00:00Sunspots, dark spots, fine lines, wrinkles.
00:04If you want to stay snatched,
00:07you need to be doing something
00:08about your sun protective measures.
00:11♪♪
00:14Hello. I'm Dr. Angelo Landrocena,
00:17and I'm a board-certified dermatologist.
00:20Looking for medical information online
00:22could be unreliable or anxiety-provoking,
00:26so today I'm going to be answering
00:29some of the questions that might be
00:31getting under your skin.
00:32Can retinol be used on the body?
00:35The answer is absolutely.
00:37They could be used for some of the same concerns
00:39that you would use retinol on the face for.
00:41Some of the signs that go along with photoaging
00:44think discoloration, maybe rough, bumpy skin.
00:48In addition to that, there are prescription retinoids
00:51that are specifically indicated for use on the body.
00:54Usually those will be used for acne.
00:56The difference between a face retinol
00:58and a body retinol product
01:00is generally the concentration of retinol used.
01:03It's likely to be lower in a body retinol product
01:07just because you're covering a larger surface area.
01:10Also, the vehicle in which the retinol is dispersed
01:13is likely to be different.
01:15Our body skin tends to be quite thick and robust
01:20compared to facial skin,
01:21so it's going to need a different type of vehicle
01:23to have the best result.
01:25Can eating dairy products make you break out?
01:29The answer is kind of a big maybe.
01:31I think a lot of the interest in this topic
01:34has come from some of that standard classic advice
01:39that a lot of us got as teenagers.
01:41Oh, if you eat better, if you drink more water,
01:44if you do this or that, your skin will clear up.
01:46And I would like to say that in most cases,
01:49those people were wrong.
01:51A lot of this comes from an idea
01:53specifically about acne in general,
01:56that it is a personal failing
01:59that needs to be blamed on the person suffering with it
02:02when really it's a chronic inflammatory skin condition.
02:06It's a medical condition,
02:07and it should be taken seriously.
02:10Not only because it could cause physical scars,
02:13but also because we know that people with acne
02:17suffer higher rates of mental health disorders
02:21and even things like suicidal thoughts.
02:23There has been quite a bit of interest
02:26about the correlation between diet and acne
02:29within the dermatology community too.
02:31And there have been a lot of studies about it.
02:34There have been correlations
02:36between eating high amounts of dairy products,
02:39eating certain dairy products, and more severe acne.
02:43However, there's been a lot of variation
02:46and a lot of gaps in the data.
02:49So a lot of these studies can only be generalized
02:53to certain age groups or certain parts of the world,
02:57certain diets.
02:59Breaking it down in a nutshell,
03:01I do think that for some people,
03:03certain dairy products could cause a worsening of acne.
03:07However, I think it's a very unlikely
03:10that for most people that dairy products
03:13or other features of their diet
03:15could be giving them acne.
03:18I always say it's never too late to start,
03:20you know, start being consistent
03:22and really paying attention to what your skin needs.
03:24For most people, your skin's not gonna need that much.
03:27A basic skincare routine should consist of a cleanser,
03:31a moisturizer, and a sunscreen.
03:35Each of those is gonna play an important role
03:38in keeping the skin healthy.
03:39The cleanser, that's going to prep your skin,
03:42remove any debris from the day, remove makeup.
03:47If you're a makeup wearer,
03:49really just set you up with a clean canvas.
03:52The moisturizer to really aid your skin's barrier.
03:56One of the primary functions of our skin
03:59is to keep what's inside in and to keep what's outside out.
04:02And one of those substances
04:04that it's trying to keep in is water.
04:06So using a good moisturizer
04:08is going to help keep your skin hydrated,
04:10healthy, glowing,
04:12and then perhaps most importantly, sunscreen.
04:16UV exposure is the primary modifiable risk factor
04:21when it comes to skin cancer for most people.
04:25Using sun protective methods that include sunscreen,
04:29protective clothing, seeking shade,
04:32all of those things is gonna be really important
04:34for keeping your skin healthy.
04:36In addition to that, you know,
04:37I am in the business of appealing to people's vanity too.
04:41So it will keep you looking younger for longer.
04:43It's gonna prevent or help to treat
04:45some of those sunspots, dark spots, fine lines, wrinkles.
04:50It's also implicated in like the loss
04:53of firmness in the skin.
04:55So, you know, if you wanna stay snatched,
04:59you need to be doing something
05:00about your sun protective measures.
