shape.

1:06

Step two, tilt your head up and then

1:08

move the mirror with you so you can see

1:10

your own eyes. Now look at your eyes

1:12

again. Are they the same? Are they

1:13

better? Or are they gone completely? If

1:15

they're completely gone or basically

1:17

disappeared, then you're dealing with a

1:19

shadow. Your dark circles are literally

1:21

just shadows being cast under your eyes.

1:23

If they're not better at all and the

1:25

color looks brown, then that's

1:26

pigmentation. We're dealing with melanin

1:28

in the skin. And if you see blue or red

1:30

discoloration on the inner corner of

1:32

your lower eyelid, like right here,

1:34

that's veins shining through thin skin.

1:36

And if your answer was kind of all of

1:38

the above, then you might have a

1:40

combination of things. Don't worry,

1:42

we're going to talk about how to manage

1:44

each one of these. The shadow is

1:45

probably the most common type of dark

1:47

circle, and it's not actually a

1:49

pigmentation issue at all. It's purely

1:51

structural. There are two ways that this

1:53

can happen. First, your lower eyelid is

1:56

protruding, kind of pushing forward

1:59

beyond the level of your cheek. And when

2:01

light hits it from above, it casts a

2:03

shadow downwards. That shadow is your

2:05

dark circle. The second possibility is

2:07

the other way around. Your lower eyelid

2:10

is more sunken in compared to the

2:12

position of your cheek. This also

2:14

creates a shadow on your lower eyelid

2:15

instead of on your cheek, but the result

2:17

looks very similar. So, what do you do

2:19

about it? Well, it depends on which

2:21

shadow issue you actually have. If it's

2:24

your eyelid that is protruding, meaning

2:26

your eyelid is a little lax and hanging

2:28

forward in early stages, resurfacing

2:30

lasers, can actually help tighten the

2:32

skin. More significant cases may need

2:35

surgery. Specifically, it is a procedure

2:37

called blleroplasty. That's when a skin

2:39

surgeon removes or repositions the

2:41

tissue of the lower eyelid. It sounds

2:43

intense, but it's one of the most

2:45

effective long-term fixes out there. And

2:47

if surgery doesn't sound like [music]

2:48

something you want to do, a skilled

2:50

injector can also place some filler in

2:52

the cheek below the bulge to camouflage

2:55

the difference between your lower eyelid

2:57

and your cheek. Now, if it's the hollow,

2:59

sunken lower eyelid, then this is a

3:01

volume loss issue. One option here is

3:04

[music] filler, specifically something

3:05

called teertro filler, where a small

3:07

amount of hyaluronic acid filler is

3:09

placed in the hollow to restore the

3:11

volume. When done well, the result

3:13

[music] is genuinely remarkable. the

3:16

shadow disappears almost immediately.

3:19

The downside though is that this is

3:20

actually a [music] very technically

3:22

challenging procedure and patient

3:23

selection is extremely important. But

3:25

unfortunately, while most injectors

3:27

[music] do not do this very well, many

3:29

claim that they do. Quick note, if you

3:31

want to look into the tear trough

3:33

filler, go to a board-certified

3:34

dermatologist, not just anyone with an

3:36

Instagram page. [music] The under eye

3:37

area is extremely delicate, so choose

3:39

your injector wisely. Now, let's talk

3:41

about pigmentation. If your experiment

3:43

showed that your dark circles are brown

3:45

and that they didn't get better when you

3:47

looked up at the light, then you've got

3:49

pigmentation. This means there's extra

3:51

melanin sitting in the skin under your

3:53

eyes. The good news, this is one of the

3:55

more treatable types and you can start

3:57

right now at home with skincare. Just to

4:00

be clear, you don't actually have to use

4:01

things that are called eye creams

4:03

because there is no regulation for that

4:05

term and it's often just really

4:06

expensive moisturizer. Instead, you're

4:08

going to want to look for some products

4:10

with the following ingredients. Number

4:12

one, transexamic acid. This has become

4:14

one of my personal favorite newer

4:16

brightening ingredients. It works by

4:18

blocking the signal that tells your skin

4:20

cells to produce extra melanin.

4:21

Genuinely impressive results for

4:23

pigmentation. Number two, nioinamide.

4:26

It's great for skin brightening and has

4:27

a solid safety profile around the eye

4:29

area. Number three, vitamin C. Classic

4:32

antioxidant and melanin inhibitor. Look

4:34

for a gentle formula with eloscorbic

4:36

acid if you can. And finally, retinoid

4:39

in an eye cream. This is a slow burn,

4:42

but retinoids increase cellular

4:44

turnover, which help fade pigmentation

4:46

over time. You're going to want to start

4:47

slow, like maybe two to three nights a

4:49

week, and then slowly work your way up

4:51

because the skin around your eyes is

4:53

very thin and can easily get irritated.

