  • Messy packaging wastes product

What the gurus are saying

This serum draws instant plumping hydration into skin and earns consistent praise for calming redness and irritation, making it especially useful after treatments or for sensitive skin. The standout caveat is packaging: reviewers report the spray dispenser wastes product and applies unevenly, though the results are strong enough that some use it daily regardless. Those with fragrance sensitivity may want to patch-test first, and a few find it feels tacky on the skin until fully absorbed, best applied to damp skin and layered under moisturizer for maximum hydration.

"I use the La Roche Posay Cica Plus Baume B5 spray. It has Panthenol which is soothing, paired with some Cica, which is soothing as well. And I just like the spray form. It is nice, hydrating, and soothing."

"It's my favorite hyaluronic acid serum. I remember first using this in 2020 when I was introduced to a lot more skin care than I usually am exposed to as a medical dermatologist. When I first used this, I loved how plumping it was. It really draws in water, causes that instant plumping effect. It does have a little bit of a scent and fragrance, and I like it. It's very nostalgic to me. It reminds me of when I first started this YouTube channel. It also has panthenol, which has moisturizing and hydrating effects, great for supporting the skin barrier. It's one of my essentials."

The Top FIVE Must-Have La Roche-Posay Skincare Prdoucts!
"After your cleanse in the morning, you go ahead and put on a hydrating serum, a hyaluronic acid serum specifically. This one is the La Roche-Posay Cicaplast B5. One of my favorite all-time products from them. Hyaluronic acid is a nice carbohydrate that will draw in water, plump up the skin. So, while your skin's damp, go ahead and apply a few drops of this to your face. And what I love about this is that it is very plumping. One of the easiest ways to hide fine lines and wrinkles is to apply hyaluronic acid serum followed by a moisturizer to seal that in. And the smell of this, it just brings me back. I started using this in 2020 when I had to shut down my clinic and started up social media. When I smell the fragrance from this serum, it really does bring me back to taking long walks with my kids and starting up social media. That's the beauty about skincare. It's a sensorial experience. It feels great. You want products that make you feel more confident and also you like the texture of it, how it blends into your skin, but also the smells and scents and fragrances."
Retinoid Irritation Explained by a Dermatologist | Skin Barrier Adaptation Science
"If you really want to work on the skin barrier and you're feeling pretty raw and you like serums, La Roche-Posay has a Cicaplast spray B5 with the niacinamide and panthenol. So you can start off with this. Do a little spritzing over the face. It's refreshing after the gym. This is different from having damp skin when you apply your retinoid. This is actually going on like a moisturizer. It feels like it's hydrating my skin. It's soothing. It's going to help repair the skin barrier with the niacinamide and the panthenol."

She's tried many different hyaluronic acid serums and that one for her is a big winner. It picks up all that moisture. Then layer over it with a moisturizer or a moisturizer with SPF. It's a nice boost of hydration and glowy texture before a big event, say going on the news or going to a holiday party, going to a reunion. You want to get that hydration boost, go ahead and do a hyaluronic acid serum."

But if you are allergic to fragrance, if you have a known allergy to fragrance, then probably not for you."

"My favorite still though has to be La Roche-Posay Hyalu B5 serum still my favorite Hyalu B5 man it's just packed with hyaluronic acid that's a water sponge that draws in water and it just keeps it all there and it really plumps up my skin it feels so great and if you have a big event and you want to have a little plump dewy look use that it does have fragrance though so it has this familiar smell that I'm totally okay with and I love that smell so familiar works well on my skin but if you have a true fragrance allergy then maybe not for you"

"For best hydrating serum I would recommend the La Roche-Posay Cicaplast B5 hyaluronic acid serum. This serum combines hyaluronic acid with vitamin B5 which is a soothing ingredient that helps repair the skin barrier. It's particularly effective for sensitive skin as it's hydrating without any irritation. The key ingredients here are the hyaluronic acid, vitamin B5, and niacinamide. Hyaluronic acid has nothing to do with actual acids. It's a misnomer in my opinion because a lot of people think it's going to be irritating because it has the word acid. It's really a completely hydrating serum. The best time to apply this is on damp skin and you can still apply moisturizer on top. Though a lot of moisturizers nowadays have hyaluronic acid in them. If your skin is really dry, mature and you want extra hydration, applying hyaluronic acid serum on damp skin followed by a regular AM moisturizer is going to really help lock that moisture in and plump your skin."

