Our First Bio-Retinol Serum
Friends, this has been a long time coming. We’re so excited to introduce Dream Night Serum with Bio-Retinol, our latest innovation. This powerful seaweed-infused formula combines algae-derived bio-retinol with two firming peptides to visibly reduce crow’s feet, fine lines, wrinkles and even deep wrinkles overnight. It’s beauty sleep in a bottle, for real! Here’s everything you need to know about this game-changing serum and how to use it for visibly smoother, youthful-looking skin.
Say Goodnight to Wrinkles
No matter your age, ethnicity, gender, or skin type, wrinkles happen to everyone. Dream Night Serum with Bio-Retinol targets the four main types of wrinkles that appear naturally as we age. Those small creases along our foreheads and at the corners of our eyes are a natural part of the human experience and they can surface as early as your 20s. Whether you’re seeing the first signs of expression lines, dealing with deep-set creases, or noticing a loss of firmness, this potent serum has you covered.
Sea the Difference at Every Age
Effective for all skin types—even sensitive—Dream Night Serum with Bio-Retinol is designed to work at every age, and every stage of life—from your 20s to your 60s and beyond. And here comes the science: fine lines start surfacing in your 20s and 30s from years of laughter and expression. By your 40s, deeper creases begin to set in as collagen levels drop. In your 50s and beyond, gravity takes its toll, leading to sagging and more pronounced wrinkles. No matter where you are in your skincare journey, our powerhouse formula works overnight—and over time—so you wake up feeling refreshed, confident and naturally radiant.
What Makes It So Effective?
As with all our formulas, the secret lies in the clean, clinically tested ingredients inside. And in this case, it’s about a few powerhouses that have been expertly extracted—ensuring we get the best of every drop.
First up is bio-retinol—a potent extract from green microalgae. Just like in our cult-favorite Dream Night Cream, bio-retinol acts as a safe, stable alternative to retinol and visibly improves lines, wrinkles, and skin firmness—without irritation. Next, sustainably sourced red seaweed—aka Jania rubens—combines with two firming peptides (tripeptide and tetrapeptide) to smooth the look of fine lines and wrinkles, while hydrolyzed hyaluronic acid visibly reduces the appearance of deep wrinkles. Along with its serious potency, the visible results—especially for deep wrinkles—really set our new serum apart.
Bio-Retinol vs Retinol
The gold standard ingredient in skincare, retinol can make a profound difference in your skin—if—and that’s a big “if”—you’re able to tolerate it. Retinol, a derivative of vitamin A, works by boosting cellular turnover and helping support collagen production. But even if your skin is pretty robust, there’s often a several-month “build-up” period where you might experience redness, burning, itching, purging, peeling, and dryness. And if you have sensitive skin, you’re more susceptible to these kinds of reactions.
The beauty of Dream Night Serum is that it harnesses the power of clinically backed, algae-derived bio-retinol to mimic the effects of retinol—improving the visible signs of aging and the appearance of fine lines, wrinkles, and deep wrinkles—without irritation.
Although designed for nightly use, it’s gentle enough for both morning and night—unlike regular retinol, which is typically limited to nighttime and may require spacing out throughout the week. Plus, there’s no need to worry about sun sensitivity, though SPF is always a must during the day!
Finally, unlike with retinol, you can seamlessly layer Dream Night Serum with your favorite vitamin C treatment, BHA, or AHA (like our Seaglow Resurfacing Serum) as part of your PM routine—meaning you don’t have to overthink or overschedule when you apply your skincare.
