Xanthan gum

1. Skin hydration: A study published in the International Journal of Cosmetic Science found that a cream containing xanthan gum was able to increase skin hydration and reduce transepidermal water loss in healthy volunteers.

2. Skin smoothness: Another study published in the Journal of Cosmetic Science investigated the moisturising effects of a gel containing xanthan gum and found that it improved skin hydration and smoothness.

3. Hydration: A review article published in the Journal Molecules discussed the potential of xanthan gum as a natural moisturiser due to its ability to form a gel-like layer on the skin that can help prevent water loss.
