The crease under my belly and before my fupa get ref, sore and sometimes break open..was wondering what the best product is to help with that
There are a lot of options out there. It's not so much about any product being the best so much as the best for you.
I have thick thighs, so I know how important it is it keep things clean and dry. There are anti-chafing sticks, powder, diaper rash cream, and more. Some people prefer to keep their pant under their bellies for this very reason.
Another thing you need to do is keep the area clean, dry, and moisturized. What I like to do is wash the area with my face cleanser. Hibacleans is another good one if you are dealing with broken skin. Pat the area dry with a towel, and follow up with an oil or butter of your choice. I like to use raw Shea butter oil tea tree oil.
IMPORTANT
Do not use straight tea tree oil. You will irritate your skin. Always have it mixed with a carrier oil. You can either do this yourself or buy something pre-formulated. I like to used the kind from Hollywood Beauty.
