Reviewers in their 70s say this anti-aging serum makes a big difference: 'My deep lines are gone!'

When it comes to anti-aging skin-care products, it can be tricky trying to find the right ones. With so many options, it's hard to know which one will work best for you. If you're looking for a serum that will actually make a "noticeable difference," we've got good news: Over a thousand Amazon shoppers have given the RoC Retinol Correxion Serum their five-star seal of approval — and it’s on sale now, courtesy of the site's Big Spring Sale.

Why is this a good deal?

At just $19 (down from $33), this serum is a fraction of the price of many high-end skin-care products with retinol, which can run you upward of $50 or even $100. RoC has been a respected brand for decades, and at over 40% off right now, it's a great time to take advantage of this markdown.

Why do I need this?

The fast-acting formula delivers numerous skin-care benefits, including diminishing the appearance of fine lines and wrinkles, lightening dark spots and hyperpigmentation, plumping and hydrating skin and making large pores appear smaller. It uses a time-released, stabilized form of pure RoC Retinol that works for up to 12 hours.

Along with retinol, the serum is packed with other potent ingredients like squalane and ashwagandha that are gentle on the skin but still super effective. We love when anti-aging products actually live up to their claims, so we were happy to see that in a four-week consumer study, 94% of users said they saw a visible reduction in pores, 87% saw an improvement in fine lines and wrinkles and a whopping 100% said they had visibly plumper, more hydrated skin.

What reviewers say

Shoppers of all ages are fans of the top-rated serum, too. “I love this product. Use it [on] my face and all over my neck. I'm 81 years old and my lines and have improved a lot,” raved one.

"I use this cream every night before going to bed — I just love it so much!" wrote another. "The cream works well by diminishing fine lines, like, instantly. I use this every night and have received compliments from my co-workers that I look younger than 61 years of age."

A third said: “I'd love to submit a before and after of my amazing results, but unfortunately, I did not take one, as I figured it would be another disappointment. However, I'm in week 8 of this product (second purchase), and I cannot believe the results. My deep lines are gone! My pores are less noticeable, too!"

"I'm a fan of RoC products, and when I saw this, I had to try it," shared a final fan. "First of all, the texture is wonderful. It is very sheer. I hadn't noticed a scent really, which I love. ... The product absorbs well. It does dry a little tacky, but moisturizers and makeup go on just fine. Instantly I noticed a reduction in pores, my skin does feel hydrated and it overall looks and feels firmer. ... The ONLY con: I like the bottle that the product comes in, but the dropper is NOT great at getting the product out. When you get toward the bottom of the bottle, do yourself a favor and have a little brush or something handy to get the rest out." (Psst: This mini beauty spatula was designed to do just that!)

'It contains seven moisturizers, including shea and cocoa butters, to help keep skin hydrated,' our reviewer said. 'I'm pretty sure it's because of this that I woke up after the first application with zero redness or itching. But even better? My skin felt noticeably more moisturized and smoother just eight hours after I'd slathered it on, and stayed that way the rest of the day.'
