"[Retinol] boosts collagen production and aids in appropriate cell turnover. This results in more even, smoother skin, and helps reduce the appearance of sunspots, fine lines, and wrinkles," dermatologist Shereene Idriss, M.D. previously told Shape.

If you struggle with acne or have begun to see some wrinkles, then the Bioniva Retinol Serum will have you praising the skin gods.

Aside from retinol, Bioniva's anti-aging serum also includes vitamin C which is the ingredient which brightens the skin and gives skin a glow.

The serum also contains hyaluronic acid and Vitamin E which team up and counteract retinol's potential irritating and reddening side effects. And best of all, the Bioniva Retinol Serum is completely vegan. Meaning, this retinol face serum does not include any animal-derived ingredients — plus, it's cruelty-free, so it's not tested on any animals, either. What's more, it's also free of parabens, which are potential endocrine disruptors and can be irritating for some users.

"I recently bought some great beauty products on Amazon. Because I noticed the change in less than a week. I've been using it for more than two weeks."

"The line between my mouth and my cheek almost disappeared. The other one is getting smaller and smaller. The skin on my face looks much better. My twenty-four-year-old son even commented on it. Best of all, (I'm forty-four and have four boys between the ages of 24 and 4), and someone commented that I didn't look old enough to have a 24-year-old. I haven't seen anything like it in all these years. I use it with retinol. I believe it will make the ointment more effective. It doesn't hurt;In fact, it feels good on the skin"

"I began to see results in just under 2 weeks!" writes another shopper, who purchased the serum to help out with dark under-eye circles that never went away with other products.

"After about a week and a half, I could swear I saw some brightening of the skin but I couldn't be sure. After 2 weeks, I was SURE! I'm so happy!"
