Key takeaways
Arazlo (tazarotene) and Retin-A (tretinoin) are both topical retinoid medications used to treat acne. They work by promoting the growth of new skin cells and reducing oil and inflammation. Arazlo is approved for use in people as young as 9 years old, while Retin-A is approved for those ages 12 and older. Arazlo is available as a lotion with a concentration of 0.045%, whereas Retin-A comes in cream or gel form. Both medications are applied once daily, but Arazlo is typically used during the day, and Retin-A is applied at bedtime. Common side effects for both include skin irritation and increased sensitivity to sunlight, but Retin-A may also cause your skin color to temporarily change. Retin-A is available in a lower-cost generic form, while Arazlo is only available as a brand-name medication.
