INGREDIENTS: Figuring out what's "hypo-allergenic" and "non-comedogenic" - 0 views

    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.

    Like you mentioned before, toxicity is something interesting we could look into. Toxicity with regard to both us as humans, and our environment, like the aquatic life that would come into contact with some of the chemicals in these sunscreens. Katie, maybe you should add this to your blog post :)

    that's a good point, that maybe you have the same eyeshadow in different colors, yet each of those different colors is actually made up of different stuff. It kind of makes you think... is there one color that is better than the rest because of its components? hmm...

    *beetles not beatles. Haha we don't want crushed brit bands in our cosmetics :) yeah that's a really interesting page. I think I just spent the last 10 minutes scrolling through all the things and picking out the ones that I recognized from the back of food wrappers. But I wish they would put what color the additive is, so you can see what colors go into your products. But maybe they didn't put the color because it changes based on the chemistry of the item that it's going into? that could be interesting to look into...

    really helpful guide to arbutin, the most common skin lightener
  • Jenny Mu on 22 Nov 12
     
    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

  • Jenny Mu on 27 Nov 12
     
    yeah It's funny how some rumors start. this article mentions that people thought SLS would degrade into nitrosamines, which are carcinogenic, but that doesn't make any sense at all since there isn't even a nitrogen in SLS, but there are in nitrosamines... welp that reminds you that there are some really uneducated people in society

  • And while these are all products that are topically applied—a concept consumers are familiar and comfortable with—more consumers are coming around to the idea that the same ingredients that are found in lotions and potions might also be able to influence outward appearance when incorporated in the diet.

      Which way is better? topical treatments or oral ingestion
  • “There is human clinical evidence that these yellow carotenoids act like internal sunscreen to protect and improve skin health,” he says, referring to a 2007 study that tested the oral and topical effects of lutein and zeaxanthin over 12 weeks. (P Palombo et al., “Beneficial long-term effects of combined oral/topical antioxidant treatment with the carotenoids lutein and zeaxanthin on human skin: a double-blind, placebo-controlled study,” Skin Pharmacology and Physiology, vol. 20, no. 4 (2007):199-210.) “Statistically significant, favorable effects were seen on three skin function outcomes, including hydration, photoprotection, and lipid damage,” says Bhattacharya. “Higher oral doses of zeaxanthin were shown to provide effective protection against sunburn, which could help reduce the risks of skin cancer, premature aging, and wrinkling.”

      What inside them is acting like an internal sunscreen? Chemically, how does it work?
  • Pycnogenol is one of the few antioxidants shown to effectively neutralize all oxygen radical species. It says this is especially important to the skin, as even low-to-moderate UV exposure generates oxygen radicals in the dermis.

      Neutralization of oxygen radical species. Once again, we should look into the chemical process of how this happens. The transfer of electrons etc.

      This article states that "creams with ceramide, peptides, AHA, and BHA are effective." in helping the cream get absorbed by the skin we should look more into those and figure out chemically what is making these compounds so essential to good skin care.

    Anti-aging cosmetics might be a good topic, but once again, as long as we don't stray too far into biology and stay focused on the chemistry of the topic.

    Yeah it seems as though there isn't really one certain chemical process that prevents all types of aging, but rather there are a bunch. I wrote an article about antioxidants, but another widespread one seems to be alpha hydroxy acids AHAs

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

  • 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.

  • “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.

      This just goes to show that these cosmetic companies are just using whatever material is more expensive in their face creams so they can jack up the price. First gold, then platinum...

       I was just wondering, what justifies the extreme prices of these skincare products. What materials or chemical processes are needed to produce them, and do they really have any effect? Personally, if I was paying $13,300, I would expect it to do a lot more than just moisturize or reduce fine lines.
