If you're serious about skincare, chances are sunscreen is already part of your daily routine—or at least, it's supposed to be. Yet despite how essential it is, sunscreen is one of the most misunderstood products in the beauty world. With so many myths floating around, it’s easy to get confused about what’s actually true.

In this blog, we’ll break down some of the most common sunscreen myths—and set the record straight, once and for all.

Myth #1: You Only Need Sunscreen on Sunny Days

This is probably the most persistent myth out there. The truth? UVA and UVB rays can penetrate through clouds, windows, and even in the winter. That means whether you’re out for a morning walk or working near a window, you still need SPF.

The best Korean sunscreens are formulated not only for outdoor use, but also to be lightweight enough for indoor wear, too. Products like the Beauty of Joseon sunscreen are designed for everyday protection without leaving a greasy finish or interfering with your makeup routine.

Myth #2: High SPF Means You Don’t Need to Reapply

SPF 50? Great. But that doesn't mean you're protected all day. Sunscreen breaks down over time—especially with sweat, oil, or sun exposure—so reapplying every 2–3 hours is key to maintaining protection.

Korean sunscreen SPF 50 options, like those from Beauty of Joseon or Isntree, provide strong protection, but they still need to be reapplied if you’re out and about.

If you're looking for convenience, go for a travel-size sunscreen so you can reapply easily throughout the day—no excuses!

Myth #3: Sunscreen Is Only for Dry Skin Types

Another myth that keeps many women with oily or acne-prone skin from using sunscreen is the idea that it will clog pores or make your face look greasy.

Thankfully, that’s no longer true—modern Korean skincare sunscreens are specifically formulated to work with all skin types, including oily and sensitive skin. The gel-like textures, matte finishes, and non-comedogenic ingredients make them ideal for sunscreen for oily skin needs.

If you’ve been skipping sunscreen because of oily skin, now’s the time to change that habit.

Myth #4: Makeup with SPF Is Enough Protection

It’s tempting to think your BB cream or foundation with SPF 15 has you covered. Unfortunately, that’s not true unless you're applying several layers of it—which most of us aren’t.

Even if your makeup includes SPF, it doesn’t replace a dedicated sunscreen layer underneath. Use a lightweight, breathable formula like the Beauty of Joseon Relief Sun, which acts as a moisturizer, primer, and sun protection—all in one.

Then apply your makeup on top as usual. This simple step boosts your protection and keeps your skincare routine clean and simple.

Tips to Maximize Your Sunscreen’s Effectiveness

• Apply generously—about two fingers’ length for the face and neck

• Reapply every 2–3 hours, especially when outdoors

• Use daily, rain or shine, summer or winter

• Pair with antioxidants like vitamin C for extra protection

• Choose sunscreen based on your skin type (hydrating for dry, gel or matte for oily)

Conclusion: Don’t Let Sunscreen Myths Fool You

Sunscreen is one of the simplest, most effective ways to protect your skin from aging, sun damage, and even skin cancer. Yet myths and misinformation keep too many women from using it properly.

Korean sunscreens—like the beloved Beauty of Joseon SPF 50—make it easy, enjoyable, and even luxurious to add SPF into your daily skincare ritual.

Whether you’re new to sunscreen or just want a formula that fits your skin better, the right product makes all the difference. Skip the myths—your skin deserves the truth.
