What are skin serums and do you need them?

While some things get better with age, our skin is, sadly, not one of them. Plenty of women and men aim to lessen the imperfections brought about by aging, with various skincare products, with serums being the latest rage.

A skin serum is usually a water or oil-based liquid that most often comes in little bottles equipped with droppers. A serum is not a moisturizer but rather a substance filled with a highly concentrated dose of ingredients that should be able to address most common skin complaints, such as wrinkles, dullness, skin discoloration, and so on. Because a serum delivers a highly concentrated dose of anti-aging ingredients deep into the skin, they’re known to be quite efficient at their task.

Thus, if you’re looking for something a bit more effective than a moisturizer or sunscreen to add to your routine, think serums.

Learn how it works

Are there side effects of using skin serums?

Generally speaking, a serum that is compatible with your skin won’t leave you experiencing any unwanted side effects. However, not every serum might work for your skin, and using some might make your skin tingle at first until it gets used to the concentrated formula.

That said, as with any beauty product, you should always opt for a patch test at first to see how your skin reacts to the active agent. If the patch you’ve tested on your new serum doesn’t become itchy, red, or dry after 24 hours of trying it on, you are good to go.


How do you choose a skin serum?

First off, know what you want to target with your serum—is it wrinkles, spots, dullness, or maybe something entirely different? Once you know the problem, you’ll know the serums you’ll need to look into. Some serums are a mixture of active ingredients, and others carry just one, but both formulations work as well as the other, and it’s more a matter of preference.

For aging combinations, you might want to look into vitamin C, vitamin E, and ferulic acid combinations. For wrinkles, try resveratrol, tea polyphenols, retinol, and niacinamide. For blotchiness, serums with glycolic acid work well. And if dry skin is your concern, look for something that contains ceramides, for they’re excellent in locking moisture in your skin.

Now that we know the basics of serums, let’s go back to our star of the show here, the COSRX Advanced Snail Mucin Serum, and talk a bit about it.

What does COSRX Advanced Snail Mucin Serum do?

The COSRX Advanced Snail Mucin serum is formulated to target damaged skin, improve its elasticity, and maintain hydration levels throughout the day. The serum contains skin-friendly essential ingredients to nourish, repair, and revitalize the skin.

Sounds too good to be true? Well then, let’s try to figure out why so many people like it and what the secret behind its formulation is.


COSRX Advanced Snail Mucin Serum formulation

As with any good nourishing and repairing serum, this one includes allantoin and panthenol, both of which are well-known and often used ingredients to improve skin condition. Both are highly tolerable by even the most sensitive of skins; however, that isn’t where the magic of this serum hides. It’s the snail secretion filtrate (also known as snail mucin), of which there’s a whopping 96% in this serum, that does the trick.

What’s snail mucin and why is it good for your skin?

Snail mucus, also known as snail secretion or simply mucin, is exactly what it sounds like – the slime that snails produce to protect their bodies. And if that sounds a bit odd, don’t worry, as all the secretions that are used for cosmetics are filtered and clean.

Snail mucin is a natural moisturizing agent brimming with all the things your skin loves! It’s rich in allantoin, glycolic acid, hyaluronic acid, proteins, antioxidants, and peptides, like all the best serums combined in one.

And the list of what it does to your skin is almost endless:

  • Regenerates, repairs, and rejuvenates your skin
  • Reduces hyperpigmentation and dark spots
  • Heals acne and prevents acne breakouts
  • It has incredible anti-aging properties
  • Moisturizes and deeply hydrates your skin
  • Has anti-inflammatory and anti-bacterial properties
  • Provides you antioxidative protection from free radicals

Not to mention that snail secretion is basically hypoallergenic, with skin reactions almost unheard of. This means it’s well-tolerated by any kind of skin, even the most sensitive.


Why the COSRX serum?

Highly concentrated

For one, it uses a high dose of snail mucin in its formula; a whole 96% of it! As for its effectiveness, there have been several scientific researches to prove it, all agreeing that it is, in fact, effective in battling aging. Not only that, but snail mucin is now widely used as a wound healing agent, as a surgical glue, and even to battle gastric ulcers. And since the COSRX serum has 96% snail mucus in its formulation, you can be sure of high potency in addressing skin complaints.

Dermatologist-approved formulation

Besides, the COSRX formulation is recommended by skin care professionals and dermatologists worldwide due to its skin-friendly and highly effective formulation.

Loved by users

And for another, it has been tried and tested by millions of users around the world who didn’t mind sharing their opinions with anyone caring to read them. We’ve gathered a few of these reviews from Sephora so you can make up your own mind after reading them:

10 out of 10, 5 stars. Amazing product. Would recommend!

Amazing product! I was very pleased with this snail 96 mucin. Its texture is as expected, a little stretchy and hard to get used to but is excellent as a humectant. I've tried all sorts of products to help moisturise my skin and this is something I will continue to use. Excellent to use before retinol or vitamin c to keep moisture in. 10/10.
I can understand the hype!

I bought this as I've been looking for a toner/serum that maintained my skin barrier, whilst also adding glow and moisture. Lots of reviews said it would do just this, and whilst it's not drug store cheap, it's still pretty inexpensive for the amount you get. I'm 45, so no youthful radiance to begin with here, sadly, and I was not expecting miracles, but what I did get was a smooth, easy to apply serum, thay sinks into the skin, whilst leaving a slight trace of moisture. It layered beautifully with my other skin products, and while it won't change your life, as some beauty bloggers infer, it will add polish and oomph to your skincare routine.
Worth the hype?

I have been using this alongside their AHA. It's the best combo. The Snail Mucin is so hydrating, absorbs so quickly. It's just fantastic. I never leave reviews, but it's definitely worth a review! If I ever got spots, the scarring/redness of the spots would be visible for so so long, way longer than the actual spot. So it always seemed like I had spots for weeks. But the AHA and this, any spots that I do get (very rare with that combo) are gone so quickly with no scarring or redness. Permanent staple in my skincare!

As you can see, people recommend it for its hydration properties, giving the skin a soft glow and being highly tolerable.

However, we do understand that you might like to keep your options open here, so we found more serums with the same active ingredient–snail mucin–for you to choose from.
