Overview
Overview of tretinoin as a topical retinoid medication available in Canada.
Tretinoin is a synthetic derivative of vitamin A classified as a retinoid. It is available in Canadian pharmacies under several brand names including Retin-A®, Airol®, and Stieva-A®. These brands offer tretinoin primarily as a topical formulation designed to affect skin cell behavior. While the medication is widely used, treatment decisions must always be discussed with a healthcare professional to ensure suitability and safety.
How Tretinoin Works
How tretinoin works biologically at the cellular level.
Tretinoin works by binding to retinoic acid receptors in skin cells, regulating gene expression that influences cell growth and differentiation. This action helps to normalize skin cell turnover and promotes the shedding of old cells while supporting the production of new cells.
Dosage Instructions of Tretinoin
Forms of tretinoin available in Canada.
In Canada, tretinoin is commonly available as topical creams, gels, and microsphere gels with concentrations typically ranging from 0.01% to 0.1%. These formats allow for varied application depending on medical guidance.
General guidelines for safe tretinoin use.
Tretinoin should be applied in a thin layer to clean, dry skin as directed by a healthcare provider. Typically, it is used once daily, preferably at night. Avoid contact with eyes, lips, and mucous membranes. Follow all instructions carefully and consult a doctor before changing dosage or usage frequency.
Storage Instructions
Proper storage to maintain tretinoin stability. Store tretinoin at room temperature between 15°C and 25°C (59°F to 77°F). Keep the container tightly closed, protected from light and moisture. Do not freeze and keep out of reach of children.
Side Effects of Tretinoin

Important Safety Information About Tretinoin
Key Health Canada warnings and precautions.
Tretinoin is for external use only and should not be used on damaged or broken skin. Avoid excessive sun exposure and use sunscreen due to increased photosensitivity. Pregnant or breastfeeding individuals should consult a doctor before use. Follow all safety warnings on product packaging and official monographs.
Drug Interactions

Avoid using other topical products that may cause irritation such as abrasive soaps, astringents, or products containing alcohol or other retinoids unless approved by a healthcare provider. Combining tretinoin with certain medications may increase skin sensitivity.
