Learn the correct way to apply sunscreen with Beauty of Joseon's Relief Sun Rice + Probiotics, including how much to use, layering, and reapplication tips for maximum protection.
Sunscreen is the most essential step in any skincare routine, yet many people apply it incorrectly, leaving skin vulnerable to UV damage. Whether you're new to daily SPF or looking to refine your technique, this guide will walk you through the correct way to apply sunscreen, using Beauty of Joseon's Relief Sun Aqua-Fresh : Rice + B5 (SPF50+ PA++++) as our star example.
The Relief Sun formula is a Korean sunscreen that combines rice extract and probiotics to soothe and hydrate while providing high-level protection. But even the best sunscreen won't work if you don't apply it properly. From how much to use to when to reapply, we'll cover everything you need to know for a flawless sunscreen routine.
Why Correct Sunscreen Application Matters
Many people assume that slathering on any amount of SPF is enough, but research shows that most people apply only 25-50% of the recommended amount. This drastically reduces the protection you get, leaving you exposed to UVA and UVB rays that cause premature aging, dark spots, and even skin cancer.
The correct amount is about 2 milligrams of sunscreen per square centimeter of skin. For your face and neck, that translates to roughly a teaspoon or the 'two-finger method' – squeeze sunscreen along the length of your index and middle fingers. This ensures you get the full SPF50+ protection promised on the label.
- Use the two-finger method for your face and neck.
- Don't forget often-missed areas: ears, hairline, and the back of the neck.
- Apply sunscreen as the last step of your morning skincare routine, before makeup.
Step-by-Step Guide to Applying Relief Sun : Rice + Probiotics
Start with a clean, moisturized face. After your moisturizer has absorbed (about 5 minutes), take a generous amount of the Relief Sun Aqua-Fresh : Rice + B5 (SPF50+ PA++++) – about the size of a pearl or the two-finger amount – and dot it onto your forehead, cheeks, nose, and chin.
Gently spread the sunscreen outward and upward using your fingertips. Avoid rubbing vigorously, as this can cause pilling and uneven coverage. Instead, use light patting motions to press the product into the skin. This helps the sunscreen form an even, protective film.
Wait 10-15 minutes for the sunscreen to dry down before applying makeup. This allows the film to set and ensures you don't disturb the protection. If you're using a cushion or foundation, apply it with a damp sponge using gentle patting motions rather than sweeping strokes.
- Dot sunscreen on five key areas of the face for even distribution.
- Use patting motions, not rubbing, to avoid pilling.
- Let the sunscreen set for 10-15 minutes before makeup.
How Much Sunscreen Should You Use?
The golden rule is to use at least a half teaspoon for your face and neck. For the body, you need about a shot glass full. Using less than this means you're getting lower protection than the SPF on the bottle suggests.
If you're using the Relief Sun Aqua-Fresh, you'll be pleased to know it has a lightweight, watery texture that absorbs quickly, making it easy to apply the full amount without feeling greasy. For touch-ups during the day, consider a portable option like the Glow Sun Stick, which makes reapplication easy and mess-free.

- Use half a teaspoon for face and neck.
- For the body, use a shot glass full (about 30ml).
- Reapply every 2 hours if outdoors, or after swimming/sweating.
Layering Sunscreen with Other Skincare Products
Sunscreen should be the last step in your skincare routine, but it's important to know how it interacts with other products. For best results, apply it after your moisturizer and before your makeup primer or foundation.
If you're using a toner like the Green Plum Refreshing Toner : AHA + BHA, make sure it's fully absorbed before applying sunscreen. The same goes for serums and essences. Give each layer a few minutes to sink in to prevent pilling and ensure even coverage.
For a complete morning routine, consider the Bright & Firming Duo, which includes a vitamin C serum to brighten and a sunscreen to protect. This pairing not only saves time but also ensures your skin gets both antioxidant protection and UV defense.
- Apply sunscreen after moisturizer, before makeup.
- Wait for each skincare layer to absorb.
- Pair with antioxidant serums for extra protection.
Reapplication Tips for All-Day Protection
One application of sunscreen is not enough for a full day. The FDA recommends reapplying every two hours, especially if you're outdoors, sweating, or swimming. But reapplying over makeup can be tricky.
For a quick fix, use a sunscreen stick like the Glow Sun Stick – it glides over makeup without smudging. Alternatively, you can use a setting spray with SPF or a powder sunscreen for touch-ups. If you're using the Relief Sun Aqua-Fresh, you can also apply a thin layer over your makeup using a beauty sponge, but be gentle to avoid disturbing your base.
Remember that even on cloudy days, up to 80% of UV rays can penetrate the clouds, so daily reapplication is key to maintaining protection.
- Reapply every 2 hours when outdoors.
- Use a sunscreen stick for easy touch-ups over makeup.
- Don't skip sunscreen on cloudy days.
Common Sunscreen Mistakes to Avoid
One of the biggest mistakes is using sunscreen that's past its expiration date. Sunscreen loses its effectiveness over time, so always check the PAO (period after opening) symbol. Another mistake is relying on makeup with SPF – you'd need to apply a lot of foundation to get adequate protection, so always use a dedicated sunscreen underneath.
Also, avoid applying sunscreen only on sunny days. UV rays are present year-round and can penetrate windows, so make SPF a daily habit, even if you're staying indoors. Finally, don't forget your lips – use a lip balm with SPF to protect this delicate area.
By avoiding these pitfalls, you'll get the most out of your sunscreen and keep your skin healthy and youthful.
- Check expiration dates and PAO symbols.
- Don't rely on makeup SPF alone.
- Apply sunscreen daily, even indoors or on cloudy days.
Applying sunscreen correctly is a simple yet crucial skill that can dramatically improve your skin's health and appearance. With the right technique and a high-quality product like the Relief Sun Aqua-Fresh : Rice + B5 (SPF50+ PA++++), you can ensure full protection without the greasy feel. Remember to use enough product, layer it properly, and reapply throughout the day.
