"Bikini line darkening has bothered me for years and nothing ever really touched it. I've been using this between waxes for about 3 weeks and it's noticeably lighter now. Doesn't sting going on or smell strong either, which was the main selling points for me."
Kaitlyn, 45★★★★★
"I came across this traditional oil that's meant to slow hair growth and was honestly doubtful at first because I've tried so many things with zero results. After using it consistently for two months, the difference is unbelievable. I now shave my legs maybe twice a month instead of every single day."
Jade, 48★★★★★
"I used to spend so much time each week managing unwanted body hair and it honestly drained me. I've been using this for around ten weeks now, and I can go weeks without needing to touch the areas I used to have to take care of every single day. My mornings feel like mine again, instead of being rushed in the bathroom."
Our serum is built around Cyperus Rotundus Oil, a clinically studied botanical that inhibits the production of DHT, the primary signal that triggers hair regrowth.
With less DHT being produced, hair follicles receive less stimulation, meaning hair grows back slower and finer with every session.
How do I use it?
After you shave or wax just put 3-4 drops on the area and massage in.
It has to get in the follicle after you remove the hair for it to actually work so just be consistent with it.
Where can I use it?
Face, arms, legs, underarms, bikini line. Use caution near the eyes and mucous membranes, and always patch test before applying to a new area.
How long until I'm not having as much?
After 3-4 weeks you'll notice you're not grabbing the razor as often. First couple weeks the hair might just feel softer but around a month is when you're actually going way longer between shaving.
It's not instant because it's changing what's happening under the skin not just covering it up. The longer you use it the better it gets.
What does it smell like?
Our formula has a light, fresh botanical scent with subtle herbal and woody notes from the natural plant oils.
It's clean and understated rather than heavily perfumed, and the fragrance fades quickly after application.

What Our Customers Are Saying
The bottle is small but it lasts forever. One bottle is getting me through almost 2 months at twice-daily use. I was skeptical when it arrived because it looked so tiny, but you only need 3 or 4 drops at a time so the math actually works.
Melanie, 44, TX
My PCOS chin hairs are 90 percent better after 8 weeks. I was plucking 3 or 4 times before lunch alone and now I check maybe once a week. This is the first thing in 11 years of having PCOS that has actually made a dent.
Sofia, 36, AL
The dropper makes this so easy to use that I actually remember to apply it twice a day. 4 drops, rub it in, done in 30 seconds. I've abandoned so many skincare routines because they were too messy, but the simplicity of this is the reason I've stayed consistent for 8 weeks straight.
Sophie, 34, NH
I've been using this for 6 weeks and my legs have gone from needing a daily shave to maybe once every 2 weeks. For years I felt like I needed to shave morning and evening just to feel presentable. Now I get out of the shower and don't even think about it anymore.
Emma, 40, FL
The ingrowns on my bikini line are basically gone after 4 weeks. I started using this for slower regrowth and the ingrowns disappearing was a complete bonus. The cycle of waxing, picking, scarring was something I thought I just had to live with.
Redness, irritation and inflammation calm immediately after each use. Skin feels softer and more conditioned within the first few applications.

How do I take it?
After you shave or wax - just put 3-4 drops on and rub it in. Takes 30 seconds.
It has to get in the follicle after you remove the hair for it to actually work so just be consistent with it.
How does it actually work?
Cyperus rotundus oil contains flavonoids with anti-androgenic activity — they reduce the hormonal signal that drives hair growth, right at the follicle. With consistent daily use, regrowth gradually comes in finer, softer, and slower.
Where can I use it?
Face, arms, legs, underarms, bikini line. Use caution near the eyes and mucous membranes, and always patch test before applying to a new area.
Will it work on my hair/ skin color?
Yes — unlike laser, which needs pigment and struggles with lighter hair, the studies have found that cyperus rotundus oil worked on white, grey, blonde, and red hair, and across all skin tones.
Is it suitable for sensitive skin?
Yes, our serum is formulated with natural, plant-based ingredients and is free from harsh chemicals.
However, as with any skincare product, patch test a small area first — especially on sensitive skin. If redness or irritation occurs, discontinue and consult a dermatologist.
How long until I'm not shaving as much?
After 3-4 weeks you'll notice you're not grabbing the razor as often. First couple weeks the hair might just feel softer but around a month is when you're actually going way longer between shaving.
It's not instant because it's changing what's happening under the skin not just covering it up. The longer you use it the better it gets.
Is there real science behind this?
Yes. Cyperus Rotundus Oil has been the subject of multiple peer-reviewed clinical trials, including two randomised controlled studies with over 460 combined participants, specifically testing its effects on skin darkening in areas affected by repeated hair removal.
The hair regrowth mechanism is supported by research published in the Aesthetic Surgery Journal, which found Cyperus Rotundus Oil to be as effective as Alexandrite laser treatment for reducing hair regrowth — with no side effects.

