Summer is in full swing, and the sun is shining bright. It’s the season of picnics in the park, beach trips and vacations. But while you’re soaking up those golden rays, your skin may be craving hydration. When it comes to summer skincare, hyaluronic acid is the key to dewy, hydrated, healthy skin from top to toes. Say hello to our bestselling lightweight hyaluronic acid hydrators for face and body that you’ll use to the very last drop.
What Is Hyaluronic Acid?
First things first. Hyaluronic Acid (often referred to as HA) isn’t really an acid. It’s actually a carbohydrate, or sugar, that naturally occurs all over the body, including in our skin and joints. Known for being a humectant (a substance that will draw and hold onto water), it plays a huge role in retaining moisture. Hyaluronic acid pulls moisture in from the environment and your other skincare products and locks it in to help replenish water levels in your skin and reduce transepidermal water loss (TEWL). Both age and the environment (for example, extreme heat) can impact the amount of natural hyaluronic acid in our skin. This is one of the reasons we start to see less firmness and plumpness in our skin over time.
Hyaluronic Acid in Skincare
Luckily, it’s an ingredient that can be replenished topically by skincare. It can be used by pretty much everyone, no matter the age or skin type. We formulate our products with low and high molecular weight hyaluronic acid. Low molecular weight can penetrate deeper into the skin, giving it a visible plumpness, while high weight hyaluronic acid sits on top of the epidermis, drenching the driest layers in hydration and delivering a dewy glow. A combination of low and high weight hyaluronic acid helps maximize moisture on every level. Here’s how to add it to your summer skincare routine for your most hydrated skin yet.
Our Favorite Hyaluronic Acid Products
Hyaluronic Sea Serum
We swear by this summertime staple for dewy, hydrated, glasslike skin. But what exactly makes our bestselling Hyaluronic Sea Serum so great? It uses two different types of hyaluronic acid—one high molecular weight, one low—to synergistically boost hydration, fullness and firmness of the skin. There’s also Japanese Miru seaweed to replenish and balance the skin’s natural hydration levels, as well as snow mushroom (Tremella fuciformis), which acts as both a humectant and an emollient, drawing water to the skin, then sealing it in for a more bouncy, plump look. The remarkable clinical results speak for themselves. In a third-party study, 100% of participants showed an immediate increase in hydration.* It’s also clinically shown to strengthen the skin’s moisture barrier and help skin retain essential hydration.* And after just two weeks, the appearance of lines and wrinkles is minimized.* Brilliant!
Seabiotic® Water Cream
All skin types benefit from extra hyaluronic acid hydration even when it’s hot and humid out. Look for lighter textures like our Seabiotic® Water Cream to smooth, refresh, and plump the look of your skin. This microbiome-friendly formula is practically weightless yet somehow still manages to hydrate for 72+ hours* (it’s clinically tested!). It’s also clinically shown to instantly increase skin hydration by 173%.* The secret lies in a combination of powerhouse ingredients, including Undaria seaweed, which replenishes the skin’s moisture barrier, and plant-based squalane, an emollient that provides lightweight and long-lasting moisturization. The gel-cream texture feels cooling, and the burst of hydration is incredibly refreshing on sun-drenched days. Massage it on first thing in the morning over your Hyaluronic Sea Serum and at the end of the day for a silky-smooth, dewy finish.
Ocean Eyes® Serum
Nothing says vacation skin like bright, hydrated, wide-awake eyes. Our award-winning Ocean Eyes® Serum achieves all that and more. Seconds after you roll it on, this powerful eye treatment wakes up your entire face. It deposits all of its visibly brightening, firming, depuffing, wrinkle-smoothing, and hydrating ingredients (including hyaluronic acid, seaweed, a biomimetic peptide, and clinically-tested quinoa extract) through a rollerball that cools skin on contact and makes you look noticeably refreshed (with or without makeup). Shown to deliver remarkable results, 97% of users said their skin looked more awake, smoother, and firmer after 2 weeks,** and 94% users said it reduced undereye bags and puffiness after 4 weeks.** Apply it morning and night and be amazed by the fresh-faced transformation. Plus, it’s completely scent and fragrance-free, so you can roll it on with abandon. The results build over time, so reach for it at least once a day and keep at it.
Hyaluronic Body Serum
Think of our ultra-hydrating gel-like body serum as a cooling rehydration elixir for your entire body. This lightweight serum gets to work and sinks in instantly – so you can apply, enjoy, and get on with your summer plans. Hyaluronic Body Serum is clinically shown to instantly boost hydration and improve the skin’s natural moisture barrier* for visibly healthy, smooth skin everywhere. Packed with five molecular weights of hyaluronic acid, aloe, vegan peptides and nutrient-dense seaweed, this full-body treatment delivers 24 hours of multi-surface hydration.* Use it after a day in the sun to replenish moisture and to give your skin – and you – a new lease on life. The results? Soft, smooth, ultra-hydrated skin.
Undaria Algae™ Body Lotion
One of the most important elements of our summer body care routines—whether we’re on the sun-drenched Malibu coast or exploring the drizzling Pacific Northwest—is sunscreen and moisturizing our bodies every single day. In the summer, we prefer lightweight hyaluronic acid hydration with our bestselling Undaria Algae™ Body Lotion. This silky body lotion is just the ticket for soft, glowing limbs without the stickiness. Hard-working hydrators, including hyaluronic acid, glycerin, jojoba oil, and avocado oil, sink in instantly, leaving nothing behind but the prettiest sheen and healthy-looking skin. We love that it comes in our iconic Undaria citrusy scent or in fragrance-free (for sensitive skin). The best part? It’s clinically shown to immediately increase hydration and visibly firm skin in just four hours.*
