I'm someone who relies heavily on lip balms. The current one I'm using from Labello doesn't have sunscreen but these pretty tubes from Fresh contain SPF 15.
Fresh's Sugar Lip Treatment SPF 15 in Colourless, Rose Tinted and Plum Tinted
They also contain no petroleum nor parabens. I'm also liking the fact that they contain sugar. There's something about sugar in skin care products that really hits home run with me. If I could choose, I guess I'd pick the plum tinted one.