I use it everyday and I can’t tell it’s done anything. Still have to shave everyday
Tell me where it is. I am assuming you see it as delivered.
I don’t see it ever leaving CN.
I have one open USPS label sitting in Jamaica, NY with only “Label created.”
Please refund my account or deliver the product.
Thanks
I am 82 years young. I have been tweezing my chin hairs for 40+ years. I use a 15X magnifying make-up mirror and probably tweezed 10-20 hairs each AM and again in the PM and sometimes I tweezed a few more mid-day. I have previously tried every way I know to remove these hairs with no success. I tried Cyperus oil , hopeful, but not really expecting great results. I anticipated if it did work at all it would probably takes months if not a year to really see results as I had so many hairs. It has been a month. I use it several times a day. I now have hardly have any hairs. What is so rewarding is when I do tweeze them, most of the hairs slide right out and I can see the root at the end. Even my ingrown hairs have been greatly reduced. I suspect in another month, if not sooner, I will be hair free. I have been so excited about this that I have inspired at least 20 more people to use it.
Spontaneous beach trip and couldn't believe I didn't stress about body hair. I've been using this for around two months, and the regrowth is so slow that I no longer need to shave every other day. I used to avoid wearing shorts unless I'd just shaved that morning. Now I can go a week or even a little longer, and the hair is still barely noticeable. I actually forgot to bring my razor and it didn't bother me at all.
The bottle is small but it lasts forever. One bottle is getting me through almost 2 months at twice-daily use. I was skeptical when it arrived because it looked so tiny, but you only need 3 or 4 drops at a time so the math actually works.
Thousands of dollars down the drain, just for the doc to tell me "it didn't work because of your skin tone". A friend told me about cyperus rotundus oil and I kick myself every night knowing there was such an easy fix SO much cheaper!
The dropper makes this so easy to use that I actually remember to apply it twice a day. 4 drops, rub it in, done in 30 seconds. I've abandoned so many skincare routines because they were too messy, but the simplicity of this is the reason I've stayed consistent for 8 weeks straight.
I've been using this for about six weeks now, and I haven't felt stressed about my upper lip hair in ages. I used to pluck every morning before work without fail, but now I can go days without even thinking about it. The hair that grows back is noticeably thinner and lighter too.
The endless shave-wax-repeat cycle left me sore and red every time. For years I've been thinking “there has to be a better way.” But I lucked out on this one when I saw an ad for this on my feed. 30 seconds is all it takes for a better result than that whole ruckus before. And it stops those pesky ingrown hairs!

I have PCOS and I've been plucking my chin hairs several times a day since I was 19. It was really affecting me. I've been using this for about 8 weeks, and now I only need to pluck maybe once or twice a week. The hairs are definitely finer, not as coarse, and they grow back so much slower.
My biggest embarrassment was when on holiday my nephew, 8 at the time, loudly shouted, "Auntie's been stung by a jellyfish!" He was pointing at my razor burn. Ever since then, I've tried every cream on the market, but nothing came close to fixing the problem as much as this has. I'm no longer ashamed to wear a bikini in public.
The ingrowns on my bikini line are basically gone after 4 weeks. I started using this for slower regrowth and the ingrowns disappearing was a complete bonus. The cycle of waxing, picking, scarring was something I thought I just had to live with.
I have not seen any improvement yet has been 6 weeks starting to wonder if this stuff is just a gimmick I've been dreaming of stuff like this for years will give it another month
I have no way to contact you to cancel my subscription. I have enough. Someone please contact me LisainLex@gmail.com to confirm cancelation of my subscription please.
Have been using this for about 3 weeks now. Hair still growing on chin and side of mouth, although it seems the hair is less stiff when it grows out. How long will it take for the hair to go away?
