Confidence: medium · v2026.09.3
This assessment is read from the ingredient list and is not medical advice. It makes no promise about acne. Individual skin reactions vary.
Read how we classify productsDryingness 68/100 — strongly drying. The reading comes from the ingredient list and its order, not from a measurement. The largest additions: Sodium Laureth Sulfate (position 2), Sodium Lauryl Sulfate (position 6), Sodium Chloride (position 7). Pulling the score down: Guar Hydroxypropyltrimonium Chloride (position 12), Glycerin (position 27).
Computed from the ingredient list · v2026.08.1
The number is computed from the declared ingredient list and its order. A label does not state concentrations, so this is a reading of the formula — not a prediction of how the product feels in use.
How the dryingness index is calculatedThe order is the manufacturer's own and follows concentration down to the one percent mark. Underlined names are flagged by our criteria. Names with a dotted underline open a short note on what the ingredient does in the formula.
