How should I use tretinoin topical?
Do not take by mouth. Tretinoin topical is for use only on the skin. Do not use this medicine on open wounds or on sunburned, windburned, dry, chapped, or irritated skin.
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Using more medicine or applying it more often than prescribed will not make it work any faster, and may increase side effects.
Wash your hands before and after applying tretinoin topical. Before applying, clean and dry the skin area to be treated.
Applying tretinoin topical to wet skin may cause skin irritation. If you use Renova, wait at least 20 minutes after washing your face before applying a thin layer of the medication.
Do not wash the treated area for at least 1 hour after applying tretinoin topical. Avoid the use of other skin products on the treated area for at least 1 hour following application of tretinoin topical.
Applying an excessive amount of tretinoin gel may result in "pilling" of the medication. If this occurs, use a thinner layer of gel with the next application.
Tretinoin topical should be used as part of a complete skin care program that includes avoiding sunlight and using an effective sunscreen and protective clothing.
Use this medication for the full prescribed length of time, even if you think it is not working.
It may take up to several weeks before you notice improvement in your skin. Keep using the medication as directed and tell your doctor if your symptoms do not improve. If you are using tretinoin topical to treat acne, your condition may get slightly worse for a short time when you first start using the medication.
Call your doctor if skin irritation becomes severe or if your acne does not improve within 8 to 12 weeks.
Store at room temperature away from moisture and heat. Keep the bottle tightly closed when not in use.
Tretinoin topical gel is flammable. Do not use near high heat or open flame. Do not smoke until the gel has completely dried on your skin.
