How to use Beauty of Joseon Relief Sun: Rice + Probiotics SPF 50+

Sunscreen goes on as the last step in your morning routine, and if your skin is more on the normal to oily side, this SPF will probably be enough on its own without the need of a dedicated moisturizer. Applying the recommended amount is no problem as it sinks in completely, it never did pill on me and it is comfortable for reapplying throughout the day as well.

Yes, it adds more dew to the skin than I personally like, but you need to keep in mind that I grew up in the 80s when matte skin was all the rage – you lot with your preference for glow will most likely love it.

Don’t be fooled, if you really apply it liberally, it will take up to a minute until it does fully sink in, but after that no stickiness, no film, just plump and hydrated skin.

The main UV filters used are Uvinul A plus and Tinosorb S, and to support the skin calming and brightening claims you will find Niacinamide, several fermented ingredients and plant extracts like Green Tea and Ginseng Root Extract, all things often found in Korean Beauty products. Glycerin is used as the main humectant.

Is the claimed SPF 50+ valid?

Uvinul A plus and Tinosorb S are modern chemical filters that provide broad spectrum protection. The first thing I do when testing a new sunscreen is that I go to the BASF sunscreen calculator and see how the filters used perform on a very basic level. When doing that, both filters don’t add up to a SPF 50, but instead get to around 36, but with amazing UVA protection. As the filters used don’t tell you the whole story, the formulation plays a huge role too, this is only half of the story. Beauty of Joseon uses Dibutyl Adipate for example, an emollient working especially well in helping to solubilize UV filters, which might have an effect on the protection reached by the finished formula.
The next thing I did was reach out to the brand and ask about their testing methods, and here is what I learned: This sunscreen was tested in two different labs, once in Korea and once in Spain. That alone is reassuring, as sunscreen testing is complicated and the more test results you get, the better your chances to get it right. The SPF testing in Spain was done in Summer 2021 according to Standard ISO24444 and Cosmetics Europe Guidelines 2006, which means in vivo testing on healthy volunteers, and suggests an SPF of 63,1 (+/- 0,6). Now two aren’t three tests and there is still room for error, but I feel comfortable about having adequate sun protection when wearing it, especially as the texture makes it easy to apply a generous amount.

Just remember, putting on SPF is always only part of sun smart behavior and never an excuse to spend hours in the midday sun!


Does it live up to its claims?


It contains calming and brightening ingredients, is a chemical sunscreen and never irritates my skin.


How does it compare to…


Biore UV Aqua Rich Watery Essence SPF 50+ PA++++
Biore UV Aqua Rich Watery Essence SPF 50+ PA++++


Bioré UV Aqua Rich Essence

A Japanese formula, a tad more lightweight than this one, and using two additional filters, Octinoxate and Uvinul T 150, which both add protection in the UVB spectrum. It does contain fragrance and alcohol, which I don’t mind, but might be a problem if you are sensitive to these. While I prefer Bioré in the summer, Beauty of Joseon is my favorite during the winter months.

Would I repurchase and which skin types do I recommend Beauty of Joseon Relief Sun: Rice + Probiotics SPF 50+ to?

I already have two more tubes of this sunscreen stacked up that will see me through early spring and, depending how quickly it will heat up here, early summer as well. While very oily skins might find it too hydrating, I think everyone else will love this formula as much as I do, and the carefully chosen filters make it a great option even for sensitive skins usually reacting to chemical sunscreens.
