Common Sunscreen Myths (and What to Know Instead)
Sunscreen is one of the most important steps in any skincare routine—but it’s also one of the most misunderstood.
At Ohara Dermatology, Dr. Ohara Aivaz often sees patients who are doing their best with skincare but are unknowingly misinformed when it comes to sun protection. With spring here and more time spent outdoors, understanding how sunscreen actually works can make a meaningful difference in how well you protect your skin.
Let’s clear up some of the most common myths.
Myth #1: “My Makeup Has SPF, So I’m Covered”
While SPF in makeup is a great bonus, it’s usually not enough on its own.
To get the level of protection listed on the label, you would need to apply much more product than most people typically use. In addition, makeup isn’t reapplied throughout the day the way sunscreen should be.
For proper protection:
Apply a dedicated sunscreen first
Then layer makeup on top
Myth #2: “Higher SPF Means I’m Protected All Day”
It’s easy to assume that a higher SPF means longer-lasting protection—but that’s not how sunscreen works.
Even high-SPF products wear off over time due to:
Natural skin oils
Sweat
Daily activity
No matter the SPF, sunscreen should still be reapplied every 2 hours when outdoors.
Myth #3: “I Don’t Need Sunscreen Indoors”
Many people skip sunscreen if they’re not planning to be outside—but UV exposure can still happen indoors.
UVA rays can pass through windows, which means exposure can occur while:
Driving
Sitting near windows
Working in bright spaces
Over time, this can contribute to skin aging and uneven pigmentation.
Myth #4: “Darker Skin Doesn’t Need Sunscreen”
All skin tones can benefit from daily sun protection.
Even though melanin offers some natural protection, it does not prevent:
Hyperpigmentation
Melasma
Signs of aging
Consistent sunscreen use helps maintain a more even skin tone and overall skin health.
Myth #5: “If I Apply It Once in the Morning, I’m Good”
Applying sunscreen in the morning is a great start—but it’s only the first step.
Sunscreen gradually breaks down throughout the day. To maintain protection, especially during outdoor activities, reapplication is key.
Myth #6: “Sunscreen Feels Too Heavy for Daily Use”
This is a common concern, especially for patients with oily or acne-prone skin.
The good news is that modern formulations are much more lightweight and designed for different skin types. There are options that are:
Oil-free
Non-comedogenic
Lightweight and breathable
Finding the right sunscreen can make daily use much easier.
What Dr. Ohara Aivaz Recommends
To keep things simple, effective sun protection comes down to consistency.
Dermatologists recommend:
Using a broad-spectrum sunscreen (UVA + UVB protection)
Choosing SPF 30 or higher
Applying sunscreen every morning
Reapplying when spending extended time outdoors
Why Getting This Right Matters
Many of the skin concerns patients want to improve—such as uneven tone, dark spots, and early signs of aging—are closely tied to everyday sun exposure.
Without consistent sun protection, it can be difficult to maintain results from treatments or skincare products.
A Simple Step That Makes a Big Difference
Sunscreen doesn’t have to be complicated. Choosing a formula you like and using it consistently is what matters most.
As we move into longer, sunnier days, it’s a great time to refine your routine and make sun protection a habit that fits easily into your lifestyle.
If you have questions about choosing the right sunscreen or want guidance on addressing sun-related skin concerns, Dr. Ohara Aivaz is here to help guide you with personalized care.
