There are hundreds of videos of guys unloading an Airsoft gun on bare skin. The one thing that usually accompanies these videos are funny moments…

It does penetrate the skin and it hurts.. Although getting hit hard enough by a BB that penetrates the skin does sting, it’s not enough to take you to a hospital.. When an Airsoft gun is shot from a close distance and with enough velocity, it will penetrate the skin.. Getting hit on a sensitive part like the throat might cause injury but not due to the BB penetrating the skin.. You generally don’t expect to bleed from an Airsoft BB penetrating the skin.. Ensure that you play in fields that have strict rules on fps limits.. Airsoft BBs hurt when you’re not properly protected.. Wear something that gives more padding to reduce the impact of the shot and prevent any serious damage.. Most airsoft players and organizers will recommend using a pair of goggles as well.

It is often asked do cosmetic ingredients penetrate the skin or is it just a marketing ploy to get you to spend more money. Simplifying the truth

If they do penetrate, am I going to get the benefits that the scientist in the laboratory get in their studies.. In this blog we look at the conditions that need to be present for an ingredient to penetrate into the skin to deliver the benefits of healthy glowing skin.. There are many companies and products to taut the benefits of their products and of the active ingredients.. There are 3 physical routes in which ingredients can penetrate is Epidermis.. Water molecules are too large to be absorbed into the skin.. As pointed out in the above criteria our skin does not allow for water to be absorbed into the skin therefore in general, oil soluble ingredients penetrate the skin far more easier than water-soluble ingredients.. As the lipid (oil) that fills the space between the cells of the epidermis is an oily substance and thus it will be attracted to lipophilic ingredients and reject the hydrophilic ingredients.. As a cosmetic chemist it does play an important role in formulating a product and how well an active ingredient will be absorbed and used by the skin cells.. Normal skin Acid mantel has a pH of 4.5 to 5.5 but when it is outside this range it can cause many skin problems and irritations but it will also affect the skin ability to absorb normal active ingredients.. So if you have an active ingredient that is small enough, at the correct polarity, etc as discussed above it needs to be in the correct formula to enable the ingredient to be delivered.. The product can also use of other ingredients in the skincare product that enhance the ability of skin penetration.. For example a water soluble (hydrophilic) vitamin is encapsulated in an oil (avocado oil derivative) that allows the vitamin that would normal not be able to penetrate the epidermis to penetrate and be delivered to the cells that need the vitamin.. Two great natural penetration enhancers is jojoba oil and peppermint oil.. All products, material and information provided within this Website are for educational and informational purposes only.

Please support the Beauty Brains by signing up for a free audio book at Click here to get your free audio book. Chris says…Can you guys talk a little bit about ingredient penetration? Why do some ingredients penetrate skin while others won’t? What mechanisms and conditions are involved? Let’s start o

How skin penetration works The 4 main factors that control skin penetration And perhaps the most relevant question – is penetration necessarily a bad thing.. Epidermis. “Epi” is a Greek term is used as a prefix meaning upon or or above so the epi-dermis is the layer that’s upon or above the dermis.. So this is where we start our discussion of skin penetration because to get into the skin the first thing an ingredient has to do is find its way in between those layers of brick and mortar.. Most molecules are simply too large to slip between those cracks between the “bricks” of the dead skin cells.. Its also important to realize that the risk of an ingredient penetrating skin is is factored into the safety assessment done on cosmetic ingredients.

In order for skincare products to work effectively they must penetrate the skin properly. To find out whether or not an ingredient does or does not penetrate the  skin we should talk about:

