Retin-A Micro is used to treat acne by decreasing the number and severity of acne pimples and promoting quick healing of pimples that develop.

Tretinoin, the active ingredient in Retin-A Micro, belongs to a class of medications called retinoids. It works by affecting the growth of skin cells, which can help in reducing acne and promoting skin health.


  • Wash your hands thoroughly before applying the medication.
  • Cleanse the affected area with a gentle cleanser and pat it completely dry.
  • Apply a pea-sized amount of the gel in a thin layer to the affected area, once daily at bedtime (unless your healthcare provider instructs differently).
  • Use a gauze pad or cotton swab for application (if applicable).
  • Follow the specific instructions on the label or consult your healthcare provider if unsure about waiting time after cleansing.
  • Use the medication only on your skin and avoid these areas: inner lips, nose, mouth, cuts, scrapes, sunburns, and eczema.
  • Be very cautious around the eyes. Rinse thoroughly with water if the medication gets in your eyes.
  • Use the medication consistently to see results.


  • Don't apply the medication to your eyes, nose, mouth, or inner lip area.
  • Don't use Retin-A Micro on broken, sunburned, or irritated skin.
  • Don't increase the dosage or use it more often than prescribed. This won't improve results faster and might cause irritation.
  • Don't stop using the medication abruptly if you've been on it for a long time. Talk to your healthcare provider first.
  • Don't expect immediate results. It can take 8-12 weeks to see improvement with Retin-A Micro.
