What Is Tretinoin Gel 0.04%-20g?
Tretinoin gel is a topical retinoid that affects how skin cells grow and shed. It helps prevent dead skin cells from blocking pores, which can contribute to acne.
Tretinoin is not an antibiotic or a corticosteroid. It works directly on processes involved in acne formation.
This medicine is intended for use on the skin. It should not be swallowed or applied inside the eyes, mouth, or vagina.
What Is Tretinoin Gel Used For?
Tretinoin gel 0.04% is used for the treatment of acne vulgaris in adults and adolescents aged 12 years and older.
Acne occurs when pores become blocked by oil and dead skin cells. This can lead to blackheads, whiteheads, and inflammatory pimples.
Tretinoin may help:
Reduce blocked pores.
Treat blackheads and whiteheads.
Reduce the formation of new acne lesions.
Improve acne with continued treatment.
Tretinoin does not provide immediate results or permanently cure acne.
Other tretinoin formulations may be prescribed for additional skin concerns. However, acne is the approved indication for the 0.04% gel formulation discussed here.
How Does Tretinoin Gel Work?
Tretinoin helps normalize the growth and shedding of skin cells inside hair follicles.
This process reduces the buildup of dead skin cells that can block pores and contribute to acne.
Treatment works gradually. Some patients notice temporary skin irritation or increased acne during the early weeks.
Using more gel than prescribed will not make the treatment work faster.
How to Use Tretinoin Gel 0.04%
Use tretinoin gel exactly as directed by your healthcare professional.
US labeling for tretinoin gel microsphere 0.04% recommends applying a thin layer to acne-affected skin once daily in the evening.
Application Instructions
Wash your hands and gently cleanse the affected skin.
Rinse thoroughly and pat the skin dry.
Apply a thin layer over the acne-affected area.

Use only enough gel to cover the affected area.
Do not apply extra medication or use it more frequently than prescribed. Avoid applying tretinoin to sunburned, damaged, or eczema-affected skin.
A gentle moisturizer may help reduce dryness.
How Long Does Tretinoin Take to Work?
Some patients may notice improvement after approximately two weeks. However, more than seven weeks of treatment may be needed for sustained improvement.
Acne can temporarily appear worse during the first few weeks.
Continue using the medicine according to your prescription. Contact your healthcare professional if irritation becomes severe or your condition continues to worsen.

Pregnancy and Breastfeeding
Avoid using topical tretinoin during pregnancy or while planning pregnancy unless your healthcare professional has specifically assessed the situation.

If you become pregnant while using tretinoin, stop treatment and contact your healthcare professional.
