Review title is Vitamin C serum with a slightly thick texture, takes a little time to be absorbed [SEP] I'm always interested in trying new skincare innovations, products and brands.  I'm new to this American brand MD Complete but found the Vitamin C serum nicely packaged and high quality.<br /><br />I use different serums in the morning and at night. This Vitamin C is a little thicker than what I usually use and is feels a bit oily -- but going on it is absorbed quickly and doesn't leave the skin feeling greasy.  I would use it at night though.  It felt deeply hydrating and the Vitamin C helps brighten and even out skin tone.<br /><br />I have sensitive skin but did not experience any irritation, sensitivity or redness using this product.
