Frequently Asked Questions

Is this safe/non-irritating, especially for sensitive skin?

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!

What makes this different from other creams?

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

• Repairsoften and renew damaged, weathered and aged skin.

Best way to use Marin?

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.

Has this been tested by dermatologists?

Yes! Tested by Dermatologists at a 3rd party lab to make
sure our data is accurate and non-biased!

Are Marin products vegan?

Our products are made
with marine glycoproteins, which are found in lobster. They are sustainably and ethically sourced as natural byproducts of lobster processing, however, they are not vegan!

Does Marin help skin prone to eczema, psoriasis or dermatitis?

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!

Can I use Marin for my kids?

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!
