Our 15% Azelaic Acid Complex Serum helps visibly reduce blemishes, redness, dark spots, and uneven skin tone. Designed to promote a clearer, smoother, more radiant-looking complexion.

Apply 2–3 drops to clean, dry skin after cleansing. Gently massage into your face until absorbed, then follow with moisturizer. Start once daily or every other day, depending on skin tolerance. Always use SPF 30+ during the day.

With consistent use, some users may notice smoother-looking skin within 2–4 weeks. Improvements in the appearance of blemishes, redness, and dark spots may take 6–12 weeks. Results vary.

Orders typically arrive within 7–10 business days. If you have questions about your order, our customer support team is here to help. Returns are subject to our store's return policy. 

Backed Up Dermatologist

We formulated this serum stick because patients kept telling me the same thing: their retinol was too harsh for the neck, so they skipped it entirely. Retinaldehyde delivers the results of a true retinoid with a gentler experience. And unlike a serum that drips and is easy to skip below the chin, the stick glides on right where you need it.
