panthenol
what it is
Pro-vitamin B5 — INCI name Panthenol. Once on skin it converts to pantothenic acid, a compound your skin cells already use. We use the D-form, the biologically relevant one.
why we use it
It is a humectant with a conditioning streak: it draws water in, helps skin hold it, and takes the edge off the tight, uncomfortable feeling that follows cleansing or dry weather. It earns its place in both moisturisers at a meaningful level rather than a label-decorating one.
where you'll find it
In feather at 2.00% and in cloud at 2.00%.
evidence
Strong evidence as a humectant; moderate evidence for skin-soothing and barrier support in cosmetic use. We are comfortable with both of those sentences and would not write stronger ones.
safety
Gentle enough to be a fixture of baby-care formulas, with very low irritation rates and no usage restrictions.
