Tretinoin Gel Microsphere Administration Guidelines

Dosing and Application

• The American Academy of Dermatology recommends applying tretinoin gel microsphere once nightly to the entire affected facial area, using a thin layer sufficient to lightly cover the area 1
• Application should be at bedtime to minimize photosensitivity concerns, as suggested by the Journal of the American Academy of Dermatology 2, 1
• It is essential to apply tretinoin microsphere to all acne-prone areas to prevent new microcomedone formation, as emphasized by Praxis Medical Insights 1

Clinical Application Advantages

• Tretinoin gel microsphere formulations offer the advantage of no evening-only restriction, unlike photolabile conventional tretinoin formulations, according to the Journal of the American Academy of Dermatology 2
• They also have no benzoyl peroxide interaction concerns, unlike conventional tretinoin that can be oxidized and inactivated, as noted by the Journal of the American Academy of Dermatology 2
