Skin Deep - Gold Face Cream - A Costly Leap of Faith - NYTimes.com - 1 views

www.nytimes.com/...27skinWEB.html

shared by Jenny Mu on 13 Oct 12 - No Cached
  • People who sell creams with visible gold flecks talk about the ability of those flecks to warm the skin and make it conducive to other ingredients. People who sell gold in nano form — that is, in microscopic particles suspended in a liquid mixture known as a colloid — look down on this crowd, saying that gold can confer benefits only when it is broken down small enough to penetrate the skin.
  • But is it true that gold has therapeutic qualities? That depends if you ask someone who is selling it suspended in cream or someone who went to medical school. Dermatologists speak with one voice, saying that gold cannot help you, but it absolutely can hurt you, causing inflammatory reactions like contact dermatitis (which may be what happened to me). In high doses, gold can be toxic, but these products probably don’t contain enough of it to make that happen, doctors say.
  • At best, they do nothing, and at worst, they can give you irritation of the skin,”
  • ...13 more annotations...
  • “intensive medical searches on this very ingredient” and found that “there are absolutely no scientific studies that show that gold has any effect in firming or revitalizing the skin, nor that it reduces wrinkles or gives skin a plumped, golden glow.”
  • “Colloidal gold does help to maintain your skin’s elasticity and firmness,” she said. “Gold itself is known to have very soothing benefits to it.”
  • a line of products that contain colloidal platinum — including a cream that costs $1,000 an ounce
  • outlined a number of benefits: gold, she said, is hypoallergenic, stimulates blood circulation, reduces sunspots and acts as an antioxidant.
  • “The gold actually acts like a small charger, because it’s metal and we have electricity in our bodies,” she said. “Whenever gold comes into contact with our bodies, it gives a boost of activity, which is good for restoring the lost elasticity properties of the tissue.”
  • Cosmetics makers also habitually cite the use of gold in medicine, where it is given to patients with rheumatoid arthritis and has been used — only experimentally — as a possible cancer treatment. Debabrata Mukhopadhyay, a professor and cancer researcher at the Mayo Clinic, said that while gold nanoparticles show promise, they are “highly toxic when injected in high doses in mice.” And the size of the nanoparticles matters a lot, he said, adding that it was unclear if the particles in the gold face creams were the right size to penetrate the skin.
  • “As a scientist, I am very skeptical unless I see research,”
  • Ms. Genovese pointed out that people keep buying her company’s gold line because they perceive that it works.

    I think that talking about skin lightening, which is really important in old ladies with dark spots, could be a good blog post. I think this site is really helpful in terms of explaining things thoroughly but in an easyish to understand way too. It appears that because theres a glucose attached to the molecule of arbutin, it makes it much more effective. This kind of relates to chemistry so thats good :D
  • Andrew Kang on 22 Nov 12
     
    ooh its good that it explains the mechanics of it since usually people just put stuff on their face w/o knowing how it works. i'll cover this one.
  • Katie Rigdon on 28 Nov 12
     
    Wait this is a great article because it really explains the detailed structure of arbutin as well as how it works to lighten skin. The alpha vs beta aspect could also potentially be interesting to expand upon.
  • Amanda Jara on 28 Nov 12
     
    From what I understand by reading it, the glucose added onto the hydroquinone makes it safer. There was also a mention of 'anti-cancer activity' on melanoma cells. This can definitely be expanded upon since it is something so different from everything else researched.

  • Katie Rigdon on 11 Dec 12
     
    The chemistry behind soaps could be a really interesting topic. I know in AP Chemistry we were talking about how some soaps just remove the oils on your skin, but it is also really important for soaps to moisturize your skin as well as clean it so that your skin doesn't get really dry.
  • Katie Rigdon on 11 Dec 12
     
    Sorry I just realized that that last comment wasn't totally related to the article but it is another aspect of soaps that we could look into. It could also be interesting to compare the ingredients of different soaps and see if the differences really affect their performance.
  • Andrew Kang on 12 Dec 12
     
    It's not related to this article but it is related to what we're learning in class/cosmetics - I smell a possible blog post.
  • Amanda Jara on 14 Dec 12
     
    Going off of what Katie said about soaps removing the oils on you skin, I know some people who have really sensitive skin and actually break out into rashes after using certain soaps. Maybe we can look why that happens, (is it the removal of oils, or the addition of chemicals that are supposed to help moisturize the skin). From there we can probably find the ingredient that leads to such effects.
  • Andrew Kang on 14 Dec 12
     
