I can't tell you how long I had to go without using a deodorant due to my sensitive, allergic skin! It is a delicate area of the body anyway without having any further sensitivity so I had to be careful in my choices.
After doing considerable research I eventually found one I CAN use safely that do not irritate or bring me out in a rash.I still do find that for me at least it is not wise to put on deodorant very soon after shaving the underarm area - I tend to leave it a few hours or overnight.
I do have very sensitive skin though so you may not have that need. Get to know your own skin.
I am currently using Green People Scent Free Deodorant and it works very well, does not leave any residue, no body odour, no harsh chemicals, no parabens, and no scent and best of all does not irritate my skin.
This will not stop you from the body's natural process of sweating but will stop you from smelling !
I use the roll on and you do need to wait a little while for it to dry but its not a problem. I find that of all the Deodorants I have tried this is the best one for me.
The Green People Deodorants are free from any harsh chemicals and have a full listing of ingredients on the website and the scent free range is especially useful if you are allergic to perfumes.
If you like to wear perfume but do not want your deodorant competing with your fragrance a scent free option s a good choice for the delicate underarm area.
I have recently tried other options in the Green People range and I am finding that now I can also use the Rosemary deodorant. This is a good step forward for me for those days when I want a little delicate scent.
There is also a men's range in black containers, but really anyone can use them. I amazingly have been able to use their GREEN PEOPLE Stay Cool Deodorant with mint and prebiotics which is good I find especially for summer.
The range is aluminium free and is not tested on animals which is important to me as well. I highly recommend The Green People range of deodorants and am so glad that I discovered them.
