What the gurus are saying

This mist earns consistent praise for calming irritated skin and refreshing the complexion, especially useful after sun exposure, treatments, or throughout humid days. The mineral content, particularly high in the thermal water, has been shown in studies to support healthy skin microbiota diversity, making it especially helpful before applying hydrating serums or moisturizers to boost absorption. One important caveat: while dermatologists find it pleasant and soothing, a few note it's a luxury rather than essential, if budget is tight, products that already contain thermal spring water deliver the same benefits without needing a separate mist. Those with sensitive skin testing actives like retinoids may appreciate that it's glycerin-based without hyaluronic acid, so it won't sting on compromised skin.

"If you're hot at the beach and you want a nice hydrating spray while you're hanging out, this is a nice spray to cool down. If you want to do this at night before you go to bed and you want to get a nice hydrating moisturizer or serum to help lock in and absorb all that moisture you got from this, go right ahead. But if you have a burn, this is also really nice to just soothe. This is a very calming soothing spray that you could consider."
~Yay
"The Thermal Spring Water from La Roche-Posay is something I often recommend to my patients with really dry skin. Spritz it on the skin first because there's high mineral content, and it's been shown in studies to increase the microbiome diversity on the skin, giving more varied types of good bacteria, before you follow up with your moisturizer."

"There is data to support that La Roche-Posay's spring water, which is high in mineral content, increases the microbial diversity on the skin. Recently I was in La Roche-Posay, France at their treatment facility, where patients bathe in this spring water, shower in it, get massages in it, get jet therapy in it, and it's an intensive 21 day treatment course that really helps with some of these complicated skin diseases like eczema, psoriasis, burns, the side effects of cancer treatment, and other types of scars."

Barrier Care for Cold Weather Skincare Routine
"I just did a misting of the La Roche-Posay thermal water spray. I've been really into it lately because that little layer of mist seems to help with the absorption of everything else that's something that I've been noticing. I'm really picking this up because it is not just water, right? It's thermal water and it's got these vitamins and minerals in here that are actually really good for your skin microbiome. It's a super duper gentle product, but your skin microbiome is your skin's first line of defense and it does work in tandem with your skin barrier to keep your skin protected."

"I'm going to use the La Roche-Posay thermal water spray just to put a layer of just wetness on my skin and that really helps the PDRN essence spread and as well as absorb into the skin. A little bit of misting really helps."
~Yay
"It's really nice for soothing skin, calming skin, nice for use after cleansing. It applies pretty evenly as well, so if you want to apply a little bit of it before you put makeup on it works well for that. No fragrance, really affordable option. I did a BBL treatment and a Moxy laser, and they sent me home with a little bottle of this and I went out and bought the giant one. For two to three hours after that treatment my skin was very unhappy, red, irritating. But anytime I misted this my skin instantly calmed down for like a second or two and then I'd mist again. It's pretty simple. It's got their Thermal Spring Water which has some benefits. I'm thinking there's a thermal bath where people with really bad eczema and skin rashes and allergies can go and bathe in the thermal water. It's really nice for that."
~Yay
"I'm a big fan of the La Roche-Posay Thermal Spring Water. Every time I'm traveling I always use it before I go on a beach. What I do is I put it in the fridge, pull it down and then put it in an ice pack, and if I'm out there I use [...] it to spray just to cool down, and in case somebody gets a sunburn it's a nice cooling spray to have. It always comes in handy."
~Mixed
"You don't need it, it does feel nice to spray, and if you're especially somebody who likes to spray water before you apply your hyaluronic acid, this is something that can give you that added boost. You don't need it, but if you're extra you might like it, extra in the summer. I love it, I love doing like a Thermal Spring Water spray and then like a hyaluronic acid drippy and then like a lightweight moisturizer, like if I'm in Arizona or Colorado somewhere horribly dry and barren, that will save my skin."
~Yay
"I'm a fan of soothing waters, so sometimes I like to incorporate La Roche-Posay's thermal [...] water into my routine after cleansing."
~Yay
"You can bring this to the beach and freshen up your skin because sometimes if you're outside for a long period of time in the summer and you're wearing sunscreen daily and you keep reapplying it, it can make your skin feel really tight. This just gives that nice refreshment and that moisture to the skin. Great to use on top of your makeup and sunscreen throughout the day. [...] This is one of my favorites for sure."
~Yay
"The other drugstore brand in the misting category that I've used for years is La Roche-Posay, another brand I think can do no wrong. It is called the Thermal Spring Water. Throughout the day you will often see me at my desk like a weirdo just doing this, they've come to accept it, it's who I am now."
~Mixed
"This is now discontinued. I always had it to hand because it had a beautiful mister and it didn't sting at all. The reason I use this is when I'm testing retinoids because when you put hyaluronic acid onto sensitized skin it can sting or burn, but this doesn't sting because it's glycerin based with no hyaluronic acid."
~Mixed
"It doesn't appear to be harmful, and it may have some skin benefit, but this is not essential, I would say it is a luxury item. The research on things like atopic dermatitis, psoriasis, and rosacea is pretty small, and you have to take it with a grain of salt because La Roche Posay funded it themselves. If you are on a tight budget, this can of water would be the first thing to cut from your routine. Stick to skincare products that already contain Thermal Spring Water so you can still get those benefits without needing another separate product."