    That's a good idea - the "or." Perhaps it is actually both? And these ingredients that supposedly help moisturize your skin, how are they passing testing if they dry it out? Things to look into.
  • Katie Rigdon on 16 Dec 12
     
    It looks like a this topic could really tie in with the last topic in advanced chem in terms of polar and non-polar molecules. Yay connections :)
  • Amanda Jara on 16 Dec 12
     
    Maybe we can go even further and see if it is the different combinations of ingredients that causes reactions. Perhaps it may be the case that one ingredient may be harmless if it is alone, but when combined with something else, it can change its properties.
  • Jenny Mu on 17 Dec 12
     
    I'm in the process of writing a blog post on soaps, and iin my research, I basically found that soaps are made from fats and salts, which make the non polar and polar, and so that lets them bind to non polar things like grease and polar things like water, and they lets them wash stuff away. Thats a way we can relate this to the stuff we're learning in class :)

    Really interesting article although this seems to be straying a little from cosmetics. It also might be hard to relate this back to what we are discussing in class. Looking at cosmetics that also help heal people's bodies could be a possible blog post.

  • Jenny Mu on 12 Dec 12
     
    I like the idea of just looking at how it penetrates the skin, and I think we can relate it back to cosmetics through that because a lot of cosmetic products need to find effective ways to get their ingredients to penetrate the skin, because otherwise, they wouldn't really work. just an idea
  • Amanda Jara on 14 Dec 12
     
    Kind of going off of what Katie said about cosmetics healing the body, you can always find the foundation commercials advertising regenerating ingredients that "take years off your face." it can be a different angle to discuss instead of usual topic of how facial cosmetics cause premature aging.
  • Andrew Kang on 14 Dec 12
     
    People often forget that cosmetics also encompasses things that benefit your health as well. I made one blog post already about how anti-aging creams work but I never looked at foundation and other products.

      The article kept stressing the benefits of colloidal gold as opposed to gold in flakes or just applied to the skin. Perhaps we could look at nanochemistry in cosmetics - it was nanoparticles that gave the colloidal cream its advantage and with anything you apply to your skin perhaps there is consideration given to the substance on the molecular scale for its efficacy.
    • Jenny Mu
      Jenny Mu on 17 Oct 12
       
      But we should also consider the element itself. Whether in nanoparticles or in flakes, what scientific evidence is there that gold is good for the skin? Or is it just one big, expensive scam...

    Sunscreen (also known as sunblock) is a lotion, spray or other topical product that helps protect the skin from the sun's ultraviolet (UV) radiation, and which reduces sunburn and other skin damage, ultimately leading to a lower risk of skin cancer.
  • Jenny Mu on 26 Nov 12
     
    This one helps further explain what I posted down there about para-amino benzoic acid, titanium oxide, and zinc oxide. It seems that para-amino benzoic acid is similar to oxybenzone, which this article says absorbs the UV rays, which is how it helps protect your skins. The metal oxides merely reflect them off. I think the mechanism by which sunscreens help protect is interesting

    Hey guys so the interesting aspect of this article is the part about emulsions. Emulsions are basically mixtures of water, oil, and surfactant (something that binds to both oil and water and therefore helps them combine). This topic is interesting in terms of moisturizers because your skin needs oil to moisturizer it but just putting oil on our skin is very messy. Emulsions allow for neat and tidy moisturizers for our skin!
  • Jenny Mu on 19 Dec 12
     
    So bringing back an old article, do you guys think we could relate this to what we're learning in class by looking at the process of mixing water, oil, and surfactant. Because water and oil naturally repel, do you guys think that getting them to mix together would be an endothermic reaction, because thats not how they want to be? Just a random thought :D

The Insect Repellent DEET | Pesticides | US EPA - 2 views

shared by Katie Rigdon on 12 Dec 12 - No Cached
  • After completing a comprehensive re-assessment of DEET, EPA concluded that, as long as consumers follow label directions and take proper precautions, insect repellents containing DEET do not present a health concern. Human exposure is expected to be brief, and long-term exposure is not expected. Based on extensive toxicity testing, the Agency believes that the normal use of DEET does not present a health concern to the general population. EPA completed this review and issued its reregistration decision (called a RED) in 1998. (More about REDs)
  • Read and follow all directions and precautions on this product label. Do not apply over cuts, wounds, or irritated skin. Do not apply to hands or near eyes and mouth of young children. Do not allow young children to apply this product. Use just enough repellent to cover exposed skin and/or clothing. Do not use under clothing. Avoid over-application of this product. After returning indoors, wash treated skin with soap and water. Wash treated clothing before wearing it again. Use of this product may cause skin reactions in rare cases. The following additional statements will appear on the labels of all aerosol and pump spray formulation labels: Do not spray in enclosed areas. To apply to face, spray on hands first and then rub on face. Do not spray directly onto face.

