Why Dermatologists Prefer TiZO’s Formulas
Have you ever found yourself standing in the skincare aisle staring at sunscreen bottles, with no idea which one to pick? In this blog, we are breaking it all down for you (with a little science sprinkled in), so you know why dermatologists are consistently reaching for TiZO’s mineral-based formulas.
Understanding Photodamage & Why Sunscreen is Non-negotiable
When you first step outside, feeling the sun on your skin makes you want to sigh happily, but prolonged UV exposure does a lot more than just give you a glow. Photodamage, also known as photoaging, happens when your skin is exposed to UV radiation over time. It doesn’t just affect how your skin looks; it changes its very structure. Here’s what can happen:
collagen breaks down
elasticity weakens
skin texture becomes rougher
wrinkles, sagging, freckles, and sunspots become more noticeable
leathery texture sets in for some
Over time, these effects can go beyond aesthetics, significantly increasing the risk of skin cancers, including melanoma. In other words, that “just a little tan” is really your skin showing signs of damage.
UVA vs. UVB Rays: What’s the Difference?
Understanding the two main types of UV radiation is key to understanding why sunscreen matters so much. UVA rays are the “aging” rays. They account for most of the UV radiation reaching Earth and can penetrate the dermis and epidermis deeply.
On the other hand, UVB rays are the “burning” rays. They don’t penetrate as deeply as UVA and target the surface layers of the skin. They’re at their strongest during spring and summer between late morning and mid-afternoon. These rays cause sunburns and, more dangerously, damage DNA in skin cells, making them one of the leading culprits in skin cancers.
Together, UVA and UVB make a powerful case for why you need a sunscreen that provides broad-spectrum coverage, shielding against both aging and burning rays.
Mineral vs. Chemical Sunscreen: The Comparison
So, what’s the real difference when it comes down to your skin? Mineral sunscreens like the ones offered by TiZO provide a physical barrier that reflects UV rays immediately, using zinc oxide and/or titanium oxide. Chemical sunscreens rely on multiple synthetic compounds, which need time to activate and can be less gentle on the skin. Dermatologists overwhelmingly recommend mineral sunscreens for their effectiveness, gentleness, and safety, for both your skin and the environment.
Why Dermatologists Prefer TiZO
Dermatologists consistently recommend TiZO because it elevates mineral sunscreen beyond the basics. Unlike traditional zinc oxide sunscreens that can leave a thick white cast, TiZO’s formulations are silky, blendable, and even come in tinted versions that double as a makeup primer.
Because zinc oxide alone provides comprehensive broad-spectrum protection, there’s no need for chemical combinations, which reduces the risk of irritation. That makes TiZO products ideal for everyday wear and sensitive, acne-prone, or post-procedure skin. It’s medical-grade protection wrapped in an elegant finish you’ll actually want to wear daily.
Choosing the Right Sunscreen for You
When selecting sunscreen, choosing one that fits both your lifestyle and your skin’s unique needs is important. Look for broad-spectrum protection at SPF 30 or higher and prioritize mineral-based options for the most comprehensive coverage. If you wear makeup, TiZO's tinted sunscreens are a perfect match, offering both coverage and protection in one step. The key is finding a formula you’ll enjoy applying every day because consistency is what keeps your skin truly protected!
The Bottom Line
Photodamage is serious business, and it’s caused by both UVA and UVB rays working against your skin in different ways. Chemical sunscreens may help, but they don’t compare to mineral protection's simplicity, safety, and effectiveness. With TiZO’s dermatologist-preferred mineral sunscreens, you’re not just protecting your skin today, you’re preserving its health and beauty for years to come.
If you’re ready to make the switch, explore TiZO's tinted sunscreens to find the perfect mineral formula for your skin type.
