How to use
General guidance from this product's category and active ingredients — always follow the directions on the package.
Trust & honesty
Contains ingredients some choose to avoid or double-check while pregnant or nursing.
Low-strength topical salicylic acid (BHA) is generally considered fine. Caution is usually reserved for high-strength leave-on products and salicylic peels.
This is general information, not medical advice. Pregnancy guidance varies and depends on concentration and your individual situation — always check with your doctor, midwife or pharmacist. How we flag this.
The concentrations these actives are typically effective at in research — not a measurement of this product.
Salicylic acid is OTC-capped at 2%; 0.5–2% is the usual leave-on range. Much below that it acts more as a soothing agent than an exfoliant.
Salicylic Acid
OTC leave-on AHAs are usually 5–10%. The effect also depends on pH and free-acid value, not the percentage alone.
Glycolic 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.
