After like 3 weeks, I realized I wasn't shaving nearly as much anymore. My underarms and bikini line used to get stubbly again so fast, like within a day or two, and my legs were always irritated from shaving all the time. But since I started using this serum, the hair grows back way slower and my skin just feels so much smoother. It sinks in really fast too, which I love, because it doesn't leave that greasy feeling. It's honestly made getting ready for beach days or weekend trips so much easier haha.

How Cyperus Rotundus Serum Works
Cyperus Rotundus is an ancient Egyptian botanical clinically proven to progressively weaken hair follicles by targeting the DHT hair growth signal at the follicle, so they produce thinner, slower, and sparser regrowth until they can’t produce hair anymore.
How To Use
1.
Remove unwanted hair by your removal method of choice (shaving, waxing, plucking)
2.
Apply 3-5 drops of serum to clean, dry skin
3.
Massage until fully absorbed
4.
Repeat steps 2. & 3. twice daily for best results
Why remove hair first?
The serum doesn't remove hair temporarily — it works at the follicle to reduce regrowth over time. You remove the hair you have now, and with consistent use, there's less and less coming back, until there's barely any regrowth at all.
Safe & Suitable Even For Sensitive Skin
Our serum is safe to use for sensitive and irritated skin. Hyaluronic Acid and Arginine nourish and soothe the skin, while Cyperus Rotundus Root Extract works locally to weaken hair follicles by blocking DHT without interfering with your hormonal balance, making it safe whether your unwanted hair is hormonal (PCOS, menopause) or simply the hair you were born with.
Designed for all hairs across the body
Whether it's thick and coarse, curly, or soft peach fuzz. Cyperus Rotundus works anywhere on the body by targeting the hair follicle to reduce the hair growth signal, rather than targeting hair color or hair type.
60-Day Money-Back Guarantee
We’re so confident in this formula that we offer a 60-day money-back guarantee—if you don’t see amazing results, just send it back and we’ll provide a refund!

How It Works
Absorb & Target
Cyperus Rotundus extract is absorbed to the follicle level of the skin. It then stops the growth signals around the hair follicles.
Weaken & Thin
Without the growth signals, hair follicles weaken, resulting in slower growth and thinner, weaker hairs, making them less visible over time until they stop growing completely.
Soothe & Protect
Hyaluronic Acid and Arginine deeply moisturize, soothe and protect the skin while healing any irritation from previous hair removal methods.

Why remove hair first?
The serum doesn't remove hair temporarily — it works at the follicle to reduce regrowth over time. You remove the hair you have now, and with consistent use, there's less and less coming back, until there's barely any regrowth at all.
When Can I Expect To See Results?
Most users notice slower and thinner regrowth in as little as 2–3 weeks of consistent use. With continuous use (over 60-90 days), most customers report a dramatic reduction in hair growth that lasts even after they stop using the serum. That's exactly why we recommend starting with a 2-3 month supply.
What Areas Is the Serum Safe to Use?
Our serum is safe and effective on all external body areas including face, underarms, bikini area, legs, arms and more.
Are There Any Side Effects?
The serum is gentle and safe to use, even on sensitive skin. There are no known or reported side effects.
Is There A Money-Back Guarantee?
Yes, we’re so confident in this formula that we offer a 60-day money-back guarantee - if you don’t see amazing results, just send it back and we’llprovide a refund!
Does it work on light/blonde/white/grey hair?
Yes! Unlike laser hair removal, which only works on dark hair, Cyperus Rotundus targets the hair follicle's growth mechanism rather than the hair's pigment. This makes it the ideal solution for all hair colors.
How long does one bottle last?
One bottle usually lasts up to 4 weeks. We always recommend starting with 3 bottles (3-month supply) as 60-90 days of consistent use is when the results really solidify and persist even when you are not using the serum.
How to incorporate the serum into an existing skincare routine?
It's best to apply the serum on clean skin after cleansing. If you have additional skincare steps in your routine, we recommend allowing the serum to fully absorb before applying your next product. This helps ensure the serum stays concentrated on the targeted areas and isn’t spread out or diluted by subsequent treatments.
Alternatively, since our serum is designed to be applied only to specific areas of concern, you can also use it as the final step in your routine if that works better for you.
One thing to note is that layering products can slightly reduce effectiveness, but we still recommend using the serum twice daily. Many of our customers have seen great results using both methods of application, so you can choose what fits best into your routine.
Will the hair grow back if I stop using the serum?
Cyperus Rotundus Serum does not cause dependency. Once the desired results are achieved, most customers switch to using the serum just a few times a week for maintenance. If you stop using it completely, hair won’t suddenly grow back the way it used to. However, over a longer period of time, you may notice some regrowth gradually returning because our serum works locally (only on the area where it’s applied) to not interfere with your body’s natural hormones or processes. Many of our customers love that it gives them flexibility without locking them into daily use after the desired results are achieved.
How does the Cyperus Rotundus serum actually work?
Cyperus Rotundus is an ancient Egyptian botanical clinically proven to progressively weaken hair follicles, so they produce thinner, slower, and sparser regrowth until they can’t produce hair anymore.
Does it impact my hormones and endocrine system?
It does not. The serum works locally on the applied area and does not enter the bloodstream or have any impact on your hormones and endocrine system.
