Hi Michelle,
Thank you for this helpful analysis of Spray sunscreens. Can you please comment on powder sunscreens and whether these are a viable alternative?

Many thanks!

In reply to Amy. You don't need to avoid any sunscreens during pregnancy - the limits are generally established based on effects on animal fetuses!

Hey Michelle! I recently came across your YT and have absolutely binged your content, just wanted to say thank you!!! I got sucked into clean beauty and my skin is just not happy. I so, so appreciate all of your content ❤️.

We recently moved from UK to Aus so I’ve been watching your videos on sunscreen which have been super helpful. I’m currently pregnant so I’m wondering if it is true (or another fear mongering tactic) to avoid ‘chemical’ sunscreen during pregnancy? If so, would you recommend the Ultra Violette Lean Screen Mineral or the Naked Sundays Collagen Glow 100% Mineral for extremely sensitive, broken barrier, rosacea skin?

😅 I’ve got a big list of specifications at the moment haha. Thank you again!

I always doubt how many droplets can land on my face and finally you had tested it well Michelle. ^ ^

In reply to Peter. I think it gives more benefits than just vitamin D, but the risk isn't always worth it - I did a post about this back in 2016, but I should do an updated one on the new Australian guidelines. I'm going to a sunscreen conference soon where some of the authors of the guidelines will be presenting (one of the authors actually invited me to do a plenary talk there), so probably after that!

In reply to Lena. I can think of a method of doing it (and for benzoyl peroxide), but it already seems a lot harder than what I expected the sunscreen spray test to be, so it's probably going to turn out to be way, way harder in reality! I might try some preliminary tests soon to see if it's feasible at all, but I don't have high hopes haha...

I knew it! I’ve long suspected that spraying sunscreen was really inefficient, especially outside on a windy day. I’ve tried to counter this by spraying SPF onto my hand first and then applying to to my face, which always feels like having the spray nozzle is pointless. Even with this method there is still spray that tends to go elsewhere, either on other parts of my hand or missing my hand all together. Thanks to your (incredibly!) thorough research we can now say conclusively that the disadvantages of the spray massively outweigh the advantages.

Or I guess my first question should have been, is hypochlorous acid even a good ingredient? Usually, we use antioxidants to fight reactive oxygen species so I wonder how actually applying an ROS can be beneficial to the skin. Would it be pro-aging?

Gotta love your dedication to research and finding proper research methods. Already watched the video but it’s nice to also have it written out.

Do you think it would be possible to create a test on how long one should wait before continuing with the skincare routine after using hypochlorous acid? It’s such a popular and apparently effective ingredient but since it’s an oxidant I worry about it deactivating actives like vitamin C, retinoids and antioxidants.

I really like that you conduct experiments 🙂
