Developed by Bioengineers who understand

"My eczema was really bad not only around my eyes and face, but also on and around my lips, so I knew from experience that there weren’t products that addressed this painful problem. There was a serious need for lip products designed to be safe and effective for this delicate area that everyone can use - we knew we had to introduce a lip treatment"

Reviews

The one and only

"The first lippie I ever purchased from Marin and my undisputed fav, the blueberry french toast, for all the reasons: the absolutely unique blueberry maple blend, the surprising shine on the lips but most of all its serious hydration game. This lippie was all I needed for my honeymoon road trip in Iceland, where it kept my lips super smooth and glossy in all temps and situations. It just smells like fall, having a cozy brunch before going to look at the leaves changing, and is a treat on the lips."

— Alyssa (5/5)

Unexpected and Delightful Texture

"The lip treatment is sort of like a cloud-whipped Chapstick…kind of light and airy, but lasts all night and does fairly well in the day, too! Super strong cranberry tint and fairly strong scent upon application, but not after. I kept getting recommended this to treat lip issues like dry lips but I never had any such issues until I got an allergic reaction to Naturium’s lip balm, and this Marin treatment helped soothe my lips the next day until they returned to normal!"

— nainika s. (5/5)

I Smell Donuts!

"I think Cider Donuts Lip Treatment might be my favorite scent. It used to be Blueberry French Toast (which I still love BTW) but Cider Donuts is WOW! Same great lip treatment but now with a new yummy scent!"

— Leslie E. (5/5)

Forever repurchase!

"I love love love the Marin lippies! They have saved my lips from constantly cracking and peeling due to hEDS and the flavors are so lovely. I've tried the Blueberry French Toast, Campfire S'mores, and Strawberry Rhubarb so far and I'm really looking forward to trying the mint and cranberry (but SR is my absolute favorite, it smells so good!!)"

— Katie (5/5)

Cider donut 😕

"Hi Guys I have been a fan since day one and have every flavor but this one, it just misses the mark for me, to the point I can’t use it it’s just not good, Idon’t get cider don’t get salt don’t get donut…I bought 2 one as a gift and I don’t think I can gift it. I’m super disappointed knowing you worked on this for 2 years I’m so sorry guys I love the product soooo much but this flavor just no for me sorry again 🫤"

— Kristi D. (2/5)

Love it!

"I've never been disappointed in a Marin product! The lippies all smell like their advertised scent. I love that I don't have to apply it as often as it works well and lasts longer than any lip balm I've used before. Cider donut has me feeling like autumn and gingerbread has all the warmth of a cozy winter day."

— Tara S. (5/5)

The best lip treatment EVER!

"I have tried SO many lip treatments and Marin is by far the best. The smell, the feel, the whole thing. Marin’s scents are so incredibly realistic which is a huge plus. Needless to say i’m hooked and I have almost all of them! Cider Donut is by far my new fav! It smells like going to the apple orchard in Maine and eating a delicious cider donut :) 11/10 recommend"

— Bradine W. (5/5)

"Ever since I tried Marin there’s no other lip brand that I have found superior and as a Mainer I’d prefer to buy these over anything else! The flavors are amazing, very hydrating and it lasts a long time before your next application. Very happy with my Marin as always!"

— Kassidy (5/5)

This stuff is like gold in a tube

"My holy grail. My one and only. I love Marin lip balms with every ounce of my heart. I've been a lip balm fanatic since I was like 8. I've been on a constant search for a balm that not only actually HEALS my lips but also has a wonderful scent/flavor that makes me want to put it on all the time. In a world of strawberries and vanilla, Marin is out here making gourmet flavors that are to die for. I tell everyone about Marin. I cannot speak highly enough of this product. 1million/10 you need this lip balm!!!"

— Faryne M. (5/5)

My New Fav!!

"The packaging is a 10 out of 10, the donut paper bag was a genius idea! The scent isn't too overpowering, the formula is amazing as always, and the apple cider donut gives the perfect fall feelings! Will be buying again!🍎🍩❤️"

— Reese W. (5/5)

Q&A

Frequently Asked Questions

  • Safety and non-irritation is really important to us!


    We had Dermatologists clinically test this to make sure it's a non-irritating
    formula. They performed what's called a repeat insult patch test study (RIPT study), where 50 participants apply the product for a period of 6 weeks, tested
    each week for signs irritation. Our participants experienced no irritation throughout the entire study!

    Moreover, we formulated this product to be irritant-free, fragrance-free, paraben-free, and comply with the National
    Eczema Association's list of unapproved ingredients!

  • We discovered a new ingredient: Marine Glycoproteins!

    As Bioengineers, we worked with lobster scientists to discover a glycoprotein that allows lobsters to regenerate limbs - in the same way they do this, they help repair the skin barrier!

    A natural, upcycled byproduct of lobster processing, this superpowered regenerative protein helps:

    • Hydrate dry skin

    • Soothe upset skin

    • Repair, soften and renew damaged, weathered and aged skin.

  • Use in the morning, evening, and as-needed throughout the day.

    Suitable for use on your face, hands, and body.

    To apply, rub a dime-sized amount into your skin in the morning, throughout the day as-needed to spot-treat, and at night after exfoliating or simply before bed. For extra-irritated skin patches, use the Soothing Hydration Cream to keep it moist as possible throughout the day.

    When applying to areas of your face, as a relatively thick, rich cream, we recommend starting with a pea-sized drop and increasing the amount applied if necessary.

  • We actually have a BUNCH of people using the cream to help soothe skin prone to
    eczema or psoriasis! This is actually why we founded Marin and created the
    product - after the glycoproteins helped *finally* soothe our own eczema, we
    felt compelled to bring this new, natural solution to others like us!

    Overall, glycoproteins do a great job hydrating and repairing dry, damaged skin, while also smoothing and softening rough skin out - a combination of concerns that is
    common among many people with psoriasis, dermatitis and eczema.

    We think reviews for concerns like psoriasis speak for themselves - you can actually search reviews at the bottom of our Soothing Hydration Cream page, here!

  • We actually have a lot of parents and grandparents using the cream for their little ones!

    We've noticed that a lot of people prefer a more natural alternative to steroid creams, which can sometimes cause more damage than good. To be extra sure that Marin is gentle
    enough for their skin, we recommend applying a little dime-sized amount of
    product on before use, observing for any irritation, and continuing use once
    you've made sure their skin likes Marin!
