Tretinoin is vitamin A. It is the purest form so it can be harsh when not used properly. You can get it in different percentages starting at 0.1%. It is usually prescribed by a derm.Does tretinoin replace retinol? Can you use them both? I've never heard of it.
Retinol is a conversion of tretinoin. It is less aggressive and easier to use because it has been mixed with emollients and moisturizing factors. You can easily find products in the drug store that contains it.
There are other conversions but Trent is superior to them all because you are getting the purest form. If you have really sensitive skin then start with the lowest percentage and layer it over your moisturizer.
You don't need both. Just one or the other.
