Hướng dẫn đọc hiểu KEM CHỐNG NẮNG ❌ Đừng tin bừa chọn đại‼️| Skincare Class #36

Hello comrades Our bureau has an urgent meeting today Have any of you noticed anything unusual lately You look especially beautiful today That's exactly right isn't it You all truly have sharp eyes But what I'm referring to here is the online community's reaction Lately the internet has been buzzing It's because summer heat is upon us It's very difficult to find suitable sunscreen Moreover recent information has further confused public opinion While our agency's mission is to They had to ensure each user could choose the sunscreen best suited to their needs So do any of you have suggestions I have an idea What do people think about UV Cam I disagree UV Cam itself has generated a lot of controversial opinions Not to mention the high cost there are many opinions that UV Cam merely indicates the presence of chemical sunscreen ingredients That means it's absorbed into the skin only Any components remaining on the skin's surface won't be visible under UV light Or let's just do a review Let's dive right in with a full review Review every single sunscreen we have But we can't possibly review every sunscreen on the market Not to mention no sunscreen works for everyone Therefore I suggest we help each person gain the ability to independently understand sunscreen information and proactively seek out products that suit their needs The review is merely for reference That's a tough solution since there's no guarantee people will be willing to listen or take the time to understand But it's definitely worth trying The green comrades had no objections So we've reached a consensus Alright comrades Let's see if I choose wisely I'll succeed Excuse me comrades may I be allowed to speak first Hey take off your shirt smoke Tell the sunscreen we must begin with the matter of How sunscreen is classified In the past we classified sunscreens based on their mechanism of action Specifically sunscreen will be divided into three types: physical sunscreen chemical sunscreen and physical sunscreen chemical sunscreen According to this method anything that reflects UV rays Then we call it physics What absorbs and neutralizes ultraviolet radiation in the skin is called chemistry And something that both reflects and absorbs is what we call a hybrid sunscreen However this classification faces numerous challenges Differing opinions exist First of all it is claimed that physical sunscreen itself contains ingredients such as titanium dioxide zinc oxide primarily reflects UV rays but also absorbs and neutralizes a small portion of them So it's not entirely about the physical aspect either Then alongside that there are also differing opinions regarding wordplay Titanium is titanium or if it's cream it's also in the periodic table of chemistry Why is it called physics To avoid all possible misunderstandings and as for the unnecessary debates we 'll address them later by introducing a different classification system that sounds more appealing and friendly with a more environmentally friendly approach These are mineral sunscreens organic sunscreens and hybrid mineral-organic sunscreens Within these categories Organic sunscreens are sunscreens whose active ingredients contain carbon atoms For example: Avobenzone Autocrylene Dinosaur S Dinosaur M Then sunscreens that contain no carbon-based molecules are called mineral sunscreens For example Zinc Oxide and Titanium Dioxide contain only metal and oxygen They consist of just these two elements Then we'll refer to it as hybrid sunscreen Now let's agree on calling it this way and move forward together comrades Thank you Director and I'd like to follow up on your remarks to explain the symbols found on sunscreen products that we need to understand First that is the SPS symbol when discussing SPS we know it indicates resistance to UVB rays also known as UV burning at is the UV filter causing sunburn leading to skin darkening and skin burns on our skin And for example if SPF 30 en we understand that it protects our skin from 96.7% of UV rays and does so over a period of time 300 minutes equals 5 hours If SPS 50 it means the skin is protected by 98% and within Five hundred minutes roughly speaking is about eight hours but in reality it's not nearly as perfect or flawless as that might suggest Sounds incredibly ideal but there are numerous issues comrades need to pay close attention to First this result is from a validation test the laboratory under impossibly ideal conditions and using sufficient quantities—this is why we can' t be certain we've achieved it This level of protection is exactly what we actually use The second point is that although it sounds like 98% Within eight hours right But it's not about the very first minute by the final minutes they'll be the same but in reality our skin's ability to protect against UV exposure gradually declines over time much like a steep decline For example If SPS is 50 within the first 10 minutes we'll be protected 98% meaning there's only a 2% chance of getting burned out Alright but after 30 minutes it was already 6% and after 150 minutes it had risen to 30% This means we shouldn't rely solely on the SPS rating printed on the packaging The first is that we must use sufficient amounts and the second is to extremely limit exposure to the sun for extended periods especially during peak sunlight hours sunlight can destabilize certain sunscreen ingredients which is why it's important to apply sunscreen carefully called downgrading Or when we sweat and then apply oil it further reduces the sunscreen's effectiveness Another symbol that may or may not appear on the packaging is PA or in some places PPD persistent pigment darkening According to what we understand PA or PPD indicates the skin's protection level against UVA rays UVA UV aging also known as UV aging is the primary cause of premature aging resulting in wrinkles and sagging skin and along with UVB exposure also causes other conditions such as melasma hyperpigmentation or skin cancer I've already said this many times before comrades What I truly want to emphasize with you today is really The point is PA 3 plus PA 4 should be understood