If you're new to skincare, start here!
I'd love to see your opinion on EGF serums and creams (e.g., https://www.bioeffect.com/products/egf-serum) and learn your opinion on them, as well as their potential to treat acne scars, wrinkles and stretch marks.
Posting it here because I can't find a better place for it—I would love to see you deep-dive into sunscreens.
Physical vs Chemical (e.g. if any chemical sunscreens should be avoided based on potential hormone disruption).
Your opinion on alcohol in sunscreen.
And. Which brands you recommend for each.
So far I've seen you mention https://www.amazon.com/dp/B002MSN3QQ and https://www.amazon.com/dp/B004W55086/
I'm curious how you can assess the UVA protection of these sunscreens (in Japan they use the PA+ rating. Not sure about Western products).
I've tried this: https://incidecoder.com/products/biore-uv-perfect-face-milk-spf50-pa
And this: https://www.yesstyle.com/en/kao-biore-uv-perfect-milk-spf-50-pa-40ml/info.html/pid.1033325973
The first one was too drying, presumably because of the high amount of ethanol (alcohol).
The second was much better, although I'm still on the fence about the amount of alcohol in it. I'm also starting to *lean* towards pure physical sunscreens, based on the *potential* negative interactions with chemical-based sunscreens (obviously depends on the ingredients).
(this is something I'd love to hear your thoughts on).
Here are the sunscreens I'm currently looking at (all physical):
3/ https://www.amazon.com/dp/B004W55086/ (based on your recommendation)
If you have thoughts on any of them, I'd love to hear them.
Otherwise, I shall patiently wait for your post on sunscreen.
