Use your azelaic acid serum correctly
To start, choose a concentration of 10 percent and apply your azelaic acid serum every other evening, to perfectly dry skin, followed by a simple moisturizer. After two weeks without any particular discomfort, it becomes possible to move on to daily application, or even morning and evening on skin already accustomed to the active ingredients.
In routine, it combines well with niacinamide, hyaluronic acid or simple moisturizing creams; instead alternate with retinol or stronger AHA BHAs rather than layering everything on top of each other. Used daily, azelaic acid improves acne and redness in four to six weeks, while hyperpigmentation and post-acne marks often take two to three months; consult a dermatologist if rosacea is severe or accompanied by pain.
