I’m a dinosaur in beauty blogger years. I started my blog in December 2011, and in the last 10-ish years, I’ve learned a lot as I’ve read way too deeply into pretty much everything. I recently had the urge to go through some of my older posts, and unsurprisingly, I’ve said quite a few myths in the past (like the …
I’ve looked at some more 5 Minute Craft beauty hacks – they’re a mixed bag. Some of them are awful, some of them are actually not that bad. This set includes a few beauty hacks I’ve seen around the place: Aspirin for pimples DIY glitter eyeshadow Activated charcoal for teeth Wasabi lip colour Dark circles and tea bags Check it …
Glycerin’s in a lot of skincare products because it’s an awesome humectant moisturiser that can grab onto water and hold it to the skin. It’s also very cheap to buy at the supermarket ($9.35 for 200 mL at Coles in Australia, $6-7 for 473 mL/16 fl. oz on iHerb or Amazon).
What can you do with it? Here are some (low-effort) suggestions:
Make a moisturising nail polish remover
Most nail polish removers have this issue where they either work very well but dessicate your cuticles, or they’re kind to your skin but take forever to dissolve nail polish. This acetone-glycerin mix blends the best of both worlds: acetone will dissolve your nail polish like no one’s business, and glycerin will stop it from stripping away moisture. Here’s my recipe for a gentle but effective DIY glycerin/acetone remover.
Make a hydrating toner
Glycerin is found in tons of toners thanks to its ability to hold onto water, which can revive dehydrated skin. Plain water will normally dehydrate your skin because it makes your skin more permeable, then when it evaporates it makes your skin drier than before. Adding glycerin stops this from happening. The only problem with this is that glycerin/water combos need preservatives if you leave them for more than a few days, because glycerin is very good food for bacteria (if it’s above ~50% glycerin content it’s a bit like honey so bacteria can’t survive…but it’s also sticky and thick like honey so it isn’t pleasant to have on your skin all day).
The answer is – it depends. Gah! Read on for the gory details…
Are you getting enough biotin in your diet?
Nutritional supplements generally only make a difference if you’re not getting enough of that nutrient normally, and biotin seems to play by this rule.
The daily recommended intake of biotin for adults is 30 μg/day, and a Western diet generally contains enough biotin. You can find biotin in leafy green vegetables, nuts (peanuts and almonds in particular), avocados, corn, cooked eggs, liver, salmon and meat. Some intestinal bacteria make biotin, which could also contribute to your overall consumption.
Some factors can decrease your biotin though. Biotin seems to be lower with high alcohol consumption, smoking, gastric acid disorders, in burn patients, epileptics, athletes, the elderly and with some inborn genetic disorders. Pregancy and breastfeeding also decrease biotin.
Eating uncooked egg whites can also decrease biotin, even though cooked eggs are a good source! Raw egg white contains a protein called avidin which binds tightly to biotin, preventing it from working. Cooking the egg destroys the avidin.
I haven’t done a nail art post in a while, so I thought I’d finally post a mani I did recently. I painted this ladybird design using Furless Bitch, a solid black, and Sea Siren Cabin Fever, a bright red creme. Unfortunately Cabin Fever’s designed to be worn on its own, so it took quite a few layers until the …
The news broke recently that nail polish can harm your health (again!). This time, it’s triphenyl phosphate, a chemical used in nail polish to increase flexibility – it’s also used as a fire retardant. It’s a potential endocrine disruptor (“it could make you fat!”), and was found to be increased around seven-fold – or soit wasreported. In particular, the Environmental Working Group (the people behind the “sunscreen is toxic” story every summer) has been the source for most of these articles.
Triphenyl phosphate (TPHP) is a chemical used in plastics to improve flexibility and as a flame retardant. A handful of animal studies and in vitro studies have suggested that it could be an endocrine disrupter which affects your hormones – in particular, it could potentially affect reproductive health and lipid metabolism (that’s where the “nail polish makes you fat” headline comes from). A couple of epidemiologicalstudies in humans have also found correlations between TPHP and decreased sperm counts. However, all of this is far from conclusive evidence, and as you’ve probably gathered from being on the internet in the past 5 years, it’s almost like every chemical ever can be linked to endocrine disruption if you try hard enough.
In the body, it’s metabolised quickly to a related chemical, diphenyl phosphate (DPHP), and excreted in the urine.
What studies were performed?
The paper reports two main studies, performed with a nail polish containing 0.97% TPHP by weight.
“Cohort 1”
16 female students removed any nail polish they were wearing 72 hours before the experiment.
They then collected one sample of urine (T1).
24 hours later, they painted their nails with two coats of the same clear polish.
2 – 6 hours later, they collected another urine sample (T2).
10-14 hours later, they collected a third urine sample (T3).
“Cohort 2”
10 females removed nail polish they were wearing 72 hours before the experiment.
All urine was collected in the study, either for 24 hours (6 subjects) or 48 hours (4 subjects).
