The BEST thing I’ve tried for my PCOS!
Size: 60ml, Size: 60ml
I was skeptical when I started seeing TikToks of a hair removal oil! Instead of buying the expensive Cyprus oils on there I ran to Amazon to get this!
I have PCOS and grow a short beard and mustache every morning. I’ve been using this for a week and while it doesn’t necessarily remove hair, it SLOWS the growth tremendously! Instead of a full beard, I’m getting a bit of stubble when I wake up.
I would not put myself on blast like this if this oil wasn’t the bomb! 😭
For PCOS girlies looking for facial hair relief, this is a great start.

Be patient with the awful odor and greasy texture because it soaks in and smell dissipates
Size: 60ml
I think i'll edit this review after using consistently for a month or so, but this is my initial impression after 2 uses. First of all, the god awful stench was so off-putting that at first i thought 'there is no way i can use this. It is so disgusting and overbearing'. But it does soak in very quickly and the smell does dissipate if you can just get through it for a bit. (you will not walk around all day smelling awful). So the greasy, oily feeling initially and the awful smell does dissipate and it soaks into the skin beautifully. It is definitely worth continued use to see the results. Just be forewarned if you don't like overbearing bad smells (and i mean it smells like you fell into a pool of insect repellent), you will have to persevere.

ok as part of skin routine, but will take time to see if works
Size: 60ml
I was curious about this product because the idea of a natural product for reducing unwanted hair growth sounded appealing, but my experience was mixed at best. The oil itself feels decent on the skin and didn’t cause irritation for me, which is a plus, especially since it claims to be suitable for all skin types. That said, I did not see dramatic or fast hair-removal results, and it definitely does not work like waxing, shaving, or laser treatments. At most, it seemed like something that might help a little over time with consistent use, but the claims about reducing body hair growth felt stronger than the actual results. If you are buying this expecting a miracle product, you may be disappointed. It may be fine as part of a skincare routine, but I would keep expectations realistic.
