Not medical advice. General education only; it does not replace diagnosis or treatment by a licensed professional. Figures such as 1 mg or 5% are labelled strengths you may see in your country — not a dosing instruction. Consult a board-certified dermatologist before starting, stopping or changing any treatment.
