Lip balms work by hydrating and protecting the lips, according to Dr Jason Thomson, head of medical at Skin + Me. Oils and waxes in the formulas form a barrier that locks in moisture, which is particularly helpful because the skin on the lips is thinner and lacks oil glands, making it more prone to dryness and chapping, especially in winter.
For daytime use, especially in summer, Thomson recommends a lip balm with broad-spectrum sun protection of at least SPF 30, applied every two hours. To maintain hydration, reapply regularly throughout the day—at least four times daily if treating dry, chapped lips.
After testing various balms for two months, we found Hello Sunday's formula with SPF 50 and hyaluronic acid to be one of the most hydrating. It has a clear, gel-like consistency that leaves a juicy sheen and creates the illusion of slightly plumper lips. Though waxy and thick, it is vegan, unscented, and non-sticky.
Bondi Sands' lip balm (SPF 50) impressed us with its nourishing properties, thanks to vitamin E and coconut oil. It has a thick, buttery consistency that melts into a lightweight layer, with a divine toasted coconut scent. It is reef-friendly, cruelty-free, and vegan.
Another standout is a rich, buttery balm formulated for cracked lips, with a sweet honey and citrus scent. Lavender honey and shea butter soothe and alleviate tightness, making it one of the most intensive hydrating balms we tried.
A do-it-all balm delivers lasting hydration, SPF 50, and a high-gloss finish in six sheer shades. With a soft peppermint scent and slight cooling sensation, it uses shea butter and cacao seed butter to keep lips soft and supple.