as equivalent to the entire PPD at's about 8 to 16 meaning protection against UVA rays equivalent to 8 to 16 times better than without protection We don't use sunscreen And if it's PA 4 plus as indicated on this packaging that means it's equivalent to with SPF 16 or higher means it will protect our skin up to 16 times or even 32 times better 46 times greater than not using sunscreen saying it that way means the higher the PA or PPD rating the better Is that right Yes but everything comes with its price comrades If we want high PA or PPD then Sometimes we just have to accept that the product will be slightly oily as the ingredients that offer the best protection against UVA are often this way Since it dissolves in oil we also need plenty of oil or certain condiments to help dissolve these active compounds The second point is and if we want to protect effectively we also need to use a supplement with a high concentration of these substances and the higher the better The higher the level the greater the likelihood of irritation therefore for PA a score of 4 could be equivalent to 16 or even 32 or is it 46 right Well anyway adding 4 is fine too and if the packaging says PPD en just look for anything from 16 and above—20 to 40 is perfect broad spectrum wide-range sun protectio refers to sunscreens being able to protect the skin from UVB UVA2 and UVA1 rays however comrades must keep in mind remain cautious because many sunscreens labeled as broad spectrum on the packaging may not actually provide comprehensive protection and it's unclear just how extensive that coverage truly is Not necessarily because just resisting a small amount of UVA1 exposure is enough to claim broad-spectrum protection So How widespread it truly is can only be verified by our ability to comprehend the inner components or the Behind the packaging Very high protection a phrase commonly found on sunscreen labels from Océan equivalent to the following very high protection equivalent to SPF 50+ high protection SPF 30–50 medium protection SPF 15–25 low protection SPF 4–10 owever it's important to note that very high protection does not imply high UVA protection so very high protection is not necessarily guaranteed It's perfect comrades this is the rating indicating the sunscreen's water resistance allowed to be displayed on packaging from 40 to 80 minutes although no sunscreen is truly waterproof or sweatproof so even the FDA of the United States and the standards for screws no longer permit the use of the terms waterproof or sweatproof but only water resistant In practice the product is colored and typically serves to even out skin tone as well as provide light coverage Honestly comrades back then I wasn't really fond of using authentic products because they were usually Darker than my own skin tone but recently there have been many new sunscreens available lightly tinted In this way the vibrant colors are very suitable however if comrades are not interested in purchasing products with moon motifs or bright colors When there's coverage it's best to pay close attention to avoid mistakes but there are also cases like this one where nothing is written on it If you're buying packaging then we must carefully check reviews before purchasing especially for oil-free anti-shine or matte options ey are products designed to address oily skin without leaving a greasy shine in terms of ingredients these Oil free products ypically products that are not oil -based formulations some products that do not contain mineral oil may still claim to be oil-free However it's also possible that in the ingredient list we might still see some entries labeled as natural oil or fragrance oils and products such as oil-free anti- shine matte truly achieve this because their ingredient lists contain specific compounds that help control shine but could also be oil-absorbing or oil- saving such as silicon or aluminum starch or even alcohol which is the pillar regarding Comrade Hong's turn I would like to present some important active ingredients but we must remember Of course comrades can explore additional active ingredients by clicking the link below but what I shared below in the description the goal However here it only briefly touches on a few points The golden faces in the heart of the sun's rays are just that—sunlight itself But before that we need to review a little knowledge about the different types of UV rays cludes UVB with wavelengths from 280–320 and UVA2 from 320–340 UVA1 The shorter the wavelength the higher the energy and greater the destructive power waves with lower energy however penetrate deeper into the skin and may cause damage to the dermis also known as the corium I would like to divide these into three groups of components First that's the broad-spectrum sun protection group meaning it shields against both UVA and UVB rays And the recent light source we often hear about this being Trinusoft S and Trinusoft M let's start with Trinusoft S as it is the component with broad-spectrum protection ranging from 280 to 400 with the best protection occurring at two wavelengths 310 and 345 The mechanism works both as a UV- blocking filter and as an absorber and neutralizer of UV radiation making it a comprehensive protective filter Extremely effective and safe it stabilizes enzyme-rich areas while enhancing the skin's protective capabilities in delicate sunscreen formulations Honestly even though it's a budget product knowing it has Trinusoft S or M makes me feel much more confident Tell another brother that Trinusoft M also has a protection range from 280 to 400 but there's a difference First the best protection is at a wavelength of 306 with fairly good protection also at a wavelength of 305 but not as good And when comparing Trinusoft S with Trinusoft M we see that the protection range of Trinusoft M extremely wide even capable of shielding against blue light meaning wavelengths beyond 400nm However When it comes to strong protection Trinusoft S clearly stands out doesn't it It's truly in a league of its own Down it goes all at once— for Trinusoft M there's a steady stability across each wave so when it's combined it's consistently reliable Between these two