Kristina Holey + Marie Veronique Soothing B3 Serum

I’ll be honest–I do not always get excited about trying new beauty products, unless something about them really stands out: ingredients, technology, an extraordinary collaboration. This is the case for the Kristina Holey + Marie Veronique Collection.

You may already be familiar with Marie Veronique and her beautiful skincare line. It is science-based and nature-powered. You may also have heard about Kristina Holey, a facialist and skincare expert with a holistic approach. This includes whole nutrition and healthy lifestyle recommendations (my cup of tea, for sure), not too mention that she has trained with the renowned French skin expert, Joëlle Ciocco. The collection* (to be precise, the 2/3 serums I have tried so far), ended up not only meeting my expectations — it exceeded them and has me hoping for more magic to happen in the lab in the future.

The collection includes three products, which are face serums that target different skin concerns. So far, I have only tested two out of the three, and the one I am reviewing in this post is my favorite: the Soothing B3 Serum. Let me tell you, it’s called soothing for a reason.

What Is It

A gel serum suited for all skin types; especially beneficial to sensitive (generally intended as skin types that are sensitive to several ingredients, irritants, allergens, prone to inflammatory reactions), and breakout-prone skin types. Also described as microbiome-friendly, as it promotes a healthy balance of bacteria on the skin. (Yep, in case you didn’t know, your skin is covered in bacteria–but don’t freak out! It’s meant to be that way.). When your skin is healthy, these microorganisms live happily together, in harmony with each other. However, changes in your skin can allow pathogens to grow and cause inflammatory conditions. So a microbiome-friendly product is meant to help to keep the bacteria in balance and prevent inflammation (which can lead to acne breakouts, rosacea, eczema, and more).

How It Feels

The lightest gel you’ve ever tried–kinda runny and watery-like. A slightly (very slightly) sticky after-feel upon the application goes away completely once the product is absorbed into the skin — likely from the hyaluronic acid in the product, which typically feels a bit sticky. It feels hydrating and soothing. Once it is absorbed, there’s no residue left on the skin. I tend to get a bit flushed after cleansing (my tap water irritates my skin), but the combination of my hydrating toner and this serum makes my skin feel calm and won’t allow it to develop redness. If you have tried aloe vera gel on irritated skin — this feels similar on the skin (that cooling/refreshing/soothing effect), but waaaay better.

What’s In It (Stand-Out Ingredients)

ECGC (compound found in green tea), green tea extract, hyaluronic acid, D-panthenol, licorice root, niacinamide (vitamin B3), carrot root extract, knotgrass flavonoids. I love that all the ingredients are beneficial, and that it is free of cheap fillers and meaningless ingredients.

What’s Not In It

No questionable ingredients at all. It is free of fragrance and essential oils. It is also oil-free, which makes it a great product for combination and oily skin types as well. In fact, I think that this would be an excellent option during Spring/Summer when combination skin types need hydration, but also have to avoid heavy, oily products.

How I Use It

After cleansing and using a hydrating toner, I apply 2-3 pumps of Soothing B3 Serum all over my face and neck. I also apply it on my under-eye area. It absorbs quickly, so there is no need to pat it into the skin over and over. I just massage it gently until it is evenly distributed. Some days I don’t apply any other product on top of this serum, because my skin feels and looks so great. Sometimes, (usually during the weekend, when I do a face mask), I apply a light face oil blend (Argan oil + Wild Carrot Serum Oil) on the areas of my face that may need a little more love, like around my lips and where my laugh lines appear when my skin is dehydrated.


The finish left on the skin is slightly dewy, and absolutely non-greasy. My skin looks fresh and plump after the application.

Immediate Benefits

The first thing I notice after application is that my skin looks and feels plump, hydrated, and calm. As someone who is prone to redness, this product has a soothing effect on my skin but it does not leave the uncomfortable residue that many other products with the same effect leave on my skin (oils, creams, balms, etc).

Ingredient L♥ve

Niacinamide. There is plenty of evidence to back up the benefit claims made for niacinamide. It can effectively improve skin’s barrier function preventing moisture loss.

It is also beneficial to rosacea sufferers: in patients with rosacea, one study found that a moisturizer with niacinamide as its active ingredient improved inflammatory lesions, scaling/peeling, dryness, and erythema.

Finally, niacinamide can improve the appearance of aging skin by smoothing the surface of the skin and the fine lines.

