@heylina2484: So many of you asked which one is better SKIN1004 or Anua Azelaic Acid Serum, so I made this comparison! Hope it helps 🤍 @SKIN1004 US • 11.5% azelaic acid • no niacinamide • watery & lightweight • best for sensitive skin @anua_global • 10% azelaic acid • contains niacinamide • thicker & more hydrating • best for dry skin #azelaicacid #skin1004 #anua #acne #skincare
