My Review of Simple Invisible UV Fluid SPF 50
I haven’t tried anything from Simple for years, and as SPF is one of my favourite topics, I was keen to test this out.

First Impressions

From the very first application, I noticed how super light yet hydrating the texture is. It’s more like a silky serum than a traditional SPF, and it blends into the skin immediately and effortlessly. There’s no white cast and no greasy residue.
Hydration Without the Heaviness
Even though it’s feather-light, it still feels hydrating, which is perfect for my combination skin. It has that comfortable, barely-there feel that makes you forget you’re even wearing SPF. And it’s easy to top up.

Good Under Makeup, if you go gently
This SPF sits nicely under makeup if you apply your foundation gently, as it dries down to a natural finish. This means it doesn’t change the look of your base products. If you go in with too much product and too hard, the sunscreen can pill a tiny bit, but it is managable.
Skincare Ingredients for More Than Just Protection
Aside from UVA and UVB protection, this SPF is also uses impressive skincare ingredients. There are antioxidants and brightening agents that help tackle hyperpigmentation and improve the overall look and tone of the skin. Over time, it’s not just protecting against future sun damage, it’s also helping to make your skin look healthier and more even.
Super Affordable
We all know SPF is something you should be using every day and generously, which means affordability really matters if you’re on a budget. The Simple Invisible UV Fluid SPF 50 is super affordable, making it easy to apply the recommended amount without worrying about cost. This is key, because using too little SPF is one of the biggest reasons people don’t get the full protection they need.
Final Thoughts
The Simple Invisible UV Fluid SPF 50 is the kind of product you’ll actually want to use every day, and that’s the most important thing when it comes to SPF. It’s light yet hydrating, blends instantly, feels super comfortable, works under makeup if you’re gentle, and makes reapplication easy. The added skincare benefits are just the icing on the cake.
