Summer Skincare with the Mayo Clinic and Dr. Alison Bruce | River City Live

welcome back the Sun is getting stronger the temps are getting hotter so how do you protect your skin today we have dr. Allison Bruce with the mayo clinic here at dermatologist to really help us out so welcome to River City live it’s great to have you you think and we have a lot of questions especially when it comes to sunblock so let’s start there a lot of parents out there grandparents they want to protect their kids they want to protect themselves so what should we be looking for what type of active ingredients when it comes to sunblock okay well I think that this is a great time to be asking this question with Memorial weekend coming up everybody’s going to be out in the Sun and Mark I’m going to take the liberty of making a plug for something to remember and that is it’s not all about sunscreen there are other ways that we can protect ourselves from the Sun so like animals do seek the shade lie under trees you know animals know interiors of liter hunter early in the day and like late in the evening so remember that you know seek shade the other thing protective clothing is very important and then sunscreen is kind of part of that so I know you wanted to are specifically about that and there are some important things to look for in sunscreens sunscreens really work in two ways they can have what we call physical blockers in them or chemical blockers and if you think about a physical blocker those are usually your ingredients like zinc oxide or titanium dioxide and that is like a shield that sits on the surface of the skin and it basically prevents the Sun from getting to the skin and deflects the Rays off and those are very safe sunscreens we recommend them for children we recommend them for people who’ve got very sensitive skin so those are your physical blockers and then you also get chemical blockers which are compounds that actually absorb the energy of the Sun and prevent it from getting into the skin it converts it into heat so that the energy of the Sun doesn’t damage the skin so and the chemical sunscreens I think you may have heard a little bit about some of the controversy related to that and just recently on that exactly exactly and the debate about that is whether some of those chemicals may be absorbed into the system because there were some studies recently that showed that that might be happening the Christian eye however is to what extent are they being absorbed and is it of any impact because just because it’s absorbed doesn’t necessarily mean it’s dangerous sure and going back to our points earlier on sunscreen is a very important part of protecting our skin because skin cancer is so common it’s actually the most common cancer in the u.s. is skin cancer one in five people develop skin cancer in the course of their lifetime now what about the number when it’s on the bottle because obviously it goes anywhere from 15 all the way up to a hundred does it mean anything because I learned that actually after fifty it’s no longer more effective at that right exactly so you’ve learnt the right information that is correct yes so basically what happens if you think of it like a curve in terms of your it’s what’s called what’s called an SPF and the SPF is simply the amount of protection against UVB and UVB is the part of the sun’s radiation that causes the skin to burn so if you think of it like a curve when you start at zero that as that SPF goes up it gets really effective around fifteen or thirty and then it kind of levels off so there’s not much difference between a 50 and a sixty and a hundred same now what about waterproof is there such a thing when it comes to sunblock very good question because obviously people want to protect their children as much as possible and children spend a lot of time in the water there is no such thing as a waterproof sunscreen and it’s actually now the FDA has made it illegal to put waterproof on a sunscreen so just to give you an example this is a very out-of-date sunscreen but it actually says on here waterproof and sweat proof and so the sunscreen is out of date that’s no longer legal to do that but sunscreens can be what we call water resistant so for example if you look at one like this and this has that SPF that we’re looking for SPF 441 so it’s above our 30 it is a physical sunscreen meaning this is going to be a zinc oxide sunscreen it doesn’t have any of the chemicals in it but it has the words here water resistant meaning it will protect you for up to 40 minutes Wow which is not very long if you think about it that’s less than an hour but it’s still so you know every 40 minutes you put it on and it’s got the active ingredients that you need on there exactly exactly you know unfortunately we’re running out of time because the next thing I wanted to talk about is if you do damage your skin what can you do but obviously over at your clinic you have so many different treatments that you could do and maybe at a later date to come back on and talk about that we also have a promotion right now for our viewer’s so basically it’s the Mayo Clinic signature facial you get 15% off just mentioned River City live the number right there two calls nine oh four nine five three zero seven nine five dr. Bruce thank you so much for all your time and information like I said I definitely like to get you back on to talk about the clinical side and what we could do if we did damage your skin sounds like a plan like a plan thank you thank you so much stick around more to come
