What kind of sunscreens are available and you totally got confused. What does it mean and What to look on if you buy a sunscreen and which one is actually best for you? So if one of the question is of interest of you you should definitely stick with me So Hi Guys My name is Dr. Liv Kraemer but everybody is calling me actually Dr Liv And I’m here in beautiful, Switzerland Actually beautiful Zurich. I’m a board certified dermatologist who doesn’t know me and I’m talking about all question I get from my Patients from you all the topic you interested in and I see that there are so many confusion all about some picking certain topics and I would be delighted if you give me some suggestions down there in the comments, so This topic today and by the way, subscribe to my youtube so share to your friends. Um and Now it’s all about Sunscreen what to do how to apply so let’s start. Okay, we talk about protection. We have to do it very systematically so let’s talk about SPF what does it mean? SPF means “Sun Protection Factor” sound’s actually cool So I’m just protect against the Sun as it’s higher than number as better…..Wrong….! Because guess what the numbers on a bottle of a sunscreen This one the number thirty fifteen fifty fifty plus is just referring towards UVB protection so now you’re getting confused as a like UVA, UVB what the difference of they’re all the same Oh, no, so let’s look at this Sun The Sun is a high-energy ray when I’d like the chemistry and chemistry lesson the Bunsen burner So you need energy to get something quicker done And the youth Sun is our Bunsen burner is the energy so you have UVA and UVB so UVB is a very low energy ray it gets reflected By the window, so now inside here. I’m not getting a sun burn I’m not getting a heavy cancer and not getting a tan because UVB is not penetrating through the window but Because we’re talking about beauty we’re talking about aging and anti-aging guess UVA is Penetrating the window. So UVA is a very rich energy goes through the window deep into the skin and smashing the cells exactly, and if the cells are smashed you get pigmentations rednesses and Winkles so now you’re also suffocate but if the SP and the number is just referring to UVB so it doesn’t really Matter it has something to do with history. It didn’t matter because we didn’t want to get burned So this is why we kind of choose numbers to have a referral things. So and the numbers as of that just referred to UVB so you have to look on a special label with a UVA Different countries different laws so here in Switzerland And in the European Union, we have a law that one-third of the actually number has to be a UVA protection So but in other countries it’s different. So it’s very important to look at labels so not just about that number but also about the label UVA with a round thing or in other countries about the PA+++ so something what is Protection or shows the protection against UVA. Remember UVA high-energy gets you the Pigmentations the redness and the wrinkles. Okay. So now we said okay we have to look at the labels We have to get to know that the numbers just refer to UVB But we want to make sure that we have an excellent protection factor or excellent protection against UVA as well So it has to be sign there Okay. Fantastic But now let’s go to the numbers which are very confusing for most of my patients and I guess also for you So the numbers I have a patients who said oh, I found an SPF 100.Now I’m safe That’s the best. I just got a couple of bottles now. It’s perfect…..Wrong. You are never safe So why I’m saying this it’s very easy. Let me show you something. It’s not…..it’s mathematic It’s about Science “Beauty is Science” And it’s not about linear curve So as higher the number as Better protection we have……no no no. No, it’s an exponential curve Now mathematics, this is why you have to stay in school and learn mathematics. That’s very important. So let me show you I hope you can see it. So you have a kind of a curve then SPF 30 is protecting you against 97% of the UVB but SPF 60 98 so funny right? It’s not like Double it’s all just 1% So the difference between 30 SPF 30 and 50 is just lower than 1%……Interesting? RIght?…..but we have to look an SPF act or at least with an SPF 30 because you know It’s big different above 50. Not really. So at least SPF 30 More than SPF 50,50+ doesn’t really matter so we also have to look at labels like UV a because we want to protect our skin against pigmentations redness and wrinkles So UVA is very important to look at the labels of UVA and now it’s a question about chemical and physical Filters, which I get asked a lot and people confuse to say. Oh, I don’t want to have Chemistry on my face. I don’t want chemical filters Okay Guys nature is physics and chemistry…….chemistry and physics is nature….Really Yeah, just don’t look like these buzzwords think before you say something. So nature is physics and chemistry without chemistry and Physics nature wouldn’t exist. So before you say something Think right. So let’s talk about physical and chemical Filters to really let you know what we are talking about if we say About these say something about this filters So if you know my videos but before about blackheads and whiteheads you know that a lot love to draw and all my patients of course know this so you have the Surface of the skin which looks indeed like a Cobblestone Wall…..mortar between the bricks bricks between the mortal So this is the Top layer. This is a lower part Physical filters are filters, which are just on top…..So you say…..Oh Great…! So they’re just staying on top…..Great….! but then you look totally whitish- because Titanium dioxide and Zinc Dioxide Are on the surface which of course is great, but let’s be practical most of you guys Complaining it looks whitish and look doesn’t