The skin is made up of different cell layers designed in a brick and mortar pattern and each layer is a collection of:. Function: “The granules of this layer contain lipids and break open to release their contents into the space between the cells in the stratum lucidum and stratum corneum layers.. Skincare for this layer: Overuse of hydroxy acids, retinoids, and other exfoliating ingredients can damage this important layer.. Made of: – Keratinocyte – Desmosomes: interlock with each other and strengthen the bond between the cells prevent your skin from tearing and blistering.– Langerhans cell: is a type of dendritic cell which functions by washes off bacteria, foreign particles, and damaged cells that occur in this layer.. Keratin is what forms the rigidity of your skin and is why skin is waterproof.– Melanocytes: responsible for producing the skin pigment, melanin.– Merkel cells: function in the sensation of touch. Main function: All of the keratinocytes are produced from this layer responsible for making melanin which gives skin its color. Because this layer is the innermost layer, many topical products that you apply to the surface of your skin cannot reach this layer and have an effect.. That is why applying stem cells to your skin’s surface is a waste of time – the uppermost layers of the skin prevent large compounds like stem cells from reaching this deep layer. Dermis is made of: – Fibroblasts: are the cells which synthesize collagen and elastin– Collagen: is a long-chain amino acid making up 75% of the skin.. Over the years various skincare products/ treatments have been developed to target different layers of the skin to help the skin repair itself and prevent aging.. Example of the molecular weight of common skincare ingredients:Water: 18 DaltonGlycerin: 92.09 DaltonMatrixyl: 578 DaltonHigh molecular weight Hyaluronic Acid = 1.0 – 1.5 Million DaltonsUltra Low Molecular weight Hyaluronic Acid = 6000 DaltonsLactic Acid: 90 DaltonGlycolic Acid: 76 DaltonsSalicylic Acid: 138 DaltonsL Ascorbic Acid: 176 DaltonRetinol: 286 DaltonRetinal: 284.44 DaltonRetinoic Acid: 300.44 DaltonPhenoxyethanol (preservative): 138.16 Dalton. The reason that some people see good results using topical products which contain collagen is that the large molecule stays on the surface of the skin and prevent moisture loss, so the skin is kept hydrated and hydrated skin is plumper!dah!. Are molecules Oil-soluble or water-solubleOil soluble ingredients have the ability to slip through the bricks of the skin while water-soluble ingredients only work on the surface of the skin.. In-office treatments: Some procedures such as microneedling and laser treatments create small abrasions on the skin, which makes it possible for some skincare ingredients to penetrate the skin.. ** Penetration means that the ingredient goes further into the layers of the skin, while absorption means that the ingredients make it all the way into your bloodstream.

I was wondering if any values for this were ever recorded. How strong is human skin when subjected to pressure? Since there are figures for steel which constitutes classical armor and values for bullet proof vests, I wanted to work out what magnitude of protection those things give you against...

Well, the surface area is what creates pressure.. Well, the surface area is what creates pressure.. Mass, surface area, material, velocity, region of the body, variations in density of the dermis... it's too still too variable.. Well, the surface area is what creates pressure.. Mass, surface area, material, velocity.. But these variables all come back to varying the pressure, when the question is really about how much pressure the skin can take.. A faster needle, knife, bullet will exert more pressure at its contact surface, than a slower version of the same mass and contact area.But these variables all come back to varying the pressure, when the question is really about how much pressure the skin can take.. In practice, I'm sure that every region has a specific psi for a given time of day, and person, but if you're interested in ballistic armor here is the difference: A 130 grain bullet traveling at 1400 fps is going to be exerting orders of pressure above what is needed to penetrate skin.. This also goes back to material, which isn't an issue if we're talking about shrapnel and bullets.. As for the 100psi figure, if we're not talking about specific material, location, and more, it's a meaningless figure.. I was surprised- I couldn't find any measured data.. I was surprised- I couldn't find any measured data.. Re: What pressure is required to pierce human skin:I am researching this subject also but my perameters are more specific.. 2. can someone provide the thickness of the top layer of skin that will resist the penetrating force.. From their figures for force and needle diameter (their needles are practically just little cylinders) I get between 7 and 37 MPa as the figure for "ultimate yield strength vs penetration".

As I mentioned in my post last week, molecules don't penetrate or absorb the skin as easily as one would think. Consumers these days are a lot more conscious about what they put on their skin and are definitely a lot more skeptical.  'Can this cream really get rid of my wrinkles? Can it r

In the intracellular route, the molecule passes through the lipid membranes and cytoplasm of the corneocytes in the stratum corneum.. I would argue that the non-polar route can be attributed to all three routes of penetration.. In cosmetics, you can utilize skin penetration enhancers to disturb the barrier of the stratum corneum and deliver your product.. Some topical enzymes can even trigger structural changes to the stratum corneum, consequently enhancing penetration.. Natural ceramides are already a prominent lipid found in the stratum corneum, so it's interesting that they can increase skin penetration when topically applied.

