That stuff you before serum and moisturizer but after cleanser....

Toner gets your skin ready for moisture and treatments. Like a sponge, your skin accepts moisture better when it's full of water. Toner also gets rid of any remnants of cleanser and any nasty things in the water you used to rinse with...like chlorine and minerals. ALSO, if you have dry skin, like me, it is one more opportunity to add moisture. I love toners that have a gel texture. These are my faves:
Shiseido Eudermine Revitalizing Essence 



Laura Mercier Perfecting Water Rich


Erno Laszlo HydrapHel Skin Supplement 


Clarins Extra Comfort Toning Lotion
