What is OSEA? OSEA has been making organic, clean, natural seaweed-focused skincare since 1996. Malibu based and female founded, OSEA is also vegan, gluten-free and biodegradable. They blend their proprietary nutrient-rich organic seaweed concentrates with clean and vegan ingredients to create formulas that work well even for the most sensitive skin types.

The family-run brand is known for their luxurious spa-worthy yet still accessible line of sea-inspired skincare and body care, racking up numerous beauty awards over the years. While OSEA makes some fantastic spa-quality skincare and body care products, there is some controversy around the brand losing their original quality as they now mass manufacture their products to meet increasing demand. The best OSEA products are OSEA’s body care products (you can’t go wrong with any IMO), Atmosphere Protection Cream, Blemish Balm and Hyaluronic Sea Serum.

Read on for my OSEA review and which products I thought were hits and misses.

OSEA’s wild Gigartina seaweed is certified USDA organic and ecologically hand harvested in Patagonia, where it’s sun-dried on special drying beds. The OSEA team periodically goes and visits the seaweed they source in person! The Gigartina OSEA uses contains minerals, amino acids, antioxidants and trace elements that are super beneficial to our skin, stimulates collagen production, hydrates and soothes skin, and protects skin from environmental aggressors and stimulates cell regeneration.

OSEA has the cutest little spa in Venice Beach where you can get OSEA facials and body treatments. The OSEA Skincare Studio is conveniently right on Abbott Kinney Blvd. I’ve been and the staff are warm and attentive!

Hyaluronic Body Serum, Undaria Body Butter and Body Lotion!

OSEA’s natural body care products are soooo good! They really create beautiful, luxurious clean body lotions, oils and butters that are addictive to use. The new Hyaluronic Body Serum is a super lightweight, thin fluid with a serum consistency and feels totally weightless and refreshing on my skin!

It’s the perfect solution for people who don’t like the feeling of creams sitting on their skin. I’m super impressed that it acts like a skincare product and contains 5 molecular weights of hyaluronic acid, niacin amide, vegan peptides, blue-green algae, green microalgae and aloe.

The Undaria Algae Body Butter is a game changer for mature dry skin that needs serious moisturizing! It’s soooo creamy and nice and thick but not overly rich or heavy. Their Undaria Collagen Body Lotion is more of a runny lotion that feels like a serum, so the Body Butter is definitely my pick for deep hydration. The Undaria Body Butter and Undaria Collagen Body Lotion both have a fragrant sweet citrus scent that’s lovely for summer.

Collagen Dream Night Cream

I tested the new Collagen Dream Night Cream and find this to be a very hydrating face cream that gradually absorbs into the skin. It feels dense to the touch, like it would be a thick cream, but it actually goes on feeling light and hydrating. It has a light grayish purple hue and contains algae-derived bio retinol, vegan collagen, Pink Rock Rose Extract, Organic Wild Lavender and King of Bitters along with five vital hydrators. There’s also oat kernel flour and rice bran extract that makes it extra soothing. The scent is lightly citrus and herbal. This helps soften my skin and I feel that it keeps my skin well moisturized throughout the night especially during the winter while my heating is on blast.

Ingredients: Water / Aqua / Eau, Butyrospermum Parkii (Shea) Butter, Glycerin, Coco-Caprylate/Caprate, Diheptyl Succinate, Propanediol, Capryloyl Glycerin/Sebacic Acid Copolymer, Cetearyl Olivate, Squalane, Cetyl Stearate, Hydrogenated Starch Hydrolysate, Macadamia Ternifolia Seed Oil, Sorbitan Olivate, Behenyl Alcohol, Carthamus Tinctorius (Safflower) Seed Oil, Myristyl Myristate, Aphanizomenon Flos-aquae Extract, Cocoyl Hydrolyzed Collagen, Avena Sativa (Oat) Kernel Flour, Andrographis Paniculata Leaf Extract, Cistus Incanus Flower/Leaf/Stem Extract, Lavandula Hybrida Extract, Triheptanoin, Oryza Sativa (Rice) Bran Extract, Rosmarinus Officinalis (Rosemary) Leaf Extract, Helianthus

OSEA Ocean Cleanser

OSEA offers three different cleansers, each very different from the next. The OSEA Ocean Cleanser is agreeable for all skin types with a cream-gel consistency that gently removes surface debris and grime. There isn’t much foaming action but it does provide gentle cleansing thanks to its mild surfactant decyl glycoside. OSEA Ocean Cleanser works great as a second cleanse after makeup and sunscreen has been removed from a first cleanse. It has an uplifting citrus scent thanks to lime oil, orange oil, and juniper fruit oil.

Here’s what OBL reader ecoartsy says about OSEA’s Ocean Cleanser,

An absolute dream of a cleanser. This is a non lathering, hydrating, doesn’t strip the skin, and leaves my face feeling vibrant. This is a great cleanser if you wear minimal to no makeup. Great for men too! Highly recommend if you have combination skin or dry skin. The scent is absolutely a divine.

OSEA Ocean Cleansing Milk

If you’re wondering about the OSEA Ocean Cleanser vs Cleansing Milk, they’re very different from each other. If you’re looking for a milk cleanser, OSEA also makes a cleansing milk that’s creamy and hydrating. OSEA Cleansing Milk is great for those with sensitive skin who want a very hydrating cleanser. Seaweed is not as high in the list as with the OSEA Ocean Cleanser (which has seaweed as the second ingredients). For a milk cleanser, OSEA Cleansing Milk is still emollient with star ingredients like white water lily extract and safflower oil and melts into skin. I don’t find the cleansing power very strong with this cleanser either and prefer it as a second cleanse.

