Tretinoin cream is available in several strengths. In the US, the strongest tretinoin cream on the market contains .Tretinoin 0,1 creams, or one unit of tretinoin per 100 units. The weakest cream contains .005% tretinoin, or approximately 5% as much tretinoin as the strongest .1% cream.
You can also purchase .025% and .05% strength tretinoin creams, although not all brands offer tretinoin cream in these concentrations.
All tretinoin products are available on prescription only in the United States, meaning you’ll need to talk to your doctor before being able to buy tretinoin cream in any concentration.
