Very tasteful art!
2
Oh, you hate it?
3
You are not alone!
4
One in four people with a tattoo  regret it, 25 million people in the US.
5
Getting ink carved into your body permanently has exploded in popularity in the last few  decades, especially among Millennials.
6
Often their tattoos were about a current cultural  thing, a moment in their life, following a trend, expressing individuality or about feeling  like being part of something greater.
7
This is all fine and good but  as people age they often stop identifying with what their younger  versions wanted on their skin forever.
8
Or sometimes their tattoos simply  just look ugly or have aged badly.
9
And so today laser tattoo removal is booming,  being as normalized as dentist appointments.
10
Which is wild since lasering a tattoo away is one  of the most metal things you can do to your body.
11
A high tech procedure that is extremely painful  and makes your skin explode from the inside.
12
How does it work?
13
We explained what a tattoo is in  detail before, but in a nutshell: From the perspective of your cells  your tattoo is a mountain range of colourful boulders, from small to building-sized.
14
Injected deep into your dermis by violently  ripping huge wounds with gigantic needles.
15
Your body is trying hard to destroy  the tattoo, but the ink particles are way too large to be transported away  and your immune cells can’t eat them.
16
So they do the next best thing: Keeping the ink trapped in a prison of flesh.
17
This is why tattoos remain forever,  millions of your cells give their lives to keep the ink in place – when  they die new ones take their place.
18
In principle removing a tattoo is very easy: Just destroy the ink particles.
19
The hard part is to do that  without destroying you.
20
Amazingly the best way is still  to blast you with a deadly laser.
21
Lasers, UV light, wifi or  x-rays are all the same thing: Electromagnetic radiation, photons that travel through space at the  speed of light in the form of a wave.
22
The more energetic they are, the higher their  frequency and the more punch they carry.
23
Imagine your skin as jelly and  your tattoo as crumbs of toast.
24
If you shine a flashlight against  it, most light passes right through the jelly – but the darker toast crumbs  absorb more light and are clearly visible.
25
Likewise, certain laser frequencies mostly  pass through your skin without doing damage, while dark ink particles soak them up.
26
Depending on the colour of your  tattoo, we need different lasers.
27
Red ink reflects red light but absorbs  green light – so you need a green laser.
28
Black ink easily absorbs all types of  light and is the easiest to remove.
29
But even with the right colour, tattoo removal  lasers are still pretty powerful and can still leave horrible injuries, scars, or  change your skin colour permanently.
30
So instead of shooting your skin  with a continuous ray of death, modern tattoo removal lasers shoot  an extremely brief pulse – a packet of electromagnetic energy that lasts  about a few trillionoth of a second.
31
So short that the beam ends before  the first photon even hits the skin!
32
Ok, enough theory.
33
Let’s laser your mistake away and experience  the fun of tattoo removal together!
34
But laser removal is expensive, so let’s  start by taking care of your finances.

