Pricey for a body butter

What the gurus are saying

This butter melts beautifully into skin but spreads more easily when applied to damp rather than bone-dry skin, so it's best applied right after the shower. It delivers all-day moisture without feeling heavy or greasy, making it ideal for anyone with dry or flaky skin. The undaria seaweed, ceramides, and shea butter combine to strengthen the skin barrier.

"I've been using the OSEA Undaria Algae Body Butter [...] on and off for several years. Anytime I want another body butter in my routine, [...] this is always the one I'll repurchase because it truly acts like a real body butter, it's thick, rich, and very moisturizing on the skin. If you have dry, flaky, parched skin you are going to love this, I guarantee it."

"My body cream pick is the OSEA Undaria Algae Body Butter. I did OSEA as a brand review a few years ago and it was a disaster for my face, but [...] I ended up finding some fantastic body care from that brand. Body skin isn't as delicate as facial skin for the vast majority of people, so it's got essential oils in it, but that's not going to bother most people."

"This stuff is nice. Osea as a whole, I tried them a while ago and I didn't love their skin care products, but I did love their body care. It's expensive, 56 dollars for a body butter, but if you do love it, get it for 28 instead of 56 in the sale. It is nice, it is a very nice body butter."

"I'm a huge OSEA fan and I love their body products. This body butter is so good. [...] I love the texture of it, it melts into the skin and it's so rich and luxurious. It has the same smell as the body oil, so if you're into that, that gives you an idea of what to expect with this."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.

Vitamin E

Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
