What makes waterproof makeup waterproof?

14 Apr.,2024

 


There’s nothing worse than spending your precious time working on a beautiful makeup look only for it to quickly smudge, fade or melt off. Fortunately, there are a plethora of waterproof makeup formulas on the market you can choose from to avoid this from happening again. But have you ever found yourself looking at your all-time favorite waterproof foundation or mascara and wondered, “What exactly makes this product waterproof?” We’ve been there, too. It all comes down to the ingredients and how it’s formulated. Ahead, we break down what makes makeup waterproof — plus the best anti-H2O formulas you can depend on for a look that stays put.

 

What Makes A Product Waterproof?

Unlike regular makeup products, waterproof makeup formulas are specifically formulated with safe ingredients and properties that resist and stay put when exposed to water, according to L’Oréal Associate Principal Chemist Roselin Rosario-Meléndez. The formulas usually contain a film former, which Rosario-Meléndez describes as a large molecule that, when spread, forms a water-binding film that covers the substance’s surface continuously. Many of the film formers found in waterproof makeup, she says, are silicone- or acrylate-based polymers, which help foundation, eyeliner or other makeup products stick to your skin.

 

Waterproof Vs. Water-Resistant: What’s The Difference?

Waterproof and water-resistant makeup are often mistaken for one another, but there are actually some important differences between the two that you should keep in mind. A waterproof formula is one that is meant to withstand just about anything (think: going for a swim). A water-resistant formula, on the other hand, can only resist the penetration of water to some degree (think: sweating or crying). So if you’re looking for makeup that won’t budge or transfer no matter what, keep scrolling for our top waterproof picks for your makeup bag.

We’ve heard it before and we’ll hear it again: If you’re a beauty lover who has difficulty maintaining a full beat for hours due to sweat or physical activity, waterproof makeup is made for you. These anti-H2O formulas do an excellent job of keeping your mascara in place and making sure your foundation doesn’t slip. We tapped L’Oréal Associate Principal Chemist Roselin Rosario to find out exactly how they work. Here’s what she had to say.

 

Waterproof Makeup Is Formulated Differently

According to Rosario, waterproof and regular makeup formulas are very different, but they may contain some of the same ingredients, depending on what the product is. “Waterproof formulas are specially formulated to resist and stay put when exposed to water — so they contain adhesive materials that make the product stick to the skin,” she says, adding that the only thing that can remove them are oil-based removers.

 

What Ingredients Make Makeup Waterproof?

As far as the actual ingredients that help impart waterproof properties, fill formers are the golden ticket. “A film former is typically a large molecule that, when spread, forms a film that covers the substance’s surface continuously,” says Rosario. “There are many adhesive film formers that give waterproof properties, and most are silicone- or acrylate-based polymers.” Additionally, these film formers are carefully chosen to create the formation of lightweight and breathable films, in order to ensure a comfortable wear on the skin. “Other water-soluble ingredients are also used to reinforce the system and give even stronger water resistance.”

 

How Waterproof Makeup Is Tested

Before a waterproof product leaves the lab, every formula is thoroughly tested to make sure that it will actually withstand water. According to Rosario, the water resistance of a formula is first tested in vitro by applying the product onto a material that resembles the intended area of application (like a false eyelash), and water is then applied to see if the product gets removed. “Formulas that do not pass the in vitro tests are either abandoned or reformulated,” she notes. “Then the formulas are tested on humans to check their performance and ensure that they are indeed waterproof.” That’s right, every product from the L’Oréal Paris Air Volume Mega Mascara Waterproof to the Maybelline New York Super Stay Matte Ink Liquid Lipstick goes through a round of IRL testing on people before it hits the market.