44
And now … Let’s Laser A Mistake Away Take a deep breath, this is going to hurt.
45
Let us slow down time… zapp The pulse of high energy photons hits  your arm nearly at the speed of light, shooting through the dead layers of  the skin, passing into the dermis.
46
Most cells are like jelly to the  laser and don’t absorb much energy, escaping its deadly power unharmed.
47
The flood of photons moves  on and reaches the mountain range of ink embedded deep in the  prison of your flesh and cells.
48
Only a nanosecond, a billionth of a second,  has passed but now things escalate rapidly.
49
As the photons hit the black ink on  a molecular level, they smash into electrons and are absorbed and annihilated –  transferring all of their energy into them.
50
This sudden influx of energy  almost instantly turns into a massive amount of heat that has nowhere to go.
51
The ink particles burn up to a seething hot 600  degrees, hot enough to make iron glow red hot.
52
Overwhelmed by the sudden heat the  ink particles expand rapidly and are mechanically stressed to the max, violently  ripping and fracturing, almost exploding.
53
The mountain range cracks into millions of  seething hot pieces and a bit of hot ink dust.
54
Which would not be that bad if this  was not going on inside your skin.
55
Water in your tissue and inside your cells  instantly vaporizes and expands quickly.
56
Ripping cells apart and growing into gigantic  caves of hot steam bubbles inside your skin.
57
This sudden expansion creates a  shockwave that hits tissue nearby, causing more mayhem and damage.
58
Your cells that were keeping the tattoo in  place a moment ago are having a really bad time.
59
If they had kept tattoo particles safely stowed  inside of them they are cooked or ripped apart.
60
The cells that surrounded the ink mountains are gravely wounded or burned alive  by the sudden heat or steam.
61
A few tiny blood vessels in the  area are ripped apart violently.
62
Thousands of your cells are dead or hurt.
63
And then the next laser pulse hits again, and again, moving over the tattoo  like an orbital bombardment.
64
From your perspective all of this is happening  so fast that you only notice one thing: A sharp pain like being electrocuted, a smell like  burnt hair and most disturbingly, a loud crack.
65
Where the laser hits your tattoo  instantly turns white – which is called frosting and is the bubbles  of hot gas expanding under your skin.
66
To ease the pain the area is often cooled  with a stream of cold air for a moment, before the laser moves on again.
67
Inside your skin the tattoo is now a  crushed mountain range of carnage and death.
68
The cooked and ripped remains of cells float in a mix of hot ink and water  vapor that are cooling down.
69
Many more cells are injured and  are chemically screaming for help.
70
It's like an internal burn wound.
71
The Brutal Aftermath Hundreds of thousands of  immune cells like Macrophages, stream into the wound to clean up the mess.
72
They order inflammation so your blood  vessels open up and water rushes in.
73
Your wounded skin starts to swell up and turn red.
74
As your cells begin cleaning up  casualties and helping with wound healing they also meet loads of hot ink particles.
75
It‘s now that your tattoo is  actually being removed – the same immune system that kept it in  place is now helping to clean it up.
76
Many of the smallest particles are  simply rinsed away by the flood, while Macrophages devour some of them  and transport them to your lymph nodes.
77
If possible they will be broken down  further and ejected from your body via your urine – if not then they will just collect  inside your lymph nodes and stay there, probably for the rest of your life.
78
So hopefully you got the tattoo  from a pro and the ink is not toxic.
79
But the majority of ink particles are either still  too large or there are just too many of them.
80
So your immune and skin cells  – in a brave effort to protect you – once again swallow and bind them in place.
81
This is why a laser tattoo removal usually  takes between 5 and 12 sessions – each time a part of the tattoo is transported away and  an even larger one is cemented in place again.
82
You get to enjoy watching this  process happening in real time.
83
Within the first few hours the frosting under your skin fades and the skin around the  tattoo feels like a bad sunburn.
84
Red, swollen and stingy.
85
Often it rises with fluid filled burn  blisters that you should leave alone.
86
As the pain calms down it is replaced by soreness.
87
Over the next few days the wound will remain red, swollen and tender and begin to itch –  the itching is a direct consequence of your immune cells actively healing you,  so maybe that gives you some comfort.
88
After about a week the wound may crust over as  new healthy and pink skin replaces injured skin.
89
Things slowly get back to normal.
90
Your tattoo will usually be noticeably lighter, although not that much if  this was your first session.
91
Over the next few weeks it will  get a bit lighter still as your immune system keeps transporting parts of it away.
92
Modern laser tattoo removal has gotten very good, so if you chose an experienced professional  you should be completely healed after two months – but if you did not or if you  had the procedure done with older tech, sometimes there might be a slight scar or the  colour of your skin may change slightly in places.
93
Although this is pretty rare nowadays, please do your research when deciding who  you’re going to allow to shoot lasers at you.
94
In the best case, after a number of sessions, your tattoo is no longer visible,  or only very, very faintly.
95
Whetherit will disappear completely  depends on the size of your tattoo, the colours that were used, how  deep the ink was injected and to a degree – how good of a job your  body does cleaning up the mess.
96
New year, new you?
97

103
We also made it as beautiful and fun as possible  (as taking care of your health should always be).
104
After the Gratitude Journal and the Habit Journal this is the third part in our  bestselling journal series.
105

Phương Pháp Shadowing Là Gì?

Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
