What the gurus are saying

This serum stands out for pairing retinol with a generous dose of PDRN from lactobacillus, which gurus praise as one of the best sources of the ingredient available. Green tea, niacinamide, and hydrating ingredients round out the formula to soothe potential redness, and reviewers found the retinol concentration gentle enough not to trigger irritation or sensitivity even when switching from other retinol products. The texture is smooth and the overall formula is well-balanced for anyone seeking multi-benefit anti-aging in one step.

"After using it for about a month, I really believe this is one of the best PDRN products out there, because you're getting both PDRN and retinol delivered into the skin. The PDRN it uses is vegan, sourced from lactobacillus, which next to salmon and trout is the next best type of PDRN from a research standpoint, and it's the first ingredient so this one is loaded. It also has green tea, which is great for soothing redness and irritation, niacinamide, urea, and tons of hydrating ingredients."

"This is where I really like the Innisfree Retinol Green Tea PDRN Firming Serum. It has a nice texture to it, as most Korean serums do, and it has a little retinol in it plus PDRN, so you're getting some peptide type action, plus green tea antioxidants to help with anti-aging."
