Estimate what's really in a lotion, cream, balm or serum from its printed ingredient list (INCI). Finds the likely '1% line' (ingredients above it must be listed by amount under US FDA 21 CFR 701.3 and EU rules), gives a rough percentage range for each ingredient above the line, says what each ingredient does, and adds neutral notes on ingredients people with sensitive or eczema-prone skin often avoid (fragrance, essential oils, some preservatives). Estimates come from label order and typical use levels; they are not lab measurements. Same engine as https://corium21.com/pages/ingredient-label-decoder.
The ingredient list exactly as printed on the label, comma separated. A pasted 'Ingredients:' heading, 'May contain' section or Drug Facts panel is fine.
cream = lotion or cream (default); rich = rich cream, body butter or balm; light = light lotion, gel-cream or serum. Adjusts typical use levels.
