Best Overall Alternative
RESIST Youth-Extending Daily Hydrating Fluid SPF 50
Paula's Choice·Chemical Sunscreen
See alternatives- Size: 59.1 ml
- Price per ml: $0.66/ml (original $0.76/ml)

Both recommended for Sun Protection.
“It is watery like a milky toner, so it soaks in and doesn't leave a film.”

Best Cheaper Alternative

The why

One minus
Fragrance is overpowering
Good forSensitive Skin
Both recommended for Sun Protection.
“I also wanted to mention that I've FINALLY found a daily sunscreen that works under makeup, goes on perfectly matte, and doesn't irritate my rosacea or cause my PD to have an outbreak.”
