[REVIEW] 2019 NEW Cosrx Shield Fit Snail Essence Sun SPF50+ PA+++

Cosrx Shield Fit Snail Essence Sun SPF50+ PA+++ was purchased by Cosmeperks.

As mentioned in my previous review of Cosrx Green Comfort Sun Cream, this is the second part to my thoughts on Cosrx’s latest sunscreen duo! This time around, it’s a formula that’s claimed to be geared towards those with drier skin types, or those who prefer their sunscreens with a more moisturizing finish. Now, while I don’t have super dry skin, I do face dehydration issues, so let’s see how it fares with that.


+ COSRX Shield Fit Snail Essence Sun SPF50+/PA+++ is an essence-like, light-weight texture sunscreen that refreshes your skin with snail mucin and rich humectant components, leaving the skin with a petal-like, baby-skin soft finish.

+ Snail Secretion Filtrate a.k.a. Snail Mucin helps to deeply moisturize, nourish, and revitalize your skin while restoring its youthful glow. Your skin will be balanced and optimized to look and feel healthy.

+Ultra Hydrating Components; Lightweight & Watery Texture:

A high percentage of humectant components leave the skin fully moisturized and refreshed. The texture of COSRX Shield Fit Snail Essence Sun is so light and fast-absorbing that it almost feels like a moisturizer. This hydrating sunscreen glides onto the skin effortlessly without leaving any oily/greasy residue or white cast.

+ Compact Size: Designed to be travel-friendly, so you can easily carry COSRX Shield Fit Snail Essence Sun anywhere and layer on sun protection anytime.

Other notable claims:

  • A chemical sunscreen for all skin types, but especially for when your skin feels too dry to put on makeup or when you want to blend in SPF to your foundation.
  • Protects from UVA&UVB, paraben-free, cruelty-free and dermatologist tested.
  • Light-weight texture that you can layer on every 3 hours for perfect UV shield effect.

Cosrx Shield Fit Snail Essence Sun SPF50+ PA+++ Review

Star Ingredients:

Allantoin: A gentle, non-irritating moisturizing ingredient ideal for sensitive skin. Also known as a keratolytic which means it aids in increasing the water content of cells while also helping in the process of desquamation (ie. to stimulate cell proliferation, encouraging new tissue growth) of the outer layers of the skin.

Panthenol: Also known as pro-vitamin B5. Used primarily as a humectant as it has the ability to attract and retain moisture.

Snail Secretion Filtrate: Claimed to aid in anti-aging benefits such as minimizing wrinkles and fine lines, firming and tightening the skin and boosting elastin and collagen production. Also said to help repair skin damage, heal wounds and burns, replenish moisture, and assist in reducing scars and skin pigmentation.

Hyaluronic Acid/Hydrolyzed Hyaluronic Acid/Sodium Hyaluronate: A humectant which absorbs moisture 1000 times its weight. Plays an important role of providing sufficient moisture to the skin, and helps bring back elasticity and lustre back to tired and sensitive skin.

Based on the ingredients, it can be observed that this sunscreen contains only chemical sunscreen filters such as Homosalate, Octocrylene, Ethylhexyl Salicylate, and Butyl Methoxydibenzoylmethane.

Furthermore, according to Skincarisma, there may be possible triggers for fungal acne (Polysorbate 80, Sorbitan Oleate). This sunscreen also contains drying alcohol (Alcohol Denat.), silicone (Diphenylsiloxy Phenyl Trimethicone) and essential oils (Bergamot Fruit Oil, Mandarin Orange Peel Oil, Basil Oil).

Hence, if sensitive to any ingredients stated above or any other ingredient listed, please do steer clear (or at least patch test before use to note down any possible skin sensitivity or irritation).

Volume: 35ml

How to use:

Apply a generous amount on over face 30 minutes before sun exposure.
Reapply throughout the day as needed, especially during prolonged sun exposure.

My Skin Type: Sensitive (prone to redness), Combination, Acne-prone, Dehydrated

Cosrx Shield Fit Snail Essence Sun SPF50+ PA+++ Review:

Similar to its green sister, the Cosrx Shield Fit Snail Essence Sun is packaged in a slim, travel-friendly squeeze tube with a screw cap, but with cheery yellow tones instead of calming green.

Again, Cosrx’s shift in packaging is very pleasing to the eye, and I love how fine-tipped the nozzle dispenser is as it enables the user to easily control the amount of product needed per application.

Now, unfortunately for me, having skin that’s more reactive than “normal”, I’ll just mention outright that the formulation for this sunscreen is not ideal. With Alcohol Denat. listed as its third ingredient, I already had my doubts, but splash in some essential oils midway, and yup, I already knew that my skin would be reeling in horror.

So unlike the Shield Fit All Green Comfort Sun which boasts an EWG all green grade formula, the ingredients list for this sunscreen was disappointing for me, to say the least.

But hey, let’s give it the benefit of the doubt, shall we?

As it does contain a few essential oils (Bergamot Fruit Oil, Mandarin Orange Peel Oil, Basil Oil), it’s not surprising that the scent of the sunscreen leans citrus-heavy with a touch of herbal-spice. Initially, it had a more obvious basic chemical sunscreen scent with a tinge of alcohol, but overtime, the essential oils have definitely taken over completely. It’s not a hugely irritating scent, so I don’t personally mind it too much, but it is moderately strong for those weary of scents.

The texture of the sunscreen is quite pleasant, in my opinion. It’s not necessarily an “essence” texture, but as soon as you spread out the light cream, it melts into a lovely cooling and moist texture, which is definitely a nice feel for parched skin.

However, Cosrx’s claim on the sunscreen leaving a “petal-like, baby skin soft finish” is not necessarily true in my experience. On the back of my hand, maybe, but when I apply it on my face in the recommended two-finger rule of sunscreen application, it has more of a dewy, almost greasy finish. So for those with oilier complexions, this might not be your cup of tea.

However, if you find your base makeup (foundation, cushion, etc) “cracking” due to lack of moisture or the finish being too flat matte, I find that this sunscreen makes an excellent moisturizing base to prevent potential flakiness.

Just be sure to also powder after all that because overtime, all that natural oil plus moisturizing base will definitely grease you up – might not be applicable to very dry skin types, though! Also, unlike its green sister, this Snail sunscreen leaves no white cast at all on my medium skin tone at all, so that’s great.

Now, I’ve been testing this sunscreen on and off for the past month to really get a feel for it, and while it does have its saving grace (it’s been great as a moisturizing base pre-makeup), it did unfortunately cause breakouts for me in the long run.

I can use it continuously for a few days, sure, but a week? Nope, my sensitive skin was just not having all that drying alcohol and essential oils (especially in a sunscreen).

So while I do find this to be more cosmetically elegant than the Shield Fit All Green Comfort Sun, I’d still pick that over this – at least my skin wouldn’t freak out; not to mention that the green sunscreen does have an extra “+” on its PA rating (the more UVA protection, the better!).

Overall, the Cosrx Shield Fit Snail Essence Sun SPF50+/PA+++ gets a 2.5/5 rating from me. It’s not a horrible sunscreen by any means, and it might work for others with drier, less reactive skin types as it does provide a nice moisturizing base for makeup, but it just doesn’t work for me in the long run.

Also, considering how pricey it is for just 35ml of product, I definitely feel like there are other cheaper (per ml) options on the market, preferably with “cleaner” formulations if you also suffer from sensitive skin.
