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.”
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.”
