Kiehl's Clearly Corrective Dark Spot Solution vs Garnier SkinActive Fast Bright 30X Vitamin C Serum

Both made by L'Oréal Groupe. Here's how the ingredients actually compare.

Kiehl's and Garnier are both owned by L'Oréal Groupe. When two brands share a parent company, they sometimes develop products with overlapping ingredients, though not always identical formulas. In this case, Garnier's SkinActive Fast Bright 30X Vitamin C Serum shares 50% of its top ingredients with Kiehl's's Clearly Corrective Dark Spot Solution, at roughly $16 compared to $85. Whether that overlap is enough to make the switch is up to you — this page exists so you can judge the actual formula for yourself instead of guessing.
