Can You Use Azelaic Acid and Retinol Together?

Linda Girgis | MD

Yes, azelaic acid and retinol can be used together, but timing and application method are crucial for optimal results. Dermatologists recommend starting with alternating nights to assess skin tolerance, as combining these actives can initially cause irritation. Azelaic acid works as a gentle exfoliant and anti-inflammatory, while retinol accelerates cell turnover and collagen production. Studies show that 20% azelaic acid combined with 0.25% retinol improves acne and hyperpigmentation more effectively than either ingredient alone. Apply azelaic acid first, wait 10-15 minutes, then follow with retinol to minimize interaction. Always use sunscreen during the day, as both ingredients can increase photosensitivity by up to 40%.
