Evidence: In an 8-week randomized, vehicle-controlled split-face study of 23 people with blemish-prone skin, an anhydrous 0.1% retinal / 10% azelaic acid concentrate improved the pore parameter by 22.3% versus vehicle (p=0.015) and skin texture by 5.6% versus vehicle (p=0.0016), and reduced surface irregularities by 12.7% versus vehicle (p=0.0053).
