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.

Curious to see if it works
Size: 60ml
I’ve started a whole new shaving routine and decided to give this stuff a shot, with what I’ve used thus far I can say the smell is pleasant if you enjoy earthy and floral scents. It has a perfumey scent, but the oil itself left my skin glowing and soft. I’m anxious to continue use!
