OSEA Malibu Skin Care Review



Osea Malibu is a vegan skin care brand that formulates their products with seaweed extracts as the key ingredients. The inspiration to use seaweed in their formulations comes from the family’s great grandmother Elsa Reuschle, who healed several torn tendons in her leg by swimming in the Long Island Sound. She attributed her recovery to the full spectrum of minerals and trace elements present in the saltwater and the abundance of seaweed found in the sea.

Elsa’s granddaughter, Jenefer Palmer, founded Osea Malibu in 1996 after more than a decade of formulating the products. Today, the family is still involved in every aspect of the company, continuing to share their deep love for the sea with the world. In this review, we’ll discuss the brand’s best selling products, key ingredients, Osea Malibu reviews from real customers, and more.

What’s Inside OSEA Malibu Skin Care?

As we’ve already mentioned, the OSEA Malibu brand was built on the concept of using nutrient-dense seaweed extracts to heal the skin. Thus, the brand uses quite a few different seaweed extracts to formulate the OSEA Malibu skin care products. Let’s take a closer look at how these seaweed extracts may benefit your skin. 

Undaria Pinnatifida
First up is Undaria Pinnatifida, a brown marine algae rich in minerals like sodium, iron, potassium, iodine, and calcium, as well as vitamins B1, B2, B3, B6 and B12.

According to a 2013 publication in the journal Marine Drugs, brown algae contains phlorotannins which absorb certain UV light to act as an antioxidant and therefore protect collagen.

Another component of brown algae called fucoidan can help with wound healing by protecting elastic fibers in the skin from breaking down over time. Fucoidan also improves skin hydration and promotes a youthful, plump appearance. 

You can find this ingredient in the OSEA Malibu Undaria Algae Body Oil, Vitamin Sea Serum, and Sea Minerals Mist. 

One of our favorite antioxidant-rich moisturizers is Carrot & Stick The Moisturizer

Gigartina Skottsbergii
The next algae extract you’ll find in several Osea Malibu skin care products is Gigartina Skottsbergii, a red marine algae with hydrophilic (water-binding) properties that make it an excellent moisturizing agent.

It helps protect skin against external aggressors such as extreme dry climates, wind, and air pollution. Gigartina is rich in iodine and bromine, as well as sulfated polysaccharides, which are known to hydrate and reduce the appearance of fine lines and wrinkles.

This ingredient can be found in the OSEA Malibu Advanced Protection Cream, Gigartina Therapy Bath, and Ocean Cleansing Milk. 

Macrocystis Pyrifera
Another key ingredient in Osea Malibu skin care products is Macrocystis Pyrifera, the largest of all marine algae. Like all seaweed, Macrocystis is a rich source of iodine, as well as several other vitamins and minerals. 

When applied to the skin, Macrocystis helps reduce the appearance of blemishes and surface redness, while improving skin texture and tone. It has a gelatinous quality which helps to reduce the appearance of fine lines and wrinkles while giving the skin a healthy glow. 

You can find this ingredient in the OSEA Malibu Blemish Balm, White Algae Mask, and Hyaluronic Sea Serum.

So besides these three seaweed extracts, what other ingredients can you expect to find in OSEA Malibu skin care products? We noticed that the brand includes skincare staples, like vitamin C and peptides. Both of these ingredients should be part of your skincare routine. Here’s why:

The Top 5 Osea Malibu Skin Care Products

Undaria Algae Body Oil
This top selling Osea Malibu oil is derived from organic Undaria Algae that has been soaked in a blend of seed oils – acai, babassu, and passion fruit – for 6 months to naturally distill the vitamins and minerals into their purest, most potent forms. For example, this brown marine algae is rich in iodine, iron, potassium, calcium and vitamins B1, B2, B3, B6 and B12. The Undaria Algae Body Oil is said to firm the skin in order to eliminate the look of sagging skin and reduce the appearance of stretch marks.

Hyaluronic Sea Serum
The Osea Hyaluronic Sea Serum is a fragrance-free hydration serum for all skin types. It is said to visibly improve signs of aging, increase facial volume, and encourage brighter, firmer skin. The key ingredients you’ll find in this serum include three organic seaweeds and multiple molecular weights of hyaluronic acid.

BEST ALTERNATIVES: Carrot & Stick The Repair Serum

Atmosphere Protection Cream
The Osea Atmosphere Protection Cream is a lightweight facial moisturizer that provides barrier protection against extreme climates, wind, and air pollution. In addition to containing algae extract as the key ingredient, the formula includes several natural emollients, including shea butter, macadamia seed oil, and avocado oil. This cream is said to leave a silky finish on the skin, making it an ideal primer for makeup.

Blemish Balm
If you’re struggling with acne-prone skin, you may want to consider the Osea Blemish Balm. Key ingredients in this formula include three varieties of organic seaweed combined with tea tree oil, juniper oil, and thyme oil. The Blemish Balm is said to minimize shine, calm blemishes, and soothe surface redness. It is also said to be ideal for sensitive skin or those who cannot tolerate heavy moisturizers.

Advanced Protection Cream
The Osea Advanced Protection Cream is an anti-aging facial moisturizer that is said to plump fine lines, blur wrinkles, and reduce the appearance of dark spots. One of the key anti-aging ingredients in this formula is dipalmitoyl hydroxyproline, which consists of two palmitic acids attached to hydroxyproline, an amino acid. It is absorbed through the skin where it promotes collagen synthesis and plays a role in the three-dimensional folding of collagen fibers. This may result in stronger, firmer skin that is less susceptible to wrinkle formation. The Osea Advanced Protection Cream is recommended for drier skins and climates.

