Good to know
When will I see a difference in dark spots?
Dark spots fade slowly. In our 4-week human test, the look of dark spots dropped by 25.54%. Give it at least 4 weeks of daily use, and wear sunscreen every day, since sun brings spots back.
Is it OK to use every day?
Yes, morning and night. It scored an irritation index of 0.00 in a skin patch test, and it already contains a stable form of vitamin C, so you don't need a separate vitamin C serum.
It feels a little sticky. Am I using too much?
Probably. 2–3 drops cover your whole face and absorb in seconds. Pat it in, then follow with moisturizer or sunscreen.
I have sensitive, breakout-prone skin. Should I try it?
Most reviewers with sensitive skin had no irritation, and it scored 0.00 in a patch test. Everyone's skin is different, so try it on a small area for 2–3 days first and add one new product at a time.
