I am obsessed with skincare and have bathroom drawers, shelves, and cabinets overflowing with products as proof. If there is a new moisturizer, serum, or face wash available from a buzzy brand, I’ve probably tried it, and the same goes for any celebrity-worn products.
Recently, I got the chance to test OneSkin’s OS-01 Face Moisturizer, which Parker Posey’s makeup artist used to achieve the actress’s glowy makeup look at the Actor Awards. After just two weeks of incorporating it into my daily routine, I noticed my skin looked smoother, more even, and radiant. Even better, you can score 20 percent off all of OneSkin’s products with our exclusive code OS20.

Since I’ve tried at least 30 other moisturizers that promise to erase fine lines and leave my skin hydrated for hours, my standards are high. I used this after my usual morning beauty routine for the first time and was impressed that just one pump covered my face and jawline. Thanks to the hyaluronic acid and glycerin, which both help lock in moisture, my face looked dewy all day.
While I don’t wear a lot of makeup day-to-day, I usually put on color corrector in the morning to help reduce redness on my cheeks and nose. However, after two weeks of using the cream twice daily, my complexion looked remarkably more even. I even found myself skipping face makeup altogether and just adding a bit of blush and mascara for nights out — a huge win for me, as I don’t like to layer thick makeup on my acne-prone skin.
The standout ingredient is the brand’s signature OS-01 peptide, which targets damaged cells that can cause inflammation and diminish collagen and elastin. The formula is designed to eliminate these cells and improve the skin barrier, leading to a healthier, smoother appearance in 12 weeks, according to the brand’s clinical studies. In a short time frame, I noticed a dramatic reduction in the fine lines around my eyes and mouth, as well as less pronounced forehead wrinkles. Since I don’t have the budget for Botox, this alone made me a fan for life.
Shoppers also shared that their skin improved with consistent use, with one person saying theirs “looks and feels like silk” and another adding that it’s “brighter and more even.” A 79-year-old customer said they’ve used the moisturizer for three years and noted their “skin is soft and supple with relatively few wrinkles.” That same reviewer’s doctor told them they looked 20 years younger — results they credited to OneSkin.