ECGC. This is a compound found in green tea. When applied topically, it has skin, photo-protective, and photo-repairing properties. I wrote a more detailed post about this ingredient here.

Hyaluronic Acid. Naturally found in the skin tissue, hyaluronic acid has moisture-binding properties. It helps to prevent moisture loss and boost moisture levels in the skin. Therefore, HA is an ideal ingredient for all skin types (especially if dehydrated) that can give the skin a more smooth & plump appearance.

D-Panthenol. Also known as Pro-Vitamin B5, it is converted to pantothenic acid when applied to the skin. Its humectant properties effectively improve dryness, roughness, and scaling of the skin as shown in several studies.

Full Ingredients List

Camellia sinensis (Green tea) extract, sodium hyaluronate, niacinamide (vitamin B3), D-panthenol (pro-Vitamin B5), sodium salicylate, n-acetyl glucosamine, Epigallocatechin-3-gallate (ECGC), gluconolactone, polygonum aviculare extract (knotweed bioflavonoids), daucus carota sativa (carrot) root extract, Beta-glucan, galacto-oligiosaccharide, bacillus ferment, leuconostoc / radish root filtrate ferment, Glycyrrhiza Glabra (Licorice) extract, Cucumis Sativus (Cucumber) Fruit Extract

Comparison/Similar Products

I haven’t tried anything that feels or works like this one so I can’t compare it to any similar product.

Final Thoughts

A product with these characteristics (oil-free, hydrating, soothing) is something that was missing in my skincare routine and that I am grateful to have found. I have currently used half of the bottle (I have been using it for a couple of months), and I foresee myself continuing to reach for it in Spring and Summer, especially when the alternating of the humid and hot temperatures outdoors and the cool, dry indoor air typically make my skin freak out. I love the finish it leaves on my skin because it works well under sunscreen for the daytime and directly under makeup in the evening. Therefore, I will be buying a new bottle as soon as I run out of it. Totally recommend it *inserts the praying hands emoji*.

I plan to also have my husband starting to test it on his skin because he is currently dealing with dermatitis and I will update this post once he has used it long enough to understand how it works for him.

That being said, I think someone with dry or very dry skin types may prefer to use it in combination with another product, perhaps layering a light face oil on top to further help seal the moisture in.

If you are interested in learning a bit more about the Kristina Holey + Marie Veronique collaboration, read this interview. I plan on reviewing another one of the three serums from the collection (the Barrier Restore Serum) soon. Spoiler: another winner and staple. I have yet to try the Intense Repair Serum, which is recommended to skin types that are prone to breaking out because I do not typically get breakouts anymore. So hopefully I will not have the chance to test it out at all and will pass it along to someone who needs it. Gotta stay optimistic and keep that positivity going, guys.

The Soothing B3 Serum is available at Ayla Beauty.

    So great to see you back Lilly! I so agree that this is a missing step in so much of green beauty! As much as I love my sprays and oils, there is just something lacking. Do you think I can use this serum if I use a Vitamin C? I read that niacinamide and Vitamin C are could be irritating to skin.

    • Hi Krista, thank you for reading and sorry for the delay. Great question about niacinamide and vitamin C! From what I read, the major concerns are that the two ingredients could cancel each other’s benefits and/or that they could cause irritation. I am going to turn your question to a few experts and keep you posted. My suggestion would be to use your Vitamin C product in the morning and niacinamide in the evening.

    Would love to hear what you experience is with the Skin Barrier Serum……

    • Hi Evan, I am currently writing it and should be posting it soon :) Thank you for reading!

    Would love to hear/read what you think about the Skin Barrier Serum….

    Hi Lilly! Thank you for your sharing. I’ve always been finding a product which is oil free and contains green tea and some soothing ingredients. My question is about this high concentration of Niacinamide in this product. I read from some material that 2% of Niacinamide is ideal for sensitive skin, the higher concentration, the higher irritation may happen. As far as I know, this B3 serum contains 10% of Niacinamide. This is the only reason I hesitate to try it.

    • Hi Peppa, thank you for reading! I understand your concern about the Niacinamide concentration because my skin is sensitive to many ingredients and so easily irritated. However, I found this serum to be more soothing to my skin than anything else I have tried. I recommend you try a sample first, which you can order here: I hope this helps! Please let me know if you have anymore questions :)

        Thank you Lilly! It’s very kind of you. I will let you know how do I like it after I try:)
