EWG flags hazard, not real-world risk — ratings don't account for how much of an ingredient a product contains. Treat these as things to research, not verdicts. How we score →
How to use
General guidance from this product's category and active ingredients — always follow the directions on the package.
Trust & honesty
The concentrations these actives are typically effective at in research — not a measurement of this product.
L-ascorbic acid is usually used at 5–20% (around 10–15% is common). Above ~20% adds little and tends to irritate more; it also needs a low pH to work.
Ascorbic Acid (Vitamin C)
OTC leave-on AHAs are usually 5–10%. The effect also depends on pH and free-acid value, not the percentage alone.
Lactic Acid
INCI lists don't disclose amounts, and we don't claim to know this product's levels — these are the ranges these ingredients are usually effective at, so you can tell a real formula from "fairy-dusting" a marketed active. How we estimate this.
