My Highly Sensitive Skin Loves This Fine Line-Smoothing Serum

 It’s packed with hyaluronic acid and seaweed.

Osea Hyaluronic Sea Serum

As a beauty writer, I test skincare products regularly. Some offer near-flawless results, and some leave my acne-prone skin even more broken out than before. Even though I have a consistent skincare routine packed with anti-aging ingredients, my T-zone, furrow lines (between my brows), and smile lines have started to look more prominent. When I realized my once-vibrant skin looked dull and tired, I searched for a product to solve these skincare woes and landed on the Osea Hyaluronic Sea Serum.

The hyaluronic sea serum is packed with hyaluronic acid and Japanese miru seaweed. Both ingredients deeply hydrate the skin and leave it plump and rejuvenated.

Hyaluronic acid naturally occurs in the body and seals in moisture. Susan Weinkle, an assistant clinical professor of dermatology at the University of South Florida told Real Simple that "hyaluronic acid works by drawing in moisture to give your skin a smooth, and almost plumped-out appearance, making fine lines and wrinkles less prominent." She also explained that "when you hydrate the skin from outside, you make fine lines less noticeable."

After incorporating the serum into my daily routine for two weeks, my glow started to return. I was shocked that one serum actually provided results within a few weeks (typically, most products take at least a month). My skin maintained hydration, and my lines were smoother and less noticeable.

Shoppers praise the sea-inspired formula and call it "love at first application" and "amazing."

"[It's] magic in a bottle," another said. "I've tried tons of serums from clean beauty lines, and nothing compares to this product. It leaves my skin feeling super-soft and hydrated, and has noticeably reduced the excess oil on my skin."

A 29-year-old reviewer explained that fine lines and wrinkles were no match for the serum. "The morning after using the Hyaluronic Sea Serum for the first time, I could not stop touching my face—it was so smooth and plump," the shopper said. "I used this diligently over the holidays and when we returned from break, a co-worker stopped me in the middle of a conversation and asked if I had gotten Botox because my face just looked so youthful."

If your skin is sensitive, do yourself a favor and add the hyaluronic sea serum to your routine!
