Ingredient analysis and how the ad lines read

Read on 2026-09-22

What is this product?

A silicone and squalane based cream built around 7% panthenol, 10% squalane and four cica ingredients for hydration and barrier care, with a long amino acid block near the end of the list.

What makes it different?

The formula pairs 7% panthenol with 10% squalane, both with printed concentrations, and adds madecassoside, asiaticoside, madecassic acid and asiatic acid at positions 17 to 20. Seventeen amino acids fill positions 36 to 52, giving a moisture factor profile that is unusual for a cream at this tier. Fragrance, essential oils and drying alcohols are all absent from the ingredient list, which suits reactive skin. The clinical numbers on the page are detailed but the testing lab, panel size and protocol are not disclosed.
