The peptide-infused serum promises to reduce wrinkles and visibly smooth the skin for a rejuvenated and more youthful appearance. The serum uses peptides to hold up to its promises. So what exactly are peptides and why do they matter? Well, according to the Medical Dermatology Associates of Chicago, peptides are naturally made in our bodies and contribute to keeping skin looking its best. The tiny molecules contribute to keeping collagen production strong and consistent. As we age, the collagen in our skin breaks down over time, causing fine lines, wrinkles, and sagging skin to occur. That’s where peptides come in. “These peptides send a ‘signal’ to alert your skin that it has lost collagen and needs to generate more,” they explain. And, when peptides are added to skincare, they also signal to your skin that it’s time to produce more collagen. Olay’s Regenerist Wrinkle Serum Max also has one form of vitamin B3 in its mix—known as niacinamide. The niacinamide hydrates and brightens the skin, combats hyperpigmentation, and helps strengthen the skin’s elasticity. The combination of the peptides and the niacinamide make the serum a potent anti-aging skincare product you’ll want to use, if you’re not already. To buy: $35 (was $44); olay.com. Shoppers love the formula and can’t stop sharing their impressive results.“Olay has done it again,” one shopper said. “Within a month of use, I can see a huge difference in the tiny wrinkles and fine lines that I have around the outer corners of the eyes [as] they have significantly diminished. My skin also looks and feels amazing; it’s smoother and has a super glow to it.” “Act my age, maybe. Look it, never,” another reviewer wrote. “This serum makes my skin feel so smooth and has improved the appearance of any fine lines and wrinkles. I was recently at the doctor with no makeup on, and the nurse looked at my chart, looked at me, and said, ‘Wow, you really do not look your age.’” Safe to say you can’t get results much better than that. If you are looking to erase fine lines and wrinkles (and really, who isn’t?), then give the wrinkle serum a shot. Head to Olay now and add it to your skincare arsenal while it’s on sale for $35.