"This one also has a little bit of vitamin B5, which is a really soothing ingredient that's going to help repair the barrier. It provides that immediate sustained hydration and it's really good if you have sensitive skin and if you're really really dry. You want to apply it to damp skin for optimal hydration effects."

"My next recommendation for acid is the Lash Pay Hyalo B5 serum. This one can also be used morning or evening. This one does have just a little bit of that LRP scent. It's really nice. It's delicate. It's soft. It's more nourishing option if your skin is really dry and sensitive. I find a little bit more hydrating than the L'Oreal one. It also helps target those fine lines and dullness really just by replenishing the moisture. It has a little bit thicker texture but absorbs really quick. It sits really well under your moisturizer or underneath the SPF. Just like with the other one, I like to put moisturizer right on top. And I like to apply my HA serum on damp skin. I feel like it does the best job at moisturizing. The key ingredients are vitamin B5 or [panthenol], hyaluronic acid, and mcaside."
Dermatologist’s Guide to Choosing the Right Serum for Your Skin
"One of my favorite recommendations in this category is La Roche-Posay Cicaplast B5 serum. The serum combines hyaluronic acid with vitamin B5, a soothing ingredient that helps repair the skin barrier. It's particularly effective for sensitive skin as it's hydrating without any irritation. Some of the key ingredients are hyaluronic acid, which helps draw moisture to the skin for a plump, hydrated complexion. It also contains vitamin B5, known for its calming and healing properties, and it works to improve skin resilience and barrier function. It also contains madecassoside, which is derived from Centella asiatica. This ingredient has soothing and anti-inflammatory effects, making it great for sensitive skin."

"This has 5% of panthenol as well as matrycide for hydrating the skin, strengthening the skin barrier, but also soothing any irritation. I've been using this product actually for a while, and I do like what's inside of the bottle. It's a little bit hydrating, but very soothing, very comforting. Helps to take down some redness. I really don't like the mist because it is, as you heard and saw, it's just a traditional kind of pump. It's a very uneven spray. But you know what? I really like what's inside of here. And it's just a really nice way to get started with the routine for some deep soothing from the matrycide, which is the biologically active compound of Centella. And so it really helps with the anti-inflammatory, taking down the redness, the itchiness, the irritation."

"I have been using it now for a while. I've used about half the bottle, and I do like this with reservations. This has 5% of panthenol in it. It has madecassic acid, which is the biologically active compound of Centella. And it's really soothing. It's actually so amazing for irritation. It really calms the skin down, reduces redness, inflammation, itching. Panthenol is hydrating and barrier supportive. I like this as a soothing and calming spray. You could use it like a really lightweight toner. I don't find it incredibly hydrating probably because of the very light layer that this spray delivers, and I just tend to like a lot of hydration. I would say it's hydrating. There is an element to it. It's much more hydrating than just a thermal spray for sure. I mostly use this when my skin is irritated. Something like this is perfect. It really does soothe on contact in a nice way."
Yay
"This one's a really nice one. You can just mist it. I'll mist it like right when I get out of the shower, all over my whole body. It's got panthenol and niacinamide. It's got micaceous, another centella-derived ingredient, and cocoa. It's really nice. It's got a nice even mister on it, too. Sometimes I'll just the second I get out of the shower to hold on to any moisture I have, I'll just spray it. So it's nice for that."

