Conditioner, its super moisturizing
I use this stuff called Coochy Cream. It's AMAZING. I have super sensitive skin as well. I always splurge on a nice sensitive skin razor. If you can't find or don't want to buy Coochy Cream, try conditioner. I also sometimes buy this cream at Walgreens or Wal-Mart called Bump Stopper. It's to prevent razor burn on men's faces, but it's not medicated like Bikini Zone, it's way cheaper, and it works better IMO. And I would buy a bikini trimmer, or a razor with one attached.
Or try baby oil and then shave. I also use a men's razor they seem to work better
I use to shave with a really moisturizing lotion when I was in my teens, I loved how silky it left my legs, maybe you should give it a try
I use aveeno sensitive and a good razor but for my legs and pitts I use intuition sensitive I'm pretty sensitive but these work for me
I use veet it's like nair but so much better I break out with nair but I love veet and it gets it all and very smooth also made for sensitive places!!
Have you never used the soap you wash with? That's what I used to do all the time. You gotta get it to lather real good but it works.
I use body wash on a rag and get it real soapy. I also do it while I'm in the shower so it stays wet and not dry at all
This may sound a bit odd, but I found deodorant helps. It prevents or helps with razor burn under the arms and so I tried it down below and it works wonders. Same for my legs. No razor burn there either!! Good luck momma!!
Or get a bikini trimmer or use a beard trimmer
Also I don't have a bikini trimmer to use and had a bad experience with getting waxed down there .
