If there’s one thing we’re serious about, it’s our bedtime routine, and for good reason. Sleep gives your skin, body and mind the chance to reset, and when we don’t get enough of it, the signs show up fast (think dullness, dryness and a loss of elasticity). One of the most effective ways to give your skin a rest is by creating a consistent overnight skincare ritual. This one layers nourishing, seaweed-powered face and body care that feels as soothing as it is effective. Ahead, discover your six-step nighttime routine for more rested, radiant-looking skin by morning.
Step 1: Wash Away the Day
Cleansing is the cornerstone of any skincare ritual. Not only does it lift away makeup, impurities and buildup, it also helps the rest of your products absorb more efficiently. Begin by stepping into a warm, indulgent shower and letting the therapeutic pressure of the water cascade over your neck, back and shoulders. It’s the perfect moment to slow down and reset. Give your face a gentle massage as you work our seaweed-powered Ocean Cleanser into your skin, leaving it soft, hydrated and refreshed. Then lather neck to toes with our Undaria Algae™ Body Wash. This pH-balanced daily nourishing cleanser is made with Undaria seaweed and uses a plant-based surfactant blend to provide a gentler cleansing experience without drying or stripping. A few times a week, reach for our Undaria Cleansing Body Polish, crafted with kiwi AHA–infused rice microparticles to physically and chemically exfoliate for healthy-looking skin. The uplifting notes of grapefruit, cypress and sweet mango mandarin in both formulas turn your shower into a tropical escape.
Step 2: Treat Your Body
Get ready to drift off to your dream skin. After toweling off, smooth on a generous amount of our Dream Bio-Retinol Body Serum from the neck down. This dreamy, creamy bedtime 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 sleep. In an independent third-party clinical study, 100% showed improvement in skin firmness after 4 weeks*. The unique milky formula has a creamy yet lightweight texture that absorbs quickly and blankets skin in nurturing care. Lavender soothes and promotes a sense of serenity for a restful night, while magnesium helps skin feel soothed for a rested, revitalized look. Wellness while you sleep.
Top it off with your favorite OSEA body moisturizer, such as our bestselling and award-winning Undaria Algae™ Body Oil to maximize your skincare benefits. Made with nourishing hand-harvested Undaria seaweed, rich in amino acids, antioxidants and nutrients to replenish the skin’s moisture barrier, our award-winning body oil is clinically shown to improve skin elasticity after one use**. We love how the iconic, uplifting citrusy scent pairs beautifully with the dreamy lavender in our Body Serum and lingers subtly on skin. You can use each product on its own, but together they deliver silky-soft, visibly firm, ultra-moisturized, glowing skin—all over.

Step 3: Exfoliate Your Face
Twice a week, apply a thin layer of our Seaglow Overnight Serum AHA Treatment to your face before tucking yourself into bed for a beautiful night’s rest. This multi-acid blend uses over 11% AHAs, phytic acid and tropical fruit extracts to exfoliate while you sleep, as a nourishing blend of red algae, spirulina and fermented shiunko oil supports the skin’s moisture barrier. Wake to clearer pores and smoother, brighter-looking skin.
Step 4: Dream Serum & Face Moisturizer
Sleep gives our skin the chance to renew, and the right skincare can play a big role in that. Say goodnight to wrinkles with Dream Night Serum with Bio-Retinol, our most advanced wrinkle-smoothing formula yet. This powerful serum works overnight to visibly reduce crow’s feet, fine lines, wrinkles and even deep wrinkles while you sleep. Powered by the same algae-derived bio-retinol you know and love from the other products in our Dream Collection, along with two firming peptides, it mimics the effects of retinol without the irritation, making it a game-changer for all skin types.
No nighttime skincare routine is complete without a nourishing moisturizer. Not only will this step seal in the goodness of your serum, but the best one will help you wake up looking radiant, rested and refreshed by morning. Like the other products in our Dream Collection, our Dream Night Cream with Bio-Retinol visibly firms and smooths fine lines and wrinkles. But it goes one step further. Inspired by psychodermatology, a field that explores the link between the mind and skin, our innovation is the first night cream clinically shown to reduce the visible effects of stress on the skin*. In clinical testing, Dream Night Cream was shown to visibly firm skin and visibly reduce dark circles in just two weeks*. So can a less stressed, more peaceful mind really transform your skin? In the case of our overnight moisturizer, the answer is a resounding yes.

Step 5: Set the Vibe
Now that your skin and body have been cared for, it’s time to set the vibes for bed. We love to unwind with our Vagus Nerve Collection to promote a sense of well-being before sleep. Apply a few drops of our soothing Vagus Nerve Oil to the sides of your neck and spritz your linens with our Vagus Nerve Pillow Mist to envelop the senses in tranquility as you unwind. A soothing essential oil blend of chamomile, juniper berry, lavender, lemon tea tree and Moroccan rosemary melts away visible signs of stress to help balance the mind and body. Take a few deep inhalations, lay your head down and drift off to your best night’s sleep.
