I have been using this trio for over a year. Not because they were trending. Because they work on my skin. Naturium Azelaic Acid 10%, Vitamin C Complex Serum, and Tranexamic Acid 5% Three drugstore-accessible actives that target hyperpigmentation from three different angles. ✨Azelaic acid on the melanin overproduction. ✨Vitamin C on the oxidative damage and dullness. ✨Tranexamic acid on the hormonal pigmentation that SPF alone cannot touch. I have melasma. Combo skin. Mature texture. I use prescription tretinoin. This trio survived my skin cycling routine, my tretinoin nights, and a year of Bend Oregon altitude sun. They are still here.
