Holy grail
[Combination skin, Fitzpatrick 4] Leaving this glowing review because I need this sunscreen to be available forever. I have tried a MYRIAD of tinted mineral sunscreens over the years - Beauty of Joseon, EltaMD, Ultra Violette, Australian Gold, DRMTLGY, Purlisse, and Bliss, to name a few - and I hav...

Disco ball
For those who love a dewy/shiny finish, you're good. But for girls like me who have textured and/or oily skin, this is a big nope. And that's really the only negative. Otherwise, this would be the perfect sunscreen. The medium was a great match for my skin tone, nice thin formula, didn't pill, g...

Light Shade expires 6/2026
It is concerning that the company has been unable to restock the light shade. When I contacted them, they explained that the current inventory comes from a single batch that expires in June 2026 and that they have not yet placed a new manufacturing order. They suggested purchasing one of the darker shades instead; however, as someone with very fair skin, that is not a practical solution. Skin tones can vary significantly, and consumers cannot simply substitute a darker shade and expect it to be suitable for everyone.
Blends beautifully :)
I've been looking for a tinted face moisturizer for a while. I like the richness of this serum and how easily it blends into my skin. It gives my skin a beautiful glow too.
Superb all around
I have been kind of sunscreen obsessed, for years, since a dermatologist told me to wear good sunscreen daily, even on cloudy days and I have followed this advice for decades. I came across Undefined maybe a year ago. It has become my go-to every morning, after I brush my teeth. I love the consistency, the quality, how it makes my skin look nourished. I typically don't wear foundation, but when I do, I wait 15 mins, to let the sunscreen do its thing and then I add foundation which stays nicely without interference from my Undefined sunscreen. Undefined is a gem. I hope it never gets discontinued because I am a believer.
Love R & R Sun Serum
What a blessing that I "accidentally" the undefined R & R sun serum. I have the tinted and recently bought the untinted/ cream sun serum to use as my sunblock. I love how it gives me protects me not only from the sun but also is healthy for my skin by having natural ingredients. Thank you for the creator (s) of these products!
Love this stuff!
The is pretty dang close to my holy grail sunscreen! I love how light and moisturizing it feels. I can use it both in the warmer humid months and the cooler dryer months. Great product!
