Keep [azelaic acid](https://lovi.care/skincare/it/ingredients/azelaic-acid) and [lactic acid](https://lovi.care/skincare/it/ingredients/lactic-acid) apart in your routine, as combining them may cause over-exfoliation and inflammation. Instead, use them on alternate days. ### Which goes first, azelaic acid or lactic acid? Keep azelaic acid and lactic acid apart by alternating their use in your routine to avoid over-exfoliation and inflammation. Products such as MZ Skin Radiance & Renewal Instant Clarity Refining Mask, Farmacy Brighten Up 3% TXA, and Dr. Sebagh Deep Exfoliating Mask contain both ingredients, so they should be used separately. ### Are azelaic acid and lactic acid good for sensitive skin? Azelaic acid and lactic acid should be kept apart in your routine, as combining them may lead to over-exfoliation and inflammation, especially on sensitive skin. You can alternate their use on different days. ## Research on azelaic acid and lactic acid - [Lactate triggers KAT8-mediated LTBP1 lactylation at lysine 752 to promote skin rejuvenation by inducing collagen synthesis in fibroblasts](https://pubmed.ncbi.nlm.nih.gov/39102921/) Lactic acid · International Journal of Biological Macromolecules, 2024 -
