In a small bowl, whisk together 1/4 cup of witch hazel and 1 tablespoon of aloe vera gel until smooth.
Add 3–4 drops lavender essential oil and 1–2 drops peppermint essential oil. Whisk again.
Using a funnel, pour the mixture into a clean 4 oz glass spray bottle.
Store in a cool, dry place away from sunlight.
Give it a good shake before each use and spritz lightly over sun-exposed skin after a hot day.
