I use it for my face once a week, mixing 4-5 drops with my moisturizer and applying it all over my face carefully and diligently, at night before going to bed. In the morning I wake up with a very natural glow. It doesn't last forever, but even 2-3 drops do the job so I think the bottle will last me for a while. It doesn't dry out, doesn't cause irritation, doesn't leave awful patches. Don't overdo it with the quantity, you might end up looking orange.