    I'm not sure if this is relevant, but I remember one time I sprayed bug spray with deet all over my legs, and some of it got on my toes, and my nail polish started to dissolve and come off like it does when I use nail polish remover... Maybe there is some chemical relationship between deet and acetone, perhaps the structure or something else that causes both to be able to take off nail polish. Then again, this isn't the most relevant/pertinent of questions. Just an interesting thought I had.
  • Andrew Kang on 12 Dec 12

  • Syn-Coll stimulates the collagen synthesis in human fibroblasts. Skin aging and chronic UV exposure particularly, leads to degenerative changes in skin. The degenerative changes in skin are characterized by distinct alterations in the composition of the dermal extra cellular matrix.
  • Tissue growth factor is known as the key element in the synthesis of collagen and binds to a particular sequence in the TSP molecule. This sequence is known as ARG-PHE-LYS.
  • As a molecule able to activate TGF, Syn-Coll is considered to be an ideal aqueous based peptide. It contains a unique sequence designed to mimic the human body's own mechanism to product collagen via TGF. Accordingly, Syn-Coll actively compensates for any collagen deficit, thus making the skin look younger and rejuvenated.
  • The results of the Syn-Coll clinical studies are astounding. After 84 days of twice-daily application, a panel of 60 volunteers experienced 2.5% Syn-Coll parameters average relief (Rz) and maximum relief (Rt) significantly decreased by -12%: -22 μm and -36 μm respectively (p= 0.05) characterizing smoothing and anti wrinkle effects.

    I definitely agree that Sodium Lauryl Sulfate is a pretty big issue, you always see products boasting that they are "Sulfate free!" and what not.

But I think we should do more research into what makes that compound so dangerous and why its bad to be in personal products

    Yeah! It's also kind of interesting because there are two different types of sunscreen: chemical and physical. I can talk about the differences there too!
  • Amanda Jara on 28 Nov 12
     
    I wonder if the sunscreens that created the thick, white 'goo' is stronger and more efficient than the transparent sunscreens used today. Most bottles of sunscreen say to reapply within a certain number of hours, so it can be interesting to see how older formulas of sunscreen compare to those most commonly used today.
  • Jenny Mu on 28 Nov 12
     
    That's a really good point, Amanda. Those thick white sunscreens that just show up on your skin opaquely probably helps to protect your skin just by blocking out the sun... Nowadays, since no one wants to have gross, whitish stuff on their face, sunblock has become clear so that you can't see it. I think they protect you from the sun by either absorbing the rays, like with oxybenzones, or reflecting the sun in tiny particles of metal oxides. Changing sunscreen to be transparent was probably for aesthetic reasons, but which way is better for sun protection? Is just straight up blocking out the sun with an opaque covering better or are these new, fancier ways better...
  • Amanda Jara on 29 Nov 12
     
    The Nanomaterials article above mentions something about using smaller particles between 20-200nanometers which make the lotions nearly clear. Because of this, I would hypothesize that it is not as effective. In addition, continuing with this topic, (despite this being from the above article) the nanoparticles seem to have a negative effect on the aquatic life and their environments.
  • Jenny Mu on 30 Nov 12
     
    hmmm interesting that you say that we could tie in environmental effects into one of our blog posts maybe? Perhaps about the chemical compounds in our personal products, and how they affect the environment? I think sunscreen is a big one, because a lot of the time, people just go into the water right after they put it on, so it can come off into the water and affect aquatic life. Good idea

    This is an easy to read, interesting blog post about the usage of worlds like "hypo-allergenic" and "non-comedogenic" on cosmetics, and what it actually means chemically for products to be labelled with those words. This kind of addresses what we were talking about on the simvastatin article, about cosmetics that can help clear skin Things that are non-comedogenic do not necessarily clear skin, but they do not cause acne. We could start there, looking at chemical compounds in cosmetics that can cause acne and that don't cause acne and then look into how to treat it.

    I think the allergic reaction to the arbutin was only specific for that one person who wrote the article. From this review article, it seems as though arbutin is used in a variety of skin lightening products, because it reduces the melanin production, which causes dark spots and what not.

    Interesting article about causes of skin allergies from WebMD. Looks like fragrances can play a big part in allergies and it also looks like there are some things that you can do to prevent these allergic reactions.

    Interesting - but we have to be careful not to stray into the biology of allergies when explaining why they occur.
