Description

Marine Serum is the product that launched Sabbatical Beauty into existence. It is supercharged with deep ocean antioxidants that help to heal irritated, red skin, acne-prone skin. It smooths away fine lines and makes your skin just wake up with an unbeatable glow.

Ingredient Deep Dive:

🌊 Sea Kelp Bioferment: Fermented Sea Kelp is so deeply healing to skin that it has launched many a marine-focused skincare brand. This jelly-like, skin microbiome-happy-making substance forms the majority of Marine Serum and gives it is bouncy texture.

🌊 Red Algae, Black Algae, Giant Sea Kelp, Hawaiian Algae: Practically every seaweed in existence is in this serum to help with skin renewal. These seaweeds are often used in cosmeceutical products to increase collagen production and protect collagen and elastin, even skin tone and moisturize. Alginic acid in these sea plant extracts has a superfood effect (with antiviral and antioxidant activity), improves skin hydration, enhances wound healing and increases skin elasticity--thereby having an anti-aging effect. Red algae extract contains a compound that helps to diminish the appearance of wrinkles and age spots, and improve skin elasticity and texture.

🌊 Fermented Wakame: Wakame is a Japanese seaweed that you may often find in your miso soup that is super rich in sea vitamins and minerals and high in Vitamin C for cell renewal. Fermentation helps break down cellular walls, making nutrients more bioavailable to your skin.

🌊 Tahitian Sea Water: contains beneficial sea salts which improve skin (improve skin barrier and skin hydration, reduces inflammation, reduces skin wrinkling and roughness)

🌊 Marine Collagen: helps improve skin moisture levels, synthesize collagen and rejuvenate your skin.

Everyone needs a touch of Sea Serum

I can’t wait to repurchase this product! Love how soft and smooth it has made my skin and helped reduce redness and chronic inflammation I have experienced over the past two years, with no help from dermatologists. Sabbatical products are the only skincare products I use. I followed their page for over two years and finally said “what have I got to lose by trying ANOTHER skincare line” and turns out it was the best decision for my skin care issues. Thank you!!!!

Hi Lisa,
Thank you for taking the time to write us a review. We're so happy to hear that Marine Serum is such a staple in your routine. We're glad you're here with the Sabbatical Beauty family! - SB Team

Helps W Redness, Better W Asian Powerhouse

I bought this product as recommended to counter my redness near my chin and nose area. While it didn’t complete remove the redness, it definitely toned it down. I found that the constitution of this product works better if you apply Asian Powerhouse first because Marine is a bit stronger. It doesn’t work as well for me on its own without the APH. I love the way the product looks (the color and texture) makes me feel like a mermaid when I put it on my skin :)

Hi Sonjachardé, Thank you for the review on the Marine Serum, we appreciate your feedback! - SB Team

Absorbs well

I got a travel-size version of this along with the Asian Powerhouse serum as one of my earliest purchases of this and somehow ended up using this up more quickly than the APH. (That being said, a little still goes a long way.) I primarily have dry skin so this seems to do a pretty good job of hydrating even though it's not actually a moisturizer. I like how it seems to calm down my skin when it's more inflamed too!

I love Marine serum. It helps my skin feel more balanced and nourished, controlling excess oil and also brightening. I also love how it makes me feel like a mer-being and brings the beautiful sea close. Thank you for making such gorgeous products SB! <3

Even tone and less redness

I have always had red and inflamed looking skin. I’ve tried so many products in the past, but nothing has ever been as soothing and effective as the marine serum. This was the first product I purchased and after seeing how much it evened out my skin tone and left my skin moisturized and glowing - I will be a lifelong customer!

it thick and gooey but it absorbs so well into my skin

I restock my marine once I finished my sample size from the revive set. Not sure the exact things that Marine does, but I noticed my acne scars got much lighter and my overall hormonal cystic acne skin is much better after a month of daily usage. I feel that the APH and marine (the only serums in the set) must have played an important part in the improvement of my skin. It gets absorbed quickly as well..