look really great particular. If you have a darker skin type you really don’t like it So physical filters are great. But really not most of the time will be practical because They are whitish because they’re just reflectors. Of course, you can use tinted ones which a little bit better Which I’m kind of having a kind of the skin color of your skin type, but let’s go back to the physical filters to have a high energy the UV ray and they are hitting these reflectors and getting reflected This is how physical filters are working now Let’s talk about chemical filters chemical filters are filters who are are in the mortar between the bricks They don’t go through this stick here So and if you are a Serfer, you know what I’m talking about wave breakers, right? So and I think about your last Beach kind of holiday You don’t like these heavy waves. If you’re not a Surfer and just like to bath….like me….! So you Staying close to the beach because before you have these heavy stones which making them which reflecting the heavy waves into almost no waves we can bath and swim but so these wave breakers they Are Exactly the same as chemical filters Why because you have a very energy ray which are very harmful and these heavy rays are kind of hitting these Particles and getting transferred in low energy heat waves would not harmful anymore for your skin. So Ideally is having probably both on your sunscreen is the chemical filters and physical filter in combination to have the perfect protection against UV Rays, okay. So another question is we know about chemical and physical filters Now the question is what sunscreen I have to apply give me some tips Okay, So here are very useful tips if you have the tendency of pimples Acne, Redness, Rosacea never ever use creams Yeah….! But it’s Suncream….? It’s called Sunscreen But you have the possibility of the whole range from gel to heavy creams so if you don’t know what I mean look at my video about Serum creams which I give you a kind of thought. What is Difference but let’s be practical if it’s very sticky It’s not the right thing for you and believe me that couple of range of sunscreen available So look for gels like instead of very greasy creams So look rather also for a cream which is very light You see it’s always dropping and maybe has a little bit is a little bit tinted which is very easy to apply Doesn’t has greasiness. So I mean you could go for very sticky one and Have really problems applying it because it’s sticky and creamy…..Why going for creams if can look for Gel’s light ones without giving you the heaviness if you have the Problems with pimples and Acne. So another question. I always Get asked is about Sprays so sprays are actually not a good way Why because you think I spray once and then I’m protected guys It has to be 2 milligram (mg) per square centimeter. So to almost have the spoon so look for awful I have actually to pump and this is not even not for half of my face But so just spraying ones you never get the SPF Factor, which is on the bottle so the SPF factors on the labels are just referring to an Amount of sunscreen. We’re applying on your skin. So for example a makeup it was an SPF So first of all an SPF of 15 on a makeup is not enough secondly, there is no UVA protection side so you still aging and You never apply this thickness of makeup that you’re really getting the SPF factor Which is on the bottle of your make a powder of make up ground or whatever so therefore Really….! Make sure you wash your face you put maybe a very light serum with Antioxidants on side not crazy not oily very light if you have the tendency to pimples Acne or Rosacea And then apply your sunscreen in a real amount. What does it mean? Really? If you really want to protect yourself you have to apply three kind of almost two fingers for your whole Face Yes, it’s a lot. So if you’re putting it on, you really have to massage it in like a primer using Makeup the same as you have to do with the sunscreen were really massaging it in really deep Look at my video how to apply sunscreen. So let’s summarize to get the confusion out now So first of all Look and SPF factors the numbers at least 30 below doesn’t really matter 50 is totally enough everything above 50 is misleading Look at lables like UVA or PAA+++ as high as better because you want to protect you face against the harmful UVA lights, which are giving you Pigmentations Rednesses and Collagen loss namely Winkles Try to apply a really good amount on your skin and Do it after washing in the morning after applying anti-oxidant serum and if you had Acne, Pimples or Rosacea Then just light serum and then a light sunscreen in a kind of a gel Or lotion not in a sticky cream if you want to reapply sunscreen, of course, it’s great But if you applying makeup, it’s probably impossible We apply then a spray might be a possibility but it really doesn’t give you the amount What it says on the bottle because the amount you have to apply is so it is so much more that you think you have To really pump almost 10 times and put it on to really get you the SPF protection Which is on the bottle…! Ideally what I also like to show my patients are sticks, so SPF sticks 50 Some sticks are not whitish at all, but there are very fatty but it’s nice to apply it around the eyes During the day have this in your pocket and just reapplying it under nose on the cheeks and maybe your all around also On top of the lips, but be very careful because these sticks are very sticky very fatty So, if you are applying it somewhere, where you have the tenancy of Acne, know you are actually getting more pimples So really maybe just stick around the eyes because these are the Sun terraces so this is where the Sun is hitting and where you have to protect a very Intense your skin. I will talk another time about this.
