Tretinoin gel is a topical prescription medication used to treat acne vulgaris in adults and patients 12 years and older. It belongs to a group of medicines called retinoids, which act directly in the skin to address acne at the pore level. Based on the prescribing information provided, the supported strengths for this formulation are 0.04%, 0.08%, and 0.1%.

• A prescription topical treatment for acne vulgaris
• Part of the retinoid class of medications
• Applied directly to acne-prone skin
• Intended for consistent, ongoing use
• Not for oral, eye, or internal use

Tretinoin gel is typically applied once daily in the evening. It should be used as a thin layer over the entire affected area after gently cleansing and drying the skin. The exact way it works is not fully known, but it is associated with changes in skin cell turnover and the formation of clogged pores.

• Apply once daily, usually in the evening
• Use a mild cleanser before application
• Spread a thin layer over the affected area
• Avoid contact with eyes, mouth, and sensitive areas
• For topical use only

Tretinoin gel commonly causes local skin reactions, especially when starting treatment. These effects are usually limited to the treated area but can become more noticeable depending on skin sensitivity or how the product is used.

• Skin irritation such as redness, dryness, peeling, or burning
• Itching or discomfort at the application site
• Sensitivity to sunlight during treatment
• Stop use and contact your provider if severe irritation develops
• Seek medical advice if symptoms like swelling or blistering occur
