how to use jaiphal on face - #24591

I am really trying to figure out how to use jaiphal on face but I feel a bit lost. A couple of weeks ago, I went to this Ayurvedic shop, and the owner said jaiphal could work wonders for my skin which has been pretty dull and uneven lately. I've read it can help brighten the complexion, but now I'm second-guessing myself. I even bought a small jar of jaiphal powder, but I'm not sure what to do with it! Should I mix it with water or some kind of oil? Like, I saw one recipe suggested combining it with coconut oil, but then I got paranoid about breakouts since my skin is so sensitive these days. Also, how long should I keep it on my face? I'm scared of irritation. And I heard you shouldn’t mix it with certain things, but I’m not clear on what those are. If anyone out there has actual experience on how to use jaiphal on face, like what worked for them and what didn’t, I’d be super grateful for some guidance! Thank you!
