If you're into clean beauty and avoiding hormone disruptors because of the long-term consequences, you're probably familiar with Credo Beauty and The Detox Market. Less well-known but equally worthwhile is Aillea, a hub of cruelty- and petrochemical-free beauty products expertly curated by Kathryn Murray Dickinson, a former beauty industry executive. And according to shoppers, one of the store's serums blows other anti-aging hydrators out of the water. 

Fans of Osea's Hyaluronic Sea Serum wrote that they notice an immediate difference in the texture of their skin upon applying the serum, an effect that leaves them "absolutely obsessed" and drawing comparisons to $300 products. Per a 65-year-old, the serum made their face feel more firm but not oddly tight, and another person wrote that after a couple weeks of use, their skin "looks a lot smoother, less irritated, and fresher/younger." 

Osea has been around since the '90s, and in its 26-year stretch the brand has racked up celebrity fans like Naomi Campbell, Mandy Moore, Sophia Bush, Alexandra Daddario, Victoria Beckham, and Jenna Dewan. Shoppers on the brand's website are effusive about how well the Sea Serum works: One person said their coworker asked if they had gotten Botox thanks to it, and another fan commented that the fine wrinkles on their forehead are "gone" because of the formula.

Said formula includes both high and low molecular weight hyaluronic acid, combined with seaweed and snow mushroom extract. As certified dermatologist Dr. Lian Mack, MD, previously told InStyle, "Hyaluronic acid found in moisturizers and serums can help to reduce wrinkles and fine lines by creating a barrier that retains water in the skin." And Osea's inclusion of snow mushroom was prescient; fungi is everywhere in skincare these days thanks to the ingredient's free radical protection

The blend means even people with "very reactive," sensitive skin see a "huge reduction" in wrinkles, and "deep," long-lasting lines transform into a shadow of themselves. Users also mention seeing their sun damage, hyperpigmentation, and redness alleviate within two weeks, while the firming effect emerges in one more. "Using these products now for three weeks, I feel like I had a little Botox," wrote a last customer in their 50s. "All the lines and light wrinkles have decreased." 

If you'd like to try the "miracle in a bottle" flooring skincare lovers, pick up the Osea Hyaluronic Sea Serum from Aillea, Credo Beauty, Amazon, or the brand's website.
