I love Olay Regenerist's line of anti-aging serums and lotions, especially their eye lifting serum.  It goes on smoothly, blending completely with one wipe.  The bottle is only 0.5 Fl Oz, but when I cannot pump any more serum out of the bottle, I open the top to get the rest out with a Q-tip.  This will leave me enough for about 2 weeks worth of serum--just a small dot is needed!

My eyes are sensitive to different lotions and cleansers but I have not had any problems with this serum.  I would recommend this product and Olay's Regenerist line of products.