components it' s absolutely perfect—Missoring XL also known in the ingredient list as Dermatrizone Trisilocane is this a component developed using L'Oréal's patents commonly found in sun protection products All of the company's brands including Garnier L' Oréal Paris and La Roche- Posay feature Missoring XL and this is a broad- spectrum sunscreen covering from 280 nm to 390 nm with peak protection a at 300 nm and 340 nm This is a component that is oil-soluble so if it is When used at a higher concentration it becomes slightly glossy The next ingredient is Zinc Oxide is very common and also a broad-spectrum sunscreen ingredient effective from 280nm to 400nm where Peak Protection is 370nm However if you look at this chart comparing the substance I just introduced to you en you'll realize that zinc oxide is actually a broad-spectrum sunscreen but it's not particularly effective The issue is tha used in high amounts One more thing to note when using Zinc Oxide is that this ingredient is insoluble in both oil and water so it will create a certain opacity white on our skin when applied and truly the more Zinc Oxide there is the whiter this appears—wait let me continue— Let's go ahead and plot this chart once more comrades Take a look at this chart The key takeaway is this Nothing in this world is perfect The task of those formulating sunscreen was to combine ingredients that complement each other's weaknesses for each other For example there might be some sunscreen blends combining China Soft S with China Soft M like the one I had that day at that time Or some other sun protection components would have Missoring XL However Missoring XL although widely used but the effectiveness isn't particularly outstanding So what else should be combined China Soft S is very powerful in protecting against UVB and UVA 1 Then there's Avobenzone extremely effective at protecting against UVA plus added stability That gives us a formula that could fairly be called perfect—when discussing a standout ingredient in sun protection one cannot fail to mention UVA defense Avobenzone is an excellent UVA protective ingredient with a range from 310 to 400 peaking at 357 To this day avobenzone remains a classic ingredient and is still widely used in numerous products The only issue is that every time I use it I experience erectile dysfunction because the UV isn't stable and loses effectiveness very quickly As a result many products have combined Avobenzone with China Soft for example and another commonly used ingredient in UVA protection is en we must mention UV Neon A Plus which has a range from 320 to 400 with a peak at 354 quite similar to both Avobenzone slightly less effective but more flexible can be used at higher concentrations and is more stable Compared to Avobenzone the leading UVB blocker I’d like to recommend only one: UV Neon T150 In fact there are numerous other effective ingredients available can block UVB Back then it was always talking about sand Bioshock oxybenzone octocrylene Optimus X blah But those components each have their own unique features and characteristics whereas UV Neon T150 is quite perfect can resist UV range from 290 to 340 with a peak at 314 offering extremely strong protection against UVB and is water-soluble Because it's oil-based it's commonly used in water-resistant sunscreen products Besides sunscreen agents I recommend that everyone Look for its close friends in the sunscreen's formula— gentle soothing ingredients like B5 aloe vera and others Lysinamide helps prevent Kim family's contamination from causing hyperpigmentation or acts as antioxidants to repair cells because These antioxidants not only neutralize free radicals generated by UV exposure but also appear to offer superior protection for the skin before any other expenses including the cost of funeral rites Thank you Comrade Green for your very thoughtful and insightful remarks now the floor is mine and I will proceed with my presentation All comrades have two sunscreen products from two different schools The first product belonging to the My partner never smiles but he's really kind—my partner feels sorry about it For many people this might just be a sunscreen product Perfect but the one flaw—just one—is that it's not meant to be used on the face and the dragon's wok Product two imperfect yet endearing in its own way This is the product that if the book were about ingredients It's not overly intense but it creates a wonderful effect on the skin and feels like something you could use daily Now let's break it down for everyone: this product has an SPF of 50 and a PPD of 33 —sounds impressive doesn't it Compared to the sunscreen ingredients it will use octinoxate Tinosorb S Tinosorb N and avobenzone—plus many others in the formulation pure ingredients that restore hydration to the skin at the corner of the street including Manitone Silitone Rhamnose and Fructooligosaccharide Absolutely amazing And here's my take Even if it's not perfect what does this one offer SPF 50 PA +++ — look at this It feels a bit weak around TUV protection Specifically if talking about sunscreen ingredients there's Zingocide Titanium Dioxide Octinoside Octisalate primarily focuses on blocking UVB so it's very common and since it only slightly darkens the skin when applied Just slightly light not overly white so I'm making a guess that Zingocide is definitely under 10% and clearly shows opposition Resisting TUVA is only allowed as three plus signs not four plus signs In addition she further added some anti- components moisturizing and antioxidant properties include vitamin E Coenzyme 10 and hydrolyzed collagen to hydrate the skin Another ingredient is Acetylhexamethate 8 is highly renowned for its ability to combat aging and tighten and smooth the skin But when placed toward the end of this ingredient list it's likely its primary function is more moisturizing than anything else Thank you to our comrades for your heartfelt dedication now that we' ve thoroughly understood let's earnestly carry out the implementation Fast and powerful on a broad scale—now comrades watching this video clip—comrades are the seeds the core backbone of this work So sincerely I hope that after
