Anua vs SKIN1004 azelaic acid: which one actually works for your skin? Both are 10% azelaic acid but built totally differently. SKIN1004 has 3 forms of azelaic acid + no niacinamide + lightweight. Anua adds niacinamide + ceramides + is more hydrating. Dry skin → Anua Sensitive/oily/no niacinamide → SKIN1004 For transparency, the SKIN1004 ampoule was already in my routine before this partnership. I've also personally used the Anua one. @SKIN1004 US #skin1004 #azelaicacid #acne #centella #koreanskincare
