A creamy, nourishing serum that calms signs of sensitivity caused by a broken skin barrier. A blend of nourishing oils and rebalancing actives restore damaged skin to clear breakouts and soothe irritation. Skin looks clear, feels calm, and probably sounds amazing.

A Calming Hand

Our skin and the environment don’t always get along. Whether it’s because you’re a city dweller or got too pump-happy with the retinol, your skin needs some back up. Great Barrier Relief is there to lend a hand, no bat symbol required. GBR works by repairing damage in the skin barrier—the skin’s invisible shield. It helps repair tears and strengthen the barrier wall to kick environmental aggressors to the curb. It may be green, but it’s got a black belt in kicking ass.

PETA-certified vegan and cruelty-free. Always free of fragrances, essential oils, dyes, and colorants.

The color and texture of Great Barrier Relief may naturally vary slightly from batch to batch. No worries! This is a normal occurrence when using naturally-derived ingredients and it does not impact the efficacy of the formula.

Note: Great Barrier Relief does contain 10% Tamanu Oil, which is derived from Tamanu nuts. Though most people don’t have issues using this ingredient, people with nut allergies could have a potential reaction. If you think your skin will react, we recommend performing a 24-hour patch test on your wrist and neck first and slowly integrating GBR into your routine thereafter. If you do experience an allergic reaction, stop using the product immediately and seek medical attention if needed.

Water, Propanediol, Calophyllum Inophyllum Seed Oil (10%), Dipropylene Glycol, Niacinamide, Carthamus Tinctorius (Safflower) Seed Oil, Cetearyl Olivate, Polysorbate 60, Rosa Canina Fruit Oil, Glyceryl Oleate, Sorbitan Olivate, Sorbitan Oleate, Octyldodecanol, Glycerin, Butylene glycol, Sodium Hyaluronate, Squalane, Serine, Acetyl Glutamine, Glycine, Ceramide NP, Oleic Acid, Sodium PCA, Glycosyl Trehalose, Caprylic/Capric Triglyceride, Glycine Soja (Soybean) Sterols, Saccharide Isomerate, Avena Sativa (Oat) Kernel Flour, Disodium Phosphate, Sodium Phosphate, Tocopheryl Acetate, Coco-Caprylate/Caprate, Lactic Acid, Xanthan gum, Urea, Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer, Hydrogenated Olive Oil Unsaponifiables, Magnesium Chloride, 1,2-Hexanediol, Hydroxyacetophenone, Glyceryl Caprylate, Pentylene Glycol, Caprylyl Glycol, Disodium EDTA

Pair with Oat So Simple Water Cream
When you’re craving: Extra moisture
Why it works: Water-based cream to hydrate, oil-based serum to seal it in.
How to use: Can be mixed together or applied in any order.
Extra tip: Apply moisturizer liberally but apply serum in layers to prevent greasiness.

Step 1: Clean and separate! Before recycling, make sure your bottle is rinsed and free of product. It is important to separate the pump + cap and silicone insert from the bottle. The pump itself needs to be taken apart into its components: plastic pump, plastic straw, and spring.

Step 2: Investigate! The silicone insert, plastic straw, and spring are not recyclable and need to be thrown away. The remaining pump + cap are made from PP [5] which is accepted by some curbside recycling programs. The bottle is made from 100% PCR (post-consumer recycled) PET [1], which is completely recyclable. We recommend checking with your local recycling to see which materials can be recycled in your area.

Step 3: Recycle! If type 1 and type 5 plastics are both recyclable in your area, we recommend leaving the cap on. The labels or glue can be recycled too, so no need to remove those.

Materials Used
Bottle: 100% PCR PET [1]
Pump, cap: PP [5]
Box: FSC paper and soy based inks

The Best Things Come in 3's

GBR is loaded with Tamanu Oil, a breakout-clearing, texture-smoothing, manicure-giving (beta) active that replenishes skin. Paired with Safflower and Rosehip oil, this trio visibly calms redness and nourishes dry skin from the first swipe.