Frequent question I get asked, and one that I’ve tried to address before, is this: “If a person’s chest is only 10″ thick, then why should a bullet have to travel at least 1…

The question is a simple one, and it has a “common sense” answer: anyone with “common sense” would see, obviously, that since the average person is only 10″ thick, and the vital organs are located in the middle, then obviously you’d only need a bullet that penetrates six or eight inches at most, right?. A bullet that penetrates 12″ of ballistic gel will very likely not penetrate 12″ of a body.. So when we discuss bullet penetration, we have to divorce ourselves from the notion that the bullet under discussion will penetrate a body to the same degree that it penetrates ballistic gel.. Now, if you’re asking about a bullet fired into muscle tissue (such as a big meaty thigh) then yes, the penetration through muscle will be very nearly the same as the penetration through ballistic gel.. First, you don’t want the bullet to reach the vital organs, you want it to disrupt or destroy the vital organs, and that means it has to penetrate deep enough and still have enough speed that it’ll be able to damage the vitals and not just come to a stop right in front of them.. But we have to factor in that we will almost certainly need the bullet to bust through the ribcage since pretty much all the vital organs are located inside the ribcage (except for the brain stem, obviously), and from a prior study I’ve shown that it takes about 2″ off of a bullet’s penetration capability to get through bone, so add another couple of inches of penetration energy necessary to get through the ribs, and that brings you to needing an absolute minimum of 10″.. That’s why the recommendation from the wound ballistics conferences were that for a bullet to reach the vitals, it would require at LEAST 12″ of penetration power through soft tissue, and preferably up to 18″ if you want the bullet to be able to perform in all conceivable shooting scenarios and from all angles (which is perhaps more of a priority for law enforcement, but isn’t strictly limited to law enforcement).

Have you ever wondered how much of your serums and moisturizers are actually getting into your skin to effect visible change? You probably already suspect that 100% of the product doesn’t get absorbed, but it’s important that your skin is soaking up and processing as much of the key ingredients as it can. So you’ve pro

However, you can increase skin absorption of all the serums, moisturizers, and other products that you use.. Sloughing off the dead skin cells that accumulate on your skin’s uppermost layer is essential for peak skincare absorption.. Dead skin cells can also clog pores and ultimately cause the formation of blackheads.. Even if your pores aren’t clogged and acne isn’t an issue, dead skin cells can still prevent proper skincare penetration.. Together with the exfoliating powder, it can go a long way in helping your skin shed dead skin cells, while also combating existing blemishes.. Apply serums when your skin is still damp. Learn exactly how to layer your skin care by clicking here .. Steam your face. This is why aestheticians often veil your face with steam or a hot towel before a facial!. After removing your makeup, steam your face for only a couple of minutes, then gently exfoliate and move on to layering on your skincare products from thinnest to thickest.. Many people receive this treatment either professionally (which is a lot more intense) or by using an at-home device.. It’s worth it to take care of it If you save your skincare products for only the areas on your face where you see visible issues, you might want to rethink that.

Black Hills Ammunition's founder Jeff Hoffman offers a Ballistic Gelatin 101 class and explains why and how bullets are tested in this medium.

There have been many different methods and mediums used over the years to measure ammunition performance and predict results on flesh.. Ballistic gelatin testing basically involves molding blocks of gelatin, shooting the blocks and measuring the damage you create.. To ensure a valid test, the blocks need to be tested to ensure they are the correct density.. Always look first for the BB when viewing gelatin test results.. With calibration complete, we then shoot the gelatin block.. Upon the impact and penetration of the projectile, the gel block swells.. This is the part of the task that allows us to examine results, learn how the round of ammunition performed on this particular test and compare performance to other ammunition tests or performance standards.. In addition to these standard questions, at Black Hills Ammunition we also record the point it appears that any bullet fragmentation occurred.. We measure to the location of the widest part of the temporary cavity, measured from the face of the gel block.. It does allow us to get a good idea of relative performance of one ammunition to another, but it can’t easily simulate the differences that can occur with different body types or shot placements.. I would almost invariably find the bullet just under the hide on the far side of the deer.. The FBI standards were, of course, not developed to measure hunting ammunition effectiveness.. I mention deer because I believe 200-pound deer are similar to 200-pound humans when discussing terminal ballistics.. My deer hunting combination of a .223 Rem caliber rifle shooting 60-grain soft point bullets almost never penetrated to the 12-inch minimum recommended by the FBI.

