You’ve heard it a time or two—wearing sunscreen every day is one of the best ways to protect your skin. But applying once in the morning isn’t quite enough. Reapplication is key to keeping your skin happy, healthy, and protected in the long run.
Whether you’re heading to the beach, out for errands, or working near a sunny window, here’s everything you need to know about how (and how often) to reapply your sunscreen—with or without makeup.

Do I really need to reapply sunscreen?
Yes! Even the most advanced sun protection needs a refresh throughout the day. That’s because UV filters can move around and even break down with sun exposure, sweat, touch, and time—making reapplication essential. Without it, your skin isn’t getting the level of defense it deserves.
According to dermatologists and the Skin Cancer Foundation, reapplying sunscreen at least every two hours is the gold standard, especially if you’re spending time outdoors or around windows.
And here’s why it matters:
- Sun damage is cumulative—every unprotected moment adds up
- Daily sunscreen use can help prevent up to 80% of visible skin aging
- Consistent application helps reduce the risk of skin cancer
Your skin remembers everything—so keeping it protected throughout the day truly makes a difference.
How often to reapply sunscreen
Do your best to follow the expert rule of thumb:
- Reapply every two hours during sun exposure
- Immediately after swimming, sweating, or towel drying
- More often, if you’re in intense sunlight or high altitudes
Expert tip: Even indoors, UVA rays can penetrate through glass. If you’re near windows during the day, keep reapplying.
Going makeup-free? 4 tips for topping up
Here’s the ideal way to reapply sunscreen on a bare-faced day:
- Gently blot your skin with a tissue or quickly cleanse to remove shine or excess oil
- Apply a generous amount of sunscreen—use the two-finger rule for the face
- Don’t forget easy-to-miss areas: around the nose, hairline, ears, and neck
- Let it settle for a few minutes before moving on
Remember: the amount you apply matters. Using less than recommended can lower the level of protection.
How to reapply sunscreen over makeup
If you’re wearing makeup, don’t worry—you can still touch up your sun protection without smudging your look. Try these two easy steps:
1. Use a tinted sunscreen
A multitasker like Eryfotona Ageless gives you high SPF protection, a hint of color, and a smooth finish. Pat gently over makeup for a fresh touch-up. Bonus: it’s packed with skin-loving ingredients, such as DNA Repairsomes®, antioxidants, and peptides.
2. Set with a mineral powder
After reapplying sunscreen, lock in the look with a mineral powder like ISDIN Mineral Brush.
It’s great for on-the-go defense against photoaging and helps reduce shine—without altering your makeup. Keep it in your bag for easy reapplication.
Making it a habit
Like any skincare routine, consistency is everything. These simple tips can help you remember to reapply without overthinking it:
Pair it with another habit
Link reapplication with something you already do—like brushing your teeth after lunch or your afternoon coffee. Habit-stacking makes it easier to follow through.
Set reminders
A little nudge never hurts. Try setting a phone reminder every 2 hours when you know you’ll be out and about.
Keep products within reach
Store a travel-size sunscreen in your bag or desk. When it’s easy to access, it’s easier to use.
A little goes a long way
Reapplying sunscreen might seem like a small act—but it’s one of the most powerful ways to protect your skin. Whether you’re bare-faced or trying out a new makeup look, there’s a sun care solution to fit your needs.
Remember to check in with your skin throughout the day today—it’s worth it for healthy, happy, beautiful skin tomorrow.
