Question: what is the difference between differin 0.1 and 0.3?
Answer: There were no statistically significant differences between adapalene 0.1% gel and adapalene 0.3% gel for AEs. In the adapalene gel 0.3% group, the most common treatment-related AEs (occurring in more than 5% of the subjects) were skin discomfort and dry skin; the same was reported for adapalene 0.1%.
