Beyond50Skin has tested 39 serums and has been largely positive, approving 30 and earning a Guru Score of 77%. She marked 5 as mixed takes and skipped 4. She named three of those serums outright category winners.
What does Beyond50Skin recommend in serums?
Hydration and absorption are the through-line in her approving takes. She has praised serums that actually soak into the skin rather than sitting on top, and she mentions that quality more than once. She also cares about how vitamin C serums feel in use, and praised SkinCeuticals C E Ferulic for having no off-putting smell and no greasy finish. Speed of visible results is the other pattern, and she noted that the Dr. Idriss De-Puffer, one of her three named category winners, calmed her redness in about five minutes.
In their words
"The vitamin C [...] by Skinceuticals is a little bit of a boost in price because it has the additional DNA repair enzymes. It's fantastic. It contains L-ascorbic acid, which is the gold standard for vitamin C formulas, and it also contains CE Ferulic, and it doesn't have that funky smell or that greasy feel that you get with some vitamin C's. [...] This is definitely going to be on my repurchase list."
"I gave it a five out of five. [...] At the end of the day, I couldn't believe it. [...] It looked just as beautiful midday as it did at the end of the day. Super shocked. Absolutely love this new find."
"The last step in my evening skincare routine is usually a light layer of castor oil. [...] Queen of Thrones is my absolute favorite. And I've been using this now for about a year. [...] I have extremely dry skin and I have found that most body oils just sit on top of my skin [...] and transfer to my sheets. This actually soaks in. So, love this."
"I've been using this day and night. I use it over my lip to help reduce the look of those creases and lines over my lip. I also use it on my lips overnight and I've also been using a little bit in the morning to hydrate my lips. This has been an absolute favorite find of mine."
"This is one that is super hydrating. It also helps work on anti-pigmentation with the digosal galic acid and, I believe, tranexamic acid."
"The depuffer by Dr. Idriss is my top pick. It has a roller. You can keep it in the fridge for a cooling effect, but if you have redness, hot flashes, this is amazing for reducing redness quickly. It usually takes my skin about 5 minutes to kind of calm down."

What has Beyond50Skin skipped in serums?
She skipped four serums, and in each case the reason was practical. Tatcha Serum Stick was a format issue: she finds solid skincare products simply do not work for her skin. The Ordinary Multi-Peptide + Hyaluronic Acid Serum made her scalp greasy with her hair care routine, Mad About Skin Skin Perfecting Peptide Serum sat too heavy to dry down in warm weather, and DRMTLGY Needleless Growth Factor Serum did not show visible results or deliver the hydration she was looking for.
"I've decided that solid skincare just doesn't work for me. The solid stick by Tatcha, this is their Serum Stick. It's hard to get out. And it's just not pretty at all. It's not pretty on my lips. It's not pretty on my cheeks. Super disappointing."
"Another product that I use is by The Ordinary. I found this difficult to use because it has peptides, it has humectants, I just found it didn't go with my hair care routine because it made my scalp a little bit too greasy. I tried using less product and it really didn't help that much. So, I've kind of only gone through maybe a fourth of this bottle. I don't think that I'm going to finish it."
"The Mad About Skin has an amazing ingredient deck, but it just didn't work for me for summer time. [...] The ingredient deck is beautiful and it's a wonderfully hydrating serum, but [...] it sits a little bit heavier on the skin. In the warmer days of the summer I was having trouble getting this to dry down. I think it's going to be better suited for dry skin and in the winter time."
"That is one product that just doesn't work for me. [...] I personally just didn't see that much of a difference in my skin when I used it. And also, it just wasn't quite hydrating enough for me."
What should you take from Beyond50Skin's picks?
Beyond50Skin is generous with serums but specific about what earns her enthusiasm. She keeps coming back to products that hydrate deeply, absorb cleanly, and show results you can see. Her three named category winners, Remedy Vitamin C Serum, Dr. Idriss De-Puffer, and Queen of Thrones Castor Oil, are the clearest signal of what she would actually reach for again.
