Seasonal Guide
Summer Fridays’ viral lip balm now has SPF 30 — but will it survive a sweat-drenched July afternoon without melting or disappearing?
Expert Analysis · Honest Reviews · Real Results
1.☀️SPF That Won’t Melt Off

I wore this during a 95°F day at the Brooklyn Botanical Garden. Sweat was literally dripping down my temples. The balm stayed put.

Most SPF lip products dissolve into a greasy puddle the second you step outside. This one actually clings to your lips like it’s afraid of the sun.

2.💄What’s in the Tube

Summer Fridays took their viral Lip Butter Balm and added SPF 30. $24. The claim that got me: “broad spectrum protection that feels like nothing.”

1

Sunscreen that doesn’t taste like sunscreen

Zero of that bitter chemical aftertaste. Genuinely shocking.

2

Butter-like slip

Glides on like a warm knife. Not sticky. Not waxy.

3

Sheer tint that actually shows

Two shades. Both are “your lips but better” — not that weird milky SPF white.

3.🧴Ingredients That Earn Their Spot

Avobenzone and octocrylene do the UV heavy lifting. But the real story is the butter blend — shea, mango seed, and cupuaçu — that keeps lips from turning into cracked desert floor.

  • Shea Butter: Deep moisture that doesn’t sit on top
  • Mango Seed Butter: Locks in hydration without greasiness
  • Cupuaçu Butter: Amazonian fat that feels lighter than shea
  • Avobenzone: The only FDA-approved UVA filter that actually works

4.🌡️The Sweat Test

First swipe: feels like a melted lip balm that somehow has structure. Silky, not slippery. Zero tack. I kept touching my lips to make sure it was still there.

Two weeks in, I noticed something weird — my lips weren’t just protected, they were actually softer. The SPF didn’t dry them out. That never happens.

💡

One Thing: Apply 15 minutes before sun exposure. Chemical sunscreen needs time to bind. Don’t be lazy.
5.💧The Honest Verdict

My lips didn’t burn once. No peeling. No reapplication panic. But I did reapply after eating — it’s not invincible, just stubborn.

Worth it?
Yes. $24 for SPF that doesn’t feel like punishment is a steal.
