Bubble mask

It doesn't even contain 3-o-ethyl ascorbic acid (uses magnesium ascorbyl phosphate instead), and it's a retinyl palmitate/anti-aging illuminator, not the amino acid/milk protein soothing mask base of the source.

A peel-mask with ascorbyl glucoside and pumice exfoliant, missing the source's key milk protein, oat amino acids, and licorice actives entirely; vitamin C form also differs.

Uses ascorbyl glucoside rather than 3-o-ethyl ascorbic acid, and is an oil/butter-rich emulsion mask with none of the source's amino acid, milk protein, or licorice actives.

This is a soap-based mud cleansing foam with sodium ascorbyl phosphate, not the same vitamin C derivative, and it lacks the film-forming carbomer/protein gel-mask structure entirely.

This is a moisturizing oil/urea-based mask using ascorbyl palmitate, not 3-o-ethyl ascorbic acid, and shares none of the source's protein or licorice actives.
