• Tretinoin should be used once a day, before bedtime, or as advised by your doctor. If your skin is sensitive, your doctor may recommend that you begin your treatment by applying Tretinoin every other night. Wash your skin with a gentle soap and pat it dry gently. WAIT 20–30 MINUTES BEFORE APPLYING MEDICATION; it is essential that the skin is completely dry in order to avoid irritation.
• Squeeze out a half-inch or less of medication onto the tip of your finger. While it should be sufficient for your entire face, you may find that you require somewhat more or less after some practice with the drug. Almost immediately, the medication should become undetectable.
• If it's still visible, you're overdoing it. Apply Tretinoin (tretinoin cream) Cream to the affected region, dabbing it on your forehead, chin, and both cheeks first, then spreading it over the entire affected area. Gently massage onto the skin.
