FAQ

Which ingredients help dark spots in serums?

The ingredients with clinical evidence for dark spots are Ascorbic Acid(B+), Glycolic Acid(B+), Retinol(B+), Tranexamic Acid(B+), Kojic Acid(B+), Niacinamide(B). The serums below carry them near the front of the label (roughly above 1%), ordered by evidence grade and label position.

How is this list ordered?

Grades come from the ingredient studies themselves, checked down to the papers; an ingredient listed past the 1% line counts for less. This is an order of ingredient evidence and label position, not a promise that a product works, and no brand pays to move up.

How much Ascorbic Acid does a product need?

Studies that saw an effect used Ascorbic Acid at 10–20%. Where a label prints no amount, each product page estimates the chance it holds that much from its label position.
