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.

Tamanu Oil: Soothes irritation and calms redness without greasiness.
Niacinamide: Helps clear spots, fades discoloration, and brightens skin.
Ceramides: Essential to skin health—helps replenish fatty building blocks of the skin barrier.

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.


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.

SKINSTRUCTIONS

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.

“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.”

    A Lifesaver for My Broken Moisture Barrier!

    Skin type: combination, acne-prone, currently suffering from massive breakout, PIE, redness, and sensitivity from overexfoliation using 2% BHA.

    Oh my goodness, I cannot thank my friend enough for putting me on this. I was a little skeptical at first since it dried down so cleanly. I thought it wouldn't be moisturizing enough, since everything else that's been helping my skin recover thus far have been fairly greasy (which I dislike but accepted as a necessary evil in recovering my moisture barrier).

    KB Great Barrier Relief, overnight, made absolutely radical changes to my face complexion! I have lots of closed comedones that I accepted would eventually erupt into painful acne - a good third of them are gone. Reduced redness, tightness, and stinging. The acne I already have look so much calmer and ready to resolve themselves. And on top of everything, this formula is hardly greasy at all!

    Though it's not on the cheapest side of skincare, it's still at such a good price point for what it could do for you. I'd give it ten stars if I could!

    So Soothing

    This always soothes my skin and makes it feel bouncy. Ive also come to love the "earthy" scent that this has.

    Love it!

    I will definitely keep repurchasing this product! I love that it is more than just 1oz (which is common for a lot of serums), and it actually works! This helps my scars heal more quickly, helps with dryness, makes my skin feel smoother, and more. I highly recommend!

    MY HOLY GRAIL

    This stuff is magic. I have repurchased it about 4 times. My skin is at its absolute best when I use this product. I’m less dry, less red, and have less breakouts. It helps calm my dermatitis and clear my skin. If I stop using it I notice a huge difference.
