"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

Special treats

"Thank you for reaching out and providing the opportunity to share my feedback on the Marin Lip Duo. I am genuinely impressed and delighted with this product. The combination of items within the duo offers a truly luxurious and pampering experience, making my lip care routine feel like a special treat. Beyond the pleasant application, my lips now feel remarkably hydrated and visibly repaired, contributing significantly to their overall health and appearance. Thank you for creating such an excellent product."

— Alicia E. (5/5)

Love Strawberry Rhubarb!!

"The strawberry rhubarb lip balm is delightful! I’ve gone through 10 tubes already and can’t get enough of the fruity vanilla goodness! So hydrating, glossy, and deliciously scented. It’s completely replaced all my other lip balms, it’s that good. Thank you for making such an amazing product and please consider upgrading strawberry rhubarb from limited edition to core flavor!"

— Erin (5/5)

"I LOVE the strawberry rhubarb scent, but this blueberry French toast one was way too sweet for my liking. If anything, I think the scent was just overpowered by too much syrup. Still LOVE how moisturizing this product is, and I will definitely buy in a different scent, but this french toast one was a no for me."

— Cayley (2/5)

The best

"I have tried many lip balms but the marin lip balms have become my favorite. The mint one is my fave but the other scents are great too. They are the perfect consistency, super hydrating and dont feel tacky on the lips. The scents are so unique and delicious you could almost eat it. Obsessed. Purchased all the scents."

— Brenda C. (5/5)

MY GOODNESS these are sooo good!

"I absolutely LOVE these lip treatments! They are thick, nourishing, and scrumptious. The Campfire S’mores and Strawberry Rhubarb are my all-time favorites, and Mint is up there, too. The mint is nice post-meal because it’s as refreshing as if I popped a mint or piece of gum in my mouth. I’ve tried and use several of the well-known lip products in the market, and I always keep coming back to Marin. Such a great product that I love telling my friends about and letting them take a sniff of the yummy scents!"

— Kendall (5/5)

The only thing that consistently WORKS

"I am obsessed with this lip treatment!! I received it as a Christmas gift last year and have ordered it myself since because it works so much better than anything I’ve ever tried to keep my lips hydrated. I’ve always had a problem with dry lips that start to crack and peel and it tends to go downhill fast. This product prevents them from drying out and my lips have never been so consistently healthy! Absolutely love it. Will recommend every time."

— Izzy T. (5/5)

LOVE my Marin lip balms!

"These lip balms are amazing. I bought 4 of the 5 flavors: Strawberry Rhubarb, Mint, Unscented, and Blueberry French Toast. From the minute I applied the lip balm, I was hooked. It goes on so smoothly and really hydrates my lips. The scented ones smell divine ✨️ and the unscented one is perfect for when I just want something light. The Strawberry Rhubarb has a red tint that looks amazing on me. Im obsessed and cant wait for new flavors to come out!"

— Amanda (5/5)

"Love the lupgliss however on this recent tube i ordered there is a defect on the applicator and its uncomfortable to apply. I still really live the product just didnt enjoy it as much this time."

— Genevieve (2/5)

Game changer!

"I have struggled with extremely dry lips forever and even my favorite lip products have always left me looking for something better. This may be it! I’ve been using it less than a week — a few times a day (along with other lippies) and a generous application before sleep — and have noticed a real improvement. I used to wake up with lips like a cobblestone road no matter what I used. Now I’m waking up with soft, smooth lips. I really like the flavor (strawberry rhubarb). I’m am allergic to some ingredient in most flavored lip balms, but did fine with this. It is quite sticky, but that’s not really a deal breaker for me, especially if it works so well. It is also pretty tingly like a plumping gloss (it doesn’t claim to be plumping and doesn’t seem to plump my lips, but those things never seem to work on me). It’s not bad and worth it if you struggle with dry, chapped lips. I’m going to buy more as soon as I’m done with this review!"

— Sarah T. (5/5)

MOLDY?!

"I purchased the mint and unscented in December 2025. I’ve been using the mint with no issues and opened the unscented 2 weeks ago. To my surprise, it appears to be MOLDY inside the applicator! Disgusting and unfortunately going in the trash after only a handful of uses. This product was opened from its original packaging for only 2 weeks and well within the 12 month expiration. Disappointing."

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!
