I Used OSEA's Hyaluronic Body Serum For 3 Months & My Skin Is Visibly Smoother

Earlier this year, I started using a hyaluronic acid serum on my face, and I was shocked by how quickly my skin started to look plumper, softer, and younger.

The only problem? I’ve been neglecting the rest of my body.

You see, hyaluronic acid (HA) is a key molecule in skin hydration—and the body loses about half of its natural reserve by the time we hit 50. 

I’m 35, so I don’t have a ton of wrinkles yet, but I have noticed my skin isn’t quite as bouncy as it used to be.

My legs and arms look and feel drier than they did in my twenties, and I see fine lines popping up around my elbows, knees, neck, and chest.

Like all OSEA products, this serum is vegan and cruelty-free. It’s made without parabens, sulfates, heavy metals, or synthetic fragrances.

The serum’s hero ingredient is hyaluronic acid, a high-performance humectant that’s like a magnet for hydration. Basically, it pulls moisture into your skin—so it's well-loved for plumping and smoothing fine lines and wrinkles.

OSEA’s Hyaluronic Body Serum formula also contains niacinamide (vitamin B3), which hydrates and smooths the skin, vegan peptides to nourish and plump, blue-green algae to replenish essential minerals, and aloe to support the skin’s natural moisture barrier.

Translation: It’s a hydration powerhouse. 

I apply the serum on clean, dry (or damp!) skin, and my body drinks it up. In the morning, I use the serum on its own, but at night I layer on a body lotion and an oil afterward (to maximize the benefits).

I love that the lightweight serum absorbs quickly and isn’t at all sticky. Plus, a little bit goes a long way. 

I've never had that “glass” skin look on my body, and I assumed I simply wasn’t born with it. But three months with this serum proved otherwise. 

It only took a few applications for my arms and legs to start looking smoother—and more recently, I’ve noticed I have far fewer fine lines in those aforementioned “problem” areas. 

I’m just one reviewer, but the brand also has research to prove the results. In a third-party study, participants saw a 161% instant boost of hydration and an instant improvement in the skin’s natural barrier after just one use.

Plus, this serum has over 500 people singing its praises. 

OSEA’s Hyaluronic Body Serum instantly smooths, plumps, and hydrates my skin—and my fine lines are fading after just three months. Plus, I love knowing I’m using clean, science-backed ingredients to support my skin’s longevity.