The participants first collected urine for 24 hours, during which they didn’t use nail polish (Control Phase).
The subjects were divided into two groups:
Half painted their nails with 2 coats of the polish (Nail Painting Phase).
The other half painted synthetic nails attached to latex gloves, then waited an hour before throwing out the gloves (Glove Painting Phase).
After waiting at least 7 days, the groups swapped over (this is what’s known as a crossover study, where each person essentially acts as their own control).
The urine samples were analysed for DPHP content. To account for dilution effects (e.g. if one person drinks a lot of water), the urine samples were corrected for specific gravity (SG).
Discussion
I don’t have a comprehensive background in designing biological studies or in statistical analysis, but nothing really rings any alarm bells for me (but I’m happy to be corrected if anyone spots any shifty manipulation!).
Does wearing nail polish increase the amount of TPHP in your body significantly?
In terms of concentration, yes, it appears so, in both experiments – to quote the study, “nail polish is a likely source of exposure to TPHP and that use may result in exposures substantially greater than background levels.” (Background means in the absence of nail polish.) It’s worth noting that you have to wear the nail polish, not just inhale it – Glove Painting didn’t cause the same increase. As well as the hard numbers, it’s pretty apparent, visually, from the graphs of urine DPHP from Cohort 2 (which I’ve painstakingly re-graphed to hopefully avoid any awkward debates about Fair Use).
I’ve been trying out a whole bunch of things lately – here are the ones that’ve made it to the top of my “yes!” pile. Urban Rituelle have released the new Dreamweaver range, which includes 2 summery fragrance blends – Island Blossom, a mix of jasmine, frangipani and berries, and Coconut & Lotus, which is a sugary blend of coconut, …
Update (2018-12-05): Since Danny of Mentality Nail Polish has generously sent me a cease and desist for defamation as seen in the comments section, I’d like to interrupt your regularly scheduled programming to clarify (even though I think it’s pretty damn clear already) that the causes of the issues are science-based opinion and speculation.
Welcome to every nail polish lover’s nightmare – nail disease. Wearers of Mentality Nail Polish have been waking up to this horror:
Thanks to @dmm_nails for letting me use images of her poor nails!
The technical term for this is onycholysis – when your nail detaches from the underlying nail bed. It’s painful, it’s inconvenient, it’s ugly, and you have to wait til it grows out to recover (if it ever does). There are lots of write-ups on the multitude of legal and ethical fuck-ups that Mentality Nail Polish have made in handling this issue, so I’m not going to rehash that in this post (you can read all about it at The Mercurial Magpie and Ashley Is Polish Addicted, amongst others). Like many others, I’ve been racking my brains wondering what exactly went wrong.
Of course, we won’t know for sure until someone gets analysis results back from a lab. Mentality “almost have enough funds” for an analysis now (although they’ve reportedly known about this problem since September last year, and a GCMS can ordered for under $100 and they haven’t even done that, so I’m guessing we’ll hear the results in 2020 or after an injunction?). But since they’re going full Laganja on this one, I’m not holding my breath.
In the meantime, here’s my analysis of all the speculations that have been flying around. Keep in mind that these are just speculative hypotheses and my opinions on them only – they’ll change as we get more complete information (which is pretty tricky, as Mentality have been deleting their posts, and I’m having trouble finding some of their past statements… I’m sure a lot of links I currently have here will die!). As I’ve read more, I’ve changed my mind about 7 times about what I think the most likely cause is. I’ll be updating the possible explanations as they develop.
What we know
Indie makers typically buy a pre-made base from a larger manufacturer, then add tints and glitters. This is what Mentality have supposedly been doing.
Mentality were using Tevco and Fiabila base (3/4 free), but sometime late last year/early this year they switched to a base from Arminex (5 free – parent company of Nubar). They’ve since switched back. They do not make nail polish base themselves… “yet”.
The problematic polishes aren’t isolated to the neons, although the neons were very popular and consumed whole barrels of the base, so they’re the most commonly reported.
Mentality degassed all the bases to “remove air bubbles and found that Arminex base is very foamy, compared to the other manufacturers whose polish base does not foam upon degassing.”
Not everyone who wore them were affected (around 40 people have reported reactions to Mentality so far). The earliest case was @spilledmilknails, a Mentality swatcher, in September 2014.
From people who own the affected polishes:
The polishes with the different base smell very “chemical” “like melted plastic”, and the smell seems to have gotten worse over time.
Some people were reporting stinging, itching and redness upon application.
People who experienced nail detachment generally wore them for longer periods, while swatchers who removed them immediately were generally affected less. There are exceptions though – apparently someone swatched them for 4 hours and ended up with nail damage a few days later.
Faulty Arminex Base Theories
This is the angle that Mentality have been pushing, which makes sense because it means less liability for them and hence their best chance of getting out of this without being buried in a steaming turdpile of legal troubles.