BEST ALTERNATIVES: Carrot & Stick The Defence Serum.

Osea Malibu Reviews

Osea Malibu reviews on the brand’s website are very positive, with most products receiving four and five star ratings. The product with the most reviews is the Osea Atmosphere Protection Cream, which has almost 400 five-star reviews.

The positive Osea Malibu reviews for the Atmosphere Protection Cream comment that this cream effectively hydrates the skin without being greasy or heavy. Many reviews mention that it is a great option for those with oily and/or acne prone skin. One Osea Malibu review says, “I’ve been using this lotion every morning for a year and I love it! I use it at the end of my skin care routine (all Osea products) and it’s the perfect daytime moisturizer! Leaves my oily skin feeling soft and hydrated without being too heavy and soaks into my skin very quickly so I can immediately follow up with my non-toxic makeup routine. My skin feels great throughout the day and I end the night without any excess oil production. A little goes a long way too as you only need 1.5 pumps to cover your whole face and neck, so one bottle lasts me nearly 6 months.”

What’s impressive about the Osea Atmosphere Protection Cream is that there is currently just one 1-star review for this product. And this negative review doesn’t even have to do with the product itself, but rather the brand’s customer service. The review says, “While I adore the Atmosphere Protection Cream, it arrived to me smashed. I sent an email immediately and it has been a week with no response. I am disappointed at the level of customer service and truly expected more.”

Osea Hyaluronic Sea Serum Review

Osea Hyaluronic Sea Serum is a lightweight, non-greasy moisture boosting serum that is said to smooth wrinkles and fine lines, as well as replenish dry, thirsty skin. This serum features a synergy of three molecular weights of hyaluronic acid, which is an exceptional ingredient for adding hydration to the skin. Hyaluronic acid draws in moisture from the environment and can hold up to 1,000 times its weight in water. It also helps to plump skin, reduce signs of aging, and give the skin a youthful, dewy glow.

Osea Hyaluronic Sea Serum also contains three organic seaweeds: Gigartina Skottsbergii extract, Macrocystis Pyrifera extract, and Undaria Pinnatifida extract. Gigartina Skottsbergii is a red algae that is rich in polysaccharides, vitamins, and minerals that deeply hydrate skin and promote the appearance of youthful volume and firmness. It also helps protect skin from external aggressors such as wind, dry climates, and air pollution. Macrocystis Pyrifera is a brown algae abundant in vitamins, minerals, antioxidants, and essential fatty acids. It helps minimize the appearance of surface impurities and irritation, as well as visibly reduce uneven skin texture. Undaria Pinnatifida is a brown marine algae rich in iodine, iron, potassium, calcium and vitamins B1, B2, B3, B6 and B12. It also contains fucoidan, a particularly hydrating compound that promotes a youthful, plump appearance. Undaria Pinnatifida extract helps reduce the appearance of fine lines and wrinkles while also minimizing the appearance of surface redness.


Osea Atmosphere Protection Cream Review

Osea Atmosphere Protection Cream is a lightweight face moisturizer that is said to help provide barrier protection against visible damage caused by environmental stressors, such as dry climates, wind, and air pollution. One of the key ingredients in this cream is algae extract, which nourishes the skin with vitamins and minerals and also hydrates by binding water to the skin. This cream also contains a high concentration of Macadamia ternifolia (macadamia) seed oil, a lightweight oil that is absorbed quickly by the skin without feeling greasy. Macadamia oil is rich in linoleic acid, an essential fatty acid that helps to restore the skin’s barrier function.

There are several more barrier-replenishing ingredients in the Osea Atmosphere Protection Cream, including jojoba oil, avocado oil, and vitamin E. A strong, intact skin barrier helps to prevent water loss and keeps harmful environmental irritants out of the skin. Vitamin E is also a potent antioxidant that protects the skin against free radicals, the unstable molecules that contribute to the formation of premature wrinkles and fine lines on the skin. Lastly, Osea Atmosphere Protection Cream includes several ingredients that contain volatile fragrance components, including lavender oil, geranium, and grapefruit peel oil. Although these are natural essential oils, they still have the potential to aggravate the skin.


Osea Ocean Cleanser Review

Osea Ocean Cleanser is a mineral-rich organic seaweed gel cleanser that is said to effectively remove excess oil and surface impurities from skin while maintaining a hydrated, healthy looking complexion. There are two natural cleansing agents in this product: decyl glucoside and sodium lauroyl oat amino acids. Decyl glucoside can be derived from either corn or coconut, and sodium lauroyl oat amino acids is a salt created by condensing the chloride form of lauric acid (a fatty acid) with amino acids derived from oat protein. Both are considered to be very gentle and are not associated with causing skin dryness or irritation. Osea Ocean Cleanser also features algae extract, which is known to bind water to the skin and improve hydration.

Another key ingredient in Osea Ocean Cleanser is vegan lactic acid (derived from beets). Lactic acid is a type of alpha hydroxy acid (AHA) that is particularly beneficial for those with sensitive skin because it provides gentler exfoliation than other AHAs, such as glycolic acid. It works by breaking down keratin, a protein that acts as a glue to keep dead skin cells together. By dissolving keratin, lactic acid helps to exfoliate the top layer of dead skin cells, leaving skin looking brighter with a more even tone. Lastly, Osea Ocean Cleanser includes many ingredients that contain volatile fragrance components, such as lime oil, orange oil, juniper oil, jasmine oil, and more. Although these are natural essential oils, they still have the potential to aggravate the skin.
