"I've used other "brightening" products over the years and had come to the conclusion that they just don't work...or work well enough for me to notice any change, anyway. But when I saw that Enessa has such a product I had to give it a try. Covid has certainly not done my face any favors and with the "luxury" of wearing a mask, there seemed to be no impetus to bother about anything but the basics. I am so happy I gave the Plantcell Brightening Serum a try, though. After several weeks, dark spots have started to fade and my skin has taken on a new clarity. I'm hooked."