4:55

As with all skincare, results are not

4:57

going to happen overnight. We're talking

4:58

like 8 to 12 weeks of consistent use

5:00

before you see significant improvement.

5:02

So, patience is part of the prescription

5:04

here. All right, now let's talk about

5:06

blue red discoloration. This happens

5:08

from veins showing through the skin

5:10

under your eyes. And I'm going to be

5:11

honest here. This is probably one of the

5:13

trickiest types to treat. What's

5:15

happening here is the skin under the

5:17

eyes is very thin. Thin enough that you

5:19

can see the blue and red blood vessels

5:21

underneath, especially on the inner

5:23

corner of the lower eyelids. It can look

5:25

like a bluish purple shadow, but it's

5:28

actually just your veins. There are two

5:30

main options here. The first [music] is

5:32

to directly target the blood vessels

5:34

themselves. And for this you can either

5:36

use a caffeine-based eye cream to

5:38

temporarily [music] cause vasal

5:39

constriction thus reducing the

5:41

appearance of the blue red discoloration

5:43

or you can use a vascular laser like a

5:46

pulsey laser. The V-beam for example is

5:48

a well-known example of a vascular

5:50

laser. These lasers specifically target

5:53

the hemoglobin in those blood vessels

5:55

and selectively destroy the blood

5:57

vessels without hurting your skin. As

5:59

with most lasers, this is done in a

6:01

dermatologist office or a laser clinic

6:03

setting. [music] The second approach is

6:04

to thicken the skin above the blood

6:06

vessels with skincare so the vessels are

6:08

less visible. The best ingredients for

6:10

this are probably retinoids which

6:13

stimulate collagen production over time

6:14

making the [music] skin thicker and less

6:16

translucent. It takes time but it's a

6:18

real genuine improvement. So for most

6:21

people if your dark circles are blue red

6:23

discoloration combining both approaches

6:26

specifically some laser work plus

6:28

consistent retinoid [music] use tends to

6:30

give the best results. So, the last one

6:32

we're going to talk about in this video

6:33

is dull skin. And this one is sneaky

6:35

because it doesn't look like a

6:37

traditional dark circle. It makes the

6:39

whole under eye area look flat and

6:41

tired. Here's the best way I can explain

6:43

this with this tin foil. When it is

6:45

smooth and flat like this, it will

6:47

reflect light beautifully, like very

6:49

glowy glass skin. But if we introduce a

6:51

bunch of texture to the tin foil, like

6:53

creases and folds, it becomes way less

6:56

glowy because all those tiny wrinkles

6:58

scatter light in every different

7:00

direction instead of reflecting it

7:01

cleanly. [music]

7:02

That's exactly what happens when fine

7:04

lines, dryness, and texture take over

7:07

the under eye. Light just doesn't

7:08

reflect off your skin cleanly anymore.

7:10

The result isn't really a dark circle.

7:12

It's just a dull, non-reflective

7:15

surface. [music] The good news though is

7:16

that this type responds very well to

7:18

straightforward skincare. The first one

7:20

you'll want to add in is a moisturizer.

7:22

And I mean like a dedicated rich eye

7:25

cream, not just whatever you're using on

7:27

your forehead. The under eye skin is

7:28

thin and loses moisture really quickly.

7:31

So keeping it hydrated is going to make

7:32

a real visible difference. After that,

7:34

you're going to want to add in an

7:35

ingredient like vitamin C and nioinamide

7:37

because both of these can help with skin

7:39

brightness. The nycinomide can also

7:41

improve skin barrier and soothes

7:42

irritated skin which improves skin

7:44

radiance or how reflected the skin is.

7:46

For fine lines specifically, you're

7:48

going to want to go back to that retinol

7:50

cream because over time they will

7:51

stimulate collagen, smooth texture, and

7:53

get that reflective quality back.

7:55

Fractional resurfacing lasers like CO2

7:57

and ultra clear can also be very

7:59

effective for fine lines of the lower

8:01

eyelids, but you should first speak with

8:03

your dermatologist to make sure that

8:04

it's appropriate for you. So, there you

8:06

have it. four of the most common causes

8:08

of dark circles under the eyes. And of

8:10

course, you can have a combination of

8:11

more than one. If there is one point

8:13

that you take away from the video today,

8:15

it's that not every dark circle is the

8:17

same. So, rushing out to buy the latest

8:19

viral eye cream, it may end up just

8:21

being a complete waste of money if it

8:23

doesn't target the specific cause of

8:24

your dark circles. I hope this video

8:26

helps you understand the actual cause of

8:28

your dark circles and what you're

8:30

actually looking at when you see [music]

8:31

darkness under your eyes so that you can

8:34

make a more informed choice as a

8:35

consumer before spending your

8:36

hard-earned money on something you saw

8:38

on Tik Tok. [music] If you found this
