Azelaic acid before and after results commonly show smoother skin, fewer imperfections such as acne and blackheads, more even complexion, reduced redness, and lightening of pigmentation spots. Scientific studies indicate about a 50% reduction in acne lesions after 12 weeks of regular use. It also helps reduce pigment spots from melasma and sun damage, and calms inflammation and redness from conditions like rosacea. Users report improved skin texture, less visible pores, and brighter skin with consistent use. Azelaic acid works by exfoliating gently, unclogging pores, reducing bacterial growth, and inhibiting melanin production that causes dark spots. It can also help reduce post-acne scars and signs of aging due to its antioxidant properties.
