I've used prescription Azeliac Acid for decades ( Skinoren ) to help control my adult acne and rosacea . I wsnt aware at the time that one of this amazing acids " Side effects " Was anti aging properties as well ! This product is superior as the base of the actives the cream itself .. feels lux and is smooth in application . Im 55 years old and have sent you a photo . There are no filters on this pic whatsoever ! My skin is smooth and my redness and discoloration , diminished even more dramatically than with my normal prescription ! This is a MUST have product
