It's band of dedicated fans in the reviews section claim you will "not be disappointed" by the anti-aging serum's potential results, with one sharing that it's ability to "plump smile lines and erase lines around the eyes" are truly "nothing short of a miracle." After a month of consistent applications, another person wrote that their skin looked "nearly perfect" and saw a noticeable reduction in dark spots.

"I don't normally write reviews but I had to take time to write about this product," shared one reviewer. "I've had skin discoloration for most of my life, and use hydroquinone creams and have a prescription from my dermatologist to help even my skin tone... Within the first night of using [this serum] I saw a difference. At first I thought maybe it's just a coincidence, but a week later the dark spots were significantly lighter and my skin tone looked more even. It's been two weeks now and I'm ready to throw away all those creams and RX's."

"This is probably the only facial serum I've [used] that has really helped me," said another. "I've only used this for three days, and it's really evened out my skin texture, cleared up a minor breakout I had going on, and I've noticed a reduction in my fine lines already! I love that this serum is water-based so it goes on smoothly and doesn't make my skin feel oily."
