After cleansing in the A.M., apply 5-7 drops on the face, neck and upper chest. Allow to air dry, then apply sunscreen and/or make-up. Slight tingling may occur initially, but will diminish with continued use.
I would never miss a morning without my Professional-C. Nothing gives my skin a glow and firmness like this little miracle. I started out at a 10% but can now tolerate 20% and I love it!
I use this product twice a day. It encourages new skin cell growth, and helps clear away the dead cells, leaving my skin always looking fresh and young. My skin is somewhat sensitive and somehow even the 20% doesn't irritate it.
