We all know bio-retinol as the gold standard for smoothing your skin without irritation, but it isn’t just for your face anymore. Get ready to drift off to your dream skin for visibly firmer, smoother skin—everywhere.
Your Skin’s Best Night Sleep
Introducing Dream Bio-Retinol Body Serum, your new overnight firming treatment, and the latest member of The Dream Collection family. This dreamy, creamy treatment, formulated with a holistic blend of algae-derived bio-retinol + red seaweed visibly firms, smooths the look of lines and wrinkles (on your body), hydrates, improves elasticity and boosts radiance—all while you dream. This isn’t your ordinary bio-retinol product; it’s the first-of-its kind body serum designed to target the visible effects of stress on skin, including lack of firmness, dullness and dryness. And the results don’t stop there. This restorative formula infused with magnesium and lavender actually helps promote a sense of serenity for a restful night.
Put Stress to Bed
Once upon a time, someone somewhere created the phrase ‘beauty sleep’, and for good reason. Stress and sleep deprivation can both weaken the skin barrier and slow its ability to repair itself.¹ The rate at which our skin cells regenerate almost doubles at night, meaning that as we sleep our cells are primed to rebuild themselves.² But when we’re stressed, our sleep suffers—and so does our skin’s ability to bounce back.
On top of that, our body care routines can be an added stress on skin, with products that contain harsh actives like certain acids, retinol, and vitamin C that can irritate in the name of overnight results. Even if your body skin is pretty robust, there’s often a “break-in” period with ingredients like retinol where you may experience redness, peeling, or purging. If you have sensitive skin, then you are more susceptible to these kinds of reactions. Our new body serum uses a proprietary blend of algae-derived bio-retinol and red seaweed to mimic the firming, line-smoothing effects of retinol with less potential for irritation. It puts stress to bed so you can wake up to softer, smoother, more radiant skin.
Dreamy, Creamy, Lavender Milk Serum
Dream Bio-Retinol Body Serum is the epitome of wellness while you sleep, featuring a subtle lavender scent that soothes the senses. The unique milky formula has a creamy yet lightweight texture that absorbs quickly and blankets skin in soothing care.
Sea Results Overnight & Over Time
We like to think of our Dream Bio-Retinol Body Serum as a good night’s sleep bottled. But it was important that our community think the same thing. So a lot of testing had to happen to get the formula just right.
First, we did independent third-party clinical trials that measured firmness, smoothness and fine lines and wrinkles in the skin over time. Dream Bio-Retinol Body Serum was clinically tested to improve these visible signs of aging after 4 weeks**. It was also clinically shown to increase hydration overnight, as you sleep*.
Then we did consumer studies – which means 30 women applied the body serum for one week. And it delivered on the skin and sensory benefits unique to this product, including being non-irritating, soothing skin as you sleep and having a calming scent.**
Clinical Results*
After 1 use:
• 100% showed an increase in skin hydration
After 4 weeks:
• 100% showed improvement in skin firmness
• 87% showed visible improvement in skin smoothness
• 83% showed visible improvement in fine lines and wrinkles
Consumer Results*
After 1 week:
• 100% agreed it is gentle and non-irritating
• 100% agreed the lavender scent is calming and relaxing
• 90% agreed it soothed my skin as I slept
*Based on an independent third-party clinical and consumer-perception study conducted on 30 women.
Clean Ingredients for Dreamy Skin
All of our face and body-care formulas combine pure, potent seaweed with active botanicals for clinically tested results you can sea and feel. Dream Bio-Retinol Body Serum’s formula is no different. But this time, the sensorial experience goes one step further—by visibly de-stressing skin and promoting a sense of serenity while you sleep. Here’s how we did it…
Bio-Retinol + Red Seaweed
Our bio-retinol is a potent marine extract derived from green microalgae. Sustainably sourced and wild-harvested from the pristine Klamath Lake in Oregon, a volcanic glacial-fed body of water, it’s packed with naturally occurring amino acids, vitamins, antioxidants and phycocyanin. The bio-retinol we use acts as a safer, stable alternative to retinol. When combined with our red seaweed, it visibly firms and smooths the look of lines and wrinkles without irritation. The beautiful thing about our bio-retinol is that there’s no need to start slowly, like you would with traditional retinol, or avoid specific ingredients (like your favorite AHAs and BHAs). It’s even well-tolerated on sensitive skin.
Magnesium & Lavender
These two potent ingredients work in tandem to soothe and help promote a sense of serenity for a restful night. Lavender is renowned for its comforting properties, while magnesium helps skin feel soothed and replenished to support a rested, revitalized look.
Hyaluronic Acid
Hyaluronic acid (HA) is a powerful humectant that attracts water and delivers moisture to the skin. The hyaluronic acid in this formula nourishes skin with hydration and visibly improves elasticity.
Niacinamide
This powerhouse, multitasking vitamin helps visibly boost radiance.
Your New Evening Body-Care Routine
Now we get to the good stuff. How to use Dream Bio-Retinol Body Serum, when to use it, and how much to use.
As the name suggests, Dream Bio-Retinol Body Serum is designed to be used before bed each night. For next-level beauty sleep, we recommend using it along with the other products in our clean body-care line for round-the-clock results, but it can also fit seamlessly into your existing routine.
Cleanse
Start your bedtime routine with our Undaria Algae™ Body Wash. This pH-balanced daily nourishing cleanser is made with Undaria seaweed and uses a natural, plant-based surfactant blend (aka–cleansing agent) to provide a gentler cleansing experience without drying or stripping.
Exfoliate
Next up is body exfoliation. Just about everyone’s skin benefits from both physical and chemical exfoliation. Our Undaria Cleansing Body Polish delivers the benefits of both in the form of kiwi AHA-infused rice microparticles, instantly polishing away roughness, smoothing bumpy texture, and revealing soft, glowing skin.
Treat
And now for the main event. After toweling off, smooth a generous amount of our new Dream Bio-Retinol Body Serum from the neck down. Use it alone, or wait until the product absorbs and follow with your favorite OSEA body moisturizer, such as our bestselling Undaria Algae™ Body Oil to maximize your skincare benefits, and for a moisturized, full-body glow. Then slip between your crisp sheets as cozy, soft and comforted as can be.
