It gives radiance, glow, evens out my skin texture, and most importantly is malassezia safe. Post-acne dark spots also healed a lot quicker. Been using it since 2019 in my mid-20s and planning on using it forever. It's truly a HG for me. Please don't make any unnecessary reformulations on this one.
