I had the worst nightmare using the APLB Tranexamic Acid Niacinamide Lotion. I used this product consistently for about three weeks, hoping it would help with brightening and hyperpigmentation, but instead it completely damaged my skin barrier. What started as mild irritation quickly turned into severe itching, redness, inflamed bumps, and intense skin sensitivity. Eventually, my skin developed dermatitis-like symptoms with painful inflammation, red rashes, and even slight bleeding in certain areas from constant irritation and scratching. Instead of improving, this lotion made my skin look worse — angry, inflamed, textured, and extremely reactive. The itching was unbearable, and the red bumps took a long time to calm down. If you have sensitive skin or are prone to eczema, contact dermatitis, or allergic reactions, please patch test very carefully before using this product. My experience was honestly terrible, and recovering my skin afterward took much longer than the three weeks I spent using it. (Still recovering after 2 months)
