Query: Great lip sunscreen

I purchased this product on recommendation from my dermatologist. I love it for sunscreen and weather protection. I get sunburned easily and my skin is very sensitive, so it protects my lips well without irritation. It goes on smooth and feels great (moisturizing, not waxy.) It is very white and if you don't rub it in well you'll get white lips. Even when I rub it in my lips are a little lighter than my natural color. I've layered colored lip gloss on top with decent results, but I'd rather use it only when I need serious protection.
