Write to [email protected] — a human reads everything, though replies take a few days when volume is high.

What to write for

• Feedback: what confused you, what broke, what would help.
• Ingredient correction: the ingredient, what you believe is wrong, and a source if you have one (label photo, paper, monograph).
• Brand formula update: the product, what changed on the label, and where you saw it.
• Privacy requests: access or deletion questions — see the privacy policy.

What happens next

Corrections are researched against primary sources before anything changes; accepted ones land in the dataset and are logged in the public changelog, per the editorial policy. We cannot answer personal medical questions — for those, please see a dermatologist (see themedical disclaimer).
