Talc is not linked to cancer – I wonder if that will affect the court cases
Regenerative beauty: Aussie skin care brand sees luxury potential in horse placenta
There is a challenge with using ingredients that are derived from animal protein, fat, tallow, placenta, etc, and that is transmissible spongiform encephalopathy, also known as TSE when speaking about animals in general, or BSE when speaking about cattle.

Question 1 – Jodi from LA – What is aluminum hydroxide and is it bad if it is in a diaper rash cream?
Aluminum hydroxide is an approved active ingredient to treat diaper rash. It has been approved as safe and effective at a level of up to 5%. This means that the product has gone through medical trials and been proven to be safe & effective. It has an absorbant effect which makes it work. It also has no known skin toxicity so there isn’t anything to worry about.
However, people hear the word “aluminum” and they automatically get scared. There is no reason to be scared but unfortunately, fear-marketers have made people afraid of anything with aluminum, especially antiperspirants and products that are applied to the skin of babies. But these ingredients have been tested and they are safe. I don’t know how to convince people that think otherwise though.
Question 2 – Ben A La Mode (Instagram) – I feel that lip scrubs and masks are all the rage these days, and I am not sure if they have long term benefits. I know that a scrub may make lips feel soft in the moment, but will they make my lips feel and look younger over time? Which ingredients are good for these scrubs and moisturizers to have?
Question 3 Wahde was wondering if we could help with a paper he wanted to write on the impact of cosmetic use and the environment. He says, can you please help by providing info for contributing factors that identify cosmetics as an environmental health problem? And consequences that would arise if the problem is left unsolved or unsolved. Anything will help! Thank you so much!
There are a few ways in which cosmetics impact the environment. They include…
- Chemicals getting into our waterways
- Toxic chemicals
- Air pollution
- Plastic going into landfills
What can consumers do? I don’t really know. I saw the advice that people should make their own cosmetics but this isn’t such a great idea. If you are going to use stuff in your kitchen to make cosmetics they aren’t going to work as well as a standard product. Now, you can buy cosmetic ingredients from home crafter suppliers but if you add up the environmental impact of making it yourself, that’s also not going to be better for the environment. I guess the best that you might be able to do is to buy fewer products and buy from companies that have transparent sustainability programs. And just remember, just because a company says they are environmentally friendly doesn’t automatically mean they are. Cosmetic companies are still in the business to get you to buy more and more product. Even the environmentally friendly ones.
Question 4 – Ravi asks, What are the differences between the mechanism of charcoal and bentonite when they work on your face in cosmetic products?
I couldn’t find any literature about which had more absorbing capacity, but in general, you would use a higher percentage of bentonite in a formulation so I would imagine that you have more absorption capacity. Additionally, I couldn’t find any literature about topical application of charcoal and the adsorption benefits, just the ingestion. However, suppliers of bentonite have done studies about sebum reduction and removal of iron from the skin, while adding beneficial trace minerals like magnesium and silicon.

Funny you mention placenta – recently our NZ Prime Minister had a meeting with Korea and top of their list of more exports from us was sheep placenta. It is VERY popular in skincare amongst the Asian communities so thank you for going in detail about the risks involved in it.
Lab Muffin Beauty Science has a fantastic video on activated charcoal you might be interested in watching. She has a PhD in chemistry. Charcoal is definitely something you don’t want to use on your teeth due to it being abrasive and damaging to the enamel.
Love your show! I hang out for your podcasts every week.
