I apply this right after I shower or cleanse my face and let it work it’s magic for at least an hour or two if I can (not sure if this would work for sensitive skin types, but this method works for me).
I have noticed a significant improvement with brightening (minimizing scars) and removing dullness. It gives my skin the "freshly scrubbed just-got-out-of-the-shower" luminosity that people with great skin seem to have.
I'm so happy with the RESULTS I've seen with this.
The only downside is that it's so darn expensive. :(
