Recommended by my dermat a couple of months ago. really great when used with the night cream. Reduced pigmentation very effectively and is made with natural ingredients so does not flare up my skin like kojic does in summer. Apply liberally like a moisturizer, that is enough. Don't apply too much like a sunscreen otherwise it will leave a little bit of white cast. Also, they could improve the formula a little because in dry summers or winters tends to pill/ball if you rub too much. I just add a few drops of oil, but it keeps my skin more matt for the oily months like right now. Much better detaining effect than sunscreen alone even with spf 50.
