Yes, cyperus rotundus oil can make facial hair grow back slower, thinner and less noticeable. Use 1 to 2 drops of Bare Oil on the chin, upper lip, jawline or peach fuzz after tweezing, threading, dermaplaning or waxing, morning and night. It's especially strong where laser is weak: in a randomized clinical study, cyperus rotundus oil was significantly better than laser on white hair.
Facial hair in women is common, and so is the frustration
A few dark hairs on the chin that come back every week. A shadow on the upper lip. Fine peach fuzz that catches the light and your makeup. Light or gray hairs that laser simply can't see. If that's you, you're not alone, and you're probably tired of tweezers, threading appointments and bleach.
Facial hair often changes with hormones, for example around menopause. If your facial hair is increasing suddenly or quickly, talk to your doctor first, as it can be a sign of a condition like PCOS. For everyday unwanted facial hair, there's a gentler daily option.
Chin hairs: stop the weekly tweezing
Chin hairs are usually coarser and darker than the rest of your facial hair, and they grow back fast. Tweezing removes them from the root, which is the perfect moment to apply cyperus rotundus oil.
"I use it for those annoying chin hairs that I had to constantly be plucking out, it has slowed them down they seem thinner now as well"
The chin routine
- Tweeze or thread as usual.
- Wash with a gentle cleanser and pat dry.
- Apply 1 to 2 drops of Bare Oil to the chin and massage in.
- Repeat morning and night, every day, even when there's nothing to tweeze.
Peach fuzz and blonde facial hair
Fine, light hair (vellus hair) is everywhere on the face. Dermaplaning removes it beautifully, but it's back in days. And because it's light, laser usually isn't an option.
That's where cyperus rotundus oil stands out. In the 2014 randomized study, the oil showed no significant difference from an Alexandrite laser overall, and was significantly better than laser on white hair.
"i have softer skin no doubt and thin hairs, works even on the blonde hairs i had forever on my face"
Upper lip and the "shadow"
The upper lip is small, sensitive and very visible. Wax and threading work, but the shadow comes back. Customers use Bare Oil between sessions to keep it lighter and slower. Bare Oil's listing names lip and face among its recommended uses.
"... laser is out of my budget atm but kept seeing vids about this oil and it's worked incredible, my facial hair has thinned out so much and its slower to even come back i dont get that gray shadow anymore"

The science: why light facial hair is the sweet spot
In a randomized clinical study published in Aesthetic Surgery Journal (2014), 65 people with unwanted underarm hair were assigned to topical cyperus rotundus oil, saline, or an Alexandrite laser (GentleLase). Results were judged three ways: hair counts, independent professionals and patient self-assessment.
"Cyperus rotundus essential oil is as effective as the Alexandrite laser for decreasing the growth of axillary hair (both dark and white)."Study conclusion · Aesthetic Surgery Journal, 2014 · PubMed 24408514
Follow-up randomized trials: 153 people (PubMed 34618367) and 308 people (PubMed 35290702) both recorded significantly reduced hair growth in the cyperus rotundus oil groups; a 153-person trial after laser favored the oil for pain relief (PubMed 34132024).

"it actually does work I never expected that from an oil, smells nice too its more of a natural scent"
"I swear the worst part of shaving was always the waiting for it to grow back 😭 Started putting this on after my shaves and I've noticed my regrowth is way less noticeable. It takes longer to show up and the hairs feel much finer now. The oil itself is really lightweight too, so I actually enjoy using it instead of forcing myself to remember."

Facial hair and cyperus rotundus oil: your questions, answered
Does cyperus rotundus oil work on facial hair?
Yes. Customers use Bare Oil on chin hairs, upper lip, jawline and peach fuzz, and describe hair that grows back slower and thinner. Bare Oil's listing names face and lip among its recommended uses. In the 2014 randomized study on underarm hair, cyperus rotundus oil matched an Alexandrite laser overall.
Will it work on blonde, white or gray facial hair?
That's where it shines. Laser targets pigment, so it usually can't treat light hair. In the 2014 study, cyperus rotundus oil was significantly better than laser on white hair, on all three measures.
Can I use it with plucking, threading or dermaplaning?
Yes. Remove hair your usual way, then apply 1 to 2 drops to clean, dry skin. After threading or waxing, wait until any redness has calmed.
Will it clog my pores or cause breakouts?
Bare Oil is a lightweight formula with jojoba oil, which moisturizes without clogging pores. Use only 1 to 2 drops on the face and patch test first. If you're acne-prone, start once a day.
Is it safe to use near my eyes?
No. Keep it away from eyes, eyelids and brows. If it gets in your eyes, rinse with water.
Why am I getting more chin hairs?
Hormone changes are a common reason, for example around menopause. Sudden or rapidly increasing facial hair can be a sign of a medical condition such as PCOS, so talk to your doctor. Bare Oil is a cosmetic and does not treat medical conditions.
Can I use it under makeup?
Yes. Apply in the morning, let it absorb for a few minutes, then apply makeup as usual.
