We tested 37 US lip balms to find those that soothe and hydrate.

A panel of 29 testers evaluated 37 US lip balms for hydration, tint, flavor, SPF and irritation, and two dermatologists were consulted about ingredients, allergies and product lifespans.

A review asked 29 volunteers, aged from their 20s to their 90s, to test 37 US lip balms over up to a week. Testers assessed flavor, tint, smell, SPF, dryness, extreme chapping and overall satisfaction. The review included long‑standing drugstore products, viral brands and recently reformulated formulas. Two dermatology professors were consulted to explain ingredient roles, allergy risks and product expiry. Key findings: - Twenty‑nine testers tried no more than four balms each (the lead tester tried every sample) and rated multiple attributes including hydration, scent and willingness to repurchase. - Experts explained that balms work through humectants, occlusives and emollients, and warned that colors, fragrances and some “plumping” ingredients can cause contact allergies or irritation. - A fragrance‑free formula with squalane, shea butter and vitamin E received high marks for hydration and neutrality from several testers. - Petroleum jelly (Vaseline) was noted as an effective occlusive that seals in moisture; dermatologists said petrolatum is generally non‑allergenic and can be useful after minor lip procedures. - A 1% hydrocortisone over‑the‑counter balm was found effective for relieving itching and cracking but was described as unsuitable for long‑term continuous use. - Tinted, flavored and SPF balms divided opinion: some testers praised hydration and subtle color or sun protection, while others reported drying pigments, taste issues or bleeding outside the lip line. Summary: The testing highlighted that different formulations offer different benefits: occlusives tend to seal moisture, oil‑based blends and emollients can feel more hydrating, and medicated or SPF products may add targeted benefits with potential for irritation. Experts also emphasized allergy risk from certain additives and recommended attention to product expiry. Undetermined at this time
