One of my favorite beauty + hydration skin tips ever came just recently to me from Trish Alkaitis of Dr. Alkaitis. Before this I would wash per usual, apply toner, and then face oil. Now much to my skin's bliss, I have been combining my toner and just a drop or two of my face oil in my palm. Mix it together and press into my face.
First, this increases not only the amount of deep hydration your skin will revel in, but also the length of time it feels this way. No more reapplying a few hours later. I stay fully hydrated and dewy all day long. And second, and most important, this will allow you to actually use less of your face oil, which is most likely the more expensive of your products.
PS :: I am doing this with my body oil as well with brilliant, long lasting results!
