I tested 20 OSEA bestsellers and am sharing what I liked and didn’t like. OSEA has been making organic, clean, natural seaweed-focused skincare since 1996. They’re vegan, gluten-free and biodegradable and focus on their proprietary nutrient-rich organic seaweed concentrates.

OSEA’s wild Gigartina seaweed is certified USDA organic and ecologically hand harvested in Patagonia, where it’s sun-dried on special drying beds. It’s chock full of 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.

Also if you’re in the Los Angeles area, OSEA has the cutest little spa in Venice Beach where you can get OSEA facials and body treatments. I’ve been there and the staff are warm and attentive!

I tried OSEA Ocean Eyes Age-Defying Serum

This eye serum feels super refreshing and cooling thanks to metal roller ball applicator. The serum is actually a liquid and feels super duper light. I consider this a hydrating boost for the eyes that’s great if you don’t like eye creams. I wouldn’t consider this a heavy duty eye product that can tackle serious signs of aging like deep wrinkles. I love that it’s still got plenty of actives like Undaria and red algae, Caffeine, hyaluronic acid, biomimetic tetrapeptide, and a bark and plant extract. Personally this isn’t something I’d use for my mid 30s skin but I probably would have liked it in my 20s!

Best for: dark circles, fine lines, puffiness and crow’s feet
Price: $58

I tried Undaria Algae Body Wash

I tried OSEA’s new body wash and it has been perfect to use this summer. It’s got their signature sweet citrus scent. I’d say the scent power is impactful but not too strong nor subtle. It’s got a light hydrating gel consistency but there isn’t much suds action going on here. So I’d say it’s great for a light cleanse but for lots of soapy action I’d skip this one. On the plus side, it doesn’t strip my skin at all. I love that it’s pH balanced and is full of aloe and glycerin to hydrate the skin barrier. Since it’s got the same scent as my other undaria algae body products like the body lotion and body oil, I don’t have to experience any annoying scent clash.

Price: $32 for 8 oz

I tried Undaria Algae Body Butter, Anti-Aging Body Balm, Hyaluronic Body Serum, Body Oil 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. They both have a fragrant sweet citrus scent that’s lovely for summer. The Undaria Algae Body Oil is also a perfect body oil with a light and hydrating consistency that deeply moisturizes.

I know the Anti-Aging Body Balm is one of OSEA’s top selling products, but this one is bit of a miss for me. It’s got a unique salve consistency that you’re either going to love or hate. I’m not a fan of the residue it leaves behind. 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, this *could* be a happy medium. It has an uplifting citrus scent that isn’t overpowering and sinks in best on wet skin immediately after a shower.

I tried 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.

I tried Salts of the Earth Body Scrub

This is a very moisturizing kind of body scrub, so if you need something heavy duty that actually scrubs, I’d skip this one. Otherwise, I do love that it’s full of Gigartina Seaweed, a mineral salts blend, shea butter, rice bran extract, safflower seed oil and lavender oil. I’ve gotten around 6 uses out of this one jar. It leaves my skin soft and super moisturized after.

Price: $48 for 12 oz

I tried Dream Night Serum with Bio Retinol

I always update this post with the newest OSEA products I test out and I recently finished up a bottle of their Dream Night Serum. This is a nighttime use only product that contains algae-derived retinol to help with lines and wrinkles. It’s a lot lighter in consistency than their Hyaluronic Sea Serum and absorbs quickly. I love that it has their signature Red Seaweed, two types of firming peptides, hydrolyzed hyaluronic acid and an extract derived from green micro algae that mimics the effects of retinol. Do I think it’s as strong as my actual retinoids? No, I’ve got a whole guide to clean retinol. This is definitely a gentler kind of product that I don’t feel is nearly as heavy duty as others I’ve tried. With that being said, I don’t feel it’s worth the $88 price tag for what it is, unless something super gentle is what you’re after. For this amount, I’d rather invest in a more clinically advanced retinol serum.

I tried Ocean Cleanser

I’ve gone through multiple bottles of Ocean Cleanser over the years, so that’s saying something! It’s great 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. 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.

I tried Atmosphere Protection Cream

The OSEA Atmosphere Protection Cream, along with their Blemish Balm, is 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. This 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.

I have an entire guide to natural face moisturizers.

I tried Blemish Balm

The Blemish Balm is my top favorite out of all of OSEA’s face creams! I find it to be 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.

I tried Hyaluronic Sea Serum

This is one of the best clean hyaluronic acid serums on the market though it is quite pricey. It contains 3 molecular weights of hyaluronic acid which attracts up to 1,000 X its weight in water. What sets this serum apart from any other is the three hyaluronic acid weights working synergistically with three organic Seaweeds. It has a viscous consistency, almost like a bouncy water gel. Because this 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.

I Tried OSEA Seaglow Resurfacing Scrub

I was surprised by just how creamy OSEA’s mask is, so this is a great option for dry and sensitive skin individuals. I would consider this a gentle exfoliating scrub that can double as a hydrating mask. This is a beautifully formulated ocean-inspired cream gel hybrid mask with a variety of physical exfoliants from the ocean like sea silting volcanic sand along with innovative chemical exfoliants like flower acids and Kiwi AHA Infused Rice Microparticles. My skin looks and feels much more clarified after using OSEA’s scrub and not at all dry or irritated. I would recommend this for those who have damaged skin barriers, but not for those who need intense exfoliation.

Price: $58 for 1.7 oz
Strength: Gentle
Method: Chemical (flower acids) and physical (ocean particles)

I tried Sea Vitamin Boost

Sadly, I don’t feel that OSEA’s face mists are worth the buy and I personally wouldn’t repurchase these. It 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. It’s got a very delicate almost undetectable berry scent to it. The formula just feels too watered down to me compared to other natural toners.

I tried Vagus Nerve Bath Oil

I love a good bath oil and anything to do with healing my vagus nerve, so I have a soft spot for this product. It’s got a heavenly scent of chamomile, lavender and juniper that’s so soothing and not at all overpowering. It’s super moisturizing so I have to be careful not to pour too much into my bath. I love that it’s got a decadent blend of apricot, avocado, grapeseed, jojoba seed and meadowfoam seed oils as well as Moroccan rosemary to help soften skin and destress the mind.

Price: $48 for 5 oz

I tried 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.

I tried 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.

I tried 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 and 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 I noticed tends to dispense a lot of product. I’ve tested this 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.

I tried 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, this one is soo light, smooth and hydrating. It’s on the emollient side for a milk cleaner in my experience. I love that it’s got white water lily extract and safflower oil and immediately melts into skin. I don’t find the cleansing power to be very strong though and prefer it as a second cleanse.
