It's best to avoid petroleum-based lip balms and also ingredients that can be irritating (and toxic!), like synthetic fragrances, chemicals, preservatives, petrochemicals, phthalates, and synthetic colors.
Natural and simple ingredients are always more nourishing!
Some effective ways to help chapped lips include:
1. Applying organic topical oils such as jojoba, coconut, avocado, vitamin e, or shea butter several times a day and definitely before bed.
2. Consuming more healthy fats (especially omega 3 fatty acids) like flax oil, clary sage oil, and foods such as flax seeds, chia seeds, walnuts, almonds and avocados. If you're not a vegetarian or vegan then a high quality fish oil and cold water fish such as wild salmon are great sources of healthy omega 3s.
3. Drinking lots of filtered water-- you know you're sufficiently hydrated when your urine is a pale, straw color.
4. Using a humidifier, especially at night while sleeping.
Hope that's helpful!
