Deep-Sea Vegan Collagen Super Serum

Deep-Sea Vegan Collagen Super Serum

First on my list is Tarte’s Deep Sea Vegan Collagen Super Serum. It helps to nourish and hydrate the skin by using a blend of eight different oils. It refreshes the face, giving it a supple radiance. It also brightens and plumps the skin on your face to give you a more youthful appearance. This incredible serum contains bi-phase oil +essence, which provides antioxidant benefits. If you’re looking for a do-it-all serum, this is it. 

The great thing about this product is that its dermatologist tested. It’s been proven to provide greater hydration and skin elasticity after four weeks of use.

Here are some of its skin invigorating ingredients:

Argan oil

This lightweight oil consists of fatty acids and antioxidants to deliver full nourishment to the skin.

Marine plant extracts

This ingredient minimizes the look of fine lines by softening and smoothing wrinkles.

Vegan marine plant collagen complex

Your face will look firmer and feel more hydrated because of this amazing ingredient.

Sodium hyaluronate

Sodium hyaluronate provides your skin with extra firmness, suppleness, and moisture.

How to Apply Deep Sea Vegan Collagen Super Serum


This product is pretty simple to use. Just make sure that you shake it well before applying it to your skin. If you have dry or normal skin, then apply a layer of the product underneath your moisturizer. On the other hand, if you have oily skin, use this serum to replace your moisturizer.

The Pros and Cons Of Deep Sea Vegan Collagen Super Serum

There are a lot of incredible benefits of using this product. I’ll start off by explaining the good stuff first.

No Harsh Ingredients

You can feel confident knowing that your skin won’t be subjected to harmful ingredients. Tarte’s Deep Sea Vegan Collagen Super Serum is formulated without mineral oil, parabens, gluten, triclosan, phthalates, or sodium lauryl sulfate.


If you live a vegan lifestyle and you want all of your products to be vegan, you won’t be disappointed with this serum. It’s made with a vegan collagen cocktail that does an incredible job.

Dermatologist Tested

When it comes to your skin, you want to make sure that you’re using a quality product. Since this serum is dermatologist tested, then you know it’ll provide pretty good results.

The Cons

Believe it or not, there’s not a lot of bad things to say about this serum. It has so many good reviews—not only from myself—but other customers as well. However, there might be one downside.

The Price

This serum isn’t too expensive, but that depends on who you ask. If you don’t like spending more than $20 on facial products, then you won’t be too happy about the price point of this serum. It costs about $40. But the good news is, the Tarte website actually allows customers to pay in installments. So, if you don’t have the money to pay for it all at once, just break it up into payments. Problem solved!

Knockout 10% Acid Complex Serum

Okay, next on a list we have Tarte’s knockout 10% acid complex serum. It’s a 5-in-1 AHA serum containing a 10% glycolic & lactic acid blend to offer a more youthful appearance. It helps to hydrate and brighten the skin, as well as retexturize it. It’ll enhance the firmness of your face while also reducing the look of your pores. It’s formulated with the standard asset pH level of 3.7, therefore it’s gentle for all skin types. 

Furthermore, this serum includes coenzyme 10, which is an ingredient that helps to promote collagen production. If you have sensitive skin, don’t worry. Tarte’s knockout serum doesn’t contain any synthetic fragrances that will irritate your face. It also consists of vegan squalene and aloe to help soothe your skin.

This dermatologist-tested product provides better-looking skin within 2 weeks of use. Here’s a more in-depth look at some of its skin invigorating ingredients:

Lactic acid

This ingredient gently exfoliates and hydrates the skin while stimulating cellular renewal for a more youthful appearance and plumper skin.

Vegan squalene

Vegan squalene helps to hydrate the skin, plus it retains moisture and improves elasticity.

Glycolic acid

When you need deep exfoliation, this ingredient does the job. It invigorates dull-looking skin to create a healthy, radiant complexion.


This is an antioxidant that’s vitamin-rich and soothes the skin.

