For most sunscreens, you should be reapplying every two hours when you're in direct sun, and immediately after swimming, sweating, or towel drying. For the most accurate instructions, please refer to the individual product packaging.
And yes, you can reapply sunscreen over makeup. That's exactly why we created Naked Sundays Hydrating Glow Mist SPF50, a lightweight SPF mist designed to refresh your protection without disrupting your makeup.
How Often Should You Reapply Sunscreen?
The first application in the morning is just the beginning.
For most sunscreens, the recommendation is to reapply at least every two hours when you're in direct sun, and immediately after swimming, heavy sweating, or towel drying.
Why? Because sunscreen is a protective layer that needs to stay evenly distributed on your skin. Throughout the day, things like sweat, touching your face, clothing, towels, and everyday movement can reduce that coverage.
SPF top-ups are what help you maintain the required sun protection throughout the entire day.
Why Does Sunscreen Need Reapplying?
Sunscreen isn't permanent once it's on your skin.
Heat, sweat, water, towels, and even everyday activities can gradually wear away your sunscreen layer. That's why reapplication is a must when it comes to wearing SPF, it's not an optional extra step.
Think of your morning sunscreen as your starting point. Your midday top-up is what keeps your protection going.
How Often Should You Reapply Sunscreen?
Always follow the directions on your sunscreen label, but as a general guide:
-
In direct sun: reapply every two hours.
-
After swimming or sweating: reapply immediately once skin is dry.
-
After towel drying: reapply because the towel can remove your sunscreen layer.
-
During everyday outdoor moments: a midday top-up can help maintain your protection, especially if you're commuting, walking, driving, or sitting near windows.
Can You Reapply Sunscreen Over Makeup?
Yes! This is where many SPF routines fall apart. Most people aren't removing their makeup at lunchtime to start their skincare routine again, and you shouldn't have to.
A lightweight SPF mist makes reapplication much easier. The right formula can add another layer of protection while helping your makeup stay fresh.
Our bestselling Hydrating Glow Mist SPF50 was created for exactly this moment. The ultra-fine mist helps refresh your SPF over makeup without the need to start your entire routine again.
Just remember, always follow the product label, especially for water activities or heavy sweating.
How Do You Reapply Sunscreen Without Ruining Makeup?
- Hold the mist 20 to 25 centimeters from your face.
- Close your eyes and mist in a slow X pattern, then an O around the perimeter, until skin feels evenly misted. One quick spritz is not enough.
- Wait 30 seconds before touching your face.
- Repeat per the label instructions, typically every two hours in direct sun or immediately after swimming, sweating or towel drying.
- Make sure to avoid your eye area.
What Counts as "Enough" When You Top Up?
More than feels natural. With a mist, you should keep going until the whole face feels evenly covered. If you finish a top-up wondering whether you used too much, you probably used the right amount.
Do You Need to Reapply Sunscreen on Cloudy Days or in Winter?
Yes, especially if you're spending time outdoors. Clouds can reduce some UVB rays, but UVA rays are present year-round and can pass through windows. If you're walking outside, driving, sitting near large windows, or spending extended time outdoors, keeping up your SPF habit is super important.
The easiest sunscreen to reapply is the one you actually enjoy using, which is why a lightweight mist can make such a difference.
