Having dry or dehydrated skin can be the absolute worst—take it from someone who knows. Lately, my skin has been so dehydrated that I've had to switch up my foundation options because some of them are far too drying for everyday wear. It's definitely frustrating, but if you also struggle with dryness, you've come to the right place.
I've recently learned a few things when it comes to skin that's dry vs. dehydrated, and that's all thanks to celebrity esthetician Renée Rouleau. I asked Rouleau to share her knowledge on dryness, dehydration, the skin's moisture barrier, and more. She also shared the best hydrating serum to help keep your skin nourished. Keep reading—there's lots of important knowledge ahead.
Dry Skin vs. Dehydrated Skin
"Dry skin lacks natural oils and is something you're genetically predisposed to," she says. "We also become more prone to it as we age. Dehydrated skin lacks water and is a temporary condition that anyone can have. Both dryness and dehydration can disrupt barrier function." It's important to know the difference between the two and how each plays a role in the function of your moisture barrier.
Your Moisture Barrier and How Its Health Can Cause Skincare Issues
There are a few different ways your skin could be dehydrated, and they can cause some real damage to your moisture barrier, something that Rouleau also says is the main cause of most skincare issues: "In my 30-plus years of experience, I have seen that pretty much every skin concern can be traced back to (or exacerbated by) a damaged moisture barrier. There are so many conditions that indicate a damaged barrier—redness, dryness, irritation, increased breakouts… The list goes on. The moisture barrier acts as your skin's personal bodyguard, keeping the good stuff in and the bad stuff out. When it's compromised, small cracks appear, allowing moisture to escape and irritants to enter, leading to all of these issues!"
If you're noticing any of these issues and your skin has become increasingly dry, Rouleau has a few extra tips. "Use a moisturizer that mimics the skin's barrier structure with ingredients like ceramides, phospholipids, shea butter, and plant oils such as jojoba," she says. "You can also use an essence to help reintroduce hydration into the skin." Another great way to boost hydration in the skin is by adding a deeply hydrating serum to your routine so that your skin can begin to repair itself and get the nutrients it needs. For a rec from Rouleau along with my own favorites, keep scrolling.
"My Skin Drink Concentrate is a great option to infuse hydration back into the skin—I like to say it's like a tall glass of water for your skin!" Rouleau says.
