Water Resistant’ refers to how long a sunscreen stays intact on wet skin.
It determines how long it takes before a sunscreen loses its effectiveness if your skin is in contact with water.
Remember when buying sunscreen was simple?
You’d just pick an SPF level, check if it suited your skin type, and that was it.
Now, it feels like navigating a maze. The crowded shelves with technical jargon like SPF, PA, and broad spectrum make the choice trickier than ever.
But among this, there’s one label most people still overlook—water-resistant.
So let’s understand what it means because that small label might be the reason your sunscreen isn’t doing its whole job.
1. Are sunscreens waterproof?
There's no such thing as waterproof sunscreen. All sunscreens start to wear off once they come in contact with water, sweat, or friction.
And we’re not the ones saying this.
It’s what regulators like the U.S. Food and Drug Administration (FDA), Therapeutic Goods Administration (TGA) in Australia, and the Cosmetic Products Regulation (CPR) in Europe firmly state.
The term is actually banned from being written on sunscreens.
Instead, ‘water-resistant’ is the word you should look for.
2. What does ‘Water Resistant’ in Sunscreens mean?
According to the FDA and CPR, ‘water resistant’ refers to how long a sunscreen stays intact on wet skin. Based on this duration, products are labelled ‘water resistant’ or ‘very water resistant’.
It determines how long it takes before a sunscreen loses its effectiveness if your skin is in contact with water.
And to understand that, it’s important to define the difference between a water-resistant sunscreen and a very water-resistant sunscreen.
3. Water Resistant vs Very Water Resistant Sunscreens
FDA, CPR, and equivalent regulators worldwide mandate specifying the exact time for which a sunscreen maintains effectiveness when exposed to water.
Given that, here’s what the terms imply:
Water resistant: Remains effective for 40 minutes
Very water resistant: Remains effective for 80 minutes
| Type | Duration In Water | Use Cases |
| Water Resistant | 40 minutes | Short sun exposure, light sweating, and everyday physical activities |
| Very Water Resistant | 80 minutes | Prolonged water exposure, extreme water sports or physical activity like workout, swimming, indoor and outdoor sports |
