It all began because of COVID; bumps appeared on my scalp that became sore and unexplainable  skin rashes, and our grandbaby’s eczema. We gradually reduced products that contained harmful toxic chemicals such as Aluminum, Propylene Glycol, Parabens, just to name a few found in so many common products to include deodorants. If you used Propylene glycol every day, this chemical can cause damage to your central nervous system, heart and liver. It is also shown to irritate skin, especially if you have sensitive skin. Propylene glycol can be harmful as small a percentage as 2%; deodorants generally have a high dose of 50% propylene glycol.
