Background
FOLR3, also known as folate receptor gamma, is a member of FRs. Folic acid and its reduced derivatives are transported via two widely expressed transporters, the reduced folate carrier (RFC) and the proton-coupled folate transporter (PCFT), and via a family of glycosyl-phosphatidylinositol (GPI)-anchored receptors with limited expression profiles known as folate receptors (FRs). Folate receptors (FR) are high affinity receptors that transport folate via endocytosis. FOLR3 (Folate Receptor Gamma) is a Protein Coding gene. Diseases associated with FOLR3 include Primary Peritoneal Carcinoma and Choriocarcinoma of The Testis. Among its related pathways are Innate Immune System and Folate metabolism. Gene Ontology (GO) annotations related to this gene include folic acid binding. Mature FOLR3 is a glycosylated protein that contains an imperfect carboxy terminal GPI anchor sequence . A fraction of FOLR3 is GPI-linked to the cell surface, but the majority is released as a secreted protein. Mature human FOLR3 shares 74% and 83% amino acid (aa) sequence identity with FOLR1 and FOLR2, respectively. Orthologs of human FOLR3 have not been described in mouse or rat. A genetic polymorphism generates a truncated isoform that lacks the carboxy terminal 139 aa. FOLR3 is expressed by cells of the myelocyte and B lymphocyte lineage as well as by various carcinomas.

Good for maintaining clean beard lines
I keep my beard trimmed, but I always have to clean up the edges along my neckline to keep it looking neat. Lately, I've been massaging a few drops of this natural oil into my neck on Tuesday mornings right after I finish shaving at the sink. It feels really soothing on freshly shaved skin, kind of acting like a light daily moisturizer.
The bottle is only 1.85 ounces, but you only need a tiny dab to cover a small area so it should last a while. Over the last month, the stubble along my collar line definitely feels softer, and it takes an extra day or two before it starts looking messy again. If you trim your own facial hair and want to stretch out the time between touching up your neck or cheek lines, this is handy to keep by the mirror.

Gentle Oil for After Hair Removal Care
I started using this Cyperus oil after shaving because my skin often feels dry afterward. The texture is lightweight and spreads easily, so I only need a small amount on areas like legs and underarms. I usually apply it after showering, when my skin is clean and dry, then massage it in for a few minutes. The oil feels soothing and gives my skin a softer, more moisturized feeling without being too greasy. It absorbs better than I expected, especially when I use a thin layer. The scent is mild and does not bother me during daily use. For unwanted hair care, I know it is not something that shows a big change overnight, so I use it consistently after hair removal. It has been easy to add into my routine, and I like that it helps calm and moisturize my skin after shaving or waxing.

Absorbs into the skin well and no irritation so far
I bought this Cyperus Rotundus oil to try out, and the 1.85 oz bottle is a good size for me. The oil has a light botanical scent that is pleasant and not too strong. I have applied it a few times and found that it is very easy to use with the included dropper. It absorbs into the skin well and I have noticed no irritation at all, which is important for my daily routine.
The bottle arrived quickly and was packaged securely so there were no leaks. It is a practical addition to my shelf, and the glass container feels solid. This product does exactly what it says on the label and provides a straightforward way to use a natural oil. It is a functional and simple purchase that meets my needs perfectly.

Smooth skin without the post-shave itch
I’ve always had issues with my skin feeling super irritated after I shave my legs, so I started applying this Cyperus Rotundus oil right after hopping out of the shower. The quality of the blend is impressive—it’s got jojoba and almond oil too, so it feels very nourishing rather than just sitting on top of the skin. It absorbs quickly enough that I can put on my leggings and head to the gym without feeling like a greaseball.
The functionality as a hair inhibitor is a nice bonus. I’ve noticed the hair on my shins seems to be coming back a bit softer and less stubbly than before. For a 55 ml bottle, the value for money is solid since you only need a few drops to cover a large area. It’s a great find for anyone who deals with that annoying sandpaper feeling a day after waxing. My roommate even started using it on her arms because it’s fragrance-free and doesn't mess with her perfume.
