☀️ SPF Isn’t Optional: Why Sunscreen is a Must (and Why It Has an Expiration Date)

We love a golden glow as much as anyone, but sun protection is non-negotiable. Whether you're applying a full face of makeup or just running errands bare-faced, SPF is your skin’s best defense against premature aging, sun damage, and skin cancer. But did you know your SPF has a shelf life too?

Here’s why sunscreen should be in your daily beauty routine—and why checking the expiration date is just as important as checking the label.

🧴 What SPF Really Does

SPF, or Sun Protection Factor, measures how well a product shields your skin from UVB rays—the ones responsible for sunburns and DNA damage. Higher SPF = more protection, right? Sort of.

• SPF 30 blocks about 97% of UVB rays

• SPF 50 blocks around 98%

• Anything beyond that? Marginal difference, but reapplication is key.

And don’t forget UVA rays (hello, fine lines and wrinkles!). Broad-spectrum SPF protects from both UVA and UVB rays—look for it on the label.

⏳ Yes, Your SPF Expires (And That Matters)

Sunscreen isn’t wine—it doesn’t get better with age. Most SPF products last about 2–3 years unopened, but once opened, their effectiveness starts to degrade.

• Why it matters: Expired SPF may not protect you properly, leaving you exposed.

• How to tell: Look for an expiration date or open jar symbol (e.g., "12M" = 12 months after opening).

• Storage tip: Keep it cool. High heat (like leaving it in your car) speeds up breakdown.

If your sunscreen has changed texture, smells off, or separates—it’s time to toss it.

🧴💄 SPF in Makeup: Helpful or Hype?

Yes, your foundation or moisturizer might contain SPF—and that’s great! But here’s the catch: you’re likely not applying enough to get the full level of protection advertised.

SPF-infused products are a great bonus, but they shouldn’t replace your dedicated sunscreen step. For true protection, layer an SPF underneath your makeup and reapply with a powder or setting spray that contains SPF throughout the day.

🌞 How to Make SPF Part of Your Daily Routine

1. Apply SPF 30+ daily, rain or shine.

2. Reapply every 2 hours (more if you’re sweating or swimming).

3. Use a broad-spectrum formula for complete UVA/UVB protection.

4. Don’t forget ears, lips, and the tops of hands—they age too.

5. Check expiration dates regularly—especially before beach season.

🔥 Beauty For Real Pro Tip:

Pair your SPF with lightweight, longwear makeup like our Hi-Def Mascara and Shadow STX—designed to withstand the heat, the humidity, and even a dip in the pool. Because protection shouldn’t mean compromising your look.