Sectional Density was calculated as follows:Light Dart:. SD = .1875 pounds / (.5" diameter x .5" diameter) = .750 pounds per square inch. Atlatl darts do not have as much kinetic energy or momentum as firearms, but have a better sectional density.

They could be holding you back from a healthy complexion.

That makes them hard to identify and even harder to avoid, as they've become the new normal in beauty formulations, from makeup to skincare to haircare.. How to identify silicones on ingredient labels.. Here's why silicones have become so ubiquitous in beauty products:. Beauty companies care more about the bottom line than actually helping your skin.. Silicone-based moisturizers form a film on your skin's surface.. Let's say you use a silicone-based micellar water or serum.. When you use skincare products heavy in silicones, you're not actually hydrating or nourishing your skin, no matter what the label may claim—it's simply a short-term smoothing.. Ingredients such as cyclopentasiloxane are still silicones, even though they don't end in "-cone.". That should help you identify the vast majority of silicones in beauty products.. Moisturizers Serums Face oils Sunscreens Face masks Face mists Acne treatments Anti-aging treatments. Frankly, it really bothers me that so many beauty companies purport to be helping our complexions while cranking out these cheap formulations devoid of natural, nourishing ingredients!

For anyone who knows anything about Superheroes, the phrase for Superman was always “faster than a speeding bullet”. It’s an adage designed to give the impression of great speed. But it begs a really obvious question, exactly how fast is a bullet? Bullets come in different calibers (diameter of the bullet) and this roughly is the determining factor in bullet ...

Bullets come in different calibers (diameter of the bullet) and this roughly is the determining factor in bullet speed.. That’s quite a range but it seems the very large calibers for long range shooting have a bullet speed about twice that of the small caliber rounds.. As the speed of a bullet is quoted for a given caliber (and cartridge), it is useful to see what kind of rounds perform with respect to muzzle velocities.. RoundCaliberMuzzle velocity .22LR0.223 in (5.7 mm)1,500 ft/s (1022 mph)5.56/2230.224 in (5.7 mm)3,160 ft/s (2155 mph).380 ACP0.355 in (9.0 mm)1,125 ft/s (767 mph)9mm0.355 in (9.0 mm)1,200 ft/s (820 mph).38 SPL0.357 in (9.1 mm)1,100 ft/s (750 mph).357 Mag0.357 in (9.1 mm)1,500 ft/s (1022 mph).40 S&W0.400 in (10.2 mm)1,200 ft/s (820 mph)10mm0.400 in (10.17 mm)1,300 ft/s (885 mph).45 ACP0.452 in (11.5 mm)1,100 ft/s (750 mph).308 Winchester0.308 in (7.8 mm)2,650 ft/s (1800 mph).30-06 Springfield0.308 in (7.8 mm)2,850 ft/s (1940 mph).338 Lapua Magnum0.338 in (8.58 mm)3,100 ft/s (2115 mph).50 BMG0.510 in (13.0 mm)3,000 ft/s (2050 mph)Firstly, this was just a table put together to find if there are any useful information that could be determined.. Barrel length – The longer the propellant acts upon the bullet the longer the bullet is accelerating/ The longer the barrel the longer this effect acts upon the bullet.. So a lighter bullet, in a longer barrel with a large cartridge of effective propellant will produce the highest muzzle velocity and thus speed of the bullet.

How does your skin absorb beauty products? Face oils and serums can deeply penetrate the skin for visible results. Let’s get down to skin science.

So here’s a deep dive into skin science to teach you how your skin absorbs beauty products.. Now that you know a bit more about the different layers of the skin, let’s talk about how these layers absorb beauty products.. Although the skin has natural mechanisms to help maintain its moisture levels, they need to be supplemented with a product based on your skin type.. For instance, warm skin will better absorb skincare products than skin that is cold.. Exfoliation removes dead skin cells from the skin’s surface that tend to clog up the routes that your products take into your skin.. Chemical exfoliation involves acids that break the chemical bonds that hold the dead skin cells to the skin’s surface.. Physical exfoliation involves using rough particles to physically scrub the dead skin cells off the skin’s surface.
