As a celebrity makeup artist, living and working in the San Francisco Bay Area, people are always asking me about my favorite skincare and beauty finds. I test a lot of products throughout the year, so when something genuinely earns a place in my routine, I love sharing it.

One of my newest discoveries is the Espoir Water Splash Sun Serum, and I was pleasantly surprised. I recently spotted it at Costco, and after trying it, I completely understand why so many people are talking about it.

The first thing I noticed was the texture. It feels much more like a lightweight hydrating serum than a traditional sunscreen. It glides onto the skin, absorbs quickly, smells fresh without being overpowering, and leaves my skin looking healthy, hydrated, and naturally radiant. There’s no heavy or greasy feeling, and best of all, no white cast.

As someone who spends my days working with skin, I love products that multitask. The Espoir Water Splash Sun Serum combines SPF 50+ protection with skincare ingredients like hyaluronic acid, caffeine, and carnosine to help hydrate and refresh the skin. It’s a simple way to protect your skin while giving it a boost at the same time.

One thing that really impressed me is how beautifully it performs under makeup. It creates a smooth, hydrated canvas, so foundation glides on beautifully without pilling or feeling heavy. That’s something I always pay attention to because if a sunscreen doesn’t work well under makeup, most people won’t use it consistently.

One thing I remind my clients all the time is that sunscreen isn’t just for vacations or days at the beach. We should be protecting our skin every single day. Whether you’re driving, walking the dog, playing golf, meeting friends for lunch, or simply running errands, your skin is exposed to UV rays.

We invest so much in skincare, facials, and makeup, but protecting your skin every day is one of the smartest beauty habits you can have. Prevention is always easier than correction.

If you’ve been searching for a sunscreen that feels like skincare instead of a traditional SPF, I think this one is definitely worth checking out. I found mine at Costco, and it’s also available online. If it’s sold out online, keep an eye out for it in your local Costco warehouse. It’s worth getting it before it sells out!

Beautiful makeup starts with beautiful skin… and beautiful skin starts with protecting it.

Healthy, protected skin never goes out of style.

Have you tried the Espoir Water Splash Sun Serum? I’d love to hear your thoughts—or let me know your favorite sunscreen. I’m always excited to discover products that help us look and feel our very best.

Christina’s Pro Tip: Apply sunscreen as the final step in your skincare routine every morning—even on cloudy days. Give it a minute or two to absorb before applying makeup. Your skin will thank you today, tomorrow, and years from now.
