This concentrated whitening lotion prevents dark spots from forming. Tranexamic acid, a medicated whitening lotion, prevents dark spots and leaves skin translucent. It penetrates deep into the skin, resulting in a truly translucent complexion. Feature 1: Stops excessive melanin production, preventing dark spots. Feature 2: Prevents dry skin roughness, which can lead to dark spots. Feature 3: Because it's concentrated, the active whitening ingredients are delivered directly. Tranexamic Acid Whitening Mechanism: Dark spots occur when inflammation caused by UV rays or external stimuli leads to the production of melanin. Stubborn dark spots are caused by the accumulation of UV and other stimuli, resulting in the continued excessive production of melanin, the underlying cause of dark spots. Therefore, even with UV protection and melanin excretion, dark spots will continue to form unless excessive melanin production is stopped. Tranexamic acid inhibits the production of plasmin, a substance that activates melanocytes, which produce melanin, and suppresses inflammation caused by stimuli, thereby suppressing excessive melanin production. By doubling down on the mechanism behind dark spots, it thoroughly prevents their formation.
