What is the difference between Renova, Retin-A and Refissa?
The generic name for all of these is tretinoin and they are in the retinoid (Vitamin A cousin) category. The difference is in the base in which they are put and the percentage of active ingredient in each. Other readers’ questions on this topic.
For sun damage (i.e. if you’re not treating precancerous conditions), a lower percentage will give you great results over time and is less irritating. Look for concentrations like 0.02, 0.025, or 0.05 percent.
The base really makes a difference. Generally, if you are dryer or over 40, use Renova. Oilier and younger the Retin-A or the generic may be fine. Refissa is formulated for extremely dry, more mature skin.
Hope the helps, Dr. I
