Amazing 1000/10 love this
Absolutely love this product can’t recommend it enough. I’m a waxer and tell all my clients about this product to prevent and treat ingrowns. Especially when there’s inflammation (red and painful). I have acne prone skin triggered by dairy/gluten and I use this after my Brazilian wax, on my face, my back and anywhere where I’m breaking out. The ingredients are great and not harsh on the skin. I’ve also been noticing my bikini hyperpigmentation slowly getting lighter too!

Does what it needs to do…
Tried to wax myself (ouch, I know). But I think this stuff actually worked. I know the hair cycle is like 8 weeks or so, so I got one cycle in and less ingrown hairs for sure. I love, love the easy of use and how you can just roll it on and don’t need a cotton pad or something.

Works but expensive
Works on black hair and skin well. Apply when you feel the itch and that's it. My only issue is it's expensive. 26 is higher than others with similar ingredients.

Worked till it didn't
Worked really well the first 3-4 months. Afterwards, it was not as effective on my skin. I still suffer from these ingrowns even if I use this daily.
