You use controversial "carrageenan" and "carbomer" in this product. How do I know this is safe for my skin?

These are usually included in most cosmetic, bath and beauty products out there. The role they play in a formula is basically to help deliver the other ingredients into the skin, hair, injury, etc, by being a soluble (breaks down in water). Some strains have their own long list issues and are very often the cause of skin and hair conditions; and there are lots of types out there for sure. Instead of using those cheaper, harmful ingredients, we only use ingredients that meet our high standards of quality in our formula, safety for our customers, and agree with our commitment to the environment.
