A Nair Burn to the skin will last from 5 to 6 days before it heals.
The last time I burned my skin with Nair it took 6 days for the Nair Burn to fully heal but within a few days the Nair Burn started peeling.
The skin where the Nair Burn happened started peeling within a few days of the Nair Burn occurring and then after 6 days the skin healed up.
There may still be a scar where the Nair Burn occurred for awhile and then again the scar may be for life.
But not everyone gets a scar form the Nair Burn but it also depends on how badly the Nair Burned your skin.
When you get a Nair Burn be sure to wash the Nair off with some soap and water and it's best to leave the Nair Burn uncovered to promote healing.
You can apply some lotion to the Nair Burn to help with the skin moisturizing.
