PSA: Using a body moisturizer is non-negotiable. But does the perfect body moisturizer even exist? And how do you choose the best one for you? Much like the skincare you use on your face, body moisturizers come in a variety of formulations meant to target different concerns, such as dryness, loss of elasticity, firmness, and other signs of aging. Ahead, discover our bestselling body care moisturizers for every skin type, mood, and need.
The Ultimate Hydrator
Hyaluronic Body Serum
Lightweight and fast-absorbing, our ultra-hydrating daily treatment instantly improves the skin’s natural moisture barrier.* Packed with 5 molecular weights of hyaluronic acid, niacinamide, vegan peptides, blue-green algae and aloe, it melts right into skin, without leaving any sticky or tacky residue behind. Don't be fooled by the lightweight texture––this gel-like serum is clinically shown to instantly increase hydration by 161%* and delivers 24 hours of non-stop moisture.* The results? Soft, smooth, healthy-looking skin.
Our body serum is designed to be layered first, followed by your favorite body moisturizer (think lotion, body butter, balm or oil) to maximize results and lock in moisture. However, for some skin types the intense hydration it provides may be all you need.
The Overnight Firming Treatment
Dream Bio-Retinol Body Serum
Meet your new bedtime body treatment. This dreamy, creamy serum, formulated with a holistic blend of algae-derived bio-retinol + red seaweed, visibly firms, smooths the look of lines and wrinkles on the body, hydrates, improves elasticity and boosts radiance—all while you sleep. This isn’t your typical 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. Infused with magnesium to soothe and lavender to promote a sense of serenity for a restful night, this restorative formula is the ultimate wind-down ritual for your whole body. The unique milky formula has a creamy yet lightweight texture that absorbs quickly and blankets skin in soothing care.
The Glowiest
Undaria Algae™ Body Oil
We dare you not to feel like a glowy goddess when you put this on. Our bestselling body oil combines seven botanical oils, including açaí and sunflower, with nutrient-rich Undaria seaweed for silky-soft, incredibly glowing skin. This gorgeous golden elixir is the color of sunshine and smells like a citrusy vacation. Even the most devoted body lotion lovers will fall for our non-greasy, fast-absorbing oil. We promise it passes the get-dressed test with no waiting period, so you can slip right into your skinny jeans or tuck yourself into your crisp white sheets right after applying.
The Age-Defier
Undaria Algae™ Body Butter
That rare person who doesn’t have at least some dry patches, crepey parts and loss of elasticity on their body can ignore the following, but for everyone else, there’s our age-defying body butter. Ultra-rich and utterly moisturizing, this beautifully dense cream transforms dry, crepey skin to soft, smooth and supple. Fast absorbing? Check. Clinically shown to hydrate for 72 hours? Check. High-performance, skincare-level ingredients, like firming amino acid DPHP, seaweed, ceramides and whipped shea butter? You bet! Factor in the buttery-rich texture and cheerful grapefruit and mandarin scent and you’ve got yourself a real winner.
The Ultra-Rich
Anti-Aging Body Balm
If your skin is extra dry, consider our intensely moisturizing lotion-and-serum hybrid the magic fix. This silky, youth-restoring liquid balm sinks right in, nourishing thirsty skin and leaving only super-supple, radiant skin behind. Coconut oil, passion fruit, Alaria esculenta seaweed, omega fatty acids, minerals and antioxidants are all packed into one softening, smoothing and heavenly formula. Inhale the addictive floral jasmine-and-geranium scent and you’ll wonder how you ever lived without it.
The Lightweight
Undaria Algae™ Body Lotion
For those seeking a lighter option, we’ve got just the thing. Our fast-absorbing Undaria Algae™ Body Lotion leaves skin nourished and hydrated without any heaviness. This milky concoction, loaded with hyaluronic acid, Undaria seaweed and peptides, sinks effortlessly into skin, locking in hydration and drying down quickly to leave nothing behind but velvety softness. The best part? It’s clinically shown to immediately increase hydration and visibly firm skin in just four hours.* Plus, it leaves your skin feeling exceptionally smooth and luminous.
