Where they part company
Mad About Skin calls Neutrogena Collagen Bank Vitamin C Serum skip. 208SkinDoc calls it approved. Two experts, one product, takes about 2 weeks apart, and opposite conclusions. Their own words are above; we are not going to tell you which of them is right.
What the whole panel says
These two are not the only voices on Neutrogena Collagen Bank Vitamin C Serum. Across every independent expert take we hold, it carries a Guru Score of 72% from 5 experts, which is the share of them who approved it. The other 3 experts we hold takes from are counted in it too.

Why we only pair takes from the same month
A formula gets reworked, a price moves, and a product people loved in one year is not the product they are handed in the next. Two takes far apart in time can look like a disagreement when they are really a description of a product that changed. So a face-off only pairs experts whose videos went up within a month of each other, and neither take here is sponsored.
