Beauty Questions

Question 1 – Rachel asks, “What is an oxygen facial and do they really work?”

The bottom line is that oxygen facials have not been proven to provide any benefit that you can’t get from a standard moisturizer treatment or exfoliation. And at from between $200 and $500 a treatment, they certainly don’t seem worth it to me.

Question 2 – Hi BB, I’m a professional hairstylist and first of all I want to thank you for all of the wonderful information you provide. It can be hard to find accurate scientific information in the beauty industry and it means a lot to me. I have a question about Biolage by Matrix’s new hair color launching this fall. They claim it to be 82-100% plant based with only 2-9 ingredients. I was pretty skeptical until I saw a video of them mixing it. It comes in a powdered form and they mix it with hot water, not developer. It looks exactly like traditional henna, but it comes in up to 20 shades. I was always taught to avoid henna hair color as any shades besides the original copper shades have to be made using compound dyes which can have bad reactions with bleach or other chemicals used in the salon. They claim this color to be completely free of metallic dyes and to be compatible with bleach. Are they just mixing it with direct dyes or mixing it with other plants besides henna to make these colors?

Question 3 – Sam says… I bought a shampoo. Specifically Garnier Ultimate Blends [Honey Treasures Shampoo]. It had suddenly stopped lathering and the shampoo just sits there doing nothing. Does light degrade shampoo? It was in a glass jar. I know shampoos comes in clear bottles so I’m not convinced light is the issue. It [wasn’t] out of date either. I’m wondering what could have caused this and if once the lathering stops does this impact on the shampoos ability to clean? Thanks. Sam  

Question 4 – Is it ok to use body wash in place of hand soap?

Question 5 – Ashley asks…In episode 172 you talked about the different variables that affect product price. What about brands that say they are made in small batches? The claim is that due to the small batches the products are made in, less preservatives are used which means there are more active ingredients. Is this true and are there any clear advantages to making products in small batches? I use Glymed Plus.

On this episode of the Beauty Brains we answer a number of beauty product questions and talk about big companies and the brands they own.

Beauty Questions

  1. What is the big deal about squalane
  2. Does the number of ingredients in a product impact its effectiveness?
  3. Are dip nails safe?
  4. And how do anti-dandruff shampoos work?

Beauty Questions

Gillian – What’s the deal with squalane oil? What’s the difference between squalane oil and squalene oil, and how do they compare to other oils like rosehip oil? She’s seen claims that squalane is considered the best oil for all skin types? Is that really true? It is more shelf-stable and less likely to go rancid because it is a saturated oil versus rosehip oil being polyunsaturated. Excellent hydrator, anti-oxidant, oil controller and anti-bacterial that also sinks into skin better than other oils. What can a $38 oil (Peter Thomas Roth) do that a $8 cannot (Ordinary)?

Ceyda asks – Does a product’s, say moisturizer or serum, number of ingredients matter for its effectiveness?

Ana from Instagram says, “I am enjoying your podcast and have heard you talking about the efficacy of different nail polishes, but am concerned about the safety of gel nail polish and SNS – which some people call ‘dip’ nail polish. I am concerned about what it will do to my nails with continuous use. Do nails need to ‘breathe?’ I appreciate any feedback.”

Beauty Questions

Question 1 – I heard that if you apply henna (just henna) on your hair, you can’t apply regular color on the hair (the one that uses peroxide), or vice versa. I would like to know if this is true, and if so the scientific explanation behind it. I do love the show and I would really appreciate if you could answer my question

Question 2 – Monica says she can’t find a true red lipstick. I try one on and it reads pink, brown or orange. I heard they outlawed an ingredient to make it red. Did this really happen? Can you get a red lipstick?

Question 3 – Alicia from Instagrama huge fan of the podcast, didn’t know who to rant to, so she contacted us. Alicia says, “This is the most outrageous blog post I have ever read concerning sun protection. Where is she getting these claims!? The headline: ‘Is your sunscreen doing more harm than good? Probably.’”

Question 4 – Is hygral fatigue a real thing? You shouldn’t let hair stay wet too long. Is this true?

On this episode of the Beauty Brains we cover a variety of topics for both hair and skin. On this show…

  • How does Hard water affect hair?
  • Should you be Patting or smearing on skincare products?
  • What natural ingredients that are good for hair?

Plus, we look at the Jacklyn Hill lipstick controversy and whether 0% aluminum natural deodorants are really a thing.

Crappy claims –  (Maybe need a title for this segment but the idea is to call out bad and misleading marketing claims)  Dove launches a 0% aluminum deodorant. Deodorants have never contained aluminum!

Kitchen Cosmetics

Will lemon juice lighten up darkened armpits?

No, but I can see how this lemon juice myth got started. There is a small amount of Vitamin C in lemon juice which some people believe will lighten skin. And there is citric acid in it which some people think might help exfoliate. But it’s unlikely to be of much help and it can also cause problems. Lemon juice can react with the sun to cause a rash.  Having a rash under your armpits is no fun.

