Pharmacist tips for Retin-A Micro (tretinoin)

pharmacist
  • Apply Retin-A Micro (tretinoin) once a day in the evening. Acne treatments take time to work, so use it regularly even if you don't see improvement right away.
  • Retin-A Micro (tretinoin) can cause dryness, redness, pain, and peeling, and your acne might temporarily get worse at first. A moisturizer can help with dryness. Contact your prescriber if irritation is severe or doesn't improve.
  • Retin-A Micro (tretinoin) can make your skin more sensitive to sunlight. Avoid tanning beds and sunlamps, and wear sunscreen and protective clothing when you're outside.
  • You can wear makeup while using Retin-A Micro (tretinoin). Make sure to remove it and gently clean your skin before applying the medication.
  • Don't use other acne products before talking to your dermatologist first. Many other products used to treat acne can interact with Retin-A Micro (tretinoin) and cause more irritation to your skin. Examples include benzoyl peroxide and salicylic acid.
  • Cold weather, wind, and certain skin products can cause more irritation while you're using Retin-A Micro (tretinoin). If your skin becomes irritated, let it recover before applying the medication again.
  • Pregnancy: Retin-A Micro (tretinoin) generally isn't recommended during pregnancy. Talk to a healthcare professional about the risks and benefits if you're pregnant or planning to become pregnant.
  • Breastfeeding: Talk to your prescriber before using Retin-A Micro (tretinoin) while breastfeeding. But it's considered low risk because little is absorbed through your skin. Use it on the smallest area needed, and don't apply it to your nipple or areola.

How to use Retin-A Micro (tretinoin)

  • Before you apply the gel, gently wash your skin with a mild cleanser and pat it dry.
  • Apply a thin layer to the affected skin and gently rub it in.
  • Wash your hands after applying the gel, unless your hands are the area being treated. This helps prevent accidentally getting the medication in your eyes or other sensitive areas.
  • Don't apply the gel to broken, sunburned, or eczema-affected skin. These areas can become more irritated.

  • Risk factors: Spending a lot of time in the sun | Having skin that's sensitive to sunlight | Using medications that make your skin more sensitive to sunlight | Using sunlamps or tanning beds | Having a sunburn

Retin-A Micro (tretinoin) can make your skin more sensitive to sunlight, raising your risk of sunburn. Limit time in the sun and avoid sunlamps and tanning beds. Use sunscreen with at least SPF 15 and wear protective clothing every day, even when it's cloudy.
