I'm currently studying away, which means makeup has taken a bit of a back seat and the desk essentials have come to the forefront again. This means thermal waters are the ideal little products to have sitting beside the laptop, if for nothing other than to wake me up halfway through the day!
They do more than that though, and this La Roche-Posay offering is the ideal spritz to have on hand for sleepy/dry/dehydrated skin. Just as it says, it's literally a thermal spring water that can be used to freshen up makeup (they're perfect to mist over foundation), to spray on a cotton pad to make sure you have no residue of cleanser on the skin, or just to wake up (or cool down) bare skin.
It's an ideal skin companion, for long days at a desk or even to bring on holidays as a fresh cool mist to soothe the skin in the heat. At 8.99 (on Boots here) for 150ml it's at a similar price point to other offerings, like Avene's Spring Water.
Have you tried La Roche-Posay's Eau Thermale? Do you think thermal waters are effective or do you see any point?
