1
Vaping is seriously damaging your skin.
2
It's contributing to premature skin aging,
3
not to mention it's really,
4
really, really bad for your health.
5
And a lot of young people have been sold a pack of lies when it comes to vaping.
6
And in this video, we're gonna highlight how damaging vaping is,
7
not just for your skin,
8
but for your total body health,
9
what exactly it does to you.
10
Cutting the vape out takes priority over your skincare routine.
11
Well, vaping or e-cigarettes, they're handheld devices.
12
They heat a liquid into an aerosol that you inhale.
13
That liquid often contains nicotine,
14
as well as propylene glycol, vegetable glycerin, and flavorings.
15
The vaping industry has marketed these as a safer alternative to smoking cigarettes.
16
They even have sold it as a safe and effective way for quitting cigarettes.
17
That's misleading.
18
Many so-called nicotine-free vapes actually still contain nicotine.
19
Because vaping in the grand landscape of things is relatively young,
20
we're still beginning to understand the effects vaping has on the body, including the skin.
21
But before we zoom into the skin,
22
let's talk about the effects vaping has on your body.
23
E-cigarettes have been linked to lung inflammation,
24
chronic cough, and worsening respiratory issues.
25
They deliver nicotine.
26
Nicotine is highly addictive.
27
Many vaping devices deliver nicotine in a high concentration.
28
The The American Medical Association warns that vaping can harm the heart,
29
impair brain development in young people,
30
and lead to long-term dependence.
31
Meaning you are hooked, you are a customer for life,
32
which I imagine is what the vaping industry wants.
33
They want to hook people young and get them addicted so that they remain a customer for life.
34
It's not a harmless habit.
35
Here's what we know about how vaping affects your skin.
36
First, it's been shown to impair wound healing,
37
similar to how smoking cigarettes is well established to impair wound healing.
38
Nicotine restricts blood flow.
39
Basically, that means less oxygen,
40
fewer micronutrients, growth factors needed for healthy skin.
41
This really slows down your skin's ability to repair itself.
42
Second, vaping has been linked to contact dermatitis and allergic skin reactions,
43
especially around the mouth and the hands.
44
Common culprits are nickel, surprisingly.
45
Nickel from the heating coils plus the chemical flavorings act as irritants and allergens.
46
Also, there are cases of documented skin conditions that significantly worsen with vaping.
47
These include discoid lupus, morphia,
48
and periorificial dermatitis, not to mention burns.
49
Yes, burns have been known to happen from exploding batteries or devices overheating.
50
These have caused cases of real injury to the thighs and the hands.
51
Let's get into the nitty-gritty about the science behind how vaping speeds up skin aging.
52
First of all, vaping increases inflammation in the skin.
53
Lab studies show that e-cigarette usage worsens skin cell health integrity and that it increases certain pro-inflammatory cytokines.
54
Second, vaping generates a lot of oxidative stress.
55
That means more free radicals,
56
which can damage your collagen and elastin.
57
This leads to wrinkles, dullness, and accelerated skin aging.
58
Third is related to the nicotine itself.
59
Nicotine, again, causes vasoconstriction, which means your skin is not getting the nutrients it needs to heal,
60
to repair, to recover.
61
And finally, the heat and the chemicals from vaping,
62
they can compromise skin barrier integrity,
63
making your skin more vulnerable to irritation, redness, and sensitivity.
64
Symptoms of like burning, stinging, discomfort.
65
So while vaping may seem harmless on the outside it is slowly poisoning your body
66
and that's gonna show up on your skin because hello your skin is a window to what is going on internally.
67
I want to address some of the biggest myths that I hear perpetuated with regards to vaping.
68
Number one is that vaping is a safe alternative to smoking cigarettes.
69
The truth is, vaping is not harmless.
70
And many of the long-term risks are still unknown,
71
especially when we're talking about the skin.
72
And I want you guys to keep that in mind because 20 or 30 years from now,
73
I don't want people coming on the internet
74
and being like they told us they told us these were
75
safe all along they knew they were not um no we
76
don't know how safe they are we're not telling you they're safe okay this is documented evidence
77
that doctors are not telling people
78
that vaping is safe devices are widely different as well not
79
to mention the devices themselves they vary a lot with regards to the heat the chemicals they use
80
and the amounts of nicotine so it's really impossible to say
81
that anyone vape is safe And just because the skin effects may not seem as obvious to you right now,
82
as perhaps the lung effects might be,
83
which perhaps you're already experiencing,
84
it doesn't mean that they're not real and you won't regret this down the road.
85
All right.
86
So if you are vaping, what can you do?
87
Are you just stuck now forever,
88
permanently latched onto this thing?
89
I encourage you to quit.
90
Quitting is possible.
91
It's the single best thing you can do right now for your skin,
92
for your overall health, for your anti-aging, looks-maxing goals.
93
If you need help, talk to a doctor, a physician.
94
There are all sorts of nicotine replacement therapies and quitting tools out there that can be a tremendous asset to you.
95
You just have to ask for help.
96
And your healthcare provider, that's the best place to start.
97
Also, don't delude yourself into thinking that if you just use a vitamin C serum or some antioxidant serum,
98
it'll protect you from all that extra oxidative stress.
99
Okay, all right, all right.
100
If you wanna believe in magic,
101
most importantly, pay attention to your skin.
102
If you're developing a rash,
103
skin skin problem, don't hesitate to see a board-certified dermatologist for the correct diagnosis and treatment plan.
104
Don't ignore your skin.
105
It gives it many, many clues.
106
When should you bother to see a dermatologist?
107
While seeing a health care provider is a great place to start for quitting,
108
when should you take it to the step of seeing a board-certified dermatologist for the skin consequences of vaping?
109
If you've developed redness, itchiness on your hands or around your mouth.
110
Those can be warning signs of skin conditions related to vaping and a dermatologist can help address those.
111
If you've noticed that your cuts or wounds are slowly healing,
112
if you've developed skin rashes that don't seem to go away,
113
definitely see a board certified dermatologist.
114
Whether it's related to the vaping or something else,
115
very important to clarify early on what it is that you have going on so that it can be treated appropriately.
116
Dermatologists are the experts on skin conditions,
117
including skin conditions related to the vape.
118
Not only can they nail the diagnosis and tell you what it is you have,
119
they can help guide you as to how to get rid of it.
120
Vaping is not good for your health.
121
It's not just a skin health problem,
122
it is a total body health problem.
123
Yeah, the evidence is still emerging,
124
but what we know so far is that vaping clearly is not good for you.
125
It's only a matter of time before we learn all of the true consequences this has on your total body.
126
I really hope this video was helpful to you guys and that you learned something.

什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
