  • The only benefit I'm aware of is that they may reduce static flyway (depending of course on what kind of ions they produce.)
  • Interesting questions! I haven't seen any hard evidence of this but my understanding is that most of the conditioning materials deposited on hair will remain until you wash it again because a surfactant is required to help "loosen" them. 
  • Hi Casscass,  Thanks for taking the time to share all your questions. I wish I was well informed enough to know the answer to every single thing you asked off the top of my head. Unfortunately I'm not and I don't have time to research each point rig…
  • That depends on how the emulsion is structured. There are oil in water emulsions and water in oil emulsions. And some emulsions break quickly, others more slowly. It certainly makes sense that if the emulsion could sort of encapsulate the AA with a …
  • Fantastic article! I wish I had thought of the term "Parabenoia."
  • TiGi is part of Unilever and their science based claims are typically pretty reasonable. The "Turbo" one is fanciful but not too outrageous.  
  • The term chiral is derived from the Greek work for handedness and a molecule is called chiral if it differs from its mirror image. (A simple way to visualize this concept is to think of your right and left hand. You can’t fit your left hand in your …
  • "Tigi Turbo" is also a nice bit of alliteration.  
  • Yes, oils can smooth the skin and reduce the amount of light that's scattered. I've never seen hard data on this but it makes sense that this could lead to more damage. I think rather than avoid oil use the answer is to use a good sunscreen. 
  • The quick answer is that EFAs, specifically Linoleic acid (LA) combine with other molecules to create these ceramides that help control the permeability barrier function of the skin.  You can find more info in this post: http://thebeautybrains.com/2…
  • I haven't seen any evidence that this would work. Glycolic acid works on the surface of skin anyway so I'm not sure why you'd want it to penetrate deeply. 
  • No, vitamin C and BP should not be on your skin at the same time because the BP is an oxidant and it will "use up" Vitamin C which is an anti-oxidant. Essentially they cancel each other out. 
  • No, that's not true. A lower sunscreen does not cancel out a higher sunscreen.  However, in theory, two sunscreen values could average together. For example, if you applied 1/2 ounce of a lotion with SPF 60 and 1/2 ounce of a lotion with SPF 15 you …
  • I haven't seen any scientific studies on this but most of what I've read says that filing back and forth is bad for the nail. 
  • 1. Retinol, Vit C and niacinamide are the most effective anti-aging ingredients we've seen. The data on CoQ10 is not as strong.  2. Yes.  3. It depends on the formula but in general we recommend not hacking products like that.  4. Compliment. (more …
  • Ah, I see. I have seen terms like this used to characterize different emulsion structures especially when liquid crystals are involved.  Honestly, I don't understand how it would help skin retain water better (which seems to be the primary benefit b…
  • Never heard of anything like this in cosmetics but here's an industrial product with the same name.  http://www.taica.co.jp/gel-english/alpha/ Maybe they're trying to transfer the technology to skin products? I have no idea. 
  • Yes, that would be great! I'm a bit backed up right now so it'll be a while before I can record a podcast with the answer but we'll certainly use your voice if you can send us a recording.  THANK YOU! 
  • Hair thickening products only temporarily give hair volume they don't make you grow more hair or increase hair diameter. (Unless it's a drug product like Minoxidil.)
  • Yes, it's possible that a product can deliver benefits that a consumer can not perceive. 
  • We approve of any product that makes your skin feel the way you like and that is reasonably priced. Unfortunately, a lot of anti-aging neck creams are over priced and over promised.  
  • Even though shampoos are not optimized for washing your face, most likely nothing will go wrong.  
  • Hi Valia. As cosmetic chemists we don't really deal with these dermatological procedures. Perhaps you could check with your dermatologist. 
  • Hi, Yapon! It's true that the outer layer of hair suffers the greatest damage - from the sun, brushing, and maybe even chemical processing depending on how it's done. That certainly could account for the difference. 
  • The product does contain some peptides that are fairly well established to have some anti-aging properties. But I'm not aware of any topically applied cream or lotion that will truly tighten neck skin (assuming that's what you mean by "anti-scraggly…
  • The testing I was referring to was specifically for hairsprays.  Regarding thermal protection: We've written about that before. You may find this helpful:  http://thebeautybrains.com/2008/04/how-to-protect-your-hair-from-heat-damage/ http://thebeaut…
  • We did a lot of testing on Tresemme hair sprays (the Tres II version specifically) to show it gave the best balance of hold, feel and humidity resistance. You might start with that. 
  • The quick answer is that different polymers balance hold, feel, and humidity resistance differently. The first two you mentioned give a very stiff hold that some people find too crunchy and they can pick up some moisture. The other polymers are desi…
  • Makes sense although I guess that answer is vague enough that it could work either way. It also depends on who was giving you the answer. A lot of times the scientists in the company aren't the ones directly corresponding with the public. 
  • Interesting question (once you were properly caffeinated.) I haven't seen any data comparing the two delivery vehicles but my hunch is that it doesn't make any difference.
