I love Retin-A cream. So which is best for skin rejuvenation (wrinkles, tone), the strongest at 0.1% or 0.05%? I recently read that the strongest dose (0.1%) is ONLY for acne. I don't have pimple issues. Does that mean it won't also work for wrinkles? Darn...I've been using the highest dose for anti-aging. Do I return to the lower dose of 0.05% or stick with the 0.1% for maximum results. I believe the former studies were using the 0.05% for wrinkle research. Please advise. XOXO
