1RX Alpha Arbutin 2% Serum (30 ml) is basically a skin brightener that helps reduce dark spots, tan lines and uneven skin. It's made to control your skin's colour and boost brightness. The main thing in it is 2% Alpha Arbutin, a gentle ingredient that comes from plants. It helps keep your skin from making too much melanin. This makes your skin look clearer and more even. Since it's mild but still works, all skin types can use it, even sensitive ones. If you're dealing with acne marks, sunspots, dull skin, early discolouration, or patchy skin, this serum might help brighten things up and give you smoother, more radiant skin if you use it regularly.
