When during the day should I apply this strawberry and rose lip balm, and how do I use the stick correctly? — PL Lip Balm Strawberry and Rosehip 4.4 g

The PURE LINE Lip Balm Strawberry and Rose 4.4 g is a stick balm designed for quick, finger-free application. Because it forms a thin surface film that helps reduce moisture loss from the lips, it is most useful right before you go outdoors into wind or cold air, after a hot drink that can dry the lip surface, and whenever the lips start to feel rough or tight during the day.

• Twist the base only as far as needed to expose a small amount of balm.
• Glide it evenly across both lips in one or two passes; there is no need to rub it in with fingers.
• Reapply as often as feels necessary, since the layer wears off through eating, drinking and talking.

Lip skin has fewer natural oil glands than other facial areas, so a light protective layer is easy to lose and benefits from repeat application rather than one heavy coat. The subtle glossy effect and hint of natural-looking colour mean it can be worn alone or over bare lips without the weight of a lipstick. If you use it in the morning before makeup, let the film settle for a minute so subsequent products do not slide. Store the closed stick at room temperature and avoid leaving it in direct sun or a hot car, as stick balms can soften and become harder to apply cleanly.
