@cherriann, I just opened your post and saw Systane. That is what I use and I will share my reasons. I have itchy skin and have allergies to sulfa. I only use products that have passed the dermatology guidelines for eye products without sulfa. Systane is one of them. Just an FYI really. Aging eyes are a reality. It is 91% humidity today where I live now and 12% humidity where II used to live. My eyes say thank you to me every day. Thanks so much for sharring.
