Sure! Here's a simple recipe for a homemade glycerin lip balm:

Ingredients:
- 1 tablespoon beeswax pellets
- 1 tablespoon shea butter
- 1 tablespoon coconut oil
- 1 teaspoon vegetable glycerin
- Optional: a few drops of your favorite essential oil (such as peppermint or lavender) for fragrance

Instructions:
1. In a double boiler or a heat-safe bowl placed over a pot of simmering water, melt the beeswax pellets, shea butter, and coconut oil together. Stir gently until fully melted and combined.
2. Remove the mixture from heat and let it cool slightly for a few minutes.
3. Add the vegetable glycerin and essential oil (if using) to the melted mixture. Stir well to incorporate all the ingredients evenly.
4. Carefully pour the mixture into lip balm tubes or small containers of your choice. Leave a little bit of space at the top to allow for the balm to settle.
5. Let the lip balm cool and solidify completely at room temperature. This may take a few hours.
6. Once solidified, cap the lip balm containers and they are ready to use!

Glycerin is a wonderful ingredient for lip balms as it helps to attract and retain moisture, keeping your lips hydrated and soft. The combination of beeswax, shea butter, and coconut oil provides nourishment and protection to the lips, while the optional essential oil adds a pleasant scent.

Remember to store your homemade lip balm in a cool, dry place, away from direct sunlight, to maintain its quality and effectiveness. Enjoy your all-natural glycerin lip balm!