Love at First Squeeze

In addition to all the marine nutrients you never knew your skin craved, this serum seems to include... for lack of a more informed guess, sorcery? Using it leaves my skin feeling bouncy and plump, and looking more radiant than usual. You'll thank yourself for giving it a try! Plus, a little bit goes a l-o-n-g way.

It’s all about the FEELS

This serum may be my favorite SB product of all. There’s just something about MARINE that not only makes my skin look better, but immediately after application my skin FEELS better — smoother, hydrated, softer. That’s why MARINE will always have a place in my routine.

Part of my daily routine

Along with Asian Powerhouse and Dorian Gray Oil, it’s done wonders for my skin!

This is bang for the bucks!

If I have to pick my best find treasure in Sabbatical Beauty- Marine serum is topping the list for affordability and delivery. It gives me the needed moisture- yet not oily in anyway! If you watch SB webminar of which serum this compares to, you be thrilled you are here! Looking at a really good serum at affordable pricing that I won’t feel guilty to put a few drops more in my face. After applying, let it sink in and then go on routine!

A must-have

I have replaced my core serum by Marine Serum. It soaks effortlessly to my skin

Seaweed that's not meant for cooking!

I was initially a bit skeptical with the ingredients. A lot of the other SB products had key ingredients that I had heard of through Kbeauty already but seaweed? I had only used seaweed for cooking and had never heard or used it as a product! Marine Serum was also the 3rd SB product I had ever used (besides Vacuum Cleansing Oil and Asian Powerhouse). It was also the product that finally convinced me to go full-time SB - only a very small amount (2 to 3 droplets) a day and my skin felt moisturized and less inflamed. It's a great base for days when I have to quickly run out the door in the morning and it feels light but protective. It's definitely a part of my morning SB core armor (APH, Marine, Piper's Peat).

Love this product!!

I absolutely love this product!! I have just been introduced to SB, and I am thrilled with what I’ve tried. Paired with Asian Powerhouse this product brightens and evens my skin.

Big fan!

This is my second bottle and I am loving this serum! It's not too drying and easy to absorb into my skin. I feel fresh after each application and feels like my skin is ready for any products in my routine!

Seems good!

I use this with the Asian Powerhouse serum and together they seem to help skin issues clear up faster than usual. I find this easier to apply than the more liquidy Asian Powerhouse serum.

Soothing

When I use this at night, I feel like my skin looks and feels healthier in the morning. Im using this in conjunction with hydra and Asian powerhouse, and I love them all!

V

My go to!

While I can't do aph or hydra every day (I have super sensitive skin), this one is amazing. It immediately hydrates, and I like its consistency. I just ordered the full size, because it is a set part of my routine now.

G
Georgia Bianchi (Gainesville, US)
The best, especially when paired with Asian Powerhouse

I first got a sample in the Revive set in July 2016 and haven't been without this serum since. Especially when paired with APH, this serum is so soothing. I finally ponied up for the full size, and I am never going back.

Better Than That $300 Cream!

Marine Serum has become a daily necessity in my skincare routine. The ingredients list is so impressive and clean, it's like I dip my face in the ocean everyday! Using this serum with your other skincare instantly transforms your treatments into that insanely overpriced skincare line that boasts of luxury ingredients of the sea in their "Miracle Broth" (a secret cocktail of stuff they have yet to disclose). The truth is, there are more filler ingredients in their $300 jar of cream than Marine Serum's entire ingredients list. Since using Marine, my skin has a lit-from-within radiance and natural dewy glow. All redness has disappeared, even around my nose! My pores are also visibly smaller. I don't wear foundation anymore, but on rare occasions I'll wear a tinted moisturizer or bb cream. If there is 1 beauty product in this whole world that is worth your hard earned money, it's Marine Serum.

If I am layering Marine Serum and Asian Powerhouse, which one should go on first?

You should layer APH before Marine. XO, Team SB

WHY I MADE THIS

In 2015, I was on sabbatical from my job as an English professor, with red, irritated skin that nothing on the shelf could fix.

Everything I tried was too harsh or too diluted to do anything. So I started formulating myself, and this was the first thing I made that actually worked. More than 10 years later, I still make it by hand in South Philadelphia.
