[Product Question] What are the differences between Adapalene (Differin) and Tretinoin?

Beauty Tips For Body Care
This may be a dumb question, but I'm genuinely curious. What is the difference between the retinoids Tretinoin and Adapalene, aside from strength?I see Differin recommended on her specifically for acne, but I see Tret recommended for acne AND anti-aging/wrinkles/lines.I've been using Adapalene .3% for 4 months and have had amazing results for my breakouts. No effect on lines, however, and was wondering of Tretinoin might be a better option to prevent and reduce wrinkles.Tl;dr: Tretinoin vs. Differin on acne and anti-aging benefits, which one is better?
