The most detailed article I've ever read about sun protection! Thank you :) Do you have an opinion about the compact sun protection powders by Uriage and Bioderma? They don't state the percentage of the titanium dioxide and zinc oxide so I can't I can't use the sunscreen simulator :/

Thank you for reading! Unfortunately I have not tried those, but my experience with other compact spf powders is that it starts looking cakey if I apply too much, but if I don't I worry if I'm getting enough protection. So I'm ended up just using mine for touch up!

What’s the general UVA & UVB wavelengths covered by UPF 50+ clothing brands, such as from Coolibar & Baleaf? PPD rating for UPF 50+ clothing? Have you heard of/tried the Skin Aqua Rohto Newer Model Super Moisture Gel Pump 140g - SPF50+/PA++++, and any information you might have about it’s PPD rating and if it’s PA rating has been tested? Tysm for your time and stay safe :)

Hi there. Concerning the UVB wavelengths around 290-320nm & the UVA UVA are long-spectrum rays with wavelengths from 320-400 nm, what UVA & UVB ranges do most UPF 50+ clothing brands cover, in terms of the wavelengths of UVA & UVB? Have you had any experience or any thoughts with an Australian UPF clothing brand known as Coolibar or Baleaf? Their on Amazon, and while Coolibar is a little more pricey, it has protected my skin very well :). One final question for you (sorry I’m so just very passionate about proper sun protection and all of that just like you, so I’m always trying to learn as much as possible in order to be as sun smart as possible, indoors & outdoors), what are your thoughts on the Skin Aqua Rohto Newer Model Super Moisture Gel Pump 140g - SPF50+/PA++++, and anything you might know more specifically about it’s PA & PPD rating? Thanks so much for your time, really enjoyed reading your post, & most importantly - stay safe :)

Hi Jeffrey, I'm actually not too familiar with sun protection clothing but after a quick search it seems they use a different measurement - UPF, which measures both UVA and UVB penetration rates. I also haven't tried the new Skin Aqua sunscreen, but according to its product description it's meant for everyday normal activities. So if you plan to be outdoors all day, I'd definitely use something else instead! Hope this helps and thanks for reading!

Very helpful post but how do we use the sunscreen simulator when most sunscreens don’t mention the percentage of the uv filters?

US sunscreens are required to list the filters %, and for other brands you can check cosdna, sometimes people list the % there. You can also email the brand to see if they'll provide the info, but you're right, without the % you won't be able to use the simulator.

Hi Jenny,

Thanks for writing this guide on sunscreens! I'm in Taipei right now and as someone who absolutely does not sweat gracefully like most Asians – I've been drenched in sweat for the last few days with literal beads dripping down my nose – I really need a sport level sunscreen like the Anthelios. Do you know where I can find the Anthelios sunscreens in store? My Shiseido Anessa has let me down – I have definitely tanned to my dismay – and I don't have high hopes for the Biore UV Perfect Milk that I just bought. I haven't seen any though in any of the Watsons, Poyas, or Cosmeds I've been to.

Thanks again for your blog! It's wonderful to find an English-language blog about Taiwanese fashion and beauty.

Hi Justine, thanks for reading my blog and glad you find it helpful! La Roche Posay in Taiwan is kinda weird in that they're sold in pharmacies and clinics only. Their official site has a list of all the stores that carry their products, as well as official online distributors: https://www.lrp.com.tw/Channels/Location Hope this helps!