OSEA Atmosphere Protection Cream

The OSEA Atmosphere Protection Cream, along with their Blemish Balm, is a face moisturizer I often recommend to anyone asking for a good face moisturizer recommendation as it’s an all-around people pleaser. OSEA Atmosphere Protection Cream is a lightweight lotion-like cream that instantly makes skin feel softer and supple. There is no strong scent, except for a very subtle lavender scent.

OSEA Atmosphere Cream is fantastic for people who have sensitive skin and combo skin. It begins in a water base and is loaded with organic algae to help fend off environmental skin stressors, like sun, pollution, and dry climates.

OSEA Blemish Balm

The OSEA Blemish Balm is a super lightweight & fast-absorbing lotion balm that contains Organic Algae, Mineral Peptides and a blend of oil-balancing Tea Tree, Rosemary, Juniper, Cypress and Thyme essential oils to target blemishes and future breakouts, minimize the appearance of pores and oily shine, and soothe redness. Blemish Balm is lighter in consistency than Atmosphere Protection Cream as it’s formulated specifically for oily and acne-prone skin types. But even with my dry and combo skin, I still really liked this cream.

OSEA Hyaluronic Sea Serum

One of the best organic hyaluronic acid serums available, OSEA Hyaluronic Sea Serum is a luxurious hydrating serum harnessing the powers of both sea and science. Hyaluronic Sea Serum contains 3 molecular weights of hyaluronic acid which attracts up to 1,000 X its weight in water, strengthening the skin’s moisture barrier for visibly improved firmness & elasticity. It doesn’t end there though. What sets Hyaluronic Sea Serum apart from any other Hyaluronic acid serum is these three hyaluronic acid weights work synergistically with three organic Seaweeds.

Hyaluronic Sea Serum has a viscous consistency, almost like a bouncy water gel. Because Hyaluronic Sea Serum is quite a dense serum, one drop on each cheek is enough to spread over my unusually large face. My skin feels plump and hydrated after using OSEA. Its only downside is the price can be prohibitive at $88.

OSEA Sea Vitamin Boost

OSEA face mists are a popular favorite and it’s easy to see why. OSEA Sea Vitamin Boost comes in a huge heavy glass bottle (full size) and contains antioxidant-rich seaweed including Red Seaweed, their signature Gigartina seaweed and Pomegranate to hydrate and protect skin. OSEA Sea Vitamin Boost has a very delicate almost undetectable berry scent to it.

OSEA Anti-aging Body Balm

The luxurious OSEA Body Balm is a salve consistency that you’re either going to loveor hate. Most people are used to either using a body lotion and/or body oil, so a body balm might not be pleasant for everyone. But if you suffer some dry skin and need something heavier than a body lotion but don’t want a full-on body oil, the OSEA Body Balm is a happy medium. It has an uplifting citrus scent that isn’t overpowering and sinks in best on wet skin immediately after a shower.

OSEA Salts of the Earth Body Scrub

The OSEA Salt of the Earth Body Scrub is a beautiful, luxurious body scrub product. Depending on how much you use per bath, it can last a handful of uses. For me it has an ideal scrub to oil ratio as I’ve used body scrub jars that would contain too much oil and felt greasy in-bath.

OSEA White Algae Mask

OSEA White Algae Mask does not contain any clays but instead gives my skin a boost of nutrients before applying skincare. It contains White Marine Algae, White Tea and Resveratrol to diminish the appearance of surface redness, and Mineral Peptides and Hyaluronic Acid to lock in hydration. This mask won’t give you a major brightening/plumping effect if that’s what you’re looking for but it will feed your skin vitamins & antioxidants and leave it visibly toned.

OSEA Red Algae Mask

The Red Algae Mask (normal to combo skin) removes surface impurities and minimizes the look of pores for a visibly refined complexion. Though my skin can be sensitive I would not consider it to be truly sensitive and this mask was almost a little too powerful for my skin. I can feel a slight burning so I leave it on the for the minimal amount of time (10 mins) and rinse it off. As with all masks I try to do it either in or after a shower or after a steaming session for the mask to work its full potential.

OSEA Vitamin C Probiotic Polish

The OSEA Vitamin C Probiotic Polish provides manual exfoliation and a visible brightening effect that does not leave you questioning its effectiveness (no surprise as the first ingredient is Ascorbic Acid).

It is the first product to combine pure Vitamin C with vegan probiotics and contains Fermented Pomegranate enzymes to gently remove surface build-up, and finely ground organic Bamboo and Rice powders infused with mineral-rich Seaweeds to delicately buff away dull skin. Despite its great qualities, the OSEA Vitamin C Polish isn’t one of my top favorites as the particles feel abrasive on my skin. You also need to make sure to use this product quickly as the Vitamin C will oxidize otherwise. You’ll be able to tell because the color will change to a darker shade.

OSEA Essential Corrective Complex

OSEA makes their very own pimple potion aka oil serum called Essential Corrective Complex. It’s best used as a spot treatment not as an everyday face oil. Essential Corrective Complex contains tea tree, white thyme and juniper to deliver a non drying complex that reduces blemish-causing oils and impurities. It comes in a small rollerball applicator that tends to dispense a lot of product. I’ve tested Essential Corrective Complex on my hormonal zits and they seemed to help, and to get a second opinion I asked a friend who gets pretty severe pimples to test it as well and he felt that the product helped.
