Mineral Oil Myths Explained: Cancer, Safety, and Skincare Benefits

It's been awhile as life has gotten busy! But I'm back with more skincare geekery - this time on mineral oil! I've wanted to write this post for awhile, because over my years being an amateur skincare nerd, I've noticed lots of fearmongering with respect to mineral oil. Some people believe that 1) mineral oil is bad for you because it prevents your skin from breathing, 2) mineral oil causes cancer, or that 3) you shouldn't use it because it is derived from petrochemicals. I'll be taking a look at these three myths in this post!

First though, a little bit of a primer into mineral oil itself.

What is mineral oil?
Mineral oil is a liquid mixture of hydrocarbons (i.e. molecules comprised only of carbon and hydrogen atoms) obtained from petroleum, and consists of saturated hydrocarbons having carbon numbers predominantly in the range of C15 through C50. As seen in the bottles of baby oil, it is easily recognizable as an oily transparent liquid. It's manufactured by the distillation of petroleum, and then followed by refining of residual fractions to meet the standards for cosmetic grade mineral oil.

Skinceuticals H.A. (Hyaluronic Acid) Intensifier Review and Ingredients Analysis

Skinceuticals recently launched their HA Intensifier, or Hyaluronic Acid Intensifier. As the name suggests, it's a serum/booster product with hyaluronic acid - but more than that, Skinceuticals also claims that the HA Intensifier will also help to boost your skin's ability to make its own hyaluronic acid, beyond just replenishing it. Application-wise, Skinceuticals recommends this go after your toner, but before your other skincare products.

Skinceuticals HA Intensifier - in case you didn't know the HA stands for Hyaluronic Acid

Skinceuticals is one of those brands that's a little niche, but has quite the following among skincare devotees, particularly for its CE Ferulic (which is sometimes considered the gold standard in Vitamin C serums). So I was pretty excited about the HA Intensifier, and was hoping that it would also live up to the brand's reputation for good skincare.


Skinceuticals HA Intensifier: A key claim is that the product helps to boost skin's own hyaluronic acid production
I'm sure at this stage, you're curious about so many things - does this serum live up to Skinceuticals' brand reputation? How exactly does a serum boost your skin's own ability to make its own hyaouronic acid, and does the Skinceuticals product do so? So, let's start our review - at the ingredients list!

Natural and DIY Skincare and Chemicals: You Ask, I Answer

Here's my second "You Ask, I Answer" post, where I consolidate some common (and not so common) reader questions. Reader questions aren't a new thing on my blog, and I've written a bunch of posts based on reader questions over time, including some of my personal favourite science-y posts, like my post on parabens, and my post on talc. But I thought it would be nice if I could share some of my reader Q&As with everyone else too!

Today's question on DIY and natural skincare comes from Chelsi:

Chelsi asks:
I want to ask u something. It's so hard for me to get organic and natural skincare that avoids not using harmful chemicals...the fact is there are lots of brands outside there use chemical ingredients... I want to make DIY skincare but I think i don't have enough time to make it while I have to work and after work I am tired and just wanna take a rest..So , do you think it's okay to still using the skincare which still contains chemical ingredients? thx :)

Your question is quite a big hairy one, so I'll just touch on some key topics that you raised:
1. Are chemicals really a problem in skincare?
2. So when should I avoid "chemical" ingredients?
3. Can you actually DIY your own skincare, and if so, is it actually "better" that what's available out there?

Cetaphil's Regulatory Affairs Manager Talks Skincare Routine and Products!

Yes, more skincare questions are answered in today's post! This is part 2 of the post where Cetaphil's Regulatory Affairs Manager answers some skincare question, and busts some skincare myths along the way. And today, we're going to talk about how to simplify skincare routines, what you should do for different skin types, and answer some product questions, including those pertaining to Cetaphil products. As a skincare geek, I always feel like I already know most of the skincare basics, so knowing more about what makes a brand's products different from the other dozens of products on the market definitely excites me!

My view from the Q&A session: Cetaphil's Tracy is helping to answer some questions!

Fortunately, Tracy Chean, Regulatory Affairs Manager at Galderma South East Asia, was very kind to answer all of my (and everyone else's) questions! If you've read the previous post you'll already have some idea of who she is, but in short, she ensures that Cetaphil and other Galderma products comply with strict safety and compliance standards, and is also a licensed pharmacist. She was very friendly and helpful in answering questions at the Cetaphil Experience Workshop, and I really appreciated her broad knowledge of everything from cosmetic regulation to skincare science.


Some of the bloggers during the session - everyone is busy taking notes!
As with the previous post, while the content of the answers is reflective of the information conveyed, it might not be the exact word-for-word answer that Tracy gave, just because I was furiously scribbling down notes during the entire session, and couldn't get down every single word said exactly. However, the gist of each of the answers is accurate. I've also added in some editor's notes (aka my own additional thoughts) here and there to provide supplemental information where appropriate.


A quick photo of one of my notes pages - I'm not kidding when I say I was furiously scribbling down notes!
So without further ado, let's take a look at some common questions about building your skincare routine, and Cetaphil products! If you want to learn more skincare facts, and find out what else went on during the Cetaphil Experience, do check out the Cetaphil Singapore Facebook Page!

Cetaphil's Regulatory Affairs Manager Busts Common Skincare Myths!

In August earlier this year, I had the opportunity to go for the Cetaphil Experience - basically a 3-day trip where I got to learn more about the brand, the philosophy behind their products, and their history in Singapore and in the Southeast Asia region. You might have seen some of the updates on my Snapchat, Twitter, Instagram and so on - and now that I've had a bit more time to settle down after the trip, I've decided to share some of the learnings with you guys!

Tracy Chean, Regulatory Affairs Manager for Southeast Asia at Galderma Singapore, answering some of our questions

As a skincare geek, one of my favourite parts of the trip was the ability to get some burning skincare questions answered, and skincare myths busted by Cetaphil's own Tracy Chean, who is the Regulatory Affairs Manager for Southeast Asia at Galderma Singapore. Tracy ensures that Cetaphil and other Galderma products comply with strict safety and compliance standards, and also manages the Galderma National University of Singapore (NUS) Student Internship Programme. She graduated from NUS with a Bachelor of Science, and has also been a Singapore Licensed Pharmacist since 2010. Above that's a photo of Tracy, looking gorgeous in red! She was very friendly and willing to answer a lot of our questions, no matter how basic or esoteric they were.

Yours truly asking a question at the session

The entire session was 1.5 hours long, and there was a lot of information shared during this session. During this session, Tracy helped to bust some skin myths, answer some questions about cosmetic regulations, and offer advice on a good skincare routine. Since there were quite a number of questions, I've arranged them by topic, rather than just in chronological order, so that it makes more sense to the reader. I've split the post into two - today's post will deal with skincare myths, and the next post will deal with questions on skincare routines and specific product questions.

Also, while the content of the answers is reflective of the information conveyed, it might not be the exact word-for-word answer that Tracy gave, just because I was furiously scribbling down notes during the entire session, and couldn't get down every single word said exactly. The photo below is of my notes pages from the session - you can see how much I was trying to write down! Nevertheless, the gist of each of the answers is accurate. I've also added in some editor's notes (aka my own additional thoughts) here and there to provide supplemental information where appropriate.

That's my notes from the session - 1.5 hours of furious scribbling!

Cetaphil has uploaded lots of videos from the session on the Cetaphil Facebook Page. Where the videos of a particular answer is available, I've also embedded it directly below the answer - so you can hear Tracy in the flesh as well!
