6 Things You Need To Know About COSRX Snail Mucin

COSRX Snail Mucin Essence ReviewedThe CosRX Snail Mucin serum is getting popular right now.

And that's probably why you have been searching about it.

The big question is:

Should you get it? And if you've ordered it, how can I get results from it?

Well, that's exactly what you're going to learn in this guide.

Let's begin:


What does COSRX Snail Mucin Essence do?

This hydrating serum is a lightweight, concentrated essence with an active ingredient of 96% snail mucin, a naturally occurring substance found in snails.

Snail mucin is known for its moisturizing, anti-inflammatory, and regenerative properties, popularized by K-beauty trends.

While the mucin extract in this skin toner is the star ingredient, we’ll take a deeper look at COSRX Snail Mucin Essence 96, especially its ingredients (what we love and don't love), how to best use it, before and after reviews, and any side effects or pros and cons.

Ingredients – Good & Bad

The primary ingredient in COSRX Snail Mucin Essence 96 is the 96% snail secretion filtrate. This is an extract of the mucus that snails secrete and is a rich source of hyaluronic acid, glycoproteins, antioxidants, and other compounds that have beneficial skin-care properties.

In addition to this snail secretion filtrate, the product contains other beneficial ingredients such as sodium hyaluronate, allantoin, panthenol, and glycerin.

sodium hyaluronate skincare

All these ingredients work together to help repair and protect damaged skin, while also providing intense hydration.

COSRX claims this product is Paraben-free, Sulfates-free & Phthalates-FREE which we love.

What We Like

The concentration and effectiveness of the snail mucin (96%) and how its obtained in an environmentally friendly way without damage to the snails.


What We Dislike

Some of the synthetic ingredients used in the serum give us concern. Our research shows that skin exposure to phenoxyethanol (one of the preservative ingredients) has been linked to allergic reactions ranging from eczema and hives.

Plus, some of the other ingredients are synthetic polymers, such as sodium polyacrylate and carbomer, which come from petroleum and is considered a moderate hazard ingredient by the EWG Cosmetics Database.

These are essentially plastics in cosmetics and we are not a fan.

Yes, we are reminded regularly that skin care products only use phenoxyethanol in small amounts that are “not harmful” to skin.

But if you use such products multiple times a day, every day, the cumulative effect may be a concern (especially if you have sensitive skin). That's why we prefer organic or botanical based face serums that use less or no synthetic ingredients.


How to Use

To use it as a moisturizer, apply a few drops to your face and neck and gently massage it into the skin.

For example, here are snippets of some candid reviews from verified buyers:

" ...I do wash with a cleansing cream so my face is fresh before I use it, and I can't say I notice big changes but I can say that my skin isn't again at a face rate, it lasts quite a while and leaves skin dewy... "

 "...Every time I used this product, after a few hours I have to wash my face because I couldn’t handle how it made my skin feel... "

"...My skin is clear and the texture is so much more improved. It also helps keep my skin hydrated all day!..."

"...I used it on only one side of my face while I used a different one on the other side to see which one worked more. Unfortunately, this stuff gave me AWFUL acne. My other cheek is completely clear. It also made my lips tingly if it got near. Apparently, if you’re allergic to dust mites, this stuff can cause an allergic reaction or skin irritation..."

 "...I won't say it has stopped the aging process but I can honestly say my face/neck area feels so much better: softer, cleaner and healthier... "  

 " ... I have super sensitive eczema prone skin with a long list of allergies - pollen, dust mites, sweat, chlorine (to name a few). ... People with DUST MITE ALLERGIES have ALSO been found to have SNAIL MUCIN ALLERGIES, so definitely patch test if you have a dust mite allergy!..."

 " ...I have combination-dry as well as acne-prone skin and I have found that this helps me with repairing and maintaining my skin barrier as well as helping with my overall skin texture... "