Beauty Questions

Question 1 – Water Hardness

Question 2 – What natural hair ingredients are effective?

Question 3 – Should you pat or smear your skin care products?

There isn’t a lot of evidence that patting is better for application than smearing. The most important thing is that you apply sunscreen at all.

On today’s episode we answer beauty questions about :

  • Should one be worried about tree nuts in cosmetic products?
  • What’s the difference between a toners and astringent?
  • How does one spot a bad dupe versus an affordable product that works?
  • Why do some nail polishes last longer on some people than others?

Beauty Science Questions

Should we be worried about tree nut allergens in cosmetic products?

Tree nuts are considered major food allergens. The actual nut or derivative from the nut, like an oil, may contain a protein or proteins that elicits an allergic reaction. In food, which is where a majority of the allergic reactions take place, it is a requirement through the Food Allergen Labeling and Consumer Protection Act (FALCPA) that requires declaration of any tree nuts or possible contamination with tree nuts on the ingredient label, as well as any of the other major food allergens that exists. FALCPA does not cover cosmetic ingredients.

In short, cosmetic products don’t have labeling requirements for tree nuts in the US or EU that indicate a similar warning to food. In long, it’s not easy to prove scientifically that tree nuts are an issue topically as they how they are used in cosmetic products – and topically, meaning on the skin and not in for products intended for the oral mucosa.

Essentially, they couldn’t find sufficient evidence that applying peanut oil to skin was an issue consistently, so they couldn’t create a safety threshold.

There is no labeling requirement and I’m not aware that they have established guidelines for other tree nuts. In the US, this regulation does not exist.

All that being said, if you have any concerns about tree nuts in cosmetic products, even if they’re topical, I would consult your allergist and certain avoid products that come in contact with the oral mucosa or broken skin.

Question 2
Celeste says…Good morning, Perry and Valerie, Not sure whether you’ve answered this before, but what is the difference between a toner and an astringent? Is either one effective at what it claims?

Skin toners and astringents are terms often used interchangeably. However, many people consider that there are differences in the way they are formulated with toners using glycerin while astringents use alcohol. The reality is that there are plenty of astringents that use glycerin as well as alcohol. Witch hazel is another popular astringent ingredient. Most toners that I found were alcohol free.

Toners and astringents are frequently included as part of a three-step skin care regimen (cleanse, tone and moisturize). But let’s get to the more important question, do you really need either of these products? Let’s take a look at the ingredients used in toners to understand what they really do for your skin.

What does a toner do?
Toners usually claim one of two things – they can remove excess oil and dirt that your cleanser left behind or refresh and moisturize skin. Historically, toners use alcohol and/or witch hazel which can make your skin feel tight and firm and can feel refreshing. However, more recent versions of toners have moved away from this approach due to the drying effects of alcohol. Thus the split in terms Astringents and Toners. These types of toners are alcohol free and often use glycerin and panthenol (vitamins) to give skin the same kind of refreshed feeling while being more soothing to skin.

Do you need to use a toner?
I would say probably not but it is certainly a case of personal preference.. A decent cleanser should remove excess oil, dirt and makeup. And the truth is, you do not want to strip every last molecule of oil from your skin. Only grime, makeup and excess oil on the surface needs to be removed. The sebum (oil) that your skin produces naturally is actually good for your skin and is best left undisturbed. Toners, especially alcohol-based ones, tend to strip everything off, leaving the skin dry and irritated. As far as alcohol-free toners, they may feel good and leave a little moisture on your skin but they don’t really do much, particularly if you use a moisturizer anyway. The people that may benefit from using a toner are women with exceptionally oily skin (usually teens) or women with very dry skin. If your skin still feels sticky and oily after cleansing, a toner can help remove that excess grime. Women with very dry skin may find an alcohol-free toner to be soothing.

I have a question about nail polishes, and that it appears to be such differences for how long they last on different people. I get that there is a vast variety for how you apply the polish and your everyday wear and tear, but is there any difference in peoples nails that would effect how long nail polish lasts? Is there anything different with the nails of some people that makes nail polish not last as long? All the best, Jenny

The reality is that people’s nails are chemically very similar. I looked at a study called “Age and Sex Variation in Lipid Composition of Human Fingernail Plates” in the journal Skin Pharmacology and Physiology and while there were some difference between people 10 years and younger and adults, there were no significant difference between people at different ages as adults. Now, these looked at the age groups as groups and there was some variability within the age groups, but the differences I don’t think are significant to impact how well nail polish will stick on someone’s fingers. This will be much more affected by the

Method of application, the type of nail polish used, whether you put a base coat, the speed at which the polish is dried, the quality of the nail polish (is it old?), and the exposure of the hands to different environments. Things like washing dishes, cleaning the house, exposure to alcohol, etc. can all impact how long nail polish will last. It’s these environmental conditions that matter much more for long lasting nail polish than any difference in people’s nails.