How to Apply Knockout 10% Acid Complex Serum

This incredible face serum works best as part of a nighttime skin routine. You’ll want to cleanse your face with Tarte’s knockout cleanser, then apply your serum, and add a Tarte moisturizer on top.

The Pros and Cons of Knockout 10% Acid Complex Serum

There’s no doubt that this product works incredibly well. But I’d be wrong if I didn’t provide you with the pros and cons of this serum. As always, we’ll start with the pros first.

No Harsh Ingredients

As with most Tarte products, this particular serum does not contain any harsh ingredients. That means that it’s formulated without mineral oil, parabens, gluten, triclosan, and sodium lauryl sulfate. You can feel confident knowing that you’re only putting the best products on your face.

Shrinks Pores

If you have large pores, this serum will make them look noticeably smaller. Sometimes beautiful skin isn’t just about blemishes or wrinkles, but the pores too. If they’re large, they can take away from the smooth look of your skin. Thankfully, this product helps to take care of that.


Tarte’s knockout 10% acid complex serum is vegan and cruelty-free. If you are someone who does not like the idea of testing on animals, then this product is a game-changer. You don’t have to feel guilty about using this product at all.


If your skin doesn’t like a lot of heavy moisturizers and oils, you’ll love this serum. It’s extremely lightweight, and it won’t leave a greasy residue. If you prefer to use facial products that don’t leave your skin feeling clogged and hot, this is a great option.


Although this serum isn’t heavy, that doesn’t mean it strips your skin of moisture. Some products are notorious for pulling moisture out of the skin instead of adding to it. Thankfully, you won’t have that issue with this product.

The Cons

Below are the not-so-good things about Tarte’s knockout 10% acid complex serum :

Not a Daytime Serum

Obviously, you can use this serum whenever you’d like, and it’ll work just fine. However, this product works best as part of a nighttime routine. When you use it in conjunction with other Tarte skincare and allow it to work on your face as you sleep, you’ll see good results. If you’re looking for a daytime serum to protect your face while you’re out and about, this isn’t the best option.

The Price

As stated above with the previous product, this serum is expensive depending on who you ask. It’s moderately priced at about $40, which isn’t bad for a quality serum. However, if it’s out of your budget, you’re still in luck. This product can also be paid for in installments!

Mermaid Skin™ Hyaluronic H2O Serum

tarte mermaid skin

Last, but certainly not least on my list is Tarte’s Mermaid Skin™ Hyaluronic H20 Serum. It’s a water-light hydration serum that gives an instant burst of moisture to dry skin. It provides 24-hour hydration, and it’s full of hydrating ingredients like hyaluronic acid, marine plants, and vitamin b5. 

All of these powerful ingredients offer an incredible antioxidant defense. Also, this invigorating water-gel formula instantly absorbs into the skin. With this fantastic formula, you’ll receive healthier, glowing skin and a visibly brighter appearance. Here are some of this product’s skin-invigorating ingredients:

Marine plants

This ingredient helps to minimize the appearance of fine lines and wrinkles while also softening the skin.

Hyaluronic acid

Your skin will receive firmness, suppleness, as well as moisture through this powerful ingredient.

Vitamin B5

This ingredient offers deep moisture to hydrate and soothe the skin.

How to Apply Mermaid Skin™ Hyaluronic H2O Serum

It’s actually quite easy to apply this product. You can either spritz it directly onto your skin or spray a couple of pumps on your hands and gently rub it across your face. It’s that easy!

The Pros and Cons of Mermaid Skin™ Hyaluronic H2O Serum

I’m pretty sure you know the drill by now. I have to give you the good and the bad aspects of this product. So, here goes the good:

Easy to Apply

Unlike the other two serums, this product is extremely easy to apply. It comes with a spray pump, so you can actually use it on the go. It’s perfect for pulling out of your purse when your skin needs a little hydration—especially during the cold months. You can’t go wrong with this one!

No Harsh Ingredients

I know I keep repeating myself, but I have to bring this up. There are no harsh ingredients in this product. So, just as the other two serums didn’t contain triclosan, phthalates, gluten, sodium lauryl sulfate, or mineral oil…neither does this one. Listen, these types of ingredients can really wreck your skin. Therefore, you’ll feel extra good knowing that you’re not putting any of those damaging substances on your skin.