05:03When it comes to the basics between age groups,
05:06say 30s, 40s, 50s, 60s, beyond,
05:10there's not really gonna be much of a difference
05:12in the product profile that you're gonna need
05:15in your basic skincare routine.
05:17However, there might be slight tweaks.
05:19For instance, as we get older,
05:23we do have differences in how dry our skin is.
05:26Skin tends to get drier as we age.
05:29So you may wanna go for a thicker moisturizer
05:32or a gentler cleanser than you would when you were younger.
05:36Once you have the basics of a skincare routine down,
05:40you could definitely look at adding more products
05:43based on what your specific concerns are.
05:47I'm a big proponent of what I call intentional skincare.
05:52So I always tell people, including my patients,
05:55don't just buy a new flashy product
05:58because it looks nice,
06:00or your friend told you it was great,
06:02or the marketing got you.
06:05Really look at your skin, take an inventory
06:08and see what about it you wanna address,
06:10whether it be something like dark spots,
06:13acne, fine lines.
06:15You're gonna wanna look for the product
06:17that will address your specific concerns.
06:21Oh, I love this question.
06:24Is there a difference between a sunscreen
06:28and a moisturizer with SPF?
06:30Not really.
06:31To me, most of it is marketing.
06:33A lot of the ingredient profile
06:35in the sunscreens that are out on the market
06:38and moisturizers are really similar.
06:41The only thing that I would caution people about
06:44is the fact that that SPF rating
06:47is based on using a certain amount of the product.
06:52So if you're using a pea size of that moisturizer with SPF,
06:56that's not enough.
06:56You're not going to be getting the SPF listed on the label.
07:00I know for most people,
07:02it's gonna be hard to have an exact science
07:04for knowing how much of each product to apply.
07:08So what I tell people for facial sunscreen
07:12is you could follow the,
07:13what we call the three finger rule,
07:15doing a line of sunscreen down each of your three fingers
07:21and that's how much you should apply
07:22for the face, neck and ears.
07:23If you wanna keep it simple,
07:25just use more than you think.
07:27It's really a lot more than people would think.
07:30And I really feel like most of the population
07:33is under applying sunscreen.
07:35Do collagen supplements actually work?
07:38You may see a whole slew of collagen pills,
07:41powders, shakes, et cetera, out there on the market.
07:45And a lot of experts would say
07:47that these aren't gonna do anything.
07:49Just based on logic, collagen is a protein,
07:54which means it is a long strand of different compounds.
08:00When we take protein into our gut,
08:02it gets digested by the acid in our stomach and by enzymes.
08:06So you would think that ingesting collagen
08:09wouldn't do anything, but there is some data out there
08:13showing that it actually may make a difference for skin.
08:16First, there are animal studies that do show
08:19that collagen induced orally does make it
08:23to the skin as collagen.
08:27We're not really sure if that happens in humans,
08:30but it does give us a little bit of hope.
08:34In addition to that, there have been some studies
08:36showing improvements in things like skin hydration
08:41for people who are on collagen supplements.
08:43Is it a gold standard treatment for anything?
08:48No, I definitely think we need more data
08:51before we could be really prescriptive
08:52with collagen supplements.
08:54But at the same time, it doesn't seem like it'll hurt.
08:58So when should you start Botox
09:00if it's something that you wanna pursue?
09:03I think it's hard to put an exact age on when to start.
09:07What Botox is is a neuromodulator.
09:11And what that means is that it cuts off
09:14some of the crosstalk between nerve and muscle
09:17and causes a temporary paresis in facial muscles.
09:22The reason you wanna do that
09:24is to prevent or treat expression lines.
09:27Those are lines that come up on the face
09:29from repetitive facial movements.
09:33Things like raising our eyebrows,
09:35grimacing, smiling with our eyes.
09:39For most people, I think it's okay to start Botox
09:43when you're starting to see those lines come up.
09:46If you're in your 20s and you have those lines already,
09:49you could be a good candidate
09:51if it's something that you want.
09:52If you're in your 60s and you don't have those lines,
09:56it may not be something that you need.
09:58There's been a lot of interest recently
10:01in preventative Botox.
10:03So using smaller doses in people who don't have lines yet
10:08in order to prevent them from coming up.
10:10When it comes to whether or not that's a valid approach,
10:15by logic, it would make sense that it would work.
10:19However, we have no scientific data
10:21showing that preventative Botox actually does anything.
10:25I hope this has been helpful.
10:28However, keep in mind, everybody's different.
10:30So make sure to check with your own doctor,
10:34who knows you, before making any changes.
10:37You can find me on all social media at Dermangelo.
