Good idea PWAIN.
To start, I'll list ingredients that I am confident have no potential for harm or are my preferred ingredients and invite others to comment.
Starting list:
For the main ingredient (SPF100):
Avobenzone
Octocylene
Oxybenzone
I've chosen these to reach SPF100
Acceptable Inactive Ingredients:
Ascorbic Acid
Aloe Vera leaf juice
Olive Oil
These are pretty harmless
Maybes (seem like harmless ingredients from experience unless otherwise specified but not at this time well known to me):
Disodium EDTA - harmless in small quantities and necessary to be absorbed into the skin?
Cottonseed Oil -
White petrolatum -
What are some things we don't want in our sunscreen? Please share links if you can.
Any products that you find to be particularly gentle on the skin or desirable?
Ingredients for enhancement?