24-Hour Hydration

How can you beat 24-hour hydration? Honestly, you can spray this product on in the morning, and it’s guaranteed to hold you over until the next day. Again, during the dry winter months, it’s so easy for the skin to start to lose its moisture. But with this serum on hand, you don’t have to worry about that.

Water-Gel Formula

This serum offers a boost of lightweight hydration. It provides your skin with that instant invigoration that it needs. Therefore, you don’t have to worry about any greasy residue on your skin after applying this product.

The Cons

Okay, there aren’t too many bad things to say about this particular serum, but here are some of its downsides:

Not Specifically for a Skin Routine

Okay, this serum provides many benefits for the skin. But as I stated before, it’s more of a quick hydrator. If you’re looking for a serum to use as part of a steady skin routine, you’ll want to find something to use in conjunction with this spray.

The Price

You’ll have to spend a little over $40 on this product. That’s not bad considering all of the incredible results that it provides. But as I stated before, Tarte allows its customers to pay for products in installments. So, you’re good to go!


Question: Should I Replace My Moisturizer With a Serum?

Answer: Of course, moisturizers and serums have different textures. Serums tend to be more lightweight, and feel great on the skin. However, depending on your skin type, you may have to play around with the option that’s best for you. 
If you have oily skin, then serums might be the better option. They’re more lightweight, but they still provide your skin with the hydration that it needs. On the other hand, you may find that switching up your skin routine is better. For instance, serums might work well for the summer, and moisturizers will keep your skin more hydrated during the winter because they generally consist of thicker formula.

Question: How Do I Choose Between the Tarte Serums?

Answer: Well, I’ve already given my opinion about the Tarte product that I feel is the best. But everyone is different. The only way to know which one is right for you is through trial and error. If you use one and it doesn’t provide your desired results, then don’t be afraid to test out another one.

Question: How Do I Know If These Are Good Products?

Answer: Tarte products are dermatologist tested. The company has done plenty of trial and error with its skincare products to ensure that they are ready to go on the market. For example, the Mermaid skin serum was tested on 34 individuals in a clinical study. The other two serums were tried and tested with another group of people as well. Therefore, you don’t have to feel like you’re putting an untested product on your face.

Question: When Can I Expect to See Results?

Answer: It depends on the type of results that you’re looking for. If you’re trying to reduce the size of your pores, minimize wrinkles, or remove blemishes, that’ll take some time. But many users saw improvements in their skin and as little as two weeks using these Tarte serums. Actually, some users saw instant improvement. Anytime you cleanse your face and apply a great product, it’s going to make your skin look clean, supple, and hydrated. 
So, even if you simply apply the product, it’ll make your skin look great as soon as you put it on. But for more in-depth results, you’ll want to be consistent with the product. Per the serum that you choose, follow the instructions on the bottle and consistently use the product for the recommended amount of time before throwing it in the towel.

Question: How Do I Pay for My Tarte Products in Installments?

Answer: It’s actually quite simple. Choose the products that you want, and when you go to the checkout, select Afterpay. Next, log in or create an Afterpay account. Once you’ve completed that step, you’ll be able to split the purchase into four installments and make a payment every two weeks.

The Best Tarte Face Serum-My Choice

Drum roll please…my choice for the best Tarte facial serum is the Deep Sea Vegan Collagen Super Serum. It really is a do-it-all serum. It includes so many incredible benefits, and it offers fantastic results. You can use it as part of a steady skin routine, and you’re guaranteed to see results.

The other two products are great, but they are lacking a bit when it comes to their uses. For instance, the knock-out serum is best for nighttime, and the mermaid serum is primarily an on-the-go product.

Of course, you’re free to use these serums any way that you’d like to. This isn’t to say that the other two can’t be used in the daytime or however you choose to apply them to your skin. I just feel as though the Deep Sea Vegan Collagen Super Serum is the best option. After all, they don’t call it a super serum for no reason! Do you think you’ll try it out?