La Roche-Posay 🆕 Cicaplast B5 Soothing Repair Spray for Dry Skin Review, How to, & Dupes
"It does a nice job calming skin down and could be nice for use after a treatment or if you use a laser, microneedling, whatever. It's nice for that. Or if your skin's just irritated, it's a nice option for that. For what it promises to provide, 24-hour hydration, repair skin barrier, invisible texture, I would say this helps repair the skin barrier, does not provide 24-hour hydration. So don't count on that, but it does help moisturize it. And you can use it throughout the day, unless you're using it over makeup. Then you might have mixed results. It does have a slight layer effect, like almost a light sticky feeling to it once it soaks in, but it's not terrible. It's not shiny or anything like that. This one's going to be friendly for all skin types, dry, oily, normal, sensitive, acne prone. No acneic ingredients, so that makes it nice for everyone to benefit from it. The full size is 100 milliliters, 3.38 ounces, which is 25 bucks, which isn't terribly expensive, but it is starting to creep up there. I would expect to see this run at like 19.99. That's what I would have expected, but anyway, everything's getting more expensive. In terms of the IT factor, it's not a must-have."

"The La Roche-Posay Cicaplast mist contains their centella ingredients which help calm skin, help with redness, prevent irritation, soothe irritation, and it also is great for hydrating skin. Really pretty short ingredient list on this one as well. No fragrance, niacinamide, which is great for helping your skin heal and calm down. This is probably the line of theirs I use the most because it doesn't have fragrance in it. A lot of their other stuff has too much fragrance in it but this stuff is nice."

"You would think the La Roche-Posay Cicaplast B5 Face Serum would be amazing, and it's not amazing but it's also not bad. It's nothing compared to the Cicaplast cream. It's nice but it's just fine, it could work, maybe, I enjoyed it. The one thing putting this in the middle is the packaging: you end up losing a lot of product and it gets really messy, so you lose more than you actually use."

"I have a real love-hate relationship with this one. I was late to the game but I'm in love with their products, absolutely love with the La Roche-Posay Cicaplast line in general. The packaging pisses me off every time I use it, it's messy, it's dirty, you waste a lot of product. But I love the results so much and how it soothes and calms and hydrates my skin, reduces that redness on my skin, any irritation. Vitamin B5 in here, amazing, amazing. I'm able to look past the packaging purely because of how much my skin loves this. I kind of love the serum more than the moisturizers. For me it's kind of like an everyday use thing, I can use morning and evening."

Testing New & Hyped Skincare Products...They're OK 😬
"I've been using this every time I travel to London because the water there makes my skin feel so dry, irritated, red and rough. I go straight for Cicaplast and my moisturizers to help heal and soothe, and this serum has been doing a really nice job. Two weeks in so far so good. My skin's been stinging a lot recently but this doesn't sting at all. I really really like this. I would highly recommend getting it if you already love the Cicaplast line or if you just want a daily protective kind of serum and restoring serum."
Mixed
"One of the negative sides I personally find is it does feel a little bit tacky and sticky on the skin, and so with that I personally actually just use it where I need to, to target anywhere that I need want some plumping and hydration. But otherwise, some people really love the texture of this. For me I would say if there's anything negative to say about the serum is that it does for me at least feel a little bit sticky and tacky after it's fully absorbed. The other thing too is it is fragrance, and that's the other thing if people who have sensitive skin or at least sensitive to fragrance, this serum may not be the best."
Yay
"I want to get back on my La Roche-Posay Cicaplast gel because when I was using that around my eyes, man, it really had a drastic effect in tightening the skin on my eyes. I got a little trouble on my upper eyelids and so they've been kind of dry and irritated, but that is a great skin protectant for around your eyes for reducing eyelid irritation. We have all sorts of aerosolized allergens here, pollen, molds, and if you're into cooking certain spices and things they can end up causing eyelid irritation because they settle on the eyelids. The skin there is thin, so I really like that product as an eyelid skin protectant for eyelid dermatitis, for preventing it by protecting the skin and for healing it as well. It's glycerin based, and in contrast to other balms, it is a lot more hydrating and it doesn't go on opaque white. It's clear and colorless."

"I love the spray because it is so hydrating. It's got anti-inflammatory and soothing properties, perfect for if you're going to be using something irritating like a retinol. On top of the fact that it has panthenol or B5, it also has madecassoside, which is an extract of centella asiatica, so anti-inflammatory soothing properties. This is something that I love to just rehydrate my skin with."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.

Source: DermNet

Vitamin E

Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
