Meet your new go-to SPF for breakout-prone skin!

Say hello to EltaMD UV Clear Blemish-Prone & Oil-Balancing SPF 50—a lightweight sunscreen designed specifically for oily, acne-prone skin.

✨ Why we love it:
• Helps reduce visible blemishes + oil
• Minimizes the look of pores
• Broad-spectrum SPF 50 protection
• Lightweight, blends easily, and wears well under makeup
• Non-comedogenic (won’t clog pores)

Powered by 5% niacinamide and calming zinc oxide, this formula doesn’t just protect your skin—it helps improve it over time.

If you’ve struggled to find an SPF that doesn’t feel heavy or trigger breakouts, this is worth trying.
