Dealing with fine lines and wrinkles can be a challenging aspect of aging. According to a recent survey of over 1,300 NewBeauty readers,* one serum has stood out for its ability to soften these visible signs of aging and provide a smooth, glass-like finish: SkinCeuticals P-Tiox ($148).
While many serums claim to firm and enhance skin appearance, P-Tiox has received praise from users of all ages for actually delivering on its promises. A 60-year-old reader shared, “I’ve been using this at night for about two months now, and I can visibly see a difference in the deeper lines around my mouth and eyes.” Another reader, aged 29, noticed a “major improvement in smile lines, forehead lines, and nasolabial folds” after just a few weeks. Others reported similar results within the first week, experiencing smoother texture, plumper skin, and a more even tone.
What’s Inside: The Formula Behind the Results
So what sets P-Tiox apart? This peptide-powered serum is inspired by the wrinkle-reducing effects of neurotoxin injections but is designed to be completely noninvasive.
At the heart of the formula is an advanced peptide complex clinically proven to reduce the appearance of nine different types of expression lines. It is complemented by a trio of high-performance ingredients targeting various signs of aging: 5 percent PHA for smoothing and refining texture, 5 percent niacinamide for evening tone and strengthening the skin barrier, and 1 percent laminaria extract, a marine-derived ingredient known for its soothing and hydrating properties.
The formula has also been tested by physicians to complement neurotoxin injections, but it is equally effective on its own, providing a needle-free solution for visible wrinkle improvement.

Visible Results Fast
Users have reported significant improvements in skin texture, tone, and fine lines in a shorter time than expected.
A 46-year-old reviewer mentioned, “This is the only serum that has truly helped my fine lines and wrinkles. Over a few weeks, I have found my wrinkles and fine lines to be improved as well as redness and skin tone issues. It has completely surpassed other serum efficacy in my opinion.”
Another user noted that the serum made “skin look glassy and evened out skin texture. Saw results in a few weeks. No side effects for me,” they added.
Several users also found that it helped extend the effects of their neurotoxin injections, making it a valuable addition to both professional and at-home skincare routines.
The Bonus Benefits
What makes P-Tiox even more appealing is its multitasking properties. Many users observed more than just wrinkle reduction—such as refined texture, improved hydration, and a radiant, youthful finish.
“Softens contraction lines and gives glass skin radiance,” noted a 54-year-old reviewer. “My pores are smaller, and my skin is more hydrated and plump,” said a 38-year-old after just a week of use. “I cannot live without this product now.”
Importantly, users also reported no irritation or negative side effects—just smooth, even, radiant skin.