Millennial Parent Vibes

Niacinamide a.k.a. the soccer parent of skincare ingredients is a master multitasker. It helps prevent breakouts and fades the look of dark spots for radiant, even skin. That’s good parenting.

New Look, Same Old Fave

GBR’s glowed up. Our OG tried-and-true serum is now in an airless pump that pushes out every bit of product, so you don’t need to break it open. Don’t do it, bestie... Just trust us.


How to Use Your Serum

Apply 1-2 pumps on clean, dry skin. Use a little extra for dry skin and a little less for oily skin. Gently massage into the skin until fully absorbed. If using as a sensitive spot treatment, use light pats or apply with a q-tip.

Exhibits A Through You


Skin Concern: dark spots, dryness, irritation

Age: 25-34

“Not only does Great Barrier Relief reinforce my skin barrier, at the same time, it also helps fade dark spots. Its hero ingredient is tamanu oil, which gives it this sage green color and its earthy smell. Thanks to me, this is also my mother's favorite skincare product. She's gone through more bottles than I have.”


Skin Concern: redness & inflammation, sensitivity

Age: 25-34

“Great Barrier Relief is one of my daily essentials in my morning and nighttime skin care routine. She's formulated with a lot of emollients, which work to nourish, soothe, and hydrate the skin. Within two weeks of using Great Barrier Relief, I was able to see an immediate big difference in skin barrier health, hydration levels, and overall skin radiance.”


Skin Concern: dryness, redness & inflammation, sensitivity

Age: 25-34

I felt like it really was the comforting and soothing product that I was looking for, that didn't create any irritation or inflammation. It's like a best friend that just never lets you down. It's always there for you and it's reliable.”

“Using Great Barrier Relief, my skin has had significant improvements. My hyperpigmentation has gone away. I noticed that my itchiness has also reduced, especially around my nose area where I tend to get very red and irritated... It just makes your skin feel so dewy and so luscious.”


Skin Concern: dryness, pores, uneven texture

Age: 25-34

“Great Barrier Relief has completely changed my skin... Putting on Great Barrier Relief brings a really cool, soothing rush to my skin. It's drastically reduced my pore size, really helped with redness, and I feel like my scars heal faster than ever before.”

    Truly reinforces moisture

    This is fabulous - I especially like it in the winter, when my skin is parched, or to help my skin tolerate tretinoin or other retinoids.

    I ordered the Great Barrier Relief serum after seeing it recommended on Hyram’s channel. It has been so helpful at soothing and replenishing my dehydrated skin.

    A permanent staple in my skincare

    I had heard about GBR numerous times on the skincare addiction subreddit; I was a bit skeptical bc the members there tend to exaggerate the effects of certain products and have a “one size fits all approach” to skincare. To them, if one of their “holy grail” products doesn’t work for you, you’re doing something wrong. So hearing about this product over and over with the same sentiments being said made me a bit wary. I finally decided to take the plunge when I had a bout of verydry skin. I liked the product upon arrival and I’ve had no issues with it. I think it is great for my skin but I don’t think it is a magical/miracle product that is “the fountain of youth“ the way some people speak of it. Because I don’t think any product like that actually exists and the key to good skin is lifestyle choices, sun protection, and using products that have meaningful ingredients along with genetics. However, if I were to give somebody a list of products they should try out for their regular regimen I would definitely put this one in the top five products to try out.

    Caution: don't unscrew the pump or you'll find out you've been jipped

    Unfortunately I DISOBAYED the label's "caution" and unscrewed the pump lid. I'd have never purchased this product if I knew how much serum I was actually getting for my money. Misleading packaging. The bottle it comes in is completely untouched by the product. The actual amount would probably fill less than 1/4th of the bottle it's disguised in. Absolutely ridiculous. You sold me an empty bottle with a sample of some product.

    Hi Mara!

    Although the silicone insert may look like it is holding less product, it was designed to contain 45 mL (1.52 fl. oz.) of our Great Barrier Relief formula. As the silicone insert is airless, it will shrink as more product is pushed out until there is nothing left.

    We apologize for the less than ideal experience and we are happy to send a replacement. We will follow up via email.
