The worst thing you can do for your skin is go tanning.

Not only do they cause skin cancer, but they also accelerate aging rapidly.

Hi, I'm Dr. Maneeb Shah, and this is Skin Support. ["Skin Support"] So, at Young Forehead, great username, should you or shouldn't you pop your pimples?

All right, let's settle this debate right now.

Anyone who follows me knows I am very much against popping your pimples.

We have to think about what causes a pimple or where is the pimple in your skin in general.

It's actually stuck inside your hair follicle unit, or basically inside your pore.

So, this pimple is a little puss ball filled and stuck inside this pore.

Now, it's restrained there, which is fine.

It's not gonna cause any scarring at this point.

The second that you pop it, you actually rupture that hair follicle and it damages the surrounding collagen because of all that inflammation.

So, definitely don't pop your pimples if you don't want scarring, if you don't want that post-inflammatory hyperpigmentation that sticks around forever.

There are so many good spot treatments out nowadays that eliminate your pimples pretty quickly without you having to pop them.

Mugumbo Inc. asked, why is there no cure for hair loss?

I wish there was because everybody, including myself, suffers from hair loss.

Hopefully one day in my lifetime, we will have an answer.

But all of our cells go through basically a programmed death cycle.

They're all meant to replicate a certain amount of times and then eventually die off.

And our hair cells are exactly the same way.

And once they die off, you really can't get them back.

And so, we have treatments in dermatology that can actually stop the hair loss process, slow the hair loss process, maybe get you a few hairs back, but nothing that's a complete cure at this time.

But if we ever have a cell that we're gonna continue to replicate forever and ever and never die off, that's exactly what cancer cells do.

But we need to find something in between that lasts long enough that we can produce hair shafts forever, but not last long enough that it turns into a cancer.

Rockinit4U asks, how safe are tanning booths?

As a result of that, I ended up developing skin cancer at the age of 31, when nobody in my family has ever had skin cancer.

And I went tanning probably over a hundred times.

So, we know that tanning booths are gonna increase your risk of skin cancer.

We know that it's gonna accelerate aging.

As a matter of fact, you have UVB radiation and you have UVA radiation.

That's the one that damages your DNA and mostly causes skin cancer.

Well, our tanning booths are actually mostly UVA.

So, not only do they cause skin cancer, but they also accelerate aging rapidly.

So, that's why people that use tanning beds often look much older than their age.

And if there's one thing that I do on all my social media platforms, and when I get on here and I talk to all of you, is the worst thing you can do for your skin is go tanning.

Hujo PD asked, hey Siri, how do I get rid of genital warts?

Probably not tweeting to everybody about your genital warts would be a good start.

Genital warts are actually caused by the HPV or human papillomavirus.

And that human papillomavirus can cause cervical cancer in women and it can also cause penile cancer in men.

If you do have genital warts, that's something you want to get treated.

And it's also something that you don't want to spread to other people, especially your partner who could end up with cervical or penile or anal cancer as a result of that.

But once you have it, we do have several ways to get rid of it, including freezing them with liquid nitrogen and using other topical treatments like Imiquimod, which is a prescription medication and others that can get rid of them.

But I would have them treated and not try to spread them to other people.

But you have different types of HPV vaccines that are very effective at stopping you from getting this in the first place.

Now the HPV vaccine is approved up to 45, but it probably has even benefit beyond that.

There's actually a new study that showed that up to 87% reduction in cervical cancer in women.

So it actually makes a huge difference if you get it.

And I actually recommend it highly to people, especially at a young age to prevent getting HPV in the first place.

Next up, Dr. Che had asked, how the heck does Accutane work?

So Accutane is actually no longer on the market, but I actually use that word still myself.

So isotretinoin is a vitamin A derivative, but to understand how it works, we have to go back to what causes acne in the first place.

One, your skin cells basically stick together too much and basically clog your pores.

Two, you have bacteria that's stuck in those pores, clogging those pores.

Three, you have increased oil production that's trapped inside your pores.

And four, all of that bundle creates inflammation.

So basically four main things that causes acne.

Accutane or isotretinoin targets three out of those four very, very effectively.

It decreases oil production, decreases skin cell stickiness and decreases inflammation and is the number one best treatment for acne.

The problem is that it does have some side effects that we do need to monitor.

It's not the answer for everyone's acne, but for people with really bad nodulocystic or scarring acne, it is an absolute obliterating medication and life-changing medication for people that have acne.

Why does my skin break out when I have stress as if that won't stress me out more?

So when you have stress physiologically, it actually causes you to break out.

This is actually something that's really well-documented.

We have a hormone released from our hypothalamus called corticotropin-releasing hormone, and it actually acts on the sebaceous or sweat or oil glands within the hair follicles that actually causes acne.

So that stress hormone acts on your hair follicle to create the oil that causes acne.

You're stressed out more because now you have acne and it's just a vicious cycle.

And you can actually get in your own head and make your acne worse.

This is actually true for hair loss too, that stress can cause hair loss or telogen effluvium, and you can end up in this vicious cycle where your stress is actually making your hair loss worse.

I could just tell you, like, don't be stressed, but I'm stressed myself, so I don't really have a good answer for you.

But, you know, some meditation in the morning, you know, exercising can really get your mind off things, and just stick with a regimen that works for acne, and then that will help to improve it, but I can't eliminate all stress in life.

MiniPullyMe asked, while we're talking about stuff like this, is antiperspirant more dangerous than deodorant?

So good question, and a lot of people just consider these two to be the same thing, but they're actually very different.

So antiperspirants actually block eccrine sweat from happening.

The other side, you have deodorant, which actually doesn't do that.

It just is basically perfume, essentially, for your armpits.

Deodorants in general are gonna be considered to be safer, because there is some risk that people speak of regarding aluminum.

If you talk to most dermatologists and most people in the scientific space, they'll tell you that that risk is unfounded.

So there is some concern that aluminum can cause cancer.